Groups Annotations don't works - php

Question

Symfony 3.1.7 + FOSRestBundle latest version
<?php
namespace PM\ApiBundle\Controller;
...
use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\View\View;
class ArticlesController extends FOSRestController
{
/**
* #ApiDoc(
* section="articles",
* resource=true,
* description="Get articles published"
* )
* #Rest\View(serializerGroups={"article"})
* #Rest\Get("/articles")
*/
public function getArticlesAction(Request $request)
{
$articles = $this->getDoctrine()
->getManager()
->getRepository('PMPlatformBundle:Article')
->findAllDateDesc();
/* #var $articles Article[] */
return $articles;
}
Then in my Article entity I added this annotation #Groups({"article"}) with the right use statement.
Whit default serializer I get :
[
[],
[]
]
Whit JMS serializer (bundle) I get :
{
"0": {},
"1": {}
}
(I have two articles in db)
it seems like the "article" group is not recognized. When I use the default serializer whithout this annotations I get a circular error.
What's wrong ?
[EDIT] Same behavior with
/**
* #ApiDoc(
* section="articles",
* resource=true,
* description="Get articles published"
* )
* #Rest\View()
* #Rest\Get("/articles")
*/
public function getArticlesAction(Request $request)
{
$context = new Context();
$context->addGroup('article');
$articles = $this->getDoctrine()
->getManager()
->getRepository('PMPlatformBundle:Article')
->findAllDateDesc();
/* #var $articles Article[] */
$view = $this->view($articles, 200);
$view->setContext($context);
return $view;
}
The response still empty.

Answer 1

You can keep the default serializer of symfony. No need of JMSSerializer.
You may have forgotten to activate the annotations of serializer in config.yml (https://symfony.com/doc/current/serializer.html#using-serialization-groups-annotations)
#app/config/config.yml
framework:
....
serializer: { enable_annotations: true }
It is necessary to force the view_response_listener in config.yml (http://symfony.com/doc/master/bundles/FOSRestBundle/3-listener-support.html, http://symfony.com/doc/master/bundles/FOSRestBundle/view_response_listener.html)
#app/config/config.yml
fos_rest:
view:
view_response_listener: 'force'
That should work !

Ok I fixed it using JMS serializer like this :
use JMS\Serializer\SerializationContext;
use JMS\Serializer\SerializerBuilder;
class ArticlesController extends FOSRestController
{
/**
* #ApiDoc(
* section="articles",
* resource=true,
* description="Get articles published"
* )
* #Rest\View()
* #Rest\Get("/articles")
*/
public function getArticlesAction(Request $request)
{
$serializer = SerializerBuilder::create()->build();
$articles = $this->getDoctrine()
->getManager()
->getRepository('PMPlatformBundle:Article')
->findAllDateDesc();
/* #var $articles Article[] */
return $serializer->serialize($articles, 'json', SerializationContext::create()->setGroups(array('article')));
}
Now the groups annotations works fine.

Answer 3

try php bin/console cache:clear

Answer 4

Using your suggested answer
$serializer = SerializerBuilder::create()->build();
return $serializer->serialize($collection, 'json', SerializationContext::create()->setGroups(['group']));
returns JSON as string to me. To solve your problem, you have to have the following in your config.yml file:
jms_serializer:
metadata:
auto_detection: true
this is how it recognises mappings that you specify with your annotations in Entity files. More info on it here: docs. Having that, you can use the #View(serializerGroups={"group"}) annotation as you wanted.
P.S. Symfony 3.2.2; JMSSerializer 1.1; FOSRestBundle 2.1
