Custom JSON serializers for a Symfony 3 entity

Question

I have a Symfony 3.2 entity using Doctrine's Translatable extension.

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;
use Symfony\Component\Serializer\Annotation\Groups;

/**
 * Media
 *
 * @ORM\Table(name="medias")
 * @Gedmo\TranslationEntity(class="AppBundle\Entity\Translation\MediaTranslation")
 */
class Media implements Translatable
{
    /* [...] */
    
    /**
     * @var string|null
     *
     * @ORM\Column(type="text", nullable=true)
     * @Gedmo\Translatable
     * @Groups({"single_media"})
     */
    private $description;

    /* [...] */
}

I know how to use the basic way to serialize this entity in JSON (I use friendsofsymfony/rest-bundle for the serialization of my REST API), but I would like to serialize it in a custom way like this...

{
    "description": {
        "fr": "description en français",
        "en": "english description",
    }
}

What serializer are you using? Symfony Serializer, JMS Serializer, other one? – Sp

try this :

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;
use Symfony\Component\Serializer\Annotation\Groups;

/**
 * Media
 *
 * @ORM\Table(name="medias")
 * @Gedmo\TranslationEntity(class="AppBundle\Entity\Translation\MediaTranslation")
 */
class Media implements Translatable, \Serializable
{
    /* [...] */

    /**
     * @var string|null
     *
     * @ORM\Column(type="text", nullable=true)
     * @Gedmo\Translatable
     * @Groups({"single_media"})
     */
    private $description;

    /* [...] */
}
