Question

我正在用Symfony 4.1开发我的第一个项目。我在Twig中用于呈现表单的控制器中的函数中的redirectToRoute存在问题。函数正确，但是提交表单后出现错误：渲染模板时引发了异常（“渲染“ http://localhost:8000/pl/contact/agro/时出错”（状态代码为302）。在哪里可以找到解决方案问题吗？也许没有路由头就无法在此操作中使用redirectToRoute函数吗？

我的ContactController

class ContactController extends Controller
{
    public function renderForm(Request $request, $currentBrand)
    {
        $formData = new ContactEmail();

    $form = $this->createForm(ContactFormType::class, $formData);
    $formSecond = $this->createForm(ContactFormType::class, $formData);

    $form->handleRequest($request);
    $formSecond->handleRequest($request);

    $sendFlag = false;
    $sendFlagSecond = false;

    if ($form->isSubmitted() && $form->isValid()) {
        $formData = $form->getData();
        $formData->setIpAddress($request->getClientIp());

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

        return $this->redirectToRoute('main_page_contact', [
            'slugBrand' => $currentBrand->getSlugName(),
        ]);

    } else if ($formSecond->isSubmitted() && $formSecond->isValid()) {
        $formData = $formSecond->getData();
        $formData->setIpAddress($request->getClientIp());

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

        return $this->redirectToRoute('main_page_contact', [
            'slugBrand' => $currentBrand->getSlugName(),
        ]);
    }


        return $this->render('main_page/widget/contact/contact-form.html.twig', [
            'form' => $form->createView(),
            'formSecond' => $formSecond->createView(),
            'wasSent' => $sendFlag,
            'wasSentSecond' => $sendFlagSecond,
        ]);
    }
}

表单是通过Twig的以下代码呈现的：

render（controller（'App \ Controller \ MainPage \ ContactController :: renderForm'，{'request'：app.request，'currentBrand'：currentBrand}））}}

感谢答案！

我有解决办法。 RedirectToRoute应该使用与@Route相同的方法，由redirectToRoute调用。看起来一切都可行。

/**
* @Route("/{_locale}/contact/{slugBrand}/", name="main_page_contact")
*/
class ContactController extends Controller
{
    public function index(Request $request, $slugBrand)
    {
        $currentBrand = $this->getDoctrine()
            ->getRepository(Brand::class)
            ->getOneOrNullVisibleBySlugName($slugBrand);

    if (is_null($currentBrand)) {
        return new Response('Brak marki');
    }

    $formData = new ContactEmail();

    $form = $this->createForm(ContactFormType::class, $formData);
    $formSecond = $this->createForm(ContactFormType::class, $formData);

    $form->handleRequest($request);
    $formSecond->handleRequest($request);

    $sendFlag = false;
    $sendFlagSecond = false;

    if ($form->isSubmitted() && $form->isValid()) {
            $formData = $form->getData();
            $formData->setIpAddress($request->getClientIp());

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

            return $this->redirectToRoute('main_page_contact', [
            'slugBrand' => $currentBrand->getSlugName()]);

        } else if ($formSecond->isSubmitted() && $formSecond->isValid()) {
            $formData = $formSecond->getData();
            $formData->setIpAddress($request->getClientIp());

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

            return $this->redirectToRoute('main_page_contact', [
            'slugBrand' => $currentBrand->getSlugName()]);
    }
    return $this->render('main_page/widget/contact/contact-form.html.twig', [
        'form' => $form->createView(),
        'formSecond' => $formSecond->createView(),
        'wasSent' => $sendFlag,
        'wasSentSecond' => $sendFlagSecond,
        'currentBrand' => $currentBrand,
        'slugBrand' => $slugBrand,
        'shared' => $this->getAllSharedDataForLayout(),
    ]);
}

RedirectToRoute和状态码302
