CRUD

We can generate CRUD code for entity:

php bin/console make:crud

This command will generate files:

• Controller: src/Controller/ProductController.php
• Form Type: src/Form/ProductType.php
• Templates:
  • templates/product/_delete_form.html.twig
  • templates/product/_form.html.twig
  • templates/product/edit.html.twig
  • templates/product/index.html.twig
  • templates/product/new.html.twig
  • templates/product/show.html.twig

Controller:

namespace App\Controller;

use App\Entity\Product;
use App\Form\ProductType;
use App\Repository\ProductRepository;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Attribute\Route;
