Symfony2 参数与嵌入形式

Question

EDIT : I find the real problem!

I am trying to give a paramEter to a sub-form from the controller. Without this parameter, the form is working perfectly.

I want to show in the select list only users which are not already present in the relation. I have this query_builder:

'query_builder' => function(UserRepository $er) use($options) {
                                    return $er->getFormateursAvailable($options['categ']);
                               },

And the method:

public function setDefaultOptions(OptionsResolverInterface  $resolver)
{
    $resolver->setDefaults(array('data_class' => 'Intranet\FormationBundle\Entity\CategorieFormateur', 'categ' => false));
    //$resolver->setDefaults(array('data_class' => 'Intranet\FormationBundle\Entity\CategorieFormateur'));
}

For the collection form, so, I have to put this option in the form:

'options' => $options,

But I don't know if it is true, and I have to define the method:

public function setDefaultOptions(OptionsResolverInterface  $resolver)
{
    $resolver->setDefaults(array('categ' => false));
}

(The form is working without this method if there is no parameter.) And calling:

$form = $this->createForm(new GererFormateurCategorieType(), $categorie, array('categ' => $categorie));

And then, I have this error:

Neither the property "user" nor one of the methods "getUser()", "isUser()", "hasUser()", "__get()" exist and have public access in class "Intranet\\FormationBundle\\Entity\\Categorie".

The relation:

Categorie has this property:

/**
* @ORM\OneToMany(targetEntity="Intranet\FormationBundle\Entity\CategorieFormateur", mappedBy="categorie", cascade={"persist", "remove"}, orphanRemoval=true)
**/
private $formateurs;

With addFormateur, removeFormateur and getFormateurs

CategorieFormateur :

    /**
* @ORM\Id
* @ORM\ManyToOne(targetEntity="Intranet\FormationBundle\Entity\Categorie", inversedBy="formateurs")
* @ORM\JoinColumn(name="categorie_id", referencedColumnName="id")
*/
private $categorie;

/**
* @ORM\Id
* @ORM\ManyToOne(targetEntity="Intranet\UserBundle\Entity\User")
* @ORM\JoinColumn(name="user_id", referencedColumnName="id")
*/
private $user;

with setters and getters for each properties.

Answer 1

According to the error message, you have to add the setFormateurs() method in your Categorie entity:

public function setFormateurs($formateurs)
{
    $this->formateurs = $formateurs;

    return $this;
}

I found an alternative method, wich is not the true answer :

In the repository, I use $request = Request::createFromGlobals();

And I explode the $requestPathInfo() to get the last parameter and I use it in the query...

But the existing users in the relation are not loaded altough they not appers in the list.

I hope somebody knows how to do that properly !
