Symfony 外键（我如何编辑它们？）

Question

我有一个小问题，我不知道为什么我不能编辑我的外键（$idProfile），但我可以编辑数据库中的其他值：

我可以更改值 enable 例如但不能更改 idProfile 当我尝试更改它时出现此错误："An instance of Symfony\Bundle\FrameworkBundle\Templating\EngineInterface must be injected in FOS\RestBundle\View\ViewHandler to render templates." 不知道这是否可以帮助 thx 寻求帮助：p

总的来说：我只想知道如何使用我的个人资料实体

将我的 $id_profile 编辑为 link

我的配置文件控制器：

 /**
 * Creates a new profile entity.
 *
 * @Route("/new/{id}", name="profile_new")
 */
public function newProfileAction(Request $request, User $user)
{

    $loggedAs = $this->getUser();
    $username =  $loggedAs->getUsername();

    $profile = new Profile();
    $form = $this->createForm(ProfileType::class, $profile);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        $profile->setLastConnexion(new \DateTime('now'));
        $profile->setCreatedAccount(new \DateTime('now'));

        $em = $this->getDoctrine()->getManager();
        $em->persist($profile);
        $em->flush();

        $user->setEnabled('1');
        $user->setIdLocation($profile->getId());
        $em = $this->getDoctrine()->getManager();
        $em->persist($user);
        $em->flush();



        return $this->redirectToRoute('user_list');
    }

    return $this->render('admin/user/new_profile.html.twig', array(
        'profile' => $profile,
        'form' => $form->createView(),
        'username' => $username,
    ));
}

Answer 1

您将配置文件定义为 \AppBundle\Entity\Profile 的类型，这是使用学说的正确方法。不了解您的实体和数据库有什么区别...... 在实体中，您需要设置实体而不是 id。然后，Doctrine 会将 id 传递到数据库中，当您从 doctrine 获取实体时，它会将 id 解析为一个实体。这意味着：

 $user->setIdLocation($profile); //<-- set the entity
$profil =  $user->getIdLocation(); // get the profile not the id
