Symfony2 form query_builder with parameter

Question

I have this error :

"Catchable Fatal Error: Argument 1 passed to Intranet\RhBundle\Form\AvatarFormType::Intranet\RhBundle\Form{closure}() must be an instance of Intranet\UserBundle\Entity\ImageRepository, instance of Doctrine\ORM\EntityRepository given, called in C:\wamp\www\projet\vendor\symfony\symfony\src\Symfony\Bridge\Doctrine\Form\ChoiceList\ORMQueryBuilderLoader.php on line 56 and defined in C:\wamp\www\projet\src\Intranet\RhBundle\Form\AvatarFormType.php line 24"

When I began to search, I found a common error on the method in the repository. But maybe it's okay...

This is my ImageRepository :

public function getImageUser(User $user)
{
    $qb = $this->createQueryBuilder('i')
           ->where('i.user = :user ')
           ->setParameter('user', $user);

// Et on retourne simplement le QueryBuilder, et non la Query
return $qb;

}

This is my AvatarFormType:

/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    //die(var_dump($options['data']));
    $builder
       ->add('avatar', 'entity', array(
            'class' => 'IntranetUserBundle:Image',
            'property' => 'alt',
           'query_builder' => function(ImageRepository  $r) use($options) {
                return $r->getImageUser($options['user']);}
            )
        );
}

The relation :

/**
 * @ORM\OneToOne(targetEntity="Intranet\UserBundle\Entity\Image", cascade={"persist", "remove"})
 * @Assert\Valid()
 */
private $avatar;

And this is my controller :

public function imagesDeAction(Request $request, User $user) {
    $form = $this->createForm(new AvatarFormType(), $user, array('user' => $user));
    $images = $this->getDoctrine()
    ->getRepository('IntranetUserBundle:Image')
    ->findByUser($user);
    if ($request->getMethod() == 'POST') {
        $form->handleRequest($request);
        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $user->setAvatar($request->avatar);;
            $em->persist($user);
            $em->flush();
        }

    }
    $avatar = $user->getAvatar();
   return $this->render('IntranetRhBundle:Image:imagesDe.html.twig',array('user' => $user,'images' => $images, 'form' => $form->createView()));
}

Users have some pictures in there private directory and I want to choose an avatar. There is already a ManyToMany relation between User and Image and a OneToOne (as I noticed) between User and Image.

I'm trying to build a select list with only the pcitures of a specific user with the parameter. None of the solution I found is efficient to solve this error.

I'm not sure I have to call my function with use($options) and $options['data'] but with a var_dump I saw my User on $options['data'].

EDIT :

I bring a little precision : The ImageReposiroty seems to be not found although the use is ok. I don't have the error message "class not found". But if I put EntityReposirtoy the bug disappears and I have this symfony error message :

Expected argument of type "Doctrine\ORM\QueryBuilder", "array" given

But I know I have to call ImageRepository and not EntityRepository...

Ok basic problem is the form expecting the ImageRepository entity from you, but you are giving EntityRepository to it. Do you have any any data_class option? — Canser Yanbakan
I have this, nothing else : /** * @param OptionsResolverInterface $resolver */ public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'Intranet\UserBundle\Entity\Image' )); } — Deynis

Thank's to @R. Canser Yanbakan who gave me an example, I solve myself my problem !

In my entity I have * @ORM\Entity But for using reposiroty I have to call it like this :

* @ORM\Entity(repositoryClass="Intranet\UserBundle\Entity\ImageRepository")

The correct BuildForm is :

 /**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
       ->add('avatar', 'entity', array(
            'class' => 'IntranetUserBundle:Image',
            'property' => 'alt' ,
            'query_builder' => function(ImageRepository  $r) use($options) {
                                return $r->getImagesUser($options['user']);}
            )
        );
}

And the rigth createForm is :

$form = $this->createForm(new AvatarFormType(), $user, array('user' => $user));

$user to select the user's avatar, and the array for the parameter given at the query_builder
