FOSRestBundle woes with Symfony4, 204 no content response - json

Question

I've made a rest controller for Movie objects with a get action.
My database manager one movies with id:3.
When I try to access localhost:8000/api/movie/3 or any other idea for that matter it goes straight back to the page I came from, with only a hint of no content response.
[Tue May 29 16:06:42 2018] 127.0.0.1:61540 [204]: /api/movie/3
I have the following configurations:
services.yaml
services:
...
sensio_framework_extra.view.listener:
alias: Sensio\Bundle\FrameworkExtraBundle\EventListener\TemplateListener
...
routes/rest.yaml
movies:
type: rest
resource: App\Controller\MovieController
prefix: /api
packages/fos_rest.yaml
fos_rest:
param_fetcher_listener: true
allowed_methods_listener: true
routing_loader:
include_format: false
view:
view_response_listener: 'force'
format_listener:
rules:
- { path: '^/api', priorities: ['json'], fallback_format: 'json' }
zone:
- { path: ^/api/* }
packages/framework.yaml:
framework:
...
templating: { engines: ['twig'] }
And the following files:
Controller/MovieController.php
<?php
namespace App\Controller;
use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\Routing\ClassResourceInterface;
use FOS\RestBundle\Controller\FOSRestController;
/**
* #Rest\RouteResource("Movie", pluralize=false)
*/
class MovieController extends FOSRestController implements ClassResourceInterface {
/**
* #Rest\View()
* #Rest\Get("/movie/{id}")
*/
public function getAction(string $id) {}
}
Entity/Movie.php
<?php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="App\Repository\MovieRepository")
*/
class Movie {
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=32)
*/
private $title;
public function __construct($title) {
$this->title = $title;
}
...
}
Debug router is giving me this result:
$ bin/console debug:router | grep movie
get_movie GET ANY ANY /api/movie/{id}
[update]
Due to earlier wrong configurations I encountered the errors:
1
Warning: ReflectionObject::__construct() expects parameter 1 to be object, null given
2
An instance of Symfony\Bundle\FrameworkBundle\Templating\EngineInterface >must be injected in FOS\RestBundle\View\ViewHandler to render templates.
3
Type error: Argument 2 passed to Twig_Environment::render()
must be of the type array
4
There are no registered paths for namespace "FOSRest".
5
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Answer 1

I had to edit MovieController to return the object or return an exception.
MovieController.php
<?php
namespace App\Controller;
use App\Repository\MovieRepository;
use Doctrine\ORM\EntityManagerInterface;
use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\Routing\ClassResourceInterface;
use FOS\RestBundle\Controller\FOSRestController;
/**
* #Rest\RouteResource("Movie", pluralize=false)
*/
class MovieController extends FOSRestController implements ClassResourceInterface {
/**
* #var EntityManagerInterface
*/
private $entityManager;
/**
* #var MovieRepository
*/
private $movieRepository;
public function __construct(
EntityManagerInterface $entityManager,
MovieRepository $movieRepository
) {
$this->entityManager = $entityManager;
$this->movieRepository = $movieRepository;
}
public function getAction(string $id) {
$movie = $this->movieRepository->find($id);
if($movie === null) {
throw new NotFoundHttpException();
}
return $this->view($movie);
}
}

Answer 2

you should add populateDefaultVars in the view annotation parameters like this :
/**
*
* #rest\View(populateDefaultVars=false)
*/
