How to generate a crud in symfony

How to generate a crud in symfony 5? , To create a crud in symfony 5 you need to add the following process

How to generate a crud in symfony 5

First it is necessary to create the entity, for this example we will create an entity called User, with the following command

php bin/console make:entity User

Once the entity is created we can proceed to create the crud, we continue with the next step

php bin/console make:crud User

Once the process is finished, a default structure will be created, in the template/user folder you will find the necessary files with a .twig extension, which are the following


  • _delete_form.html.twig
  • _form.html.twig
  • edit.html.twig
  • index.html.twig
  • new.html.twig
  • show.html.twig

Each of these files will extend by default the base.html.twig file

Each of these views will be associated with a controller which will be called UserController.php , and will have the following structure by default

 

namespace App\Controller;

use App\Entity\User;
use App\Form\UserType;
use App\Repository\UserRepository;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

/**
 * @Route("/user")
 */
class UserController extends AbstractController
{
    /**
     * @Route("/", name="user_index", methods={"GET"})
     */
    public function index(UserRepository $userRepository): Response
    {        
        
        return $this->render('user/index.html.twig', [
            'users' => $userRepository->findAll(),
        ]);
    }

    /**
     * @Route("/new", name="user_new", methods={"GET","POST"})
     */
    public function new(Request $request): Response
    {
        $user = new User();
        $form = $this->createForm(UserType::class, $user);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $entityManager = $this->getDoctrine()->getManager();
            $entityManager->persist($user);
            $entityManager->flush();

            return $this->redirectToRoute('user_index');
        }

        return $this->render('user/new.html.twig', [
            'user' => $user,
            'form' => $form->createView(),
        ]);
    }

    /**
     * @Route("/{id}", name="user_show", methods={"GET"})
     */
    public function show(User $user): Response
    {
        return $this->render('user/show.html.twig', [
            'user' => $user,
        ]);
    }

    /**
     * @Route("/{id}/edit", name="user_edit", methods={"GET","POST"})
     */
    public function edit(Request $request, User $user): Response
    {
        $form = $this->createForm(UserType::class, $user);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $this->getDoctrine()->getManager()->flush();

            return $this->redirectToRoute('user_index');
        }

        return $this->render('user/edit.html.twig', [
            'user' => $user,
            'form' => $form->createView(),
        ]);
    }

    /**
     * @Route("/{id}", name="user_delete", methods={"DELETE"})
     */
    public function delete(Request $request, User $user): Response
    {
        if ($this->isCsrfTokenValid('delete'.$user->getId(), $request->request->get('_token'))) {
            $entityManager = $this->getDoctrine()->getManager();
            $entityManager->remove($user);
            $entityManager->flush();
        }

        return $this->redirectToRoute('user_index');
    }
}

And with these simple steps we have created a CRUD in a short time, a necessary thing that a symfony framework developer must know
