Symfony 2 - Generate Slugs with Gedmo\Slug

Question

I have just installed the doctrine extensions to use Sluggable.

I make this :

composer.json

"stof/doctrine-extensions-bundle": "1.2.*@dev"

AppKernel.php

new Stof\DoctrineExtensionsBundle\StofDoctrineExtensionsBundle(),

app/config/config.yml

stof_doctrine_extensions:
    orm:
        default:
            sluggable: true

Djoo\AppliBundle\Entity\Nomenclature.php

namespace Djoo\AppliBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\DBAL\Types\SmallIntType;
use Gedmo\Mapping\Annotation as Gedmo;

/**
 * Nomenclature
 *
 * 
 * @ORM\Table(name="app_nomenclature")
 * @ORM\Entity
 */
class Nomenclature
{
    .....
    /**
     * @var string
     *
     * @ORM\Column(name="titre", type="string", length=200, nullable=false)
     */
    private $titre;

    /**
     * @var string
     *
     * @ORM\Column(name="finess", type="string", length=10, nullable=true)
     */
    private $finess;

    /**
     * @Gedmo\Slug(fields={"titre","finess"},suffix=".html")
     * @ORM\Column(length=128, unique=true,nullable=true)
     */
    private $slug;

    public function getSlug() {
        return $this->slug;
    }

    public function setSlug($slug){
        $this->slug = $slug;
        return $this;
    }

}

In my controller i make this to generate slug for old values in my datatable :

$filterBuilder = $this->get('doctrine.orm.entity_manager')>getRepository('DjooAppliBundle:Nomenclature')->createQueryBuilder('e')->orderBy('e.titre', 'asc');
$query = $filterBuilder->getQuery();
$nomenclatures = $query->getResult();

foreach($nomenclatures as $nomenclaturee){
    $nomenclature->setSlug(null);
    $this->get('doctrine.orm.entity_manager')->persist($nomenclature);
    $this->get('doctrine.orm.entity_manager')->flush();
 }

I have no error, but my old values are a null slug. I try to create a new element and i have a good slug. Have you and idea ?

Thanks

Answer 1

To change the slug you must change the related property. You can add a space at the end of $titre, save it, change it back and save it again. That will flush the slugs.

Answer 2

$uow = $em->getUnitOfWork();    
$uow->propertyChanged($entity, 'slug', NULL, NULL);    
$uow->scheduleForUpdate($entity);    
$em->flush();
