Serialize translateble entity - symfony

Question

For translate my entity product use next code
use Knp\DoctrineBehaviors\Model as ORMBehaviors;
class Product
{
/**
* #Groups({"prod_translate"})
*/
use ORMBehaviors\Translatable\Translatable;
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #Groups({"prod"})
*/
private $id;
...
Translatable create new entity ProductTranslation with table in DB product_translation with id, translatable_id, locale and translatble properties.
Translation work perfectly. In page just write {{ product.translation.en/sp.name }}
When use ajax pagenation use serializer for return data.
Tried JMS\Serializer\SerializerBuilder and Symfony\Component\Serializer\Serializer
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
use Doctrine\Common\Annotations\AnnotationReader;
$products = $em->getRepository('AppBundle:Product')->findNextPageByBrandCategoryIds( array($cat), $brand, $offset, $limit );
$classMetadataFactory = new ClassMetadataFactory(new AnnotationLoader(new AnnotationReader()));
$normalizer = new ObjectNormalizer($classMetadataFactory);
$normalizer->setCircularReferenceHandler(function ($object) {
return $object->getID();
});
$serializer = new Serializer(array($normalizer));
$jsonObject = $serializer->normalize($products, 'json', array('groups' => array('prod', 'prod_translate')) );
Without groups serializet return "Maximum execution time 180second".
With groups return only Product data without translations.
What annotation or else manipulation must do for fix this issue? Please help!
Edit:
Tried Use next queries:
public function findNextPageByBrandCategoryIds(array $cat_ids, $brand_id, $offset=0, $limit=8 )
{
$qb = $this->createQueryBuilder('p');
if( !empty($cat_ids) ){
$cat_ids = implode(',', $cat_ids);
$qb->join('p.categories', 'c')
->where($qb->expr()->in('c.id', $cat_ids ) );
}
if( !empty($brand_id) ){
$qb->andWhere('p.brand = :brand')
->setParameter('brand', $brand_id);
}
if( $offset>0 ){
$qb->setFirstResult( $offset );
}
$qb->setMaxResults( $limit );
return $qb->getQuery()->getResult();
}
private function findNextPageByBrandCategoryIds($cat_id, $brand_id, $offset=0, $limit=8 )
{
$em = $this->getDoctrine()->getManager();
$sql = "SELECT p.id, t.id AS translate_id " .
"FROM product p INNER JOIN product_translation t ON t.translatable_id = p.id";
$where .= ' WHERE 1=1 ' ;
$rsm = new ResultSetMappingBuilder($em);
if( !empty($cat_id) ){
$sql .= " LEFT JOIN products_categories c ON c.product_id = p.id ";
$where .= " AND c.category_id = ".$cat_id;
}
if( !empty($brand_id) ){
$where .= " AND p.brand = ".$brand_id;
}
$limit = ' LIMIT '.$limit;
if( $offset>0 ){
$limit .= ' OFFSET '.$offset;
}
$sql = $sql.$where.$limit;
$rsm->addRootEntityFromClassMetadata('AppBundle\Entity\Product', 'p');
$rsm->addJoinedEntityFromClassMetadata('AppBundle\Entity\ProductTranslation', 't', 'p', 'product', array('id' => 'translatable_id'));
$query = $em->createNativeQuery($sql, $rsm);
return $query->getResult();
}
Debug almost every line - they are right.
If use setHint(\Doctrine\ORM\Query::HINT_FORCE_PARTIAL_LOAD, true) - work but return products only, without translations.

Answer 1

The Maximum execution time 180 second message is an error that has nothing to do with annotations or the serializer.
In your php.ini you have a max_execution_time option to configure the limit of a script in seconds. You can also set it with the function set_time_limit($seconds)by code, but I would not recommend to use it.
Anyway, I would bet that you are doing a very large query. How many results are you limiting?

Nik fix this issue:
On Brand, Category and Product Entities
use JMS\Serializer\Annotation\MaxDepth;
/**
* #MaxDepth(1)
*/
private $products;
/**
* #MaxDepth(1)
*/
private $categories;
/**
* #MaxDepth(1)
*/
private $brand;
