# 消费者端前端数据库文档 (Consumer App DB Schema)
本文档基于现有消费者前端 (`mall/pages/mall/consumer`) 和 Supabase 服务层 (`mall/utils/supabaseService.uts`) 的调用逻辑生成。旨在协助商家端前端开发进行数据库对接。

## 2. 商品系统 (Product System)
### 2.1 商品主表 (`ml_products`)
商家发布的核心商品数据。

### 2.2 商品 SKU 表 (`ml_product_skus`)
商品的多规格定义(如颜色、尺寸)。

| `stock` | Integer | 当前库存 | |
| `image_url` | Text | 规格对应图片 | 如红色款对应红色的图 |
| `status` | Integer | 状态 | 1: 启用, 0: 禁用 |
### 2.3 商品详情视图 (`ml_products_detail_view`)
**重要**: 消费者端主要通过此视图查询商品,商家在维护数据时应确保这些关联字段能正确生成。
* 该视图通常 `JOIN``ml_shops` (获取 `shop_name`), `ml_brands` (获取 `brand_name`), `ml_categories` (获取 `category_name`)。
* **商家端操作**: 不需要直接操作视图,只需维护上述基础表。

## 5. 对接建议 (Integration Tips for Merchant Frontend)
1. **商品管理**:
* 在创建商品时,必须先选择 `category_id``merchant_id`
* 如果有 `specifications` (多规格),请同时向 `ml_product_skus` 插入数据。
* 更新库存时,请优先更新 `ml_product_skus` 中的 `stock`,并同步总库存到 `ml_products`.`total_stock`
2. **图片处理**:
* 消费者端支持 `main_image_url` (字符串) 和 `image_urls` (JSON 数组) 两种格式,请确保都正确填充。
3. **状态管理**:
* 上架商品请将 `status` 设为 `1`
* 如需在首页 "推荐/热销" 板块显示,请设置 `is_featured``is_hot``true`
4. **Supabase 安全策略 (RLS)**:
* 请确保商家端账号有权限写入 `ml_products``ml_shops` 表,但只能修改 `merchant_id` 等于自己账号的数据。
