我有 3 张桌子;用户、组和权限
I have 3 tables; users, groups and permissions
在模型中,我将关系设置为belongsToMany在用户模型中:
In models I have the relationships set as belongsToMany in user model:
public function groups() {
return $this->belongsToMany('Group');
}
在组模型中:
public function users() {
return $this->belongsToMany('User');
}
public function permissions() {
return $this->belongsToMany('Permission');
}
在权限模型中:
public function groups() {
return $this->belongsToMany('Group', 'id');
}
许多用户 - 到 - 许多组许多组-对-许多权限
many users - to - many groups many groups - to - many permissions
我正在尝试获取用户拥有的所有权限,但不知道它的代码应该是什么样子.有人可以帮忙吗?
I'm trying to get all the permissions a user has, and have no clue what the code for it should look like. Can anyone help?
您可以这样做:
User::where('id', $id)->with(['groups.permissions' => function ($q) use (&$permissions) {
$permissions = $q->get()->unique();
}])->first();
// then
$permissions; // collection of unique permissions of the user with id = $id
