我有一种将值写入特定实体的表单,并且我试图通过控制器中的函数来编辑信息,非常简单。
BancoController.php
<?php
namespace App\Controller;
use App\Entity\Banco;
use App\Form\BancoType;
use App\Repository\BancoRepository;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\Form\FormFactoryInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Session\Flash\FlashBagInterface;
use Symfony\Component\HttpFoundation\Session\SessionInterface;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Routing\RouterInterface;
use Symfony\Component\Security\Core\Authorization\AuthorizationCheckerInterface;
use Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Security;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
class BancoController{
private $twig;
private $bancoRepository;
private $formFactory;
private $entityManager;
private $router;
private $flashBag;
private $authorizationChecker;
public function __construct(
\Twig_Environment $twig,
BancoRepository $bancoRepository,
FormFactoryInterface $formFactory,
EntityManagerInterface $entityManager,
RouterInterface $router,
FlashBagInterface $flashBag,
AuthorizationCheckerInterface $authorizationChecker
){
$this->twig = $twig;
$this->bancoRepository = $bancoRepository;
$this->formFactory = $formFactory;
$this->entityManager = $entityManager;
$this->router = $router;
$this->flashBag = $flashBag;
$this->authorizationChecker = $authorizationChecker;
}
/**
* @Route("/cadastro/bancos", name="cadastro_banco")
*/
public function index(TokenStorageInterface $tokenStorage){
$usuario = $tokenStorage->getToken()->getUser();
$html = $this->twig->render('bancos/index.html.twig', [
'bancos' => $this->bancoRepository->findBy(array('usuario' => $usuario))
]);
return new Response($html);
}
/**
* @Route("/banco/{id}", name="editar")
*/
public function editarBanco(Banco $banco, Request $request) {
$form = $this->formFactory->create(
BancoType::class,
$banco
);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()){
$this->entityManager->flush();
return new RedirectResponse($this->router->generate('cadastro_banco'));
}
return new Response(
$this->twig->render(
'bancos/cadastro.html.twig',
['form' => $form->createView()]
));
}
/**
* @Route("/cadastro/cadastrar-banco", name="cadastro_banco-nova")
*/
public function cadastrar(Request $request, TokenStorageInterface $tokenStorage){
$usuario = $tokenStorage->getToken()->getUser();
$banco = new Banco();
$banco->setUsuario($usuario);
$form = $this->formFactory->create(BancoType::class, $banco);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()){
$this->entityManager->persist($banco);
$this->entityManager->flush();
return new RedirectResponse($this->router->generate('cadastro_banco'));
}
return new Response(
$this->twig->render(
'bancos/cadastro.html.twig',
['form' => $form->createView()]
)
);
}
}
问题是,当我访问/ banco / {id}时,出现错误:
"Cannot autowire argument $banco of "App\Controller\BancoController::editarBanco()": it references class "App\Entity\Banco" but no such service exists."
我的service.yaml都是默认设置,因此我猜它应该可以自动运行。 实体未显示在bin / console debug:container中。
如果我这样在services.yaml中手动声明实体
App\Entity\Banco:
autowire: true
autoconfigure: true
public: false
它可以工作,但是现在当我访问/ banco / {id}时,表单将变为空,而数据库中不存在该信息,并且如果我输入并提交该信息,则数据库中没有任何变化。
如果我转到调试工具栏并检查查询,则似乎是在查询登录用户的ID,而不是实体“ Banco”的ID。
顺便说一句,该实体表具有FK user_id。也许这就是问题所在? 我迷路了,所以我需要一点帮助。我是PHP / Symfony的新手。 谢谢

好吧,由于某些未知原因,SensioFrameworkExtraBundle尚未完全安装。
我刚刚运行了“ $作曲家需要注释”,现在一切都按预期运行。
该死,浪费了2天的时间来解决这个问题。
谢谢大家!

Symfony将自动连接实体,但是它将是一个空的实体。更好的方法是自动连接存储库,从请求中获取ID,然后通过ID从存储库中获取Banco。

从5.2版开始,不赞成使用SensioFrameworkExtraBundle的路由注释,因为它们现在是Symfony的核心功能。

您可以尝试清理它们(尝试之前备份composer.json)
更新composer.json “要求”:{ “ symfony / symfony”:“ ^ 4.3”, }, 运行这些命令;
composer update symfony/symfony
composer update "symfony/*" --with-all-dependencies
