在CakePHP中，我将在哪里对会话用户执行检查的方法？

问题描述

背景：我有一个方法 levelCheck（），它将当前用户的级别与几个参数进行比较，并返回true或false。我需要能够从任何控制器访问此方法，我也想调用它在帮助程序中用于菜单等。

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.

问题：由于Cake的灵活性，我几乎可以从任何地方调用Cake。哪里是正确的地方放这个？在自定义会话（扩展）？在AppController中？一个新的组件处理当前用户？在用户模型或用户控制器？

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?

这里的重要一点是我（或其他人）将来如何确定这样的事情的正确位置？

The important piece here is how would I (or others) determine the correct location for such a thing in the future?

推荐答案

将此方法放在AppController中

Put this method in AppController

class AppController extends Controller
{

  function levelCheck(){
    # whatever
  }

}

这是此操作的正确位置。因为AppController在所有控制器中扩展，所以这个方法可以使用当前控制器对象$ this-> levelCheck（）来调用。

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().
