CakePHP的显示第二模型关联名，而不是ID

Question

我在数据库中的下一个表：

• 电梯
• 车辆
• 厂商

电梯属于关联车辆

车辆belongsTo制造商

制造商的hasMany车辆

LiftsController.php添加方法：

public function add() { 
    if ($this->request->is('post')) { 
     $this->Lift->create(); 
     $this->request->data['Lift']['user_id'] = $this->Auth->user('id'); 
     if ($this->Lift->save($this->request->data)) { 
      $this->Session->setFlash(__('The lift has been saved')); 
      $this->redirect(array('action' => 'my_lifts')); 
     } else { 
      $this->Session->setFlash(__('The lift could not be saved. Please, try again.')); 
     } 
    } 
    $vehicles = $this->Lift->Vehicle->find('all', array('fields' => array('id', 'model', 'manufacturer_id'))); 
    $towns = $this->Lift->TownFrom->find('list', array('order' => 'county ASC, name ASC', 'fields' => array('id', 'name', 'county'))); 
    $this->set(compact('users', 'vehicles', 'towns')); 
} 

LiftsController.php添加视图：

echo $this->Form->input('vehicle_id'); 

甲PRINTSCREEN：

所以我需要的是显示，而不是制造商ID的制造商名称。 在每一个模型$ displayField被设置为正确的值

Answer 1

变化

$vehicles = $this->Lift->Vehicle->find('all', array('fields' => array('id', 'model', 'manufacturer_id'))); 

为

$vehicles = $this->Lift->Vehicle->find('list', array('conditions' => array('Vehicle.user_id' => $this->Auth->user('id')), 'recursive' => 0, 'fields' => array('Vehicle.id', 'Vehicle.model', 'Manufacturer.title'))); 

Answer 2

尝试改变：

echo $this->Form->input('vehicle_id'); 

要

echo $this->Form->input('Vehicle');
