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
