我有 3 个实体：用户、用户角色、用户配置文件。我的用户配置文件实体的主键实际上是来自用户实体的外键，即 UserId。 每次我尝试使用外键用户 ID 访问 userProfile 时。我总是收到未定义用户 ID 索引的错误。

这是确切的错误信息

public function profileAction($id)

        $user = new User();
        $user_repository = $this->getDoctrine()->getRepository('AcmePodUserBundle:User');
        $user = $user_repository->find($id);

        $userprofile = new UserProfile();
        $userprofile_repository = $this->getDoctrine()->getRepository('AcmeUserBundle:UserProfile');       
        $userprofile = $userprofile_repository->find($user);

       return new Response($userprofile); // this is not the actual output i need. I just used this simply to test if userprofile has some value.

我认为问题出在我的控制器代码上。有人可以告诉我编码的正确方法吗？PS 我将用户与用户个人资料分开，因为我不想在表格中将用户帐户数据（如用户名、角色等）与其用户信息混为一谈。
