Answer 1

嗨請提供代碼

正如你說，一個model是節省，但有些則沒有。這可能是model中定義的rules的問題。

嘗試getErrors()如果模型沒有保存

$vm = (object) array(); 
    $vm->Users=new Users; 
    $vm->Student=new Student; 
    $vm->Instructor=new Instructor; 
    $holder; 

    // $model=new Users; 
    // Uncomment the following line if AJAX validation is needed 
    // $this->performAjaxValidation($model); 

    if(isset($_POST['Users'])) 
    { 
     $vm->Users->attributes=$_POST['Users']; 
     $vm->Users->save(); 
      if(isset($_POST['Student'])) 
       { 
       $vm->Student->attributes=$_POST['Student']; 
       $vm->Student->studentid = $vm->Users->username; 
        if($vm->Student->save()) 
         $vm->Student->unsetAttributes(); 
         else{ 
          print_r($vm->Student->getErrors());die;// to get errors 
          } 

       } 
      if(isset($_POST['Instructor'])) 
       { 
       $vm->Instructor->attributes=$_POST['Instructor']; 
       $vm->Instructor->instructorid = $vm->Users->username; 
        if($vm->Instructor->save()) 
         $vm->Instructor->unsetAttributes(); 
        else{ 
          print_r($vm->Instructor->getErrors());die;// to get errors 
          } 
       } 
      else { 
       return false; 
       } 
    } 

      // echo 'saved'; 
      // $this->redirect(array('view','id'=>$model->username)); 

    $vm->Users->unsetAttributes(); 
    $vm->Student->unsetAttributes(); 
    $vm->Instructor->unsetAttributes(); 
    $this->render('users',array(
     'vm'=>$vm, 
    )); 
} 

Answer 2

爲了調試，還記得你可以添加：

if($vm->Student->save()) { 
    $vm->Student->unsetAttributes(); 
} else { 
    var_dump($vm->getErrors()); 
    die; 
} 

同爲教師。希望它有幫助
