+# 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。

+
+| 字段名 | 类型 | 描述 | 备注 |
+| :--- | :--- | :--- | :--- |

+### 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` 了 `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` 和 `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` 或 `is_hot` 为 `true`。
+
+4.  **Supabase 安全策略 (RLS)**:
+    *   请确保商家端账号有权限写入 `ml_products` 和 `ml_shops` 表，但只能修改 `merchant_id` 等于自己账号的数据。
