Symfony 6 AppEntityQuestion对象未被@ParamConverter注释找到

Question

我试着回答问题。

这是我的AnswerController:

#[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(),
]);
}

我有问题

AppEntityQuestion对象未被@ParamConverter注释找到

编辑:

我仍然对通配符有一点问题，例如，当我输入address "/audio -a3/8v/answer/question"没关系，但是当我输入"/audi-a/8v/answer/question"时;(没有8v型号的audi-a4，但这个地址给了我正确的"8v"页面;模型。不匹配)。有人能告诉我怎么做才对吗?

Answer 1

我在AnswerController中做了一些更改，现在它可以工作了。

手动设置参数转换器

#[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(),
]);
}
