FOSRestBundle not use JMSSerializerBundle - symfony

Question

I have configured Symfony 3 to auto serialize my action. It works, but the relations aren't serialized:
0
id 1
name "Liste de course"
creation_date "2017-07-07T00:00:00+00:00"
last_update_date "2017-07-07T20:57:06+00:00"
user_entity
_todo_entity_entities
_parent_entity
1
id 2
name "domotique"
creation_date "2017-07-07T00:00:00+00:00"
last_update_date "2017-07-07T21:22:52+00:00"
user_entity
_todo_entity_entities
_parent_entity
If I explicitly use JMSSerializerBundle, it works (user_entity is an object):
0
id 1
name "Liste de course"
creation_date "2017-07-07T00:00:00+00:00"
last_update_date "2017-07-07T20:57:06+00:00"
user_entity Object
_todo_entity_entities
1
id 2
name "domotique"
creation_date "2017-07-07T00:00:00+00:00"
last_update_date "2017-07-07T21:22:52+00:00"
user_entity Object
_todo_entity_entities
I think FOSRestBundle uses the default seralizer, not JMSSerializerBundle:
/**
* #Rest\Get("/projects")
* #View(
* serializerGroups = {"all"}
* )
*/
public function getProjectsAction()
{
$projectEntity = $this->getDoctrine()->getRepository('todoListAdminBundle:Project');
$projects = $projectEntity->findAll();
/*
$data = $this->get('jms_serializer')->serialize($projects, 'json');
// this is work !
$response = new Response($data);
$response->headers->set('Content-Type', 'application/json');
return $response;
*/
return $projects;
}
The entity I serialize :
/**
* Project
*
* #ORM\Table(name="project")
* #ORM\Entity(repositoryClass="todoListAdminBundle\Repository\ProjectRepository")
*/
class Project
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #Serializer\Groups({"all"})
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
* #Assert\Length(max=50)
* #Assert\Type(type="string")
* #Serializer\Groups({"all"})
*/
private $name;
/**
* #var \DateTime
*
* #ORM\Column(name="creation_date", type="date")
* #Assert\DateTime()
* #Serializer\Groups({"all"})
*/
private $creationDate;
/**
* #var \DateTime
*
* #ORM\Column(name="last_update_date", type="datetime")
* #Assert\DateTime()
* #Serializer\Groups({"all"})
*/
private $lastUpdateDate;
/**
*
* #ORM\ManyToOne(targetEntity="PW\UserBundle\Entity\User", inversedBy="projectEntities" , cascade={"persist"}, inversedBy="projectEntities")
* #Assert\Type(type="integer")
* #Serializer\Groups({"all"})
*/
private $userEntity;
/**
* #ORM\OneToMany(targetEntity="todoListAdminBundle\Entity\TodoEntity", mappedBy="projectEntity", fetch="EAGER")
* #Serializer\Groups({"all"})
*/
private $TodoEntityEntities;
/**
* #var int
*
* #ORM\JoinColumn(nullable=true, referencedColumnName="id")
* #ORM\OneToOne(targetEntity="todoListAdminBundle\Entity\Project")
* #Assert\Type(type="integer")
* #Serializer\Groups({"all"})
*/
private $ParentEntity;
My configuration :
fos_rest:
param_fetcher_listener: true
body_listener: true
zone:
- { path: ^/api/* }
body_converter:
enabled: true
view:
formats: { json: true, xml: false, rss: false }
view_response_listener: true
serializer:
serialize_null: true
format_listener:
enabled: true
rules:
- { path: '^/api', priorities: ['json'], fallback_format: 'json' }
routing_loader:
default_format: json
sensio_framework_extra:
view: { annotations: true }
How can I use JMSSerializerBundle automatically ?

Answer 1

First of all, you need to configure JMSSerializer in your config.yml like:
jms_serializer:
metadata:
cache: file
debug: "%kernel.debug%"
file_cache:
dir: "%kernel.cache_dir%/serializer"
auto_detection: true
Then, create directory with serializer for the given entity YourBundleName/Resources/config/serializer/Entity.Project.yml with this code:
YourBundleName\Entity\Project:
exclusion_policy: ALL
properties:
id:
expose: true
name:
expose: true
"exclusion_policy: ALL" - exclude all the fields from the serialized result. And then you add needed fields with "expose: true". Just do not add "ParentEntity" there and you will not see it in the serialized data (also, I do not think, that mix of camel and pascal case is a good practice, but it's the question of taste).
