-- 清理题库 create_user_id 限制
|
||
-- 目的：让所有用户都能看到所有题库
|
||
-- ========================================
|
||
|
||
-- 说明：
|
||
-- 现在后端已修改为返回所有题库，不再按用户过滤
|
||
-- 但为了保证数据完整性，仍建议为题库设置 create_user_id
|
||
|
||

|
||
-- 第1步：检查题库数据状态
|
||

|
||
-- ========================================

||
-- 但为了数据完整性，建议仍然填充这个字段

-- ========================================
|
||
-- 完成！
|
||
-- ========================================
|
||
--
|
||
-- ✓ 后端已修改：/study/questionBank/my-banks 现在返回所有题库
|
||
-- ✓ 前端不需要修改：仍使用同一个接口
|
||
-- ✓ 现在所有用户都能看到所有题库
|
||
--
|
||
-- 注意：
|
||
-- 1. 需要重新编译后端（mvn clean package）
|
||
-- 2. 重启后端服务
|
||
-- 3. 刷新前端页面
|
||
-- 4. 进入考试管理 → 创建考试，应该能看到所有题库
