CakePHP保存空模型

我有2种类型的用户：employees和customers我需要区分它们，所以我为它们创建了2个单独的表。然后，我选择了CakePHP作为我的框架，然后我想遵循Simple Authentication教程，其中有一个用户表。所以我决定创建这样的表：CakePHP保存空模型

CREATE TABLE IF NOT EXISTS `users` (  
    `id` int(20) NOT NULL AUTO_INCREMENT, 
    `username` varchar(36) COLLATE utf8_czech_ci NOT NULL, 
    `password` varchar(36) COLLATE utf8_czech_ci NOT NULL, 
    `role` varchar(30) COLLATE utf8_czech_ci NOT NULL, 
    `name` varchar(30) COLLATE utf8_czech_ci NOT NULL, 
    `surname` varchar(40) COLLATE utf8_czech_ci NOT NULL, 
    `phone` varchar(16) COLLATE utf8_czech_ci NOT NULL, 
    `email` varchar(40) COLLATE utf8_czech_ci NOT NULL, 
    `employee_id` int(20) DEFAULT NULL, 
    `customer_id` int(20) DEFAULT NULL, 
    PRIMARY KEY (`id`), 
    UNIQUE KEY `EMAIL` (`email`) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_czech_ci AUTO_INCREMENT=1 ; 

CREATE TABLE IF NOT EXISTS `employee` (
    `id` int(20) NOT NULL AUTO_INCREMENT, 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB AUTO_INCREMENT=1 ; 

CREATE TABLE IF NOT EXISTS `customer` (
    `id` int(20) NOT NULL AUTO_INCREMENT, 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB DEFAULT AUTO_INCREMENT=1 ;

我的模型：

员工

public $hasOne = array(
     'User' => array(
      'className' => 'User', 
      'foreignKey' => 'employee_id', 
      'conditions' => '', 
      'fields' => '', 
      'order' => '' 
     ) 
    );

用户：

public $belongsTo = array(
      'Employee' => array(
       'className' => 'Employee', 
       'foreignKey' => 'employee_id', 
       'conditions' => '', 
       'fields' => '', 
       'order' => '' 
      );

添加用户功能：

public function add() { 
    if ($this->request->is('post')) {  
     $this->User->create();  
     $roles = array('admin', 'employee'); 
     if (in_array($this->request->data['User']['role'], $roles)) {             
     if ($this->User->Employee->save($this->request->data)) 
      $this->request->data['User']['employee_id'] = $this->User->Employee->getLastInsertId(); 
     else { 
      $this->Session->setFlash(__('Employee could not be saved.')); 
      return; 
     } 
     } 
     else { 
     $this->User->Customer->save($this->request->data); 
     $this->request->data['User']['customer_id'] = $this->User->Customer->getLastInsertId();   
     $this->User->Customer->create(); 

     }     
     if (!$this->User->save($this->request->data)) { 
     $this->Session->setFlash(__('The user could not be saved. Please, try again.')); 
     } 
     else {   
     $this->Session->setFlash(__('The user has been saved.')); 
     } 

     //return $this->redirect(array('action' => 'index'));   
    } 
    $employees = $this->User->Employee->find('list'); 
    $customers = $this->User->Customer->find('list'); 
    $this->set(compact('employees', 'customers')); 
}

我有一种感觉，这个概念模型是不正确的，因为Employee和Customer表只包含主键。

（$this->User->Employee->save($this->request->data）返回false。有没有CakePHP无法保存空模型的问题？

或者你有什么更好的想法如何建模这些表？

谢谢。

如果您打算获取特定于员工类型用户和客户类型用户的信息，那么您要进入的方向是否正常，并且您会将这些未来字段添加到客户和员工表中。如果您只需要区分员工类型用户和客户类型用户，那么您只需要在用户表中的一个字段中区分类型，如

is_employee tinyint(1) default 0,
