Symfony2 implement a form for OneToOne relation

Question

I am trying to implement a one to one relation. Each User can be affected at a building (Etablissement for me). A building can have many people but each people can be affected at one building at most.

I have this error :

ContextErrorException: Catchable Fatal Error: Argument 1 passed to Intranet\\UserBundle\\Entity\\User::setUserEtab() must be an instance of Intranet\\RhBundle\\Entity\\Etablissement, array given, called in C:\\wamp\\www\\projet\\vendor\\symfony\\symfony\\src\\Symfony\\Component\\PropertyAccess\\PropertyAccessor.php on line 360 and defined in C:\\wamp\\www\\projet\\src\\Intranet\\UserBundle\\Entity\\User.php line 322

The line 322 of User.php is :

public function setEtablissement(\Intranet\RhBundle\Entity\Etablissement $etablissement = null)

It occurs at the line $form->handleRequest($request); of my controller. This is my controller :

public function editerAction(Request $request, User $user){
    $form = $this->createForm(new EditerFormType, $user);
    if ($request->getMethod() == 'POST') {
        $form->handleRequest($request);
        die("ici");
        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $em->persist($user);
            $this->get('session')->getFlashBag()->add('success', "L'utilisateur ". $user->getNom() ." ". $user->getPrenom() . " a été édité avec succès !");
            $em->flush();
            return $this->redirect($this->generateUrl('intranet_rh_homepage'));
        }else
            $this->get('session')->getFlashBag()->add('danger', "Erreur de formulaire !");  
    }
    return $this->render('IntranetRhBundle:User:editer.html.twig',array('user' => $user, 'form' => $form->createView()));
}

The die doesn't work. Before adding the form, it was working.

This is the EditForm :

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('email', 'email', array('label' => 'form.email', 'translation_domain' => 'FOSUserBundle')) 
        ->add('nom', 'text')
        ->add('prenom', 'text')
        ->add('naissance','date',array(
        'widget' => 'single_text',
        'format' => 'dd/MM/yyyy',
        'attr' => array('class' => 'date', 'readonly' => 'readonly')
        ))
        ->add('sexe', 'choice', array(
         'choices' => array('Homme' => 'Homme', 'Femme' => 'Femme'),
         'multiple' => false
        ))
        ->add('etablissement', new UserEtabType())
    ;
}

public function setDefaultOptions(OptionsResolverInterface  $resolver)
{
    $resolver->setDefaults(array('data_class' => 'Intranet\Userbundle\Entity\User'));
}

This is my UserEtab form :

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
    ->add('etablissement', 'entity', array('class' => 'IntranetRhBundle:Etablissement', 'property' => 'nom', 'empty_value' => 'Aucun', 'empty_data'  => -1, 'required' => false))
    ;
}

And my relation on User entity :

    /**
* @ORM\OneToOne(targetEntity="Intranet\RhBundle\Entity\Etablissement", cascade={"persist", "remove"})
**/
private $etablissement;

The form's view is okay, there is a select list with all the building and an empty value. But when I post, I have this error I can't understand and solve.

I have the setter and getter if User entity :

    /**
 * Set Etablissement
 *
 * @param \Intranet\RhBundle\EntityEtablissement $etablissement
 * @return User
 */
public function setEtablissement(\Intranet\RhBundle\Entity\Etablissement $etablissement = null)
{
    $this->etablissement = $etablissement;

    return $this;
}

/**
 * Get Etablissement
 *
 * @return \Intranet\RhBundle\Entity\Etablissement 
 */
public function getEtablissement()
{
    return $this->etablissement;
}

But when I var_dump $request->get('user')->get('etablissement') it doesn't work :

Error: Call to undefined method Intranet\\UserBundle\\Entity\\User::get() in C:\\wamp\\www\\projet\\src\\Intranet\\RhBundle\\Controller\\UserController.php line 69

And the building doesn't appear in var_dump of $request->get('user') .

EDIT :

I don't have a setDefaultOptions method for my UserEtabType because I don't know what I have to do. I tried to implements it but I have this kind of error :

The form's view data is expected to be an instance of class Intranet\\UserBundle\\Entity\\User, but is an instance of class Proxies__CG__\\Intranet\\RhBundle\\Entity\\Etablissement. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms an instance of class Proxies__CG__\\Intranet\\RhBundle\\Entity\\Etablissement to an instance of Intranet\\UserBundle\\Entity\\User.

For the new UserEtabType :

namespace Intranet\UserBundle\Form\Type;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class UserEtabType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
    ->add('etablissement', 'entity', array('class' => 'IntranetRhBundle:Etablissement', 'property' => 'nom', 'empty_value' => 'Aucun', 'empty_data'  => -1, 'required' => false))
    ;
}

public function setDefaultOptions(OptionsResolverInterface  $resolver)
{
    $resolver->setDefaults(array('data_class' => 'Intranet\UserBundle\Entity\User'));
}

public function getName()
{
    return 'intranet_userbundle_useretablissementtype';
}
}

Answer 1

Can you show the new UserEtabType() class ?

EDIT 1 : Try putting this line :

->add('etablissement', 'entity', array('class' => 'IntranetRhBundle:Etablissement', 'property' => 'nom', 'empty_value' => 'Aucun', 'empty_data' => -1, 'required' => false));

in the main EditForm

EDIT 2 : plus be careful :

$resolver->setDefaults(array('data_class' => 'Intranet\UserBundle\Entity\User'));

must be

$resolver->setDefaults(array('data_class' => 'Intranet\UserBundle\Entity\Etablissement'));

in your UserEtabType() class

Answer 2

Are you getting this error when you try to insert a record ? Or before that. For your information, setUserEtab() in the User entity expects an object of Etablissement, because of the one-to-one relationship. Passing the value of an array is not sufficient. Try passing the object of Etablissement it self (the selected object after performing dql).

Hope this helps someone.

Cheers!
