title: Calling a method from AppModel class from its child or Controller
body: <p>Hello this is my AppModel.php Class</p>
  
  <pre><code>&lt;?php
  App::uses('Model', 'Model');
  class AppModel extends Model{
  
  
      static public function message()
      {
          return 'this is a message';
      }
  
  }
  </code></pre>
  
  <p>and I have my model User.php</p>
  
  <pre><code>&lt;? 
  class User extends AppModel {
  
  }
  </code></pre>
  
  <p>and my controller UsersController.php</p>
  
  <p>
  
  <pre><code>class UsersController extends AppController
  {
   public function index()
      {
          $this-&gt;layout ='main';
  }
  
  }
  </code></pre>
  
  <p>My question is, how can I call method message() from its AppModel Class in UsersController or at least in my model Users?</p>
