belongsTo cakephp关系不工作

我是cakephp的新手，我遵循了一些教程。现在我试图构建我的第一个应用程序，我被这个关系'belongsTo'卡住了。它没有正常工作，更有可能是我做错了什么。这是我的表，模型和控制器。

这个视图不显示任何人员id或名称。我都快疯了!!位于app/View/pending/add.ctp:

<div class='form'>
    <?php echo $this->Form->create('Pending'); ?>
        <fieldset>
            <legend>Nueva Tarea</legend>
                <?php
                    echo $this->Form->input('subject', array('label' => 'Asunto'));
                    echo $this->Form->input('body', array('label' => 'Descripcion', 'rows' => '3'));
                    echo $this->Form->input('staff_id', array('label' => 'Asignar a miembro'));
                ?>
        </fieldset>
    <?php echo $this->Form->end('Asignar'); ?>
</div>  

其中staff_id是此模型Pending的外键。和对应于staff表中的id。我尝试做的是Staff hasMany Pending和Pending belongsTo Staff。因为Pending是一种待定任务。这就是为什么staff有很多未决事项。

这是挂起模型，在app/model/Pending.php中使用'belongsTo'关系:

<?php
class Pending extends AppModel {
    public $validate = array(
        'subject' => array(
            'rule' => 'notEmpty', 
            'message' => 'Debe ingresar un Asunto.'
        ),
        'body' => array(
            'rule' => 'notEmpty', 
            'message' => 'Debe ingresar una Descripción.'
        )
    );
    public $belongsTo = array(  
            'Staff' => array(
                    'className' => 'Staff',
                    'foreignKey' => 'staff_id'
                    )           
            ); 
}
?>

这是Staff模型，在app/model/Staff.php中使用'hasMany'关系:

<?php
class Staff extends AppModel {
    public $displayField = 'name';
    public $validate = array(
        'last_name' => array(
            'rule' => 'notEmpty'
        ),
        'name' => array(
            'rule' => 'notEmpty'
        ),
        'passwd' => array(
            'rule' => 'notEmpty'
        ),
        'email' => array(
        'rule' => 'notEmpty'
        )
    );
    public $hasMany = array( 
                    'Pending' => array( 
                        'className' => 'Pending',
                        'foreignKey' => 'staff_id'
                        )
                    );
}
?>

最后是我的两张桌子，员工和待定的

我想我遵循了cakephp的约定。我真的看不出我的错误。谢谢你的帮助。

对不起，这里是控制器(app/controller/PendingsController.php):

<?php
class PendingsController extends AppController{
    public function index(){
        $this->Pending->recursive = 0;
        $this->set('pendings', $this->paginate());
    }
    public function add(){
        if( $this->request->is('post') )
        {
            if( $this->Pending->save($this->request->data) )
            {
                $this->Session->setFlash('Tarea Asignada');
                $this->redirect(array('action' => 'index'));
            }
        }
        $staffs = $this->Pending->Staff->find('list');
    }
}
?>
