kohana - How to delete all user roles in Kohana 3

Question

I'm using ORM Auth module and it's difficult to figure out how to do it. I've tried this case:

$user = ORM::factory('user', $id);
$user->roles->delete_all();

And got error ErrorException [ Fatal Error ]: Call to undefined method Database_Query_Builder_Delete::join()

However $user->roles->find_all(); gives me exactly what i want.

Answer 1

根据 Kohana_ORM 类的 3.1.3.1 版本代码，ORM 方法“remove($alias, $far_keys=NULL)”如果不传递第二个参数，则会销毁所有相关条目。

$user->remove('roles');

Answer 2

您不想从数据库中删除角色，而是删除用户模型和角色模型之间的关系。您可以使用ORM remove() 方法。

foreach ($user->roles->find_all() as $role)
{
    $user->remove('roles', $role);
}

Answer 3

只需为此功能创建一张票。您可以使用建议的代码。
