无法使用cakephp

Question

在执行add方法后的数据库中我只检索外键tarid_id，其他字段为空这里是我的Adherent Model的代码：谢谢你的回答

         <?php
           App::uses('AppModel', 'Model');
              /**

  */
   class Adherant extends AppModel {

       /**

    ),

    ),
);

       //The Associations below have been created with all possible keys,   those   that are not needed can be removed

    public $belongsTo = array(

}

我的add方法：

    public function add() {



    $this->loadModel('User');
    $this->loadModel('Tarif');
     //$tarif_id=this->Session->read('tarif_id');

    $this->Session->write('Person.addAdh',"");
    if ($this->request->is('post')) {


$this->Adherant->create();
        $login=$this->request->data['login'];
        $pass=$this->request->data['motpass'];
          $count=$this->User-          >find('count',array('conditions'=>array('User.login'=>$login)));
if($count==1){
$this->redirect(array('action' => 'add'));
$this->Session->write('Person.addAdh',"adherant existe déjà (user)");

 }else{
         $count1=$this->Adherant-   >find('count',array('conditions'=>array('Adherant.cin'=>$this->request-    >data['cin'])));
         if($count1==0){
     $this->User->save( 
            array(
                'login' => $login,
                'motpass' => $pass,

                )
            );
$first=$this->User- >find('first',array('conditions'=>array('User.login'=>$login)));
         $user=$first['User']['id'];
         if ($this->Adherant->saveAll($this->request->data, array('deep' =>   true)))
 {


       $this->Session->setFlash( __('The ADHERANT has been saved'),  'success');
              return $this->redirect(array('action' => 'index'));
          }
        }else{
        $this->redirect(array('action' => 'add'));
    $this->Session->write('Person.addAdh',"adherant existe déjà(cin)");
    }

   }}



        $users = $this->Adherant->User->find('list');

      $tarifs = $this->Adherant->Tarif-       >find('list',array('fields'=>array('Tarif.id','Tarif.designation')));
        $this->set(compact('users','tarifs'));
