Translation bundle for ApiPlatform based on Sylius translation

Installation:

$ composer require locastic/api-platform-translation-bundle

Implementation:

Translatable entity:

  • Extend your model/resource with Locastic\ApiTranslationBundle\Model\AbstractTranslatable
  • Add createTranslation() method which returns new object of translation Entity. Example:
use Locastic\ApiPlatformTranslationBundle\Model\AbstractTranslatable;
use Locastic\ApiPlatformTranslationBundle\Model\TranslationInterface;

class Post extends AbstractTranslatable
{
    // ...
    
    protected function createTranslation(): TranslationInterface
    {
        return new PostTranslation();
    }
}
  • Add a translations-property. Add the translations serializations group and make a connection to the translation entity:
use Locastic\ApiPlatformTranslationBundle\Model\AbstractTranslatable;

class Post extends AbstractTranslatable
{
    // ...
    
    /**
     * @ORM\OneToMany(targetEntity="PostTranslation", mappedBy="translatable", fetch="EXTRA_LAZY", indexBy="locale", cascade={"PERSIST"}, orphanRemoval=true)
     *
     * @Groups({"post_write", "translations"})
     */
    protected $translations;
}
  • Add virtual fields for all translatable fields, and add read serialization group. Getters and setters must call getters and setters from translation class. Example:
use Locastic\ApiPlatformTranslationBundle\Model\AbstractTranslatable;
use Symfony\Component\Serializer\Annotation\Groups;

class Post extends AbstractTranslatable
{
    // ...
    
    /**
    * @Groups({"post_read"})
    */
    private $title;
    
    public function setTitle(string $title)
    {
        $this->getTranslation()->setTitle($title);
    }

    public function getTitle(): ?string
    {
        return $this->getTranslation()->getTitle();
    }
}

Translation entity:

  • Add entity with all translatable fields. Name needs to be name of translatable entity + Translation
  • Extend Locastic\ApiPlatformTranslationBundle\Model\AbstractTranslation
  • Add serialization group translations to all fields and other read/write groups. Example Translation entity:
use Symfony\Component\Serializer\Annotation\Groups;
use Locastic\ApiPlatformTranslationBundle\Model\AbstractTranslation;

class PostTranslation extends AbstractTranslation
{
    // ...

    /**
     * @ORM\ManyToOne(targetEntity="Post", inversedBy="translations")
     */
    protected $translatable;
    
    /**
     * @ORM\Column(type="string")
     * 
     * @Groups({"post_read", "post_write", "translations"})
     */
    private $title;
    
    /**
     * @ORM\Column(type="string")
     *
     * @Groups({"post_write", "translations"})
     */
    protected $locale;

    public function setTitle(string $title): void
    {
        $this->title = $title;
    }

    public function getTitle(): ?string
    {
        return $this->title;
    }
}

Api resource

  • Add translation.groups filter if you would like to have option to return all translation objects in response. If you don't use translations group, response will return only requested locale translation or fallback locale translation.
  • Add translations to normalization_context for PUT and POST methods to make sure they return all translation objects.
  • Example:
AppBundle\Entity\Post:
    itemOperations:
        get:
            method: GET
        put:
            method: PUT
            normalization_context:
                groups: ['translations']
    collectionOperations:
        get:
            method: GET
        post:
            method: POST
            normalization_context:
                groups: ['translations']
    attributes:
        filters: ['translation.groups']
        normalization_context:
            groups: ['post_read']
        denormalization_context:
            groups: ['post_write']

Usage:

Language param for displaying single translation:

?locale=de

Or use Accept-Language http header

Accept-Language: de

Serialization group for displaying all translations:

?groups[]=translations

POST translations example

{
    "datetime":"2017-10-10",
    "translations": { 
        "en":{
            "title":"test",
            "content":"test",
            "locale":"en"
        },
        "de":{
            "title":"test de",
            "content":"test de",
            "locale":"de"
        }
    }
}

EDIT translations example

{
    "datetime": "2017-10-10T00:00:00+02:00",
    "translations": {
        "de": {
          "id": 3,
          "title": "test edit de",
          "content": "test edit de",
          "locale": "de"
        },
        "en": {
          "id": 2,
          "title": "test edit",
          "content": "test edit",
          "locale": "en"
        }
    }
}
