FOSUserBundle + JMSSerializerBundle + exposing extra fields - symfony

Question

I have an issue when serializing a User instance with one additional field $name, which extends the base User from FOSUserBundle:
<?php
namespace AppBundle\Entity\User;
use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Model\User as BaseUser;
/**
* User
*/
class User extends BaseUser
{
/**
* #var string
*/
private $name;
/**
* Set name
* #param string $name
* #return User
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
* #return string
*/
public function getName()
{
return $this->name;
}
}
To simplify, I need to expose only $salt field from User entity using JMSSerializerBundle
#AppBundle\Resources\config\serializer\Model.User.yml
FOS\UserBundle\Model\User:
exclusion_policy: all
properties:
salt:
expose: true
Here's the config for it:
#app\config\config.yml
jms_serializer:
metadata:
auto_detection: true
directories:
FOSUserBundle:
namespace_prefix: "FOS\\UserBundle"
path: "#AppBundle/Resources/config/serializer"
The issue is that the serializer exposes also $name field, which I don't want as I need only to have $salt exposed:
{
"salt": "abcdefg",
"name": "Admin"
}
I believe I need to tell the serializer to use a config for my AppBundle\Entity\User instead of the base user entity from FOSUserBundle, but I have no clue how to implement it.

This is how I solved the issue . I have a User.php class that
inherit from FOS\UserBundle\Model\User as BaseUser. I need control the serialization from both my BaseUser class and my User class.
Solution: you need 2 separated config file to control each class.
config.yml
#Serializer configuration
jms_serializer:
metadata:
directories:
AppBundle:
path: "#AppBundle/Resources/config/serializer"
FOSUB:
namespace_prefix: "FOS\\UserBundle"
path: "%kernel.root_dir%/serializer/FOSUB"
Model.User.yml
FOS\UserBundle\Model\User:
exclusion_policy: ALL
properties:
id:
expose: true
username:
expose: true
email:
expose: true
enabled:
expose: true
Entity.User.yml
AppBundle\Entity\User:
exclusion_policy: ALL
properties:
imageAvatar:
expose: true
updatedAt:
expose: true
namespace AppBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* User
*
* #ORM\Table(name="usuario")
* #ORM\Entity(repositoryClass="DietaBundle\Repository\UserRepository")
*
*
*/
class User extends BaseUser
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string", length=255)
*
* #var string
*/
private $imageAvatar;
/**
* #ORM\Column(type="datetime")
*
* #var \DateTime
*/
private $updatedAt;
Clear the cache after each change in the configuration files.
cache:clear

It happens because you are using the exclusion_policy: all on the parent entity, instead of on the child entity, which still exposing all of it's properties.
you should switch to your bundle in the configuration (config.yml) under the jms_seriazlier:directories.
any-name:
namespace_prefix: "My\\FooBundle"
path: "#MyFooBundle/Resources/config/serializer"
now you could use the same configuration to expose only the desired property.
#AppBundle\Resources\config\serializer\Entity.User.yml
My\FooBundle\Entity\User:
exclusion_policy: all
properties:
salt:
expose: true
