我从来没有使用过cakephp之前，我们有一个项目，为我们的客户编辑cakephp 2.5。
我们试图创建一个新的功能“Employis”来添加网站内的工作。我们主要是从网站内已经工作的其他模型/控制器重新创建现有的功能，但目前我们得到了这个错误，我们无法找出问题所在。

Error: Call to a member function disable() on a non-object
File: /home/voyou/subdomains/labsurface/app/Controller/EmploisController.php
Line: 95

模型如下：/app/Model/Emploi.php

<?php
App::uses('AppModel', 'Model');
/**
 * Emploi Model
 *
 */
class Emploi extends AppModel {

public $faIcone = "thumb-tack";
public $order = 'Emploi.ordre';

public $actsAs = array(
        'I18n' => array(
            'fields' => array('nom')
        ),
    );
/**
 * Display field
 *
 * @var string
 */
    public $displayField = 'nom_fre';
/**
 * Search field
 *
 * @var string
 */
    public $searchField = 'nom_fre';
}

这是控制器：/app/Controller/EmploisController.php

<?php
App::uses('AppController', 'Controller');
/**

 */
class EmploisController extends AppController {

        }
    }

        }

                }
            }
        }
    }
}

错误点指向public function admin内的$this->Emploi->Behaviors->disable('I18n');行，但根据我们的理解，$this->Emploi为空，我们不知道如何将模型链接到控制器。
