无法保存的Propel模型Symfony2的形式反对

Question

我想在Symfony2中与波轮编辑用户的角色。形式呈现精细，角色，用户目前已经被正确地检查。但保存新角色不起作用。我得到一个错误：Property role_id does not exist in class Acme\SecurityBundle\Model\User。

这是我的架构：

<?xml version="1.0" encoding="UTF-8"?> 
<database name="system" namespace="Acme\SecurityBundle\Model" defaultIdMethod="native"> 
    <table name="user"> 
     <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" /> 
     <column name="username" required="true" type="varchar" primaryKey="true" size="50" /> 
    </table> 

    <table name="role"> 
     <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" /> 
     <column name="role" required="true" type="varchar" size="20" primaryString="true" /> 
     <column name="name" required="true" type="varchar" size="50" /> 

     <unique> 
      <unique-column name="role" /> 
      <unique-column name="name" /> 
     </unique> 
    </table> 

    <table name="user_role" isCrossRef="true"> 
     <column name="user_id" type="integer" primaryKey="true"/> 
     <column name="role_id" type="integer" primaryKey="true"/> 
     <foreign-key foreignTable="user"> 
      <reference local="user_id" foreign="id"/> 
     </foreign-key> 
     <foreign-key foreignTable="role"> 
      <reference local="role_id" foreign="id"/> 
     </foreign-key> 
    </table> 
</database> 

我这是怎么呈现形式的控制器：

class UserManagementController extends Controller 
{ 
    public function indexAction(Request $request) 
    { 
     $user = UserQuery::create()->filterById(2)->findOne(); 
     $form = $this->createForm(new UserType($user), $user); 
     $form->handleRequest($request); 

     if ($form->isValid()) 
     { 
      $user->save(); 
     } 

     return $this->render('AcmeAdminBundle:UserManagement:index.html.twig', array(
      'form' => $form->createView() 
     )); 
    } 
} 

这是用户类型：

class UserType extends AbstractType 
{ 
    private $user; 

    public function __construct($user) 
    { 
     $this->user = $user; 
    } 

    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder 
      ->add('roles', 'model', array(
        'class' => 'Acme\SecurityBundle\Model\Role', 
        'multiple' => true, 
        'expanded' => true, 
        'property' => 'name', 
        'label' => $this->user->getUsername(), 

       ) 
      ) 
      ->add('save', 'submit'); 
    } 

    public function setDefaultOptions(OptionsResolverInterface $resolver) 
    { 
     $resolver->setDefaults(array(
       'data_class' => 'Acme\SecurityBundle\Model\User', 
      )); 
    } 


    public function getName() 
    { 
     return 'user'; 
    } 
} 

这个错误信息来自哪里？我该如何解决它？

Answer 1

多亏了PropelBundle community我终于想通了：这两个主键触发此错误。现在我只有一个主键，它的工作完美无瑕。
