# WeChat Mini-Program Admin Scheduling/排课设置 - Complete Exploration Report
**Date**: 2026-04-05
**Project**: mp-pilates (WeChat mini-program for pilates studio bookings)
---
## 📋 Executive Summary
This is a **Pilates studio booking management system** with a comprehensive admin scheduling UI. The "排课设置" (Schedule Setup) feature allows admins to:
1. Define recurring weekly class templates (时间模板)
2. Manually add time slots for specific dates
3. Close slots (临时调整 → 关闭时段)
4. Batch generate slots from templates
The architecture uses:
- **Frontend**: Vue 3 + TypeScript (WeChat mini-program with Taro/UNI framework)
- **Backend**: NestJS + Prisma ORM
- **State Management**: Pinia (Vue state management)
- **Database**: Likely PostgreSQL/MySQL with Prisma

## 🔑 Key Components
### 1. **Admin Dashboard (index.vue)**
**File**: `packages/app/src/pages/admin/index.vue`
**Features**:
- Display stats: today's bookings, total orders, total bookings
- Navigation grid to 6 admin modules:
- 📅 **排课设置** → `/pages/admin/week-template`
- 🔧 **临时调整** → `/pages/admin/slot-adjust`
- 👥 **会员管理** → `/pages/admin/members`
- 📋 **订单管理** → `/pages/admin/orders`
- 💳 **卡种管理** → `/pages/admin/card-types`
- 🏢 **工作室设置** → `/pages/admin/studio`
**Key Functions**:
```typescript
- navigate(path): Navigates to admin pages
- loadStats(): Fetches dashboard statistics via adminStore.fetchDashboardStats()
```
**State**:
```typescript
const stats = ref<AdminStats>({ todayBookings: 0, totalOrders: 0, totalBookings: 0 })
const statsLoading = ref(false)
```
---
### 2. **Week Template Management (week-template.vue)** ✨ MAIN SCHEDULING UI
**File**: `packages/app/src/pages/admin/week-template.vue`
**Route**: `/pages/admin/week-template`
#### Purpose
Manage recurring weekly schedule templates. These are used to **auto-generate** time slots for future weeks.
#### Data Structure
```typescript
interface WeekTemplate {
readonly id: string
readonly dayOfWeek: number // 1=Mon, 2=Tue, ..., 7=Sun (ISO format)
readonly startTime: string // HH:MM format
readonly endTime: string // HH:MM format
readonly capacity: number // Max bookings per slot
readonly isActive: boolean // Enable/disable template
readonly createdAt: string
readonly updatedAt: string
}
```
#### UI Sections
1. **Toolbar**
- Display template count: "共 N 条模板"
- "+ 新增时段" (Add new slot) button
2. **Template List** (Grouped by weekday)
- Days are sorted (Monday → Sunday)
- Each day shows count: "3 个时段"
- Each template row displays:
- Time range: "09:00 – 10:00"
- Capacity: "10 人"
- Actions:
- Toggle button: "启用"/"停用" (Enable/Disable)
- "编辑" (Edit)
- "删除" (Delete)
- Inactive templates are grayed out (opacity: 0.5)
3. **Modal for Add/Edit**
- Star date picker (1-7 for weekday)
- Start time picker
- End time picker
- Capacity input (number)
- Validation: time and capacity required
- Cancel/Confirm buttons
4. **Save Bar** (Fixed at bottom)
- Only shows when `isDirty` flag is true
- "保存全部更改" button with loading state
#### Key Functions
```typescript
async fetchTemplates()
- Fetches all templates from backend
- Groups by dayOfWeek for display
- Clears isDirty flag
async handleSave()
- Maps local template state to API payload
- Calls adminStore.saveWeekTemplates(payload)
- Refreshes templates after save
- Shows success/error toast
function openAdd()
- Opens modal for creating new template
- Clears form
function openEdit(tpl)
- Opens modal in edit mode
- Populates form with existing values
function submitForm()
- Validates form (time and capacity required)
- Creates or updates template in memory
- Sets isDirty = true (triggers save bar)
function toggleTemplate(tpl)
- Toggles isActive flag
- Sets isDirty = true
function deleteTemplate(tpl)
- Shows confirmation modal
- Removes from array
- Sets isDirty = true
```
#### Local State Management
```typescript
const templates = ref<LocalTemplate[]>([])
const loading = ref(false)
const saving = ref(false)
const isDirty = ref(false) // Tracks unsaved changes
const showModal = ref(false)
const editTarget = ref<LocalTemplate | null>(null)
const form = ref({
dayIdx: 0, // Selected day index (0-6)
startTime: '09:00',
endTime: '10:00',
capacityStr: '10',
})
const grouped = computed(() => {
// Groups templates by dayOfWeek for rendering
return Object.fromEntries(
Object.entries(map).sort(([a], [b]) => Number(a) - Number(b))
)
})
```
#### Example: Adding a Monday 9AM-10AM class
1. User taps "+ 新增时段"
2. Modal opens, form is reset to defaults
3. User selects "周一" (Monday) from picker
4. User confirms times and capacity
5. New template object is pushed to `templates` array
6. `isDirty` is set to true → save bar appears
7. User taps "保存全部更改"
8. Store calls `PUT /admin/week-template` with all templates
9. Backend deletes all old templates and creates new ones
10. Frontend refetches and displays updated list
---
### 3. **Slot Adjustment (slot-adjust.vue)** - Temporary Slot Management
**File**: `packages/app/src/pages/admin/slot-adjust.vue`
**Route**: `/pages/admin/slot-adjust`
#### Purpose
Handle temporary/manual time slot operations:
1. Add one-off slots for specific dates
2. Close available slots
3. Batch-generate slots from templates
#### UI Structure (3 Tabs)
##### Tab 0: "新增时段" (Add Manual Slot)
- Date picker (defaults to today)
- Start/End time pickers
- Capacity input
- Submit button: "新增时段"
- **Endpoint**: `POST /admin/time-slot/manual`
```typescript
interface CreateManualSlotDto {
date: string // YYYY-MM-DD
startTime: string // HH:MM
endTime: string // HH:MM
capacity?: number // Defaults to DEFAULT_SLOT_CAPACITY (1)
}
```
##### Tab 1: "关闭时段" (Close Slots)
- Date picker (defaults to today)
- Loads all slots for selected date
- Displays slot list with:
- Time range
- Status badge (OPEN/FULL/CLOSED)
- Booked count: "X/Y"
- Close button (if not already closed)
- Confirmation modal when closing
- **Endpoint**: `PUT /admin/time-slot/:id/close`
**Slot Status Colors**:
```
OPEN → Green badge #27ae60
FULL → Orange badge #e67e22
CLOSED → Gray badge #999
```
##### Tab 2: "批量生成" (Batch Generate)
- Start date picker
- End date picker (defaults to +7 days)
- Hint: "将根据排课模板，自动生成所选日期范围内的时段"
- *"Will auto-generate slots for selected date range based on schedule template"*
- Submit button: "批量生成"
- **Endpoint**: `POST /admin/generate-slots`
**How it works**:
1. Frontend sends date range to backend
2. Backend fetches all **active** WeekTemplates
3. For each day in range, finds matching templates by weekday
4. Creates TimeSlot records with `source: TEMPLATE`
5. Uses `skipDuplicates: true` to avoid re-generating existing slots
```typescript
// Backend example: If templates include:
// - Monday: 09:00-10:00, 18:00-19:00 (2 templates)
// - Wednesday: 10:00-11:00 (1 template)
//
// And user selects 2026-04-05 to 2026-04-11:
// - Mon 04-06: 2 slots generated
// - Wed 04-08: 1 slot generated
// Total: 3 slots (if these dates fall in range)
```
#### Key Functions
```typescript
async submitAddSlot()
- POST /admin/time-slot/manual
- Shows success/error toast
async loadSlotsForClose()
- Fetches slots for closeDate via adminStore.fetchSlotsByDate(date)
- Sets slotsLoading flag
async closeSlot(slot)
- Confirmation modal
- PUT /admin/time-slot/:id/close
- Reloads slot list
async submitGenerate()
- POST /admin/generate-slots with date range
- Shows toast with count of generated slots
```
#### Local State
```typescript
const activeTab = ref(0) // 0=Add, 1=Close, 2=Generate
const submitting = ref(false)
const slotsLoading = ref(false)
// Tab 0: Add form
const addForm = ref({
date: formatDate(new Date()),
startTime: '09:00',
endTime: '10:00',
capacityStr: '10',
})
// Tab 1: Close slots
const closeDate = ref(formatDate(new Date()))
const daySlots = ref<TimeSlot[]>([])
// Tab 2: Generate form
const genForm = ref({
startDate: formatDate(new Date()),
endDate: formatDate(new Date(Date.now() + 7 * 86400000)), // +7 days
})
```

## 📊 Data Flow: "排课设置" User Journey
### Scenario: Admin sets up class schedule for next week
1. **Admin opens dashboard** → `index.vue`
- Taps "排课设置" nav item
2. **Admin navigates to Week Template page** → `week-template.vue`
- `onMounted()` → `fetchTemplates()`
- Frontend: `GET /admin/week-template`
- Shows existing templates grouped by day
- Example display:
```
周一
09:00-10:00 10人 [启用] [编辑] [删除]
18:00-19:00 8人 [启用] [编辑] [删除]
周三
10:00-11:00 12人 [启用] [编辑] [删除]
```
3. **Admin adds a new class** → Click "+ 新增时段"
- Modal opens
- Select day, time, capacity
- Click "确认"
- Template added to local `templates` array
- **Save bar appears** at bottom
4. **Admin edits existing template** → Click "编辑"
- Modal opens with existing values
- Modify time/capacity
- Click "确认"
- Updated in local array
- Save bar shows if changed
5. **Admin disables a template** → Click "停用"
- `isActive` flipped to false
- Template grayed out
- Save bar shows
6. **Admin saves all changes** → Click "保存全部更改"
- Loading state
- Frontend: `PUT /admin/week-template` with all templates
- Backend transaction:
```
BEGIN TRANSACTION
DELETE FROM week_template
INSERT INTO week_template (day_of_week, start_time, end_time, capacity, is_active) VALUES (...)
COMMIT TRANSACTION
```
- Success toast
- Frontend refetches templates
- Save bar disappears
7. **Backend scheduler auto-generates slots**
- Nightly cron (scheduler module)
- Calls `SlotGeneratorService.generateSlots(14)`
- Queries active WeekTemplates
- For each day in next 14 days:
- Checks what templates apply (by ISO weekday)
- Creates TimeSlot records
- Uses `skipDuplicates` to avoid duplicates on re-run
- Example output:
```
date: 2026-04-06 (Monday)
09:00-10:00 source=TEMPLATE templateId=abc123
18:00-19:00 source=TEMPLATE templateId=def456
date: 2026-04-08 (Wednesday)
10:00-11:00 source=TEMPLATE templateId=ghi789
```
8. **Members can see and book the generated slots**
- Frontend: `GET /time-slot/available?date=2026-04-06`
- Members choose a slot and confirm booking

## 📅 Constants & Utilities
### Shared Constants
**File**: `packages/shared/src/constants.ts`
```typescript
export const SLOT_GENERATION_DAYS = 14
// Number of days ahead to generate slots for
export const DEFAULT_SLOT_CAPACITY = 1
// Default capacity if not specified (for private lessons)
export const WEEKDAY_LABELS = ['', '周一', '周二', '周三', '周四', '周五', '周六', '周日']
// Index 0 is unused, 1-7 map to weekdays
// Used in dropdowns and display
export const DEFAULT_CANCEL_HOURS_LIMIT = 2
// Hours before slot to allow free cancellation
export const TIME_PERIODS = {
MORNING: { label: '上午', start: '06:00', end: '12:00' },
AFTERNOON: { label: '下午', start: '12:00', end: '18:00' },
EVENING: { label: '晚上', start: '18:00', end: '22:00' }
}
export const DATE_SELECTOR_DAYS = 7
```
### Format Utilities
**File**: `packages/app/src/utils/format.ts`
```typescript
formatDate(date: Date | string): string
// Converts to YYYY-MM-DD format
// Used for date pickers and API calls
getWeekdayLabel(date: Date | string): string
// Returns Chinese weekday (周一-周日)
isToday(date: Date | string): boolean
// Checks if date is today
getDateRange(days: number): Array<{ date, weekday, isToday }>
// Generates future N days' dates
```
### Request Utility
**File**: `packages/app/src/utils/request.ts`
```typescript
function request<T>(options: RequestOptions): Promise<T>
// Makes HTTP request with JWT auth
// Auto-refreshes token on 401
function get<T>(url: string, data?: Record<string, unknown>): Promise<T>
function post<T>(url: string, data?: Record<string, unknown>): Promise<T>
function put<T>(url: string, data?: Record<string, unknown>): Promise<T>
function del<T>(url: string, data?: Record<string, unknown>): Promise<T>
// Base URL logic:
// - Production: https://focus.richarjiang.com/api
// - Development: http://localhost:3000/api
```
---
## 🔐 Permission Model
**Role**: `UserRole.ADMIN`
### Protected Endpoints
All `/admin/*` endpoints require:
1. Valid JWT token
2. Header: `Authorization: Bearer <token>`
3. User role must be `ADMIN`
Protected by:
- `@UseGuards(JwtAuthGuard, RolesGuard)`
- `@Roles(UserRole.ADMIN)`
### Auth Flow
1. Admin logs in via auth module
2. JWT token returned, stored in `uni.setStorageSync('token')`
3. All requests include token in Authorization header
4. If 401 response: clear token, show login prompt
5. If 4xx/5xx: show error toast
---
## 🐛 Current Implementation Notes
### Implemented Features ✅
- [x] Week template CRUD (Create, Read, Update via replace)
- [x] Manual slot creation
- [x] Close individual slots
- [x] Batch slot generation from templates
- [x] UI for all three slot adjustment tabs
- [x] Local state change tracking (isDirty)
- [x] Modal form for adding/editing templates
- [x] Grouping templates by weekday
- [x] Status badges for slots (OPEN/FULL/CLOSED)
### Missing/Stub Features ⚠️
- [ ] `fetchDashboardStats()` API endpoint appears to be stubbed
- `index.vue` calls it but endpoint not found in backend
- May need to implement in studio or payment controller
- [ ] No client-side validation errors displayed on API failures
- [ ] No confirmation before overwriting all templates
- [ ] No undo/restore from past template versions
### Edge Cases to Watch 🔍
1. **Timezone handling**: All dates are treated as UTC midnight
- Slot generation uses `setUTCHours(0,0,0,0)`
- Frontend format displays as YYYY-MM-DD (local string)
2. **Duplicate slot prevention**:
- Backend uses `skipDuplicates: true` in createMany
- Assumes date + startTime + endTime forms unique key
3. **Template replacement is atomic**:
- All templates deleted, all new ones created in transaction
- If one row fails, entire operation rolls back
4. **ISO weekday vs JS getDay()**:
- Shared code uses ISO: 1=Mon, 7=Sun
- Frontend picker displays Chinese labels
- Backend slot-generator converts JS getDay() to ISO
---
## 📱 UI Design Patterns
### Colors & Styling
- **Primary**: `#1a1a2e` (dark navy)
- **Accent**: `#c9a87c` (gold)
- **Success**: `#27ae60` (green)
- **Warning**: `#e67e22` (orange)
- **Danger**: `#c0392b` (red)
- **Background**: `#f5f3f0` (light beige)
### Component Patterns
1. **Skeleton loaders**: Shimmer animation for loading states
2. **Save bar**: Fixed bottom bar shows only when changes exist
3. **Toggle buttons**: Color indicates state (on=green, off=orange)
4. **Modals**: Bottom-sheet style with backdrop
5. **Pickers**: WeChat native pickers for date/time
6. **Badges**: Color-coded status indicators
---
## 🚀 Deployment & Configuration
### Frontend
- WeChat mini-program environment
- Base URL logic in `packages/app/src/utils/request.ts`:
```typescript
// Production
https://focus.richarjiang.com/api
// Development
http://localhost:3000/api
```
### Backend
- NestJS server on port 3000
- Prisma ORM with database
- JWT authentication
- Role-based access control (RBAC)

## 🎯 Key Takeaways
1. **"排课设置"** is the master schedule template management page
2. **Templates are ISO-weekday based** (1=Monday, 7=Sunday)
3. **Slot generation is automated** via backend scheduler, triggered by:
- Nightly cron job
- Or manual POST to `/admin/generate-slots` endpoint
4. **Save pattern**: Local changes tracked, one "save all" API call with full template array
5. **Timezone**: All operations use UTC midnight as boundaries
6. **Atomicity**: Backend uses Prisma transactions for template replacement
7. **Permissions**: All admin endpoints protected by JWT + ADMIN role guard

## 📄 File-by-File Analysis
### 1️⃣ **pages/booking/index.vue** (Main Component)
**Template Structure:**
```
.booking-page
├── .sticky-header (z-index: 100)
│ ├── DateSelector (v-model="selectedDate")
│ └── TimePeriodFilter (v-model="selectedPeriod")
├── scroll-view.slot-scroll
│ ├── Loading skeleton (4 cards) - when loadingSlots
│ ├── Empty state - when no slots
│ └── SlotCard list - main content
│ └── SlotCard (v-for="slot in filteredSlots")
└── BookingConfirmPopup (conditional)
```
**Script Setup - State Variables:**
```typescript
selectedDate: ref<string> // YYYY-MM-DD format
selectedPeriod: ref<PeriodKey> // 'MORNING'|'AFTERNOON'|'EVENING'|null
showConfirmPopup: ref<boolean> // Modal visibility
pendingSlot: ref<Slot | null> // Slot being booked
refreshing: ref<boolean> // Pull-to-refresh state
```
**Computed Properties:**
```typescript
scrollHeight: computed(() => {
// Calculates scroll area height:
// windowHeight - headerHeight (220rpx) - tabbarHeight (100rpx)
// Converts rpx to pixels dynamically
})
filteredSlots: computed(() => {
// If no period selected: return all slots
// If period selected: filter by TIME_PERIODS[selectedPeriod].start/.end
// Compares slot.startTime with period.start and period.end
})
```
**Key Lifecycle - onMounted():**
```typescript
1. If logged in but no memberships fetched yet:
→ await userStore.fetchMemberships()
2. Load today's slots:
→ await loadSlots(formatDate(new Date()))
```
**Event Handlers:**
**onDateSelect(date: string)** → Changes selectedDate, calls loadSlots()
**onPeriodChange(period)** → Updates selectedPeriod (filtering is automatic via computed)
**onRefresh()** → Pull-to-refresh handler
```typescript
refreshing.value = true
await loadSlots(selectedDate.value)
refreshing.value = false
```
**onBookTap(slot)** → Book button clicked:
1. Check login status → show login modal if needed
2. Check hasValidMembership → show purchase modal if needed
3. Set pendingSlot = slot
4. Show BookingConfirmPopup
**onConfirmBooking(payload)** → User confirms booking:
```typescript
await bookingStore.createBooking(payload)
// payload: { timeSlotId, membershipId }
await loadSlots(selectedDate.value) // Refresh
```
**onCancelTap(slot)** → Cancel booking:
```typescript
if (!slot.myBookingId) return
// Show confirmation modal
await bookingStore.cancelBooking(slot.myBookingId)
await loadSlots(selectedDate.value) // Refresh
```
**Styles:**
- Page background: `#f5f3f0` (light beige)
- Sticky header with box-shadow
- Loading skeleton with shimmer animation
- Empty state centered with image
---
### 2️⃣ **stores/booking.ts** (State Management)
**State:**
```typescript
slots: ref<readonly TimeSlotWithBookingStatus[]>([])
myBookings: ref<readonly BookingWithDetails[]>([])
upcomingBookings: ref<readonly BookingWithDetails[]>([])
loadingSlots: ref<boolean>(false)
loadingBookings: ref<boolean>(false)
```
**Actions:**
**fetchSlots(date: string)**
```typescript
async function fetchSlots(date: string) {
loadingSlots.value = true
try {
slots.value = await get<TimeSlotWithBookingStatus[]>(
'/time-slot/available',
{ date } // ← date as query param
)
} catch (err) {
console.error('Fetch slots failed:', err)
slots.value = []
} finally {
loadingSlots.value = false
}
}
```
⚠️ **CRITICAL:** If request fails, slots.value becomes empty []
**createBooking(dto: CreateBookingDto)**
```typescript
// dto: { timeSlotId: string; membershipId: string }
const result = await post<BookingWithDetails>('/booking', dto)
return result
```
**cancelBooking(bookingId: string)**
```typescript
const result = await put<BookingWithDetails>(`/booking/${bookingId}/cancel`)
return result
```
**fetchMyBookings(status?: string)**
```typescript
const params = status ? { status } : {}
myBookings.value = await get<BookingWithDetails[]>('/booking/my', params)
```
**fetchUpcomingBookings()**
```typescript
upcomingBookings.value = await get<BookingWithDetails[]>('/booking/my/upcoming')
```
---
### 3️⃣ **components/SlotCard.vue** (Individual Slot)
**Props:**
```typescript
interface Props {
slot: TimeSlotWithBookingStatus
}
```
**Emits:**
```typescript
book: [slot] // User wants to book
cancel: [slot] // User wants to cancel
```
**Template Sections:**
**1. Time & Capacity:**
```vue
<text>{{ slot.startTime.slice(0, 5) }} - {{ slot.endTime.slice(0, 5) }}</text>
<!-- e.g., "09:00 - 10:00" -->
<view class="slot-capacity" :class="capacityClass">
{{ capacityLabel }}
</view>
```
**2. Action Buttons (4 States):**
**State A: OPEN + not booked by me**
```vue
<view class="btn btn-book">可预约</view>
<!-- Tan/brown button, emits: book -->
```
**State B: OPEN + booked by me**
```vue
<view class="badge-booked">已预约</view>
<view class="btn-cancel">取消</view>
<!-- Badge + cancel link, emits: cancel -->
```
**State C: FULL**
```vue
<view class="btn btn-disabled">已约满</view>
<!-- Gray disabled button -->
```
**State D: CLOSED**
```vue
<view class="btn btn-disabled">已关闭</view>
<!-- Gray disabled button -->
```
**3. Booked Indicator:**
```vue
<view v-if="slot.isBookedByMe" class="booked-bar" />
<!-- Tan bar on left side of card when booked by me -->
```
**Computed Properties:**
**capacityLabel:**
```typescript
if (status === CLOSED) return '已关闭'
return `${bookedCount}/${capacity} 人` // e.g., "0/1 人"
```
**capacityClass:** Determines background color
```
CLOSED → cap-closed (gray)

时间: 09:00 - 10:00
剩余: 1 个名额
```
**4. Membership Card Selection:**
**Case A: 1 membership**
```vue
<view class="card-item selected">
💳
{{ membership.cardType.name }}
剩余 {{ remainingTimes }} 次
✓
</view>
```
(Auto-selected, pre-filled)
**Case B: Multiple memberships**

selectedMembershipId.value = memberships[0].id
}
},
{ immediate: true }
)

---
### 7️⃣ **stores/user.ts** (User State)
**Key State:**
```typescript
user: ref<UserProfileResponse | null>(null)
memberships: ref<readonly MembershipWithCardType[]>([])
token: ref<string>(uni.getStorageSync('token'))
```
**Key Computed:**
```typescript
loggedIn: computed(() => !!token.value)
activeMemberships: computed(() =>
memberships.value.filter(m => m.status === MembershipStatus.ACTIVE)
)
hasValidMembership: computed(() => activeMemberships.value.length > 0)
```
**Key Actions:**
```typescript
async function login()
async function fetchMemberships()
// GET /membership/my
async function logout()
```
---
### 8️⃣ **utils/request.ts** (API Client)
**Base URL Logic:**
```typescript
const BASE_URL = (() => {
const { miniProgram } = uni.getAccountInfoSync()
if (miniProgram.envVersion !== 'develop') {
return 'https://focus.richarjiang.com/api'
}
return 'http://localhost:3000/api'
})()
```
**Main request() function:**
```typescript
function request<T>(options: RequestOptions): Promise<T> {
// 1. Get token from localStorage
const token = uni.getStorageSync('token')
// 2. Call uni.request with:
// - Authorization header (Bearer token)
// - Content-Type: application/json
// 3. Response handling:
// - 401 → Clear token, show "please login", reject
// - ≥400 → Extract error from response.message, reject
// - <400 & success: true → Resolve with data
// - <400 & success: false → Reject with message
// 4. Network fail → Reject with errMsg
}
export function get<T>(url, data?): Promise<T>
export function post<T>(url, data?): Promise<T>
export function put<T>(url, data?): Promise<T>
```
**⚠️ GET Request Issue:**
```typescript
// In get(), data becomes the request body
// But uni.request with GET should NOT have a body
// Query params should be in the URL string
// This might cause issues on some platforms!
```
---
### 9️⃣ **utils/format.ts** (Date Utilities)
```typescript
formatDate(date): string
// Returns YYYY-MM-DD
getWeekdayLabel(date): string
// Returns "周一", "周二", ..., "周日"
isToday(date): boolean
// Compares year/month/day
getDateRange(days: number): ReadonlyArray
// Returns array of:
// {
// date: YYYY-MM-DD,
// weekday: "周一" | "今天" (if i===0),
// isToday: boolean
// }
// Uses i * 86400000ms for date increment
```
---
## 🔍 Data Types Overview
### TimeSlotWithBookingStatus (Extended from TimeSlot)
```typescript
interface TimeSlotWithBookingStatus extends TimeSlot {
readonly isBookedByMe: boolean // Has user already booked?
readonly myBookingId: string | null // ID needed to cancel
}
interface TimeSlot {
readonly id: string // UUID
readonly date: string // YYYY-MM-DD
readonly startTime: string // HH:MM
readonly endTime: string // HH:MM
readonly capacity: number // Max people
readonly bookedCount: number // Already booked
readonly status: TimeSlotStatus // OPEN|FULL|CLOSED
readonly source: TimeSlotSource // TEMPLATE|MANUAL
readonly templateId: string | null
}
```
### MembershipWithCardType
```typescript
interface MembershipWithCardType {
readonly id: string
readonly cardType: CardType
readonly status: MembershipStatus // ACTIVE|EXPIRED|USED_UP
readonly remainingTimes: number | null
readonly expireDate: string // YYYY-MM-DD
}
```
### CreateBookingDto
```typescript
interface CreateBookingDto {
readonly timeSlotId: string
readonly membershipId: string
}
```

---
## ⚠️ Potential Issues & Problems
### 1. **GET Request Body Issue**
**File:** `utils/request.ts` in `get()` function
```typescript
export function get<T>(url: string, data?: Record<string, unknown>): Promise<T> {
return request<T>({ url, method: 'GET', data }) // ← data as body!
}
```
**Problem:** GET requests shouldn't have a body. Query params should be in the URL.
**Impact:** `/time-slot/available?date=2026-04-05` might not work on all platforms.
### 2. **Empty Slots Array on Error**
**File:** `stores/booking.ts`, `fetchSlots()`
```typescript
catch (err) {
console.error('Fetch slots failed:', err)
slots.value = [] // ← Clears state on error!
}
```
**Problem:** Network error → page shows "empty state" instead of error message.
**Impact:** Users can't tell if there's an error or truly no slots available.
### 3. **No Error Handling in Main Page**
**File:** `pages/booking/index.vue`, `loadSlots()`
```typescript
async function loadSlots(date: string) {
await bookingStore.fetchSlots(date)
// ← No error handling, no user feedback
}
```
**Problem:** If fetchSlots() fails, user sees empty page with no explanation.
### 4. **Manual Date Calculation**
**File:** `utils/format.ts`, `getDateRange()`
```typescript
const d = new Date(now.getTime() + i * 86400000)
```
**Problem:** Doesn't account for DST transitions. Using `Date.setDate()` would be safer.
### 5. **No Loading State for Slots**
**File:** `pages/booking/index.vue`
```typescript
<view v-if="bookingStore.loadingSlots && !refreshing" class="loading-wrap">
```
**Problem:** Skeleton appears only on initial load, not when changing dates or refreshing.
**Impact:** Date changes appear instant (good UX but confusing if slow network).
### 6. **Hardcoded Membership Message**
**File:** `components/BookingConfirmPopup.vue`
```typescript
确认后将从「{{ selectedMembership.cardType.name }}」扣除 1 次课时
// ← Always says "1 次" even if card might deduct different amounts
```
**Problem:** Doesn't show actual deduction amount if dynamic.

## 📊 Event Flow Sequence
```
1. PAGE LOAD (onMounted)
├─ Check: userStore.loggedIn?
├─ If yes & no memberships: fetchMemberships()
└─ loadSlots(today)
└─ GET /time-slot/available?date=today
└─ bookingStore.slots = [...]
└─ render SlotCard components
2. USER TAPS DATE
├─ selectedDate.value = newDate
└─ onDateSelect(newDate)
└─ loadSlots(newDate)
└─ fetchSlots()
3. USER FILTERS PERIOD
├─ selectedPeriod.value = MORNING|AFTERNOON|EVENING|null
└─ filteredSlots computed updates
└─ SlotCards re-render (no new API call)
4. USER PULLS TO REFRESH
├─ onRefresh()
└─ loadSlots(selectedDate.value)
5. USER TAPS "可预约" BUTTON
├─ onBookTap(slot)
├─ Check login (if not → login modal)
├─ Check membership (if not → purchase modal)
└─ Show BookingConfirmPopup
└─ Pre-select first membership
6. USER CONFIRMS BOOKING
├─ onConfirmBooking({timeSlotId, membershipId})
├─ POST /booking
│ └─ bookingStore.createBooking()
├─ Show success toast
└─ loadSlots(selectedDate.value) // Refresh
└─ Updated slot.isBookedByMe = true
7. USER TAPS "取消" BUTTON
├─ onCancelTap(slot)
├─ Confirm modal
├─ PUT /booking/:id/cancel
│ └─ bookingStore.cancelBooking()
├─ Show success toast
└─ loadSlots(selectedDate.value) // Refresh
└─ Updated slot.isBookedByMe = false
```

## 🧪 Testing Scenarios
### ✅ Happy Path
- [ ] Load page → today's slots display
- [ ] Tap date → slots for that date display
- [ ] Filter by period → slots filtered correctly
- [ ] Tap "可预约" → popup shows with correct time/date
- [ ] Select membership → deduction message updates
- [ ] Confirm → booking created, slot shows "已预约"
- [ ] Pull to refresh → slots reload
- [ ] Tap "取消" → booking cancelled, slot back to "可预约"
### ⚠️ Edge Cases
- [ ] No slots for date → empty state appears
- [ ] User not logged in → login modal shows
- [ ] No valid membership → purchase modal shows
- [ ] Network error → ??? (currently shows empty)
- [ ] Slot changes to FULL → button becomes disabled
- [ ] Slot changes to CLOSED → button becomes disabled
---
## 🔧 Integration Points
**From Backend:**
1. ✅ GET `/time-slot/available?date=...` → Returns slots
2. ✅ POST `/booking` → Create booking
3. ✅ PUT `/booking/:id/cancel` → Cancel booking
4. ✅ GET `/membership/my` → List memberships
5. ✅ Auth via Bearer token
**From Frontend:**
1. ✅ LocalStorage for token persistence
2. ✅ uni.showModal, uni.showToast for UI feedback
3. ✅ uni.getSystemInfoSync() for responsive sizing
4. ✅ uni.navigateTo() for page navigation
---
## 📱 Responsive Layout
**Design Breakpoint:**
- Base: 750rpx (WeChat standard width unit)
- Window height: dynamic via uni.getSystemInfoSync().windowHeight
**Scroll Area Height Calculation:**
```typescript
scrollHeight = windowHeight - headerHeight(220rpx) - tabbarHeight(100rpx)
= windowHeight - (220 * (windowWidth / 750)) - (100 * (windowWidth / 750))
```
**Sticky Header:**
- Position: sticky (CSS)
- Top: 0
- Z-index: 100
- Contains: DateSelector + TimePeriodFilter
---
## 🎯 Summary
The booking system is well-architected with:
- ✅ Clear separation of concerns (component, store, utils)
- ✅ Proper type safety with TypeScript
- ✅ Responsive date/time selection
- ✅ Membership-based booking validation
- ✅ Optimistic loading states
- ✅ Accessible UI patterns
But needs:
- ⚠️ Better error handling
- ⚠️ Fix GET request implementation
- ⚠️ Loading state during date/period changes
- ⚠️ Network error user feedback

# Booking Page - Quick Reference & Code Snippets
## 🚀 Quick Start: Understanding the Flow
### Where Slots Come From
```typescript
// 1. Store calls API
packages/app/src/stores/booking.ts:17-27
async function fetchSlots(date: string) {
loadingSlots.value = true
try {
// GET /time-slot/available?date=2026-04-05
slots.value = await get<TimeSlotWithBookingStatus[]>(
'/time-slot/available',
{ date }
)
} catch (err) {
console.error('Fetch slots failed:', err)
slots.value = [] // ⚠️ Clears on error!
} finally {
loadingSlots.value = false
}
}
```
### Where Time Periods Are Defined
```typescript
// packages/shared/src/constants.ts:11-15
export const TIME_PERIODS = {
MORNING: { label: '上午', start: '06:00', end: '12:00' },
AFTERNOON: { label: '下午', start: '12:00', end: '18:00' },
EVENING: { label: '晚上', start: '18:00', end: '22:00' },
} as const
```
### Where Filtering Happens
```typescript
// pages/booking/index.vue:94-103
const filteredSlots = computed<TimeSlotWithBookingStatus[]>(() => {
const slots = bookingStore.slots as TimeSlotWithBookingStatus[]
if (!selectedPeriod.value) return [...slots]
const period = TIME_PERIODS[selectedPeriod.value]
return slots.filter((slot) => {
const t = slot.startTime // "09:00", "10:00", etc
return t >= period.start && t < period.end
})
})
```
### Slot Rendering
```vue
<!-- pages/booking/index.vue:34-42 -->
<view v-else class="slot-list">
<SlotCard
v-for="slot in filteredSlots"
:key="slot.id"
:slot="slot"
@book="onBookTap"
@cancel="onCancelTap"
/>
</view>
```
---
## 🔍 Finding Specific Things
### Q: Where do the time slot types come from?
**A:** `packages/shared/src/types/time-slot.ts`
```typescript
interface TimeSlotWithBookingStatus extends TimeSlot {
readonly isBookedByMe: boolean // true if user booked it
readonly myBookingId: string | null // needed for cancellation
}
interface TimeSlot {
readonly id: string // UUID
readonly date: string // "2026-04-05"
readonly startTime: string // "09:00"
readonly endTime: string // "10:00"
readonly capacity: number // 1 (for private lessons)
readonly bookedCount: number // 0 or 1
readonly status: TimeSlotStatus // OPEN|FULL|CLOSED
readonly source: TimeSlotSource // TEMPLATE|MANUAL
readonly templateId: string | null
readonly createdAt: string
readonly updatedAt: string
}
```
### Q: Where is the membership selection happening?
**A:** `components/BookingConfirmPopup.vue:136-147`
```typescript
const selectedMembershipId = ref<string>('')
watch(
[() => props.visible, () => props.memberships],
([visible, memberships]) => {
if (visible && memberships.length > 0) {
selectedMembershipId.value = memberships[0].id // Auto-select first
}
},
{ immediate: true },
)
```
### Q: Where are the button states determined?
**A:** `components/SlotCard.vue:15-45`
```vue
<!-- OPEN + not booked by me -->
<template v-if="slot.status === TimeSlotStatus.OPEN && !slot.isBookedByMe">
<view class="btn btn-book" @tap.stop="emit('book', slot)">
<text class="btn-text">可预约</text>
</view>
</template>
<!-- OPEN + booked by me -->
<template v-else-if="slot.status === TimeSlotStatus.OPEN && slot.isBookedByMe">
<view class="booked-row">
<view class="badge-booked">
<text class="badge-text">已预约</text>
</view>
<view class="btn-cancel" @tap.stop="emit('cancel', slot)">
<text class="btn-cancel-text">取消</text>
</view>
</view>
</template>
<!-- FULL or CLOSED -->
<template v-else>
<view class="btn btn-disabled">
<text class="btn-text">
{{ slot.status === TimeSlotStatus.FULL ? '已约满' : '已关闭' }}
</text>
</view>
</template>
```
### Q: Where is the API request actually made?
**A:** `utils/request.ts:22-59`
```typescript
export function request<T>(options: RequestOptions): Promise<T> {
return new Promise((resolve, reject) => {
const token = uni.getStorageSync('token') as string
uni.request({
url: `${BASE_URL}${options.url}`, // BASE_URL = http://localhost:3000/api
method: options.method || 'GET',
data: options.data,
header: {
'Content-Type': 'application/json',
...(token ? { Authorization: `Bearer ${token}` } : {}),
...options.header,
},
success: (res) => {
if (res.statusCode === 401) {
uni.removeStorageSync('token')
uni.showToast({ title: '请重新登录', icon: 'none' })
reject(new Error('Unauthorized'))
return
}
if (res.statusCode >= 400) {
const body = res.data as ApiResponse<unknown>
reject(new Error(body?.message || `请求失败 (${res.statusCode})`))
return
}
const body = res.data as ApiResponse<T>
if (body.success) {
resolve(body.data as T) // ← Extract data from ApiResponse
} else {
reject(new Error(body.message || '请求失败'))
}
},
fail: (err) => {
reject(new Error(err.errMsg || '网络请求失败'))
},
})
})
}
```

## 🐛 Debugging Tips
### Tip 1: Check what's in the store
```typescript
// In browser console while in booking page:
console.log('Slots:', JSON.stringify(uni.$u.pinia.state.value.booking.slots, null, 2))
console.log('Selected period:', uni.$u.pinia.state.value.booking.selectedPeriod)
```
### Tip 2: Log slot filtering
```typescript
// Add to pages/booking/index.vue filteredSlots computed:
const filteredSlots = computed<TimeSlotWithBookingStatus[]>(() => {
const slots = bookingStore.slots as TimeSlotWithBookingStatus[]
if (!selectedPeriod.value) {
console.log('No period filter, showing all slots:', slots.length)
return [...slots]
}
const period = TIME_PERIODS[selectedPeriod.value]
console.log(`Filtering by ${selectedPeriod.value}:`, period)
console.log('All slot times:', slots.map(s => s.startTime))
const filtered = slots.filter((slot) => {
const t = slot.startTime
const matches = t >= period.start && t < period.end
if (!matches) console.log(`${t} not in [${period.start}, ${period.end})`)
return matches
})
console.log('Filtered result:', filtered.length)
return filtered
})
```
### Tip 3: Verify API response
```typescript
// In stores/booking.ts fetchSlots():
async function fetchSlots(date: string) {
loadingSlots.value = true
try {
console.log('Fetching slots for date:', date)
slots.value = await get<TimeSlotWithBookingStatus[]>(
'/time-slot/available',
{ date }
)
console.log('Received slots:', slots.value)
console.log('Slot count:', slots.value.length)
if (slots.value.length > 0) {
console.log('First slot:', JSON.stringify(slots.value[0], null, 2))
}
} catch (err) {
console.error('Fetch slots failed:', err)
slots.value = []
} finally {
loadingSlots.value = false
}
}
```
### Tip 4: Check network requests
```typescript
// Open WeChat DevTools → Network tab
// Look for GET request to /time-slot/available
// Check:
// ✓ URL has ?date=YYYY-MM-DD
// ✓ Authorization header exists
// ✓ Response status 200
// ✓ Response body has "success": true
```

## ❌ Common Issues & Solutions
### Issue 1: Slots not loading
**Symptoms:**
- Page shows "当日暂无可约时段" (no slots)
- No error message
**Check list:**
```typescript
// 1. Is API endpoint correct?
// Check: /time-slot/available?date=2026-04-05
// Should return TimeSlotWithBookingStatus[]
// 2. Is date format correct?
// Page sends: formatDate(new Date()) → "2026-04-05"
// API expects: "YYYY-MM-DD"
console.log(formatDate(new Date())) // Should output: "2026-04-05"
// 3. Is authentication working?
console.log('Token:', uni.getStorageSync('token'))
// 4. Check for errors in console
// If fetchSlots fails, slots.value becomes []
```
**Solution:**
```typescript
// In bookingStore.fetchSlots(), add error state:
const error = ref<string | null>(null)
async function fetchSlots(date: string) {
loadingSlots.value = true
error.value = null // Clear previous error
try {
slots.value = await get<TimeSlotWithBookingStatus[]>(
'/time-slot/available',
{ date }
)
} catch (err) {
console.error('Fetch slots failed:', err)
error.value = err instanceof Error ? err.message : '加载失败'
slots.value = []
} finally {
loadingSlots.value = false
}
}
// Then in page template:
<view v-if="error" class="error-wrap">
<text>{{ error }}</text>
<view @tap="loadSlots(selectedDate)">重试</view>
</view>
```
### Issue 2: Time period filtering not working
**Symptoms:**
- Select "上午" (morning) but all slots still show
- Or vice versa
**Check:**
```typescript
// 1. Verify TIME_PERIODS constant
console.log('TIME_PERIODS:', TIME_PERIODS)
// 2. Check selectedPeriod value
console.log('Selected period:', selectedPeriod.value)
// 3. Verify slot.startTime format
// Should be "HH:MM" like "09:00", not "09:00:00"
bookingStore.slots.forEach(slot => {
console.log('Slot time:', slot.startTime, 'format ok?', /^\d{2}:\d{2}$/.test(slot.startTime))
})
// 4. Test filtering manually
const slot = bookingStore.slots[0]
const period = TIME_PERIODS.MORNING
console.log(`${slot.startTime} >= ${period.start}?`, slot.startTime >= period.start)
console.log(`${slot.startTime} < ${period.end}?`, slot.startTime < period.end)
```
**Solution:**
```typescript
// If time format is "09:00:00", slice it:
const filteredSlots = computed<TimeSlotWithBookingStatus[]>(() => {
const slots = bookingStore.slots as TimeSlotWithBookingStatus[]
if (!selectedPeriod.value) return [...slots]
const period = TIME_PERIODS[selectedPeriod.value]
return slots.filter((slot) => {
// Ensure HH:MM format
const t = slot.startTime.slice(0, 5) // "09:00:00" → "09:00"
return t >= period.start && t < period.end
})
})
```
### Issue 3: Booking button not responding
**Symptoms:**
- Click "可预约" but nothing happens
- No modal appears
**Check:**
```typescript
// 1. Is slot.status correct?
console.log('Slot status:', slot.status)
// Should be "OPEN" to show book button
// 2. Is isBookedByMe false?
console.log('Is booked by me?', slot.isBookedByMe)
// Should be false to show book button
// 3. Is onBookTap being called?
// Add to pages/booking/index.vue:
async function onBookTap(slot: TimeSlotWithBookingStatus) {
console.log('Book tapped for slot:', slot) // ← Should log
// Rest of code...
}
// 4. Is userStore.loggedIn true?
console.log('Logged in?', userStore.loggedIn)
```
### Issue 4: Membership not showing in popup
**Symptoms:**
- Booking popup appears but no membership card shown
- "暂无可用会员卡" displayed
**Check:**
```typescript
// 1. Are memberships loaded?
console.log('Memberships:', userStore.memberships)
// 2. Are any memberships ACTIVE?
console.log('Active memberships:', userStore.activeMemberships)
console.log('Has valid membership?', userStore.hasValidMembership)
// 3. Are memberships passed to popup?
// In pages/booking/index.vue:
<BookingConfirmPopup
:memberships="userStore.activeMemberships as MembershipWithCardType[]"
...
/>
console.log('Popup passed memberships:', userStore.activeMemberships)
```
**Solution:**
```typescript
// In onMounted:
onMounted(async () => {
if (userStore.loggedIn && userStore.activeMemberships.length === 0) {
console.log('Fetching memberships...')
try {
await userStore.fetchMemberships()
console.log('Memberships loaded:', userStore.activeMemberships)
} catch (err) {
console.error('Failed to fetch memberships:', err)
uni.showToast({ title: '加载会员卡失败', icon: 'none' })
}
}
await loadSlots(selectedDate.value)
})
```

## 📊 Capacity Display Logic
### How Capacity Color is Determined
```typescript
// components/SlotCard.vue:69-81
const capacityLabel = computed(() => {
const { bookedCount, capacity, status } = props.slot
if (status === TimeSlotStatus.CLOSED) return '已关闭'
return `${bookedCount}/${capacity} 人`
})
const capacityClass = computed(() => {
const { bookedCount, capacity, status } = props.slot
if (status === TimeSlotStatus.CLOSED) return 'cap-closed'
if (status === TimeSlotStatus.FULL) return 'cap-full'
if (bookedCount >= capacity * 0.8) return 'cap-almost'
return 'cap-open'
})
// Color mapping in styles:
// cap-open: #f0faf3 bg, #4caf50 text (green) - <80% booked
// cap-almost: #fff8ed bg, #f59e0b text (orange) - ≥80% booked
// cap-full: #fef0f0 bg, #ef4444 text (red) - status: FULL
// cap-closed: #f5f5f5 bg, #999 text (gray) - status: CLOSED
```
### Example Calculations
```typescript
// Slot 1: capacity=1, bookedCount=0, status=OPEN
// 0/1 人 in green badge (0% booked)
// Slot 2: capacity=1, bookedCount=1, status=OPEN
// 1/1 人 in red badge (100% booked ≥ 80%)
// Slot 3: capacity=5, bookedCount=4, status=OPEN
// 4/5 人 in orange badge (80% booked ≥ 80%)
// Slot 4: capacity=5, bookedCount=3, status=OPEN
// 3/5 人 in green badge (60% booked < 80%)
```

## 🎯 Next Steps for Debugging
1. **Verify API Endpoint**
- Open DevTools → Network
- Check `/time-slot/available?date=...` request
- Confirm response has `"success": true`
- Confirm data array is not empty
2. **Check Store State**
- Add console.logs to bookingStore.fetchSlots()
- Verify slots are set correctly
- Check loadingSlots toggle
3. **Verify Computed Properties**
- Log filteredSlots in component
- Check if filtering logic works
- Verify slot.startTime format
4. **Test User Interaction**
- Click date item → verify onDateSelect fires
- Click period tab → verify onPeriodChange fires
- Click book button → verify onBookTap fires
- Check modals appear
5. **Check Mobile-Specific Issues**
- Test in WeChat DevTools
- Check rpx calculations
- Verify touch events work

## State Management
### Component State (week-template.vue)
```typescript
templates: LocalTemplate[] ◄─ Main data array
loading: boolean ◄─ Fetch state
saving: boolean ◄─ Save state
isDirty: boolean ◄─ "Save bar" trigger
showModal: boolean ◄─ Modal visibility
editTarget: LocalTemplate | null ◄─ Which template is being edited
form: { ◄─ Modal form data
dayIdx: number
startTime: string
endTime: string
capacityStr: string
}
grouped: Computed<Record<number, LocalTemplate[]>> ◄─ Grouped by dayOfWeek
```
### Store State (stores/admin.ts)
```typescript
weekTemplates: WeekTemplate[] ◄─ Cached from server
cardTypes: CardType[]
studioConfig: StudioConfig | null
// ...other admin state
```
## API Endpoints Summary

Index 6: 周日 (Sunday) ──► dayOfWeek = 7
```
### Backend Conversion (slot-generator.service.ts)
```typescript
JS getDay(): 0=Sun, 1=Mon, 2=Tue, ..., 6=Sat
│
▼ toIsoWeekday()
│
ISO weekday: 1=Mon, 2=Tue, ..., 7=Sun
```
## Timeline Example
```
TODAY: 2026-04-05 (Sunday)
Admin actions:
1. Sets up weekly templates for Mon-Fri
2. Taps "保存全部更改"
3. PUT /admin/week-template sent
Backend scheduler (daily at midnight):
4. Runs generateSlots(14)
5. Tomorrow is 2026-04-06 (Monday)
6. Generates slots for Apr 6-19 (next 14 days)
7. Creates TimeSlots based on active templates:
Generated slots:
2026-04-06 (Mon): 09:00-10:00, 18:00-19:00
2026-04-07 (Tue): (none if no templates)
2026-04-08 (Wed): 10:00-11:00
2026-04-09 (Thu): (none if no templates)
2026-04-10 (Fri): 18:00-20:00
2026-04-11 (Sat): (none - weekend)
2026-04-12 (Sun): (none - weekend)
...repeats until 2026-04-19
Members can book from Apr 6 onwards

## 📊 Core Entities
### WeekTemplate (Database)
```typescript
id: string // UUID
dayOfWeek: number // 1=Mon, 2=Tue, ..., 7=Sun
startTime: string // "09:00"
endTime: string // "10:00"
capacity: number // Max bookings
isActive: boolean // Enabled/disabled
createdAt: string
updatedAt: string
```
### TimeSlot (Database)

id: string
date: string // YYYY-MM-DD
startTime: string
endTime: string
capacity: number
bookedCount: number // How many booked
status: "OPEN" | "FULL" | "CLOSED"

templateId: string | null // Links to WeekTemplate
createdAt: string
updatedAt: string
```
---
## 🌐 API Endpoints
### GET /admin/week-template

```json
[
{
"id": "uuid1",
"dayOfWeek": 1,
"startTime": "09:00",
"endTime": "10:00",
"capacity": 10,
"isActive": true,

}
]
```
### PUT /admin/week-template
Replace all templates (atomic transaction)
```json
{
"templates": [
{ "dayOfWeek": 1, "startTime": "09:00", "endTime": "10:00", "capacity": 10, "isActive": true },
{ "dayOfWeek": 1, "startTime": "18:00", "endTime": "19:00", "capacity": 8, "isActive": true },

]
}
```
### POST /admin/time-slot/manual

}
```
### PUT /admin/time-slot/:id/close
Close a slot (changes status to CLOSED)
### POST /admin/generate-slots
Generate slots for next 14 days from active templates
Response: `{ "count": 28 }`
---
## 🎨 UI State Management
### week-template.vue Local State
```typescript
// Main data
templates: LocalTemplate[] // All templates
grouped: Computed<Record<number, LocalTemplate[]>> // By dayOfWeek
// UI states
loading: boolean // Initial fetch
saving: boolean // Save in progress
isDirty: boolean // Show save bar?
showModal: boolean // Show add/edit modal?
editTarget: LocalTemplate | null // Editing which template?
// Modal form
form: {
dayIdx: number // 0-6 (picker index)
startTime: string // "09:00"
endTime: string // "10:00"
capacityStr: string // User input as string
}
```
### Key Computed
```typescript
const grouped = computed(() => {
// Groups templates by dayOfWeek for rendering
// Sorts by day number ascending (1-7)
// Returns: { 1: [...], 3: [...], 5: [...], ... }
})
```
---
## 🔐 Permissions & Auth
All `/admin/*` endpoints require:
1. Valid JWT token in `Authorization: Bearer <token>` header
2. User role must be `UserRole.ADMIN`
3. Guards: `@UseGuards(JwtAuthGuard, RolesGuard)`
---
## 🧮 Important Constants
From `packages/shared/src/constants.ts`:
```typescript
SLOT_GENERATION_DAYS = 14 // Generate 14 days ahead
DEFAULT_SLOT_CAPACITY = 1 // Private lesson default
DEFAULT_CANCEL_HOURS_LIMIT = 2 // Cancel up to 2 hours before
WEEKDAY_LABELS = [
'', // index 0 (unused)
'周一', // index 1 → dayOfWeek 1 (Monday)
'周二', // index 2 → dayOfWeek 2
'周三', // ... etc
'周四',
'周五',
'周六',
'周日' // index 7 → dayOfWeek 7 (Sunday)
]
```
---
## 🐛 Common Gotchas
### 1. dayOfWeek vs JS getDay()
- **Frontend uses**: ISO weekday (1=Mon, 7=Sun)
- **JS Date.getDay()**: 0=Sun, 6=Sat
- **Backend converts**: `toIsoWeekday()` in slot-generator.service.ts
### 2. Template Replace (Not Merge)
- `PUT /admin/week-template` **deletes all** and creates new
- NOT a merge/patch operation
- Frontend must send complete array
### 3. isDirty Flag
- Tracks **any** change locally (add/edit/delete/toggle)
- Used to show/hide save bar
- Cleared after successful save
### 4. Timezone
- All dates stored as UTC midnight: `setUTCHours(0,0,0,0)`
- Frontend displays as local YYYY-MM-DD strings
- May cause off-by-one on day boundaries
### 5. Slot Generation
- Uses `skipDuplicates: true` in Prisma
- Safe to re-run without creating duplicates
- Assumes `date + startTime + endTime` is unique
---
## 💡 Usage Example: Add a Monday 9AM Class
**Frontend (week-template.vue)**:
```typescript
// User clicks "+ 新增时段"
openAdd()
form.value = { dayIdx: 0, startTime: '09:00', endTime: '10:00', capacityStr: '10' }
showModal.value = true
// User confirms in modal
submitForm()
templates.value.push({
_key: String(Date.now()),
dayOfWeek: 1, // dayOptions[0].value = Monday
startTime: '09:00',
endTime: '10:00',
capacity: 10,
isActive: true
})
isDirty.value = true // ← Save bar appears
// User taps "保存全部更改"
handleSave()
payload = templates.value.map(t => ({...}))
await adminStore.saveWeekTemplates(payload)
// Backend creates transaction:
// DELETE FROM week_template
// INSERT INTO week_template (day_of_week, start_time, end_time, capacity, is_active)
// VALUES (1, '09:00', '10:00', 10, true)
// ... (all other templates)
// Frontend refetches and displays

## 📈 Scalability Notes
### Current Approach
- Templates: Small dataset (typically < 50 records)
- Slots: Generated in batches (14 days at a time)
- Uses `skipDuplicates` to handle reruns safely
### Bottlenecks
- Template replacement deletes ALL and creates NEW (atomic but slow with 1000s)
- Slot generation is serial (could be parallelized)
- No pagination for templates (assumes all fit in memory)
### Future Improvements
- Batch template updates (don't replace all)
- Pagination if templates > 100
- Incremental slot generation (detect last generated date)

├─ For next 14 days:
│
│ Day 0: Tue (ISO 2) → no matching template → skip
│ Day 1: Wed (ISO 3) → no matching template → skip

## 📋 System Overview
### What It Does
This system manages the complete lifecycle of time slots and bookings for a pilates studio:
1. **Automated Slot Generation**: Every day at 02:00 UTC, generates 14 days of time slots from reusable weekly templates
2. **Capacity Management**: Tracks slot capacity and prevents overbooking
3. **Booking Management**: Allows members to book slots with their memberships
4. **Cancellation & Refunds**: Members can cancel with conditional refunds (within 2-hour window)
5. **Membership Expiration**: Automatically expires memberships by date or used sessions
6. **Cleanup**: Marks past slots as closed and completed bookings as finished
### Key Concepts
- **WeekTemplate**: Defines recurring schedule (e.g., "Monday 09:00-10:00")
- **TimeSlot**: Individual class instance (e.g., "April 10, 2026 09:00-10:00")
- **Booking**: User's reservation (links user + slot + membership)
- **Status Tracking**: OPEN → FULL → CLOSED (slots) and CONFIRMED → COMPLETED (bookings)
### Architecture Highlights
✅ **Idempotent** - Safe to re-run slot generation
✅ **Transactional** - ACID compliance for bookings
✅ **Automated** - 4 daily cron jobs maintain state
✅ **Flexible** - Supports TIMES, DURATION, and TRIAL memberships
✅ **Scalable** - Batch operations, proper database indexes
✅ **Secure** - Role-based access, comprehensive validation

## ❓ FAQ
**Q: Where do time slots come from?**
A: Auto-generated from WeekTemplates every day at 02:00 UTC by `generateSlots(14)`.
**Q: Can I disable slot generation?**
A: Yes, make templates `isActive: false` or disable the cron job in `scheduler.service.ts`.
**Q: How is capacity managed?**
A: `bookedCount` increments on booking, slot status becomes FULL when `bookedCount >= capacity`.
**Q: What if I cancel a booking?**
A: `bookedCount` decrements; if within 2-hour window, membership refunded; slot status restored if was FULL.
**Q: Timezone support?**
A: All times stored in UTC. Scheduler uses UTC times (02:00, 02:30, etc.). See DIAGRAMS § 7.
**Q: How are memberships expired?**
A: Automatically by scheduler job at 03:00 UTC daily; marks EXPIRED if date passed or USED_UP if sessions depleted.

## Key Concepts
### WeekTemplate
Defines **recurring class schedule** by day of week (1=Monday, 7=Sunday) and time.
- Used to auto-generate TimeSlots nightly
- Can be enabled/disabled
- Has capacity (default 1 for private lessons)
### TimeSlot
**Individual class instance** on a specific date with a specific time.
- Status: OPEN → FULL → CLOSED
- Source: TEMPLATE (auto-generated) or MANUAL (admin-created)
- Cannot have duplicates (unique constraint on date+startTime+endTime)
### Booking
**User's reservation** for a specific TimeSlot.
- Status: CONFIRMED → COMPLETED (or CANCELLED)
- Links user + timeSlot + membership
- Unique constraint: one booking per user per slot
---
## Daily Scheduler Jobs
All times in UTC:
| Time | Job | What It Does |
|------|-----|--------------|
| **02:00** | `handleSlotGeneration()` | Generate slots 14 days ahead from WeekTemplates |
| **02:30** | `handleCleanupSlots()` | Mark past OPEN slots as CLOSED |
| **03:00** | `handleCheckMemberships()` | Expire memberships by date or used-up sessions |
| **22:00** | `handleCompleteBookings()` | Mark past CONFIRMED bookings as COMPLETED |
---
## Important Methods
### SlotGeneratorService
```typescript
// Generate N days of slots from WeekTemplates
generateSlots(daysAhead = 14): Promise<number>
// Close all past OPEN slots
cleanupExpiredSlots(): Promise<number>
// Expire memberships by date or session count
checkExpiredMemberships(): Promise<number>
// Mark past bookings as COMPLETED
completeBookings(): Promise<number>
```
### TimeSlotService
```typescript
// Get all slots for a date (with user's booking status if provided)
getAvailableSlots(date: string, userId?: string): Promise<TimeSlotWithBookingStatus[]>
// Manually create a one-off slot
createManualSlot(dto: CreateManualSlotDto): Promise<TimeSlot>
// Close a slot (prevent new bookings)
closeSlot(id: string): Promise<TimeSlot>
// Get/replace weekly templates
getWeekTemplates(): Promise<WeekTemplate[]>
replaceWeekTemplates(items: WeekTemplateItemDto[]): Promise<CreateBatchPayload>
```
### BookingService
```typescript
// Create a booking (validates slot/membership, updates counts)
createBooking(userId: string, dto: CreateBookingDto): Promise<BookingWithRelations>
// Cancel a booking (conditionally refunds membership)
cancelBooking(userId: string, bookingId: string): Promise<CancelBookingResult>
// Get user's bookings (paginated, filterable by status)
getMyBookings(userId: string, status?, page, limit): Promise<PaginatedResult>
// Get all CONFIRMED bookings for dates >= today
getUpcomingBookings(userId: string): Promise<BookingWithRelations[]>
```
---
## API Endpoints
### Member Endpoints
```
GET /time-slot/available?date=2026-04-10
→ Returns slots for that date with user's booking status
GET /time-slot/:id
→ Returns full slot details with all bookings
POST /booking
Body: { "timeSlotId": "uuid", "membershipId": "uuid" }
→ Create a booking
PUT /booking/:id/cancel
→ Cancel a booking (refund if within window)
GET /booking/my?status=CONFIRMED&page=1&limit=10
→ Get user's bookings (paginated)
GET /booking/my/upcoming
→ Get all upcoming CONFIRMED bookings
```
### Admin Endpoints
```
GET /admin/week-template
→ List all templates
PUT /admin/week-template
Body: { "templates": [ {...}, {...} ] }
→ Replace all templates (atomic)
POST /admin/time-slot/manual
Body: { "date", "startTime", "endTime", "capacity" }
→ Create a one-off slot
PUT /admin/time-slot/:id/close
→ Close a slot
POST /admin/generate-slots
→ Manually trigger slot generation
GET /admin/bookings?page=1&limit=10&status=CONFIRMED

```
---
## Status Values
### TimeSlotStatus
- **OPEN**: Accepts bookings (bookedCount < capacity)
- **FULL**: At capacity (bookedCount >= capacity)
- **CLOSED**: Past date or manually closed
### BookingStatus
- **CONFIRMED**: Active reservation
- **CANCELLED**: User cancelled
- **COMPLETED**: Slot time has passed
- **NO_SHOW**: Marked manually
### MembershipStatus
- **ACTIVE**: Valid for booking
- **EXPIRED**: End date passed
- **USED_UP**: No remaining sessions (for TIMES/TRIAL)
### CardTypeCategory
- **TIMES**: N sessions (e.g., "5-pack")
- **DURATION**: Valid for X days (e.g., "1-month")
- **TRIAL**: Free trial sessions
---
## Key Logic
### Booking Creation Transaction
```
1. Validate TimeSlot exists and status = OPEN
2. Check user not already booked this slot
3. Validate Membership:
- Belongs to user
- Status = ACTIVE
- Has capacity:
* TIMES/TRIAL: remainingTimes > 0
* DURATION: expireDate > NOW
4. CREATE Booking(CONFIRMED)
5. UPDATE TimeSlot:
- bookedCount++
- IF bookedCount >= capacity THEN status = FULL
6. UPDATE Membership (if time-based):
- remainingTimes--
- IF remainingTimes = 0 THEN status = USED_UP
7. Return with relations
```
### Cancellation Refund Logic
```
cancelHoursLimit = 2 (configurable in StudioConfig)
slotStartTime = TimeSlot.date + TimeSlot.startTime
deadline = NOW + (cancelHoursLimit * hours)
IF slotStartTime >= deadline:
Refund = TRUE
Increment membership.remainingTimes
ELSE:
Refund = FALSE
No membership change
```
---
## Weekday Mapping
**ISO Standard** (what WeekTemplate uses):
```
1 = Monday
2 = Tuesday
3 = Wednesday
4 = Thursday
5 = Friday
6 = Saturday
7 = Sunday
```
**JavaScript getDay()** (what Date does):
```
0 = Sunday
1 = Monday
2 = Tuesday
...
6 = Saturday
```
**Conversion function:**
```typescript
function toIsoWeekday(jsDay: number): number {
return jsDay === 0 ? 7 : jsDay
}
```
---
## Database Constraints
### TimeSlot
- Unique: `[date, startTime, endTime]` - prevents duplicate slots
- Index: `date` - for date range queries
- Index: `status` - for filtering
### Booking
- Unique: `[userId, timeSlotId]` - one booking per user per slot
- Index: `userId` - for user's bookings
- Index: `status` - for status filtering
---
## Configuration
### Environment Variables
```
DATABASE_URL=mysql://... (required)
```
### From StudioConfig Table
```
cancelHoursLimit = 2 (hours before slot to allow free cancellation)
```
### From Shared Constants
```
DEFAULT_SLOT_CAPACITY = 1
SLOT_GENERATION_DAYS = 14
DEFAULT_CANCEL_HOURS_LIMIT = 2
```
---
## Common Errors
| Error | Cause | Solution |
|-------|-------|----------|
| TimeSlot not found | Invalid slot ID | Check slot exists |
| TimeSlot is not available | Status ≠ OPEN | Slot is FULL or CLOSED |
| You have already booked this slot | Duplicate booking | Check user's bookings |
| This membership does not belong to you | Membership not user's | Verify membership |
| Membership is not active | Status ≠ ACTIVE | Renew or purchase membership |
| No remaining times on this membership | remainingTimes ≤ 0 | Purchase more sessions |
| Membership has expired | expireDate < NOW | Renew membership |
| Cannot cancel booking with status | Status ≠ CONFIRMED | Can only cancel CONFIRMED bookings |
---
## Testing
Run tests with:
```bash
npm test -- slot-generator.service.spec.ts
npm test -- booking.service.spec.ts
npm test -- time-slot.service.spec.ts
```
Key test areas:
- Slot generation from templates
- Weekday mapping (JS vs ISO)
- Booking creation with all validations
- Cancellation with/without refund
- Membership expiration
---
## Performance Tips
1. **Avoid N+1 queries** - Always include relations in findMany
2. **Batch operations** - Use createMany/updateMany for large operations
3. **Transactions** - Wrap multi-step operations to prevent race conditions
4. **Indexes** - Queries filter by date and status (both indexed)
---
## Development Workflow
1. **Setup templates** → `PUT /admin/week-template`
2. **Manually trigger generation** → `POST /admin/generate-slots`
3. **View available slots** → `GET /time-slot/available?date=...`
4. **Create booking** → `POST /booking`
5. **Cancel booking** → `PUT /booking/:id/cancel`
For testing without scheduler:
```typescript
// Inject SlotGeneratorService and call directly
const count = await slotGenerator.generateSlots(7)
```
---
## Architecture Highlights
✅ **Idempotent** - Safe to re-run slot generation
✅ **Transactional** - Bookings are atomic
✅ **Automated** - 4 daily cron jobs maintain state
✅ **Flexible** - Supports multiple membership types
✅ **Scalable** - Batch operations, proper indexes
✅ **Validating** - DTO decorators + business logic checks

# NestJS Time-Slot & Scheduling System Analysis
## Executive Summary
This is a comprehensive analysis of the pilates studio booking system's time-slot generation and scheduling backend. The system automatically generates time slots from reusable weekly templates, maintains their lifecycle, and integrates tightly with the booking and membership management systems.
---
## 1. Data Models (Prisma Schema)
### 1.1 WeekTemplate Model
**Location:** `packages/server/prisma/schema.prisma` (lines 113-126)
```prisma
model WeekTemplate {
id String @id @default(uuid())
dayOfWeek Int @map("day_of_week") // 1=Mon, 7=Sun (ISO standard)
startTime String @map("start_time") // e.g., "09:00"
endTime String @map("end_time") // e.g., "10:00"
capacity Int @default(1) // Max participants
isActive Boolean @default(true) // Enable/disable template
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
timeSlots TimeSlot[] // Generated slots from this template
}
```
**Purpose:**
- Defines recurring time slots by day of week and time
- Used as blueprint for automatic slot generation
- Capacity defines how many people can book each slot
**Key Constraints:**
- `dayOfWeek` uses **ISO 8601 standard** (1=Monday through 7=Sunday)
- NOT JavaScript getDay() (0=Sunday)
- Conversion happens in SlotGeneratorService.toIsoWeekday()
---
### 1.2 TimeSlot Model
**Location:** `packages/server/prisma/schema.prisma` (lines 128-148)
```prisma
model TimeSlot {
id String @id @default(uuid())
date DateTime @db.Date // Calendar date (midnight UTC)
startTime String @map("start_time") // "HH:mm" format
endTime String @map("end_time") // "HH:mm" format
capacity Int @default(1) // Max participants
bookedCount Int @default(0) // Current bookings
status TimeSlotStatus @default(OPEN) // OPEN | FULL | CLOSED
source TimeSlotSource @default(TEMPLATE) // TEMPLATE | MANUAL
templateId String? @map("template_id") // Reference to WeekTemplate
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
template WeekTemplate? @relation(fields: [templateId], references: [id])
bookings Booking[]
@@unique([date, startTime, endTime]) // Prevent duplicate slots
@@index([date])
@@index([status])
}
```
**Status Lifecycle:**
- **OPEN**: Accepts bookings, bookedCount < capacity
- **FULL**: No more bookings, bookedCount >= capacity
- **CLOSED**: Past date or manually closed, no bookings allowed
**Source Types:**
- **TEMPLATE**: Auto-generated from WeekTemplate
- **MANUAL**: Created directly by admin
---
### 1.3 Booking Model
**Location:** `packages/server/prisma/schema.prisma` (lines 150-168)
```prisma
model Booking {
id String @id @default(uuid())
userId String @map("user_id")
timeSlotId String @map("time_slot_id")
membershipId String @map("membership_id")
status BookingStatus @default(CONFIRMED)
cancelledAt DateTime? @map("cancelled_at")
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
user User @relation(fields: [userId], references: [id])
timeSlot TimeSlot @relation(fields: [timeSlotId], references: [id])
membership Membership @relation(fields: [membershipId], references: [id])
@@unique([userId, timeSlotId]) // One booking per user per slot
@@index([userId])
@@index([status])
}
```
**Booking Status Values:**
- **CONFIRMED**: Active reservation
- **CANCELLED**: User cancelled
- **COMPLETED**: Slot time has passed
- **NO_SHOW**: Marked manually if user didn't attend
---
## 2. SlotGeneratorService
**Location:** `packages/server/src/time-slot/slot-generator.service.ts`
### 2.1 Service Overview
Core service responsible for:
1. **Generating** time slots from WeekTemplate
2. **Cleaning up** expired slots
3. **Managing** membership expiration
4. **Marking** past bookings as completed
### 2.2 Key Methods
#### `generateSlots(daysAhead: number = 14): Promise<number>`
**Purpose:** Creates time slots for the next N days based on active WeekTemplates.
**Algorithm:**
```
1. Fetch all active WeekTemplates (isActive = true)
2. Calculate tomorrow at midnight UTC as start date
3. For each day in [tomorrow, tomorrow + daysAhead):
a. Get ISO weekday (1-7) from JavaScript date
b. Find matching templates for this weekday
c. For each matching template, create slot data:
- date: UTC midnight
- startTime/endTime: from template
- capacity: from template
- source: TimeSlotSource.TEMPLATE
- templateId: template.id
4. Batch create all slots using createMany() with skipDuplicates: true
5. Return count of newly created slots
```
**Key Features:**
- **Idempotent:** Re-running is safe; duplicate date+startTime+endTime combos are skipped
- **Timezone Aware:** Uses UTC midnight for dates
- **Weekday Mapping:** Converts JS getDay() → ISO weekday
- **Batch Insert:** Creates all slots in single database operation
**Example Execution:**
- Today: Monday, April 7, 2026
- Daylight: 14 days
- Template: Monday 09:00-10:00, Friday 18:00-19:00
- Result: 2 slots tomorrow (Monday), 0 Wed-Thu, 1 Friday, repeat pattern
---
#### `cleanupExpiredSlots(): Promise<number>`
**Purpose:** Marks all OPEN slots with dates before today as CLOSED.
**Logic:**
```sql
UPDATE time_slots
SET status = 'CLOSED'
WHERE status = 'OPEN' AND date < TODAY_MIDNIGHT_UTC
```
**Returns:** Count of slots closed.
---
#### `checkExpiredMemberships(): Promise<number>`
**Purpose:** Manages membership expiration in two ways:
1. **By Expiration Date:**
```
WHERE status = ACTIVE AND expireDate < NOW
SET status = EXPIRED
```
2. **By Used-Up Sessions:**
```
WHERE status = ACTIVE AND remainingTimes = 0
SET status = USED_UP
```
**Returns:** Total count of memberships updated.
---
#### `completeBookings(): Promise<number>`
**Purpose:** Marks CONFIRMED bookings for past time slots as COMPLETED.
**Logic:**
```sql
UPDATE bookings
SET status = 'COMPLETED'
WHERE status = 'CONFIRMED'
AND timeSlot.date < TODAY_MIDNIGHT_UTC
```
---
## 3. TimeSlotService
**Location:** `packages/server/src/time-slot/time-slot.service.ts`
### 3.1 Service Overview
Handles time slot queries and management for both members and admins.
### 3.2 Key Methods
#### `getAvailableSlots(date: string, userId?: string): Promise<TimeSlotWithBookingStatus[]>`
**Purpose:** Retrieve all non-closed slots for a specific date, optionally including user's booking status.
**Query Logic:**
```
1. Parse date string to Date object
2. Find all slots for that calendar day:
- WHERE status != CLOSED
- ORDER BY startTime ASC
3. If userId provided:
- Include bookings where userId=X AND status=CONFIRMED
- Map to "isBookedByMe" and "myBookingId" fields
4. Return TimeSlotWithBookingStatus[]
```
**Response Type:**
```typescript
interface TimeSlotWithBookingStatus {
id: string
date: string // ISO date "YYYY-MM-DD"
startTime: string // "HH:mm"
endTime: string
capacity: number
bookedCount: number
status: TimeSlotStatus // OPEN | FULL | CLOSED
source: TimeSlotSource // TEMPLATE | MANUAL
templateId: string | null
createdAt: string // ISO datetime
updatedAt: string
isBookedByMe: boolean // Current user's booking?
myBookingId: string | null // For cancellation
}
```
---
#### `getSlotById(id: string): Promise<TimeSlot>`
Returns full slot details including all bookings. Throws NotFoundException if not found.
---
#### `createManualSlot(dto: CreateManualSlotDto): Promise<TimeSlot>`
**Purpose:** Allow admins to create one-off time slots outside templates.
**DTO:**
```typescript
class CreateManualSlotDto {
date: string // "YYYY-MM-DD"
startTime: string // "HH:mm"
endTime: string // "HH:mm"
capacity?: number // Defaults to DEFAULT_SLOT_CAPACITY (1)
}
```
**Creates slot with:**
- `source: TimeSlotSource.MANUAL`
- `templateId: null`
---
#### `closeSlot(id: string): Promise<TimeSlot>`
Sets slot status to CLOSED. Prevents new bookings but keeps existing ones.
---
#### `getWeekTemplates(): Promise<WeekTemplate[]>`
Lists all templates ordered by dayOfWeek and startTime.
---
#### `replaceWeekTemplates(items: WeekTemplateItemDto[]): Promise<CreateBatchPayload>`
**Purpose:** Atomic replacement of all templates (used during admin config).
**Transaction:**
```
1. DELETE FROM week_templates (all rows)
2. CREATE week_templates with new items
3. Return count
```
---
## 4. TimeSlotController & AdminTimeSlotController
**Location:** `packages/server/src/time-slot/time-slot.controller.ts`
### 4.1 Member Endpoints
#### `GET /time-slot/available?date=YYYY-MM-DD`
- Returns available slots for the date
- Includes current user's booking status
- Requires JWT authentication
#### `GET /time-slot/:id`
- Returns full slot details with all bookings
- Requires JWT authentication
---
### 4.2 Admin Endpoints
All require `@Roles(UserRole.ADMIN)` and JWT auth.
#### `GET /admin/week-template`
Lists all WeekTemplate entries.
#### `PUT /admin/week-template`
Replaces all templates. Request body:
```json
{
"templates": [
{
"dayOfWeek": 1,
"startTime": "09:00",
"endTime": "10:00",
"capacity": 1,
"isActive": true
}
]
}
```
#### `POST /admin/time-slot/manual`
Creates a manual slot. Request body:
```json
{
"date": "2026-04-10",
"startTime": "14:00",
"endTime": "15:00",
"capacity": 2
}
```
#### `PUT /admin/time-slot/:id/close`
Closes a specific slot.
#### `POST /admin/generate-slots`
Manually trigger slot generation (default 14 days ahead).
---
## 5. SchedulerService - Automated Jobs
**Location:** `packages/server/src/scheduler/scheduler.service.ts`
### 5.1 Overview
Uses `@nestjs/schedule` to run daily maintenance tasks. All times in UTC.
### 5.2 Cron Jobs
#### Job 1: Slot Generation
```
@Cron('0 2 * * *') // 02:00 UTC daily
async handleSlotGeneration()
```
- Calls: `slotGenerator.generateSlots(14)`
- Generates slots 14 days ahead
- Purpose: Keep pipeline filled
---
#### Job 2: Slot Cleanup
```
@Cron('30 2 * * *') // 02:30 UTC daily
async handleCleanupSlots()
```
- Calls: `slotGenerator.cleanupExpiredSlots()`
- Marks past OPEN slots as CLOSED
---
#### Job 3: Membership Check
```
@Cron('0 3 * * *') // 03:00 UTC daily
async handleCheckMemberships()
```
- Calls: `slotGenerator.checkExpiredMemberships()`
- Expires memberships by date or used-up sessions
---
#### Job 4: Booking Completion
```
@Cron('0 22 * * *') // 22:00 UTC daily
async handleCompleteBookings()
```
- Calls: `slotGenerator.completeBookings()`
- Marks past CONFIRMED bookings as COMPLETED
---
## 6. BookingService - Integration with TimeSlots
**Location:** `packages/server/src/booking/booking.service.ts`
### 6.1 Key Integration Points
#### `createBooking(userId: string, dto: CreateBookingDto): Promise<BookingWithRelations>`
**DTO:**
```typescript
class CreateBookingDto {
timeSlotId: string // UUID of TimeSlot
membershipId: string // UUID of Membership
}
```
**Transaction Flow:**
```
1. Fetch TimeSlot - validate status = OPEN
2. Check unique constraint - user not already booked this slot
3. Fetch Membership - validate:
- Belongs to user
- Status = ACTIVE
- Has remaining capacity:
* TIMES/TRIAL: remainingTimes > 0
* DURATION: not expired
4. Create Booking(userId, timeSlotId, membershipId) → CONFIRMED
5. Update TimeSlot:
- bookedCount++
- If bookedCount >= capacity, set status = FULL
6. Update Membership (if time-based):
- remainingTimes--
- If remainingTimes = 0, set status = USED_UP
7. Return booking with relations
```
**Error Handling:**
- TimeSlot not OPEN → BadRequestException
- Duplicate booking → ConflictException
- Invalid membership → ForbiddenException
- No remaining sessions → BadRequestException
---
#### `cancelBooking(userId: string, bookingId: string): Promise<CancelBookingResult>`
**Refund Logic:**
```
cancelHoursLimit = StudioConfig.cancelHoursLimit (default 2 hours)
slotStartMs = Date(date).setUTC Hours + startTime
deadlineMs = NOW + (cancelHoursLimit * 3600 * 1000)
withinLimit = slotStartMs >= deadlineMs
IF withinLimit:
Restore membership.remainingTimes++
ELSE:
No refund
```
**Transaction Flow:**
```
1. Mark Booking → CANCELLED, set cancelledAt
2. Decrement TimeSlot.bookedCount
3. If slot was FULL, restore to OPEN
4. If within cancel window:
- For TIMES/TRIAL: increment remainingTimes
- Restore membership status if was USED_UP
```
---
#### `getMyBookings(userId: string, status?, page, limit): Promise<PaginatedResult>`
Lists user's bookings with pagination, optionally filtered by status.
---
#### `getUpcomingBookings(userId: string): Promise<BookingWithRelations[]>`
Returns all CONFIRMED bookings for dates >= today, ordered by date.
---

## 11. Key Architectural Patterns
### 11.1 Idempotent Slot Generation
**Problem:** If scheduler crashes or delays, slots might not be generated.
**Solution:**
- Use `createMany(skipDuplicates: true)` with unique constraint on `[date, startTime, endTime]`
- Safe to re-run multiple times
- Only inserts new combinations
---
### 11.2 Atomic Transactions
**For Booking Creation:**
- Create booking, update slot, update membership in single transaction
- All-or-nothing: ensures consistency if any step fails
**For Cancellation:**
- Cancel booking, restore slot, conditionally restore membership
- Prevents race conditions
---
### 11.3 ISO Weekday Mapping
**Problem:** JavaScript `Date.getDay()` uses 0=Sunday, but WeekTemplate uses ISO 8601 (1=Monday).
**Solution:** Helper function `toIsoWeekday()`:
```typescript
function toIsoWeekday(jsDay: number): number {
return jsDay === 0 ? 7 : jsDay
}
```
---
### 11.4 Membership Type Handling
**TIMES/TRIAL cardType:**
- Deduct `remainingTimes--` on booking
- Mark USED_UP when remainingTimes = 0
- Refund if cancelled within window
**DURATION cardType:**
- Check `expireDate` not passed
- No deduction; just check validity
- No refund on cancellation
---
## 12. Example Scenarios
### Scenario 1: Setup Studio with Mon-Fri Classes
**Admin Actions:**
```json
PUT /admin/week-template
{
"templates": [
{ "dayOfWeek": 1, "startTime": "09:00", "endTime": "10:00", "capacity": 1 },
{ "dayOfWeek": 1, "startTime": "10:30", "endTime": "11:30", "capacity": 1 },
{ "dayOfWeek": 2, "startTime": "09:00", "endTime": "10:00", "capacity": 1 },
{ "dayOfWeek": 3, "startTime": "09:00", "endTime": "10:00", "capacity": 1 },
{ "dayOfWeek": 4, "startTime": "09:00", "endTime": "10:00", "capacity": 1 },
{ "dayOfWeek": 5, "startTime": "09:00", "endTime": "10:00", "capacity": 1 },
{ "dayOfWeek": 5, "startTime": "18:00", "endTime": "19:00", "capacity": 1 }
]
}
```
**Next Day (02:00 UTC):**
- Scheduler auto-generates 14 days of slots
- Result: 14 Mon morning + 14 Mon mid-morning + 14 Tue morning + ... + 14 Fri evening
**Member Action (View Availability):**
```
GET /time-slot/available?date=2026-04-10
→ Returns all slots for April 10 (Friday)
→ Includes bookings for current user
```
---
### Scenario 2: Member Books, Then Cancels
**Member Books:**
```
POST /booking
{
"timeSlotId": "slot-123",
"membershipId": "mem-456"
}
```
**System:**
1. Validates slot is OPEN, membership is ACTIVE with remaining sessions
2. Creates Booking(CONFIRMED)
3. Increments slot.bookedCount (1 → 2)
4. If now at capacity, sets slot.status = FULL
5. Decrements membership.remainingTimes (5 → 4)
**Member Cancels (within 2-hour window):**
```
PUT /booking/booking-789/cancel
```
**System:**
1. Checks if NOW + 2 hours ≤ slot start time ✓
2. Sets booking.status = CANCELLED
3. Decrements slot.bookedCount (2 → 1)
4. If slot was FULL, restores to OPEN
5. Increments membership.remainingTimes (4 → 5) ✓ refunded
---
### Scenario 3: Membership Expires
**Overnight at 03:00 UTC:**
- Scheduler runs `handleCheckMemberships()`
- Updates all ACTIVE memberships where `expireDate < NOW` to EXPIRED
- User tries to book → BadRequestException "Membership is not active (status: EXPIRED)"
---
## 13. Testing Guide
### Key Test Files
1. **`slot-generator.service.spec.ts`** (310 lines)
- Tests slot generation from templates
- Tests weekday mapping (JS vs ISO)
- Tests cleanup and expiration logic
- Tests membership and booking expiration
2. **`time-slot.service.spec.ts`** (existing)
- Tests getAvailableSlots with user booking status
- Tests manual slot creation
3. **`booking.service.spec.ts`** (existing)
- Tests booking creation with all validations
- Tests cancellation with refund logic
---
## 14. Configuration & Environment
### Required Env Variables
```
DATABASE_URL=mysql://...
```
### Studio Config (StudioConfig table)
- `cancelHoursLimit`: Hours before slot to allow free cancellation (default 2)
### Constants (shared package)
- `SLOT_GENERATION_DAYS`: 14 (days ahead to generate)
- `DEFAULT_SLOT_CAPACITY`: 1 (private lessons)
- `DEFAULT_CANCEL_HOURS_LIMIT`: 2
---
## 15. Performance Considerations
### Database Indexes
- `TimeSlot(date)` - for date range queries
- `TimeSlot(status)` - for status filtering
- `Booking(userId)` - for user's bookings
- `Booking(status)` - for status filtering
### Batch Operations
- Slot generation uses `createMany()` for efficiency
- Expiration checks use `updateMany()` instead of loops
### Transaction Isolation
- All booking/cancellation operations wrapped in transactions
- Prevents race conditions on bookedCount and remainingTimes
---
## 16. Security Notes
### Authorization
- JWT guard on all endpoints
- RolesGuard for admin endpoints (only ADMIN role)
- Users can only modify their own bookings/memberships
### Validation
- All DTOs have class-validator decorators
- UUID validation on foreign keys
- Date string validation (YYYY-MM-DD format)
### Data Integrity
- Unique constraint on `[userId, timeSlotId]` prevents duplicate bookings
- Unique constraint on `[date, startTime, endTime]` prevents duplicate slots
- Foreign key constraints on relations
---
## 17. Future Enhancement Ideas
1. **Overbooking Buffer:**
- Allow configurable overbooking ratio (e.g., 110% capacity)
2. **Waitlist Support:**
- Add BookingStatus.WAITLISTED
- Auto-promote when slot opens
3. **Recurring Cancellation:**
- Cancel all future bookings of a series
- Batch refunds
4. **Slot Availability Notifications:**
- Alert users when slots available
- Implement notification queue
5. **Dynamic Pricing:**
- Peak vs off-peak pricing
- Last-minute discounts
---
## Summary
This time-slot and scheduling system is well-architected with:
✅ **Idempotent slot generation** - Safe to re-run
✅ **Atomic transactions** - ACID compliance for bookings
✅ **Automatic maintenance** - 4 daily cron jobs
✅ **Flexible membership types** - TIMES, DURATION, TRIAL
✅ **Refund policy** - Configurable cancellation window
✅ **ISO weekday standard** - Proper international support
✅ **Comprehensive validation** - DTOs with decorators
✅ **Role-based access** - Admin vs member endpoints
The system handles:
- Auto-generating 14 days of slots nightly
- Accepting bookings with capacity management
- Canceling with conditional refunds
- Expiring memberships and marking past bookings
- All with transactional integrity and concurrent safety.
