传递给选择字段的实体必须进行管理 - 在app.php和app_dev.php上不同

欢迎！

我已在表单中添加了一个字段

    ->add('languageLevel', ChoiceType::class, [
        'choices' => [
            Meme::LEVEL_BEGINNER => Meme::LEVEL_BEGINNER,
            Meme::LEVEL_INTERMEDIATE => Meme::LEVEL_INTERMEDIATE,
            Meme::LEVEL_ADVANCED => Meme::LEVEL_ADVANCED,
            Meme::LEVEL_EXPERT => Meme::LEVEL_EXPERT
        ]
    ])

此表格可以保存实体＆Meme＆＃39;具有相同的属性

/**
 * @var string
 * @ORM\Column(name="language_level", type="string", length=20)
 */
private $languageLevel;

prod.log给了我这个：

在我的开发机器上的dev.log中，没有类似的东西，它工作正常。在prod上我得到错误500.请帮忙吗？我尝试删除供应商并在dev和prod服务器上再次安装它。使用--env = prod多次清除缓存。

修改

好的，在开发服务器上遇到了同样的问题（刚从apache配置中的app_dev.php切换到app.php并添加了app / autoload.php）

/**
 * @Route("/meme/add", name="meme_add")
 * @param Request $request
 * @return \Symfony\Component\HttpFoundation\Response
 * @internal param Request $request
 */
public function addAction(Request $request)
{
    $user = $this->getUser();
    if (!$user || !$user->hasRole('ROLE_MEME_ADD_AWAITING')) {
        $this->addFlash('notice', 'You need to login');
        return $this->redirectToRoute('fos_user_security_login');
    }

    if (!$this->get('security.authorization_checker')->isGranted('IS_AUTHENTICATED_FULLY')) {
        throw $this->createAccessDeniedException();
    }

    $meme = new Meme();
    $form = $this->createForm(MemeAddType::class, $meme);

    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid() ) {
        if ($user->hasRole('ROLE_MEME_ADD_AWAITING')) {
            $meme->setPublishingStatus('awaiting-publishing');
        } else if ($this->getUser()->hasRole('ROLE_MEME_ADD_MAIN')) {
            $meme->setPublishingStatus('published');
        }
        $em = $this->getDoctrine()->getManager();
        $em->persist($meme);
        $em->flush();
    }

    return $this->render(
        '@App/memes/add.html.twig',
        [
            'memeAddForm' => $form->createView()
        ]
    );
}

在formType

答案 1 :(得分：1)

实际上，发生的事情是我有

 'data' => 2

在textOneLang表单元素中，因此当它被赋予spl_object_hash（）函数时它失败了，它只接受对象而不是整数。没有使用数据转换器。但是这个'数据'参数不应该首先存在，不知道它是如何结束的。可能在尝试调试时。经验教训，找出所有选项，并将你在spl_object_hash（）中作为参数转储。

app_dev.php和app.php之间的区别与它没有任何关系。它可能在app_dev.php中以某种方式缓存并处理了一些旧版本。
