Too many db queries with DoctrineExtensions Translatable Symfony2 - php

Question

I just installed the Translatable DoctrineExtensions from the StofDoctrineExtensionsBundle.
I have two entities "Space" and "Equipment" with many to one relation :
/**
* Space
* #ORM\Table(name="space")
* #ORM\Entity(repositoryClass="Project\ProjectBundle\Repository\PlaceRepository")
*/
class Space implements Translatable
{
/**
* #var integer
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\OneToMany(targetEntity="Project\ProjectBundle\Entity\Equipment", cascade={"persist"})
*/
private $equipments;
/**
* #var string
* #Gedmo\Translatable
* #ORM\Column(name="name", type="string", length=255, nullable=true)
*/
private $name;
/**
* #Gedmo\Locale
*/
private $locale;
public function setTranslatableLocale($locale)
{
$this->locale = $locale;
}
}
And :
/**
* Equipment
* #ORM\Table("equipment")
* #ORM\Entity(repositoryClass="Project\ProjectBundle\Repository\EquipmentRepository")
*/
class Equipment implements Translatable
{
/**
* #var integer
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
* #Gedmo\Translatable
* #ORM\Column(name="name", type="string", length=255, nullable=true)
*/
private $name;
/**
* #Gedmo\Locale
*/
private $locale;
public function setTranslatableLocale($locale)
{
$this->locale = $locale;
}
}
In the spaceRepository, I have, in my get query function :
public function getSpace($id) {
$query->setHint(\Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER, 'Gedmo\\Translatable\\Query\\TreeWalker\\TranslationWalker');
$query->setHint(\Gedmo\Translatable\TranslatableListener::HINT_TRANSLATABLE_LOCALE,$locale);
$db = $this
->createQueryBuilder('s')
->andWhere('s.id = :id')
->setParameter('id', $id)
->leftJoin('s.equipments', 'e')
->addSelect('e');
$query = $db->getQuery();
$query->setHint(\Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER, 'Gedmo\\Translatable\\Query\\TreeWalker\\TranslationWalker');
$query->setHint(\Gedmo\Translatable\TranslatableListener::HINT_TRANSLATABLE_LOCALE, 'en');
return $query->getSingleResult();
}
The TranslationWalker should get all the results in one single query but it doesn't work, and, finally, I have one query for each equipment (more than 150 queries).
How could I get all translated elements in one single query ?

Try to set the hydration mode manually as your issue is related to this problem.
Take a look at this answer on how to set the hydration mode. It worked for me.
In my case I simply added the following hints to a query
use Doctrine\ORM\Query;
use Gedmo\Translatable\Query\TreeWalker\TranslationWalker;
...
$query->setHydrationMode(TranslationWalker::HYDRATE_OBJECT_TRANSLATION);
$query->setHint(Query::HINT_REFRESH, true);
Hope that helps!
