How do I get Id in the URL to display comments with Symfony 5?

I’m coding a blog with Symfony 5 and I have issues getting the Id from the URL to display comments from my Database.

To sum up : – I have a view “/fiche/{id}” wish displays specific game informations. – People can leave a comment below, the comment goes in Database with a foreign Key named “jeu_id” wish is the game where the comment were posted.

• The goal is to display now all the comments wish were posted on this specific game. I want to display all the comments with foreign key “jeu_id” wish is in the url “/fiche/{id}”.

Here’s the method in my controller :

     /**
     * @Route("/fiche/{id}", name="fiche", methods={"POST", "GET"})
     */
    public function fiche($id, Jeux $jeux, Request $request): Response
    {
        $id = (int)$request->get('id');
        $commentaires = $this->getDoctrine()->getRepository(Jeux::class)->find($id);

        $commentaire = new Commentaires();
        $commentaire->setCreatedAt(new DateTime("NOW"));
        $request = Request::createFromGlobals();
        $commentaire->setJeu($jeux);
        $form = $this->createForm(CommentairesType::class, $commentaire);
        $form->handleRequest($request);

        //test variable
        //dd($id);
        dd($commentaire->getJeu($id));

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

            return $this->redirectToRoute('liste');
        }
        return $this->render('main/fiche.html.twig', [
            'commentaires' => $commentaires,
            'jeux' => $jeux,
            'form' => $form->createView(),
        ]);
    }

Here’s the concern variables in entity “Commentaires” :

    /**
     * @ORMManyToOne(targetEntity=Jeux::class, inversedBy="commentaires")
     * @JoinColumn(name="jeu_id", referencedColumnName="id")
     * @ORMJoinColumn(nullable=true)
     */
    private $jeu;

    public function getJeu(): ?Jeux
    {
        return $this->jeu;
    }

    public function setJeu($jeu): self
    {
        $this->jeu = $jeu;

        return $this;
    }

Here’s the concern variables in entity “Jeux” :

    /**
     * @ORMOneToMany(targetEntity=Commentaires::class, mappedBy="jeu", orphanRemoval=true)
     */
    private $commentaires;

    /**
     * @return Collection|Commentaires[]
     */
    public function getCommentaires(): Collection
    {
        return $this->commentaires;
    }

Answer

I think the right way would be something like this:

/**
 * @Route("/fiche/{jeux}", 
 * name="fiche"
 */
public function fiche(Request $request, Jeux $jeux, EntityManagerInterface $em): Response
{
    $form = $this->createForm(CommentaireType::class);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        $commentaire = $form->getData();
        $commentaire->setCreatedAt(new DateTime("NOW"));
        $jeux->addCommentaire($commentaire);

        $em->persist($commentaire);
        $em->flush();

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

    return $this->render('main/fiche.html.twig', [
        'commentaires' => $jeux->getCommentaires(),
        'jeux' => $jeux,
        'form' => $form->createView(),
    ]);
}
