Symfony 2 学说一对多关系映射难倒

Question

我收到一个错误“错误：调用未定义的方法 Login\LogBundle\Entity\User::getToken()” 当尝试从另一个实体 apiuserdetails 获取数据时。 user_id 是 apiuserdetails 中的外键。我一直在关注示例http://symfony.com/doc/current/book/doctrine.html 关系映射模型。我可以使用 getRepository("LoginLogBundle:UserApiProfile") 从用户实体获取信息，但是如果按照他们的描述反向执行，我会收到错误消息。我在映射上做错了，但看不到它。将不胜感激一些帮助谢谢。

控制器代码是

     namespace Login\LogBundle\Controller;
     use Symfony\Bundle\FrameworkBundle\Controller\Controller;
     use Symfony\Component\HttpFoundation\Request;
     use Login\LogBundle\Entity\User;
     use Login\LogBundle\Entity\UserApiDetails;
     use Symfony\Component\Validator\Validation;
     use Symfony\Component\Validator\Constraints as Assert;

    class DefaultController extends Controller
    {

     public function userprofileAction(Request $request) {



     if ($request->getMethod()=='POST') {

    $name=$request->get('name');

    $em = $this->getDoctrine()->getManager();

    $repository = $em->getRepository("LoginLogBundle:User");

    $user = $repository->findOneBy(array('username'=>$name));


    return $this->render('LoginLogBundle:Default:userprofile.html.twig',array('token'  => $user->getToken()));        

    }
    }

    else {
       return $this->render('LoginLogBundle:Default:userprofile.html.twig');  
    }


 }

}

Answer 1

如果您收到 \Login\LogBundle\Entity\User，则您没有 setToken 并在错误消息中说明。而且，由于您没有\Login\LogBundle\Entity\UserApiDetails 的导航属性，事实上，如果您朝这个方向前进，您就会被卡住。要么您拥有来自User 的导航属性，以获取（单个或列表）UserApiDetails，或者您获取UserApiDetails 并使用导航属性来获取User 信息。在最后一种情况下，您可以简单地在树枝中使用{{ userapi.user.token }}
