# 食物库功能
|
||||
|
||||
## 功能概述
|
||||
|
||||
食物库功能提供了一个完整的食物数据库，包含各种食物的营养信息。用户可以通过分类浏览或搜索来查找食物。
|
||||
|
||||
## 数据库设计
|
||||
|
||||
### 食物分类表 (t_food_categories)
|
||||
- `key`: 分类唯一键（如：common, fruits_vegetables等）
|
||||
- `name`: 分类中文名称（如：常见、水果蔬菜等）
|
||||
- `icon`: 分类图标（可选）
|
||||
- `sort_order`: 排序顺序
|
||||
- `is_system`: 是否系统分类
|
||||
|
||||
### 食物库表 (t_food_library)
|
||||
- `id`: 食物唯一ID
|
||||
- `name`: 食物名称
|
||||
- `category_key`: 所属分类
|
||||
- `calories_per_100g`: 每100克热量
|
||||
- `protein_per_100g`: 每100克蛋白质含量
|
||||
- `carbohydrate_per_100g`: 每100克碳水化合物含量
|
||||
- `fat_per_100g`: 每100克脂肪含量
|
||||
- `fiber_per_100g`: 每100克膳食纤维含量
|
||||
- `sugar_per_100g`: 每100克糖分含量
|
||||
- `sodium_per_100g`: 每100克钠含量
|
||||
- `additional_nutrition`: 其他营养信息（JSON格式）
|
||||
- `is_common`: 是否常见食物
|
||||
- `image_url`: 食物图片URL
|
||||
- `sort_order`: 排序顺序
|
||||
|
||||
## 特殊逻辑
|
||||
|
||||
### 常见食物分类
|
||||
- 标记为 `is_common = true` 的食物会显示在"常见"分类中
|
||||
- 其他分类只显示 `is_common = false` 的食物
|
||||
- 这样避免了食物在多个分类中重复显示
|
||||
|
||||
## API接口
|
||||
|
||||
### 1. 获取食物库列表
|
||||
```
|
||||
GET /food-library
|
||||
```
|
||||
返回按分类组织的食物列表，常见食物会归类到"常见"分类中。
|
||||
|
||||
### 2. 搜索食物
|
||||
```
|
||||
GET /food-library/search?keyword=关键词
|
||||
```
|
||||
根据关键词搜索食物，常见食物会优先显示。
|
||||
|
||||
### 3. 获取食物详情
|
||||
```
|
||||
GET /food-library/:id
|
||||
```
|
||||
根据ID获取特定食物的详细信息。
|
||||
|
||||
## 数据初始化
|
||||
|
||||
1. 执行表结构创建脚本：
|
||||
```bash
|
||||
mysql -u root -p pilates_db < sql-scripts/food-library-tables-create.sql
|
||||
```
|
||||
|
||||
2. 插入示例数据：
|
||||
```bash
|
||||
mysql -u root -p pilates_db < sql-scripts/food-library-sample-data.sql
|
||||
```
|
||||
|
||||
## 客户端界面对应
|
||||
|
||||
根据提供的客户端界面，食物库包含以下分类：
|
||||
- 常见：显示标记为常见的食物
|
||||
- 水果蔬菜：fruits_vegetables 分类的非常见食物
|
||||
- 肉蛋奶：meat_eggs_dairy 分类的非常见食物
|
||||
- 豆类坚果：beans_nuts 分类的非常见食物
|
||||
- 零食饮料：snacks_drinks 分类的非常见食物
|
||||
- 主食：staple_food 分类的非常见食物
|
||||
- 菜肴：dishes 分类的非常见食物
|
||||
|
||||
每个食物显示：
|
||||
- 食物名称
|
||||
- 营养信息（如：139千卡/100克）
|
||||
- 添加按钮（+）
|
||||
|
||||
## 扩展功能
|
||||
|
||||
未来可以扩展的功能：
|
||||
- 用户自定义食物
|
||||
- 收藏食物功能
|
||||
- 食物图片上传
|
||||
- 营养成分详细分析
|
||||
- 食物推荐算法
