+-- 修复 category 表的 is_leaf 字段问题
+-- 问题：创建的类目 is_leaf 字段为 0，导致在发布任务时无法选择
+-- 解决：将类目设置为叶子节点（is_leaf = 1）
+-- 日期：2026-01-02
+
+USE designhub;
+
+-- 修复现有的类目数据，将它们设置为叶子节点
+UPDATE category 
+SET is_leaf = 1 
+WHERE deleted = 0 
+  AND is_leaf = 0;
+
+-- 验证修改结果
+SELECT 
+    id, 
+    category_name, 
+    parent_id,
+    level,
+    is_leaf, 
+    status,
+    create_time
+FROM 
+    category
+WHERE 
+    deleted = 0
+ORDER BY 
+    sort_order, id;
+
+-- 说明：
+-- 1. is_leaf = 1 表示叶子节点（最底层的类目，可以直接用于任务）
+-- 2. is_leaf = 0 表示父节点（有子类目的分类，不能直接用于任务）
+-- 3. 发布任务时只能选择叶子类目（is_leaf = 1 且 status = 1）
+-- 4. 如果您的类目需要分层级（如：家具 > 桌子 > 电脑桌），则：
+--    - 一级类目（家具）: is_leaf = 0, level = 1, parent_id = 0
+--    - 二级类目（桌子）: is_leaf = 0, level = 2, parent_id = 家具的id
+--    - 三级类目（电脑桌）: is_leaf = 1, level = 3, parent_id = 桌子的id
+-- 5. 如果您的类目不需要分层级，直接设置为叶子节点即可
