Installing Doctrine extensions in a Symfony 2 project causes Fatal Error

Question

Here is the problem : I don't succeed to install doctrine extensions with symphony 2, especially timestampable. I follow this tutorial

How I proceed :

I add this lines in deps file :

[gedmo-doctrine-extensions]
   git=http://github.com/l3pp4rd/DoctrineExtensions.git

[Stof-DoctrineExtensionsBundle]
   git=https://github.com/stof/StofDoctrineExtensionsBundle.git
   target=/bundles/Stof/DoctrineExtensionsBundle

Then I enter the line

./bin/vendors install --reinstall

All is fine.

Then I activate extensions in concerned files

# config.yml
stof_doctrine_extensions:
    default_locale: fr_FR
    orm:
        default:
            timestampable: true


# AppKernel.php    
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            [...]
            new Stof\DoctrineExtensionsBundle\StofDoctrineExtensionsBundle(),
            [...]
        );

# autoload.php
use Symfony\Component\ClassLoader\UniversalClassLoader;
use Doctrine\Common\Annotations\AnnotationRegistry;

$loader = new UniversalClassLoader();
$loader->registerNamespaces(array(
    'Gedmo'            => __DIR__.'/../vendor/gedmo-doctrine-extensions/lib',
    'Stof'             => __DIR__.'/../vendor/bundles', 
    [...]
    ));

At last, I add annotate my entity

/**
 * @var datetime $updatedAt
 *
 * @ORM\Column(name="updated_at", type="datetime")
 * @Gedmo:Timestampable(on="update")
 */
private $updatedAt;

But I have this error :

Fatal error: Class 'Gedmo\Timestampable\TimestampableListener' not found in /Symfony/app/cache/dev/appDevDebugProjectContainer.php on line 203

What do I do wrong ?

Answer 1

Using @Gedmo\Timestampable(on="update") and putting the right path when registering the namespace seems to solve the problem.
