Question

我收到错误'错误：调用未定义的方法Login \ LogBundle \ Entity \ User :: getToken（）' 当试图从另一个实体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。我能够使用getRepository（“LoginLogBundle：UserApiProfile”）从用户实体获取信息，但如果按照他们的描述反向执行，我会得到错误。我在做映射时出错了但看不到它。非常感谢一些帮助谢谢。

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，则表示您没有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，实际上，如果您朝着这个方向前进，那就会卡住。您可以使用User中的导航属性，获取（单个或列表）UserApiDetails，也可以使用UserApiDetails并使用导航属性获取User信息。在最后一种情况下，您只需在树枝{{ userapi.user.token }}

中使用即可
