Symfony 6 App \ Entity \问题对象未找到@ParamConverter注释

Question

我尝试提出问题的答案。

这是我的答案：

#[Route('/{slug}/{name}/answer/{question}', name: 'answer_question')]
public function answer(Question $q, QuestionRepository $questionRepository, string $question, Request $request, EntityManagerInterface $entityManager, string $slug, string $name, AnswerRepository $answerRepository): Response
{
    $questions = $questionRepository->findOneBySlug($question);

    $answers = $answerRepository->findAnswers($question);

    $form = $this->createForm(AnswerType::class);

    $form->handleRequest($request);
    if ($form->isSubmitted() && $form->isValid()) {
        $data = $form->getData();

        $answer = new Answer();
        $answer->setContent($data->getContent());
        $answer->setAnsweredAt(new \DateTime);
        $answer->setQuestion($q);

        $entityManager->persist($answer);
        $entityManager->flush();

        return $this->redirectToRoute('show_question', [
            'slug' => $slug,
            'name' => $name,
            'question' => $question,
        ]);
    }

    return $this->render('answer/index.html.twig', [
        'questions' => $questions,
        'answers' => $answers,
        'answer' =>  $form->createView(),
    ]);
}

我对

app \ entity \ Question对象

问题

的问题有 例如，当我放置地址“/audi-a3/8v/anders/ateys”时，这没关系，但是当我放置“/audi-a4/8v/wonse/ateys”时（没有Audi-a4与8V模型，但这地址为“ 8V”模型提供了正确的页面。 有人可以向我解释如何做正确吗？

Answer 1

我对AnswerController进行了一些更改，现在正在工作。

手动设置paramconverter。

#[Route('/{car}/{name}/answer/{slug}', name: 'answer_question')]
#[ParamConverter('question', class: Question::class, options: ['mapping' => ['slug' => 'slug']])]
public function answer(Question $question, QuestionRepository $questionRepository, Request $request, EntityManagerInterface $entityManager, string $slug, string $name, string $car, AnswerRepository $answerRepository): Response
{
    $questions = $questionRepository->findOneBySlug($slug);

    $answers = $answerRepository->findAnswers($slug);

    $form = $this->createForm(AnswerType::class);

    $form->handleRequest($request);
    if ($form->isSubmitted() && $form->isValid()) {
        $data = $form->getData();

        $answer = new Answer();
        $answer->setContent($data->getContent());
        $answer->setAnsweredAt(new \DateTime);
        $answer->setQuestion($question);

        $entityManager->persist($answer);
        $entityManager->flush();

        return $this->redirectToRoute('show_question', [
            'slug' => $slug,
            'name' => $name,
            'car' => $car,
        ]);
    }

    return $this->render('answer/index.html.twig', [
        'questions' => $questions,
        'answers' => $answers,
        'answer' =>  $form->createView(),
    ]);
}
