在CakePHP中，我将在哪里放置一个对会话用户执行检查的方法？
Background: I have a method levelCheck() which compares the current user's level to a few parameters, and returns a true or false. I need to be able to access this method from any controller, and I would also like to put a call to it inside a helper for use on menus, etc.
Question: Due to Cake's flexibility, I can call almost anything from almost anywhere with Cake. Where is the correct place to put this? In a custom Session (extended)? In the AppController? A new component dealing with the current user? In the UserModel or User Controller?
The important piece here is how would I (or others) determine the correct location for such a thing in the future?

Put this method in AppController
class AppController extends Controller
{
function levelCheck(){
# whatever
}
}
This is the correct place of this action. Because AppController is extended in all the controller so this method can called using current controller object that is $this->levelCheck().
On AppController
function beforeFilter()
{
$this->custome_componnetst_name->levelCheck(parameters.....);
/*action*/
}
