我目前正在做一个基本的Symfony项目来发现这个框架，我的网站识别了一些法国说唱专辑并提供了有关它的信息，然后我创建了2个控制器："DefaultController"和"AlbumsController"。在第一个中，我实现了一些功能来显示一些音乐歌词，并且我使用路径名作为链接，效果很好，但是使用第二个控制器，我做了完全相同的事情，但它不起作用。(对不起，英语不好(。 附加 -> 有问题的代码 默认控制器 ：
<?php
namespace AppController;
use AppEntityMusique;
use AppFormAlbumsType;
use DoctrineCommonPersistenceObjectManager;
use SymfonyBundleFrameworkBundleControllerAbstractController;
use AppControllerAlbumsController;
use AppRepositoryAlbumsRepository;
use AppRepositoryMusiqueRepository;
use SymfonyComponentRoutingAnnotationRoute;
use SymfonyComponentHttpFoundationRequest;
use AppEntityAlbums;
class DefaultController extends AbstractController
{
/**
* @Route("/", name="index")
*/
public function index()
{
return $this->render('index.html.twig', [
'title' => 'Accueil',
]);
}
/**
* @Route("/albums", name="albums")
*/
public function albums()
{
$repo = $this->getDoctrine()->getRepository(Albums::class);
$albums = $repo->findAll();
return $this->render('albums/index.html.twig', [
'albums' => $albums,
]);
}
/**
* @Route("/musiques", name="musiques")
*/
public function musiques()
{
$repo = $this->getDoctrine()->getRepository(Musique::class);
$musiques = $repo->findAll();
return $this->render('musiques.html.twig', [
'title' => 'Liste des Musiques',
'$musiques' => $musiques,
]);
}
/**
* @Route("/musiques/{id}", requirements={"id": "[1-9]d*"}, name="randMusique")
* @throws Exception
*/
public function randomMusique()
{
$random = random_int(1, 100);
$repo = $this->getDoctrine()->getRepository(Musique::class);
$musique = $repo->find($random);
return $this->render('randomMusique.html.twig', [
'musique' => $musique,
]);
}
}
