I'm stuck with the following problem: I want to fetch doctrine entities of a specific locale without breaking the default behavior of my Symfony app.
Here is an example of one of my entity:
use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;
/**
* @ORM\Entity(repositoryClass="ProductRepository")
* @ORM\Table(name="product")
* @ORM\InheritanceType("SINGLE_TABLE")
* @ORM\DiscriminatorColumn(name="discr", type="string")
*/
class Product
{
/**
* @var integer $id
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @var string
* @ORM\Column(name="name", type="string")
* @Gedmo\Translatable
*/
protected $name;
// ...
}
The a part of related doctrine repository:
class ProductRepository extends \Doctrine\ORM\EntityRepository
{
public function findOneProductInLocale($id, $locale)
{
$qb = $this->createQueryBuilder('p')
->select('p')
->where('p.id = :id')
->setMaxResults(1)
->setParameter('id', $id);
;
$query = $qb->getQuery();
$query->setHint(
\Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER,
'Gedmo\\Translatable\\Query\\TreeWalker\\TranslationWalker'
);
// force Gedmo Translatable to not use current locale
$query->setHint(
\Gedmo\Translatable\TranslatableListener::HINT_TRANSLATABLE_LOCALE,
$locale
);
$query->setHint(
\Gedmo\Translatable\TranslatableListener::HINT_FALLBACK,
1
);
return $query->getOneOrNullResult();
}
}
and a part of my scripts:
// default Locale: en
// request Locale: de
$repo = $em->getRepository('Acme\\Entity\\Product');
$product1 = $repo->findOneById($id);
echo $product1->getName(); // return 'Name (DE)'
$product_de = $repo->findOneProductInLocale($id, 'de');
echo $product_de->getName(); // return 'Name (DE)';
$product_en = $repo->findOneProductInLocale($id, 'en');
echo $product_en->getName(); // return 'Name (EN)'
echo $product1->getName(); // return 'Name (EN)' instead of 'Name (DE)' !! <-- What is wrong?
// even if I refetch a product
$product2 = $repo->findOneById($id);
echo $product2->getName(); // return 'Name (EN)' without taking anymore in account the current locale
Is someone now why this didn't work as expected ?
Is something wrong in my implementation of ProductRepository::findOneProductInLocale()
?
Any help or hint is welcome.
I know I'm kind of late with my answer, but I face the same issue & found a solution. I hope it will help some other developers.
Your findOneProductInLocale
if perfectly fine.
It works as design - when you will use findOneProductInLocale
, the query will search in the given locale, but the final entity will always be loaded in the current locale, you can't change it.
Once the entity has been found via findOneProductInLocale
& loaded in the current locale, you can get the locale variant you need by using setTranslatableLocale
method of Gedmo & refreshing your entity as explain by @umadesign
// Reload the entity in different languages.
$entity->setTranslatableLocale($locale);
$em->refresh($entity);
(Optional) You may need to add the setTranslatableLocale
method & the companion property $local
to your translatable entity
class Product {
// ...
/**
* @Gedmo\Locale
* Used locale to override Translation listener`s locale
* this is not a mapped field of entity metadata, just a simple property
*/
private $locale;
/**
* Set the locale to use for translation listener
*
* @param string $locale
*
* @return static
*/
public function setTranslatableLocale($locale) {
$this->locale = $locale;
return $this;
}
// ...
}
You can find the complete explanation in the Gedmo documentation under "Basic usage examples" subsection.
