Custom i18n routing in Symfony - symfony

Question

I'm using JMS\I18nRoutingBundle, Gedmo\Translatable and Gedmo\Sluggable. Routes with default locations works as well, but other locales works without translated slug. My i18n routing have following settings:
# Doctrine extensions
stof_doctrine_extensions:
default_locale: %locale%
translation_fallback: true
orm:
default:
#…
sluggable: true
translatable: true
loggable: false
#…
jms_i18n_routing:
default_locale: cs_CZ
locales: [cs_CZ, en_US]
strategy: custom
hosts:
cs_CZ: example.cz
en_US: example.com
redirect_to_host: true
When I set up route like this:
hw_category:
pattern: /category/{slug}
defaults: { _controller: AcmeSiteBundle:Category:detail }
/**
* #Template
*/
public function detailAction(Category $category)
{}
This routes works
example.cz/category/slug-in-czech
example.com/category/slug-in-czech
But I want to get work example.com/category/slug-in-english which throws 404 exception object not found.

In your controller, you have to override method used in entity repository:
/**
* #Template
* #ParamConverter(
* "category",
* class = "AcmeSiteBundle:Category",
* options = {
* "repository_method" = "findByTranslatedSlug"
* }
* )
*/
public function detailAction(Category $category)
{}
namespace Acme\Bundle\SiteBundle\Entity;
use Doctrine\ORM\EntityRepository;
class CategoryRepository extends EntityRepository
{
public function findByTranslatedSlug($slug)
{
$qb = $this->createQueryBuilder('c')
->where('c.slug = :slug')
->setParameters($slug);
$query = $qb->getQuery();
// set the translation query hint
$query->setHint(
\Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER,
'Gedmo\\Translatable\\Query\\TreeWalker\\TranslationWalker'
);
return $query->getOneOrNullResult();
}
}

As i see you are using the ParamConverter to automatically fetch your category.
If slug-in-englishis an existing slug in your database but doctrine refuses to fetch it.
You probably don't have the TranslatableListener added to your EntityManager at that point.
Example:
$translatableListener = new \Gedmo\Translatable\TranslationListener();
$translatableListener->setTranslatableLocale('en_us');
$em->addEventSubscriber($translatableListener);
If you're using StofDoctrineExtensionsBundle:
stof_doctrine_extensions:
default_locale: en_US
orm:
default:
# ...
translatable: true

I had the same issue and as suggested by jkucharovic, you can use the Doctrine ParamConverter to convert your request parameters to an object
To fetch an object from the database, the Doctrine converter uses by default find() method. But since we use Translatable, therefore multiple tables, it is not enough to manage translations, that's why we need to define our own. Here comes findByTranslatedSlug.
/**
* #Template
* #ParamConverter(
* "category",
* class = "AcmeSiteBundle:Category",
* options = {
* "id" = "slug",
* "repository_method" = "findByTranslatedSlug"
* }
* )
*/
public function detailAction(Category $category)
{}
Some details about ParamConverter parameters:
First parameter "category" refers to the name of the method argument (here $category)
"id" option refers to the route placeholder you want to pass(here {slug}) to the customised repository method (findByTranslatedSlug()). Without setting this option, it would throw a PDO exception.
namespace Acme\Bundle\SiteBundle\Entity;
use Doctrine\ORM\EntityRepository;
class CategoryRepository extends EntityRepository
{
public function findByTranslatedSlug($slug)
{
$qb = $this->createQueryBuilder('c')
->where('c.slug = :slug')
->setParameter('slug',$slug);
$query = $qb->getQuery();
// set the translation query hint
$query->setHint(
\Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER,
'Gedmo\\Translatable\\Query\\TreeWalker\\TranslationWalker'
);
// If you need to set manually the locale to en_US, you can set this query hint
//$query->setHint(\Gedmo\Translatable\TranslatableListener::HINT_TRANSLATABLE_LOCALE, 'en_US');
return $query->getOneOrNullResult();
}
}
I hope this can help

For Symfony > 4
the work around is
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Entity;
* #Route("/{slug}", name="your_route_name"))
* #Entity("your_entity_name", expr="repository.findByTranslatedSlug(slug)")
and use the repo method from the accepted answer ;)
Searching for this the whole day, i'm glad i found your post !
