+-- 测试当前用户class_id功能的验证脚本
+
+-- 1. 检查ak_users表中用户的class_id设置情况
+SELECT 
+    id,
+    username,
+    email,
+    role,
+    school_id,
+    grade_id,
+    class_id
+FROM public.ak_users 
+WHERE role IN ('teacher', 'student')
+ORDER BY role, username;
+
+-- 2. 检查每个班级的学生分布
+SELECT 
+    c.id as class_id,
+    c.name as class_name,
+    g.name as grade_name,
+    s.name as school_name,
+    COUNT(u.id) as student_count,
+    array_agg(u.username) as student_names

+-- 3. 检查是否有用户（老师或学生）分配到了同一个班级
+SELECT

+-- 这里以第一个有class_id的用户为例

+-- 如果视图不存在，这个查询会报错
