Undefined method getDoctrine - php

Question

I am a beginner on Symfony 6 and I am blocked because I have an error message: "Undefined method getDoctrine" with Intelephense
Here is my code:
#[Route('/recettes', name: 'app_recettes')]
public function index(int $id): Response
{
$em = $this->getDoctrine()->getManager();
$recette = $em->getRepository(Recettes::class)->findBy(['id' => $id]);
return $this->render('recettes/index.html.twig', [
'RecettesController' => 'RecettesController',
]);
}

Answer 1

Your controller should extends AbstractController from use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
You should not use getDoctrine()->getManager() in symfony 6. If you look into the method from AbstractController you can see:
trigger_deprecation('symfony/framework-bundle', '5.4', 'Method "%s()" is deprecated, inject an instance of ManagerRegistry in your controller instead.', __METHOD__);
You should just autowire your entity manager in your method or constructor and use it directly.
private EntityManagerInterface $entityManager;
public function __construct(EntityManagerInterface $entityManager)
{
$this->entityManager = $entityManager;
}
#[Route('/recettes', name: 'app_recettes')]
public function index(int $id): Response
{
$recette = $this->entityManager->getRepository(Recettes::class)->findBy(['id' => $id]);
return $this->render('recettes/index.html.twig', [
'RecettesController' => 'RecettesController',
]);
}
You could also autowire your RecettesRepository directly instead of the entity manager if you just want to fetch some data.
I'm guessing that you want to show a specific resource by using its id. You probably want to add something /{id} in your route:
#[Route('/recettes/{id}', name: 'app_recettes')]

Answer 2

Dylan response is really good !
If you want to fecth a specific recette (blog de cuisine?), you can autowire the 'recette' as an argument :
#[Route('/recettes/{id}', name: 'app_recettes')]
public function index(Recette $recette): Response
{
return $this->render('recettes/index.html.twig', [
'recette' => $recette,
]);
}
To do so, don't forget to install and import :
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Entity;
