How to get groups working for JMSSerializerBundle and FOSRestBundle? - symfony

Question

I am trying to set up different groups to achieve different types of serialization of my entities depending on the context.
My config looks like this:
My\FooBundle\Entity\Asset:
exclusion_policy: ALL
access_type: public_method
properties:
id:
access_type: property
expose: true
groups: [fnord]
name:
expose: true
path:
expose: true
isInQuarantine:
expose: true
groups: [baz]
I expect that the group having properties should not be exposed unless the group is set.
I am trying to set the group in my controller via:
$view->setSerializationContext(SerializationContext::create()->setGroups(array('fnord')));
Yet there is no effect on what is exposed and what isn't. Even if I do not try to change the SerializationContext, the groups options seems to be always ignored.
I know that my config is working because I can toggle the properties via the expose flag.
Yet what am I doing wrong here?

I know this question is a bit old, but it may help others.
I encountered a similar issue.
This was because I had in my controler (that extends FOSRestControler) a method with multiple calls to
$this->getView()
You have to notice that this method creates a new View object.
That means, if you call multiple getView methods, the context get reset.
Have a look at the following code that worked for my app :
use FOS\RestBundle\Controller\FOSRestController as Controller;
class RestController extends Controller
{
public function getUserAction($username)
{
$view = $this->view();
$view->setSerializationContext(SerializationContext::create()->setGroups(array('Product')));
$user = $this->getDoctrine()->getManager()->getRepository('VendorUserBundle:User')->findOneByUsername($username);
if(!is_object($user))
{
throw $this->createNotFoundException();
}
$view->setData($user);
return $view;
}
}
In Model.User.yml file :
FOS\UserBundle\Model\User:
exclusion_policy: ALL
properties:
username:
expose: true
groups: [fnord]
email:
expose: true
groups: [Product]
enabled:
expose: true
groups: [Product]
roles:
expose: true
groups: [Product]
Gives the following output :
{"email":"guiguiboy#xxx.com","enabled":true,"roles":["ROLE_XXX"]}
I didn't have any cache related problems (dev env used).
