  沿着这些方向的东西应该与现有的信息一起使用：

  <?php
  class AppModel extends Model {
  
      public $lastErrorMessage;
  
      public function beforeSave(...) {
          $this->lastErrorMessage = null;
          return true;
      }
  
  }
  
  <?php
  class MyModel Extends AppModel {
  
      public function beforeSave(...) {
          parent::beforeSave(..);
          if (error) {
              $this->lastErrorMessage = 'Some error message';
              return false;
          }
          return true;
      }
  }
  
  <?php
  class MyController extends AppController {
  
      public function action() {
          if ($this->MyModel->save($this->request->data)) {
          } else {
              $message = "Some default message";
              if ($this->MyModel->lastErrorMessage) {
                  $message = $this->MyModel->lastErrorMessage;
              }
              $this->Session->setFlash($message);
          }
      }
  }
