cakePHP-模型，不带约定/成员的控制器返回null

Question

I have a Problem with cakePHP.

This is my Model:

<?php
class Veranstaltung extends AppModel
{
    var $name = 'Veranstaltung';
    var $useTable = 'veranstaltungen';
}
?>

and this is my Controller:

<?php
class VeranstaltungenController extends AppController
{
    var $name = 'Veranstaltungen';
    public function index()
    {
        $this->set('veranstaltungen',$this->Veranstaltung->find('all'));
    }

}
?>

but $this->Veranstaltung Returns null.

How do I solve this?

Answer 1

You forget to include your model in controller. Do do this add $uses field in your controller which is type of array :

class VeranstaltungenController extends AppController
{
     public $uses = array('Veranstaltung');

     public function index()
     {
         $this->set('veranstaltungen',$this->Veranstaltung->find('all'));
     }
}

Documentation

If there still be a problem it could be required to use

App::uses('Veranstaltung', 'Model');

before your controller class definition.

And please forget about var keyboard, because it's only for backward compatibility with PHP4.

In order to maintain backward compatibility with PHP 4, PHP 5 will still accept the use of the keyword var in property declarations instead of (or in addition to) public , protected , or private . However, var is no longer required. In versions of PHP from 5.0 to 5.1.3, the use of var was considered deprecated and would issue an E_STRICT warning, but since PHP 5.1.3 it is no longer deprecated and does not issue the warning.

Answer 2

You don't need var $name = 'Veranstaltungen'; in your controller.

Also make sure you have configured your database properly?

Then try this:

$this->loadModel("Veranstaltungen");
$this->set('veranstaltungen',$this->Veranstaltung->find('all'));

Answer 3

 <?php
    class VeranstaltungenController extends AppController

    var $uses = array('Veranstaltungen');
    public function index()
    {
        $this->set('veranstaltungen',$this->Veranstaltung->find('all'));
    }
   } 
 ?>  

Try in your controller
