cakephp override construct in child controller

I'm wondering if it is possible to inherit/override constructors in child controllers in cakephp.

In my AppController.php

I have it like this:

public function __construct( $request = null, $response = null ) {
    parent::__construct( $request, $response );

    $this->email = new CakeEmail();

    $this->_constants = array();
    $this->_constants['some_var'] = $this->Model->find( 'list', array(
        'fields' => array( 'Model.name', 'Model.id' )
    ) );
}

and in my child controller SomeController.php, it inherits the parent constructor

public function __construct( $request = null, $response = null ) {
    parent::__construct( $request, $response );
}

and when I tried to access $this->email and $this->_constants['some_var'] they both are null. But as soon as I put the code directly in SomeController.php instead of inheriting, it worked.

Did I do something wrong or this is simply not approachable for cake? Also I tried the same with function beforeFilter(), same thing happened. But it makes sense that each controller to have its own beforeFilter().

I wouldn't even try overriding the _construct' function of the appController. That's what thebeforeFilter,beforeRender` methods are for. It looks like you are just trying to pass vars to each controller from the appController. You can do that like so...

class AppController extends Controller {

   var $_constants = array();

   public function beforeFilter(){
      $this->_constants[] = array('this', 'that', 'the other');
   }

}

and in your model's controller you can access the variable like so...

class UsersController extends AppController {

   public function add(){
      pr($this->_constants);
   }
}

It's a different story if you are trying to send the variables to the view (slightly). Just use the set method

class AppController extends Controller {

   public function beforeFilter(){
      $this->set('_constants', array('this', 'that', 'the other'));
   }

}

and in any view you can just call the _constants variable with pr($_constants);. Because it is in the appController it should be available on every view.
