我对实体有问题。 目标是显示一个表单，用户可以使用该表单更改其个人信息，例如Email或password。我为此创建了一个表单，但是当我创建/Edit路由时，出现以下错误：
"@ParamConverter批注找不到应用程序\实体\用户对象。">
这是我的控制器：
<?php
namespace AppController;
use AppEntityUsers;
use AppFormEditProfileType;
use AppFormUsersType;
use AppRepositoryUsersRepository;
use SymfonyBundleFrameworkBundleControllerAbstractController;
use SymfonyComponentHttpFoundationRequest;
use SymfonyComponentHttpFoundationResponse;
use SymfonyComponentRoutingAnnotationRoute;
/**
* @Route("/users")
*/
class UsersController extends AbstractController
{
/**
* @Route("/", name="users_index", methods={"GET"})
*/
public function index(): Response
{
return $this->render('users/index.html.twig');
}
/**
* @Route("/{id}", name="users_show", methods={"GET"})
*/
public function show(Users $user): Response
{
return $this->render('users/show.html.twig', [
'user' => $user,
]);
}
/**
* @Route("/edit", name="users_edit")
*/
public function editProfile(Request $request): Response
{
$user = $this->getUser();
$form = $this->createForm(EditProfileType::class, $user);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush();
$this->addflash('message', 'Profile mis à jour');
return $this->redirectToRoute('users');
}
return $this->render('users/editprofile.html.twig', [
'form' => $form->createView(),
]);
}
这是表格：
<?php
namespace AppForm;
use AppEntityUsers;
use SymfonyComponentFormAbstractType;
use SymfonyComponentFormExtensionCoreTypeSubmitType;
use SymfonyComponentFormFormBuilderInterface;
use SymfonyComponentOptionsResolverOptionsResolver;
class EditProfileType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('email')
->add('pseudo', TextType::class)
->add('Valider', SubmitType::class)
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Users::class,
]);
}
}
下面是实体用户：

以下是View Editprofile.html.twig：
{% extends 'basefront.html.twig' %}
{% block title %} Profile de {{ app.user.pseudo }} {% endblock %}
{% block body %}
<h1 class="h1 text-center">Modification du profile de {{ app.user.pseudo }}</h1>
{{ form(form) }}
{% endblock %}
顺序很重要。 尤其是在没有要求的情况下进行路由时。 您有以下路由(更新：添加了前缀，谢谢@Cerad！
/users/ users_index
/users/{id} users_show
/users/edit users_edit
现在，当您请求 URI/users/edit时，UrlMatcher 将遍历您的路由以查看是否匹配以及哪些匹配，并在第一个匹配时停止。
/users/显然不匹配/users/{id}确实匹配，因为{id}允许是任何字母数字字符串(+一些额外的字符(，并且edit匹配，导致users_show路由，User对象不能由 id "edit" 确定。因此，出现错误消息。解决此问题的一种方法是向路由匹配添加要求 - 假设 id 仅为数字：
/**
* @Route("/{id}", ..., requirements={"id":"d+"})
*/
我也同意@Cerad的观点，即Users对一个实体来说是一个非常糟糕的名字。它们通常采用单数形式。
