Symfony2 implement a form for OneToOne relation - php

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!
