我可以重新列出具有所有角色的所有用户的列表吗?我需要知道数据库中每个用户的所有角色。我在Kohana 3.3中使用Auth模块和ORM。
答案 0 :(得分:0)
是的,你可以。但我无法理解为什么你想做这样的事情不是最理想的。
<强> 1。完整的ORM:
$users = ORM::factory('Auth_User')->find_all();
foreach($users as $user) {
$roles = $user->roles->find_all();
foreach($roles as $role)
$role->name;
}
<强> 2。通用SQL (提示):
SELECT * FROM users
INNER JOIN user_roles USING(user_id)
INNER JOIN roles USING(role_id)
ORDER BY users.name
结果:
第3。轻松显示SQL (但每次添加新角色时都会更改代码)
SELECT users.*, IF(r1.user_id IS NULL, 0, 1) AS role1,
IF(r2.user_id IS NULL, 0, 1) AS role2,
IF(rn.user_id IS NULL, 0, 1) AS rolen
FROM users
LEFT JOIN (SELECT user_id FROM user_roles where role_id = 1) AS r1 USING(user_id)
LEFT JOIN (SELECT user_id FROM user_roles where role_id = 2) AS r2 USING(user_id)
LEFT JOIN (SELECT user_id FROM user_roles where role_id = n) AS rn USING(user_id)
结果:
username | role1 | role2 | rolen
user1 | 1 | 0 | 0
user2 | 0 | 1 | 1
