Select categories related to current Store entity - php

Question

I have two entities Store and Category and each Store has it's own categories.
I'd like that when a Store owner's try to add a new category and category_parent, just the categories related to current Store will be displayed.
Right now, all categories are displayed in the select-option.
I'm using Tree Gedmo extension to manage Category entity and I use getChildrenQueryBuilder method to select categories.
How can I modify this method and add my specific constraint ?
$store which is the constraint is declared in the controller action down.
I'd like te set current Category option disabled when he try to add a category_parent, so category and category parent must be differnt.
I hope it's clear

}
I managed to pass the parameter $store to the form, but I don't know how to use it as a constraint in getChildrenQueryBuilder method.
Should I create a new custom method? I prefer to use getChildrenQueryBuilder if it is possible.
Here is the new code
CategoryType.php
class CategoryType extends AbstractType
{
private $store;
public function __construct($store)
{
$this->store = $store;
}
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$store = $this->store;
$builder
//...........
//...........
->add('parent', 'entity', array(
'required' => false,
'label' => 'Category parent',
'class' => 'ProjectStoreBundle:Category',
'attr' => array('class' => 'col-sm-8'),
'empty_value' => 'Select one category',
'property' => 'indentedName',
'multiple' => false,
'expanded' => false ,
'query_builder' => function (\Project\StoreBundle\Entity\CategoryRepository $r) use ($store)
{
return $r->getChildrenQueryBuilder(null, null, 'root', 'asc', false);
}
))
;
}
/**

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Project\StoreBundle\Entity\Category'
));
}
/**
* #return string
*/
public function getName()
{
return 'project_storebundle_category';
}
}
Controller
/**
* #ParamConverter("store", options={"mapping": {"store_id":"id"}})
*/
public function newAction(Store $store)
{
// keep in mind, this will call all registered security voters
if (false === $this->get('security.context')->isGranted('edit', $store)) {
throw new AccessDeniedException('Unauthorised access!');
}
$category = new Category();
$category->setStore($store);
$category->setUniqueBase($store->getId());
$form = $this->createForm(new CategoryType($store), $category);
$request = $this->getRequest();
if ($request->getMethod() == 'POST')
{
$form->bind($request);
if ($form->isValid())
{
$em = $this->getDoctrine()->getManager();
$em->persist($category);
$em->flush();
$this->get('session')->getFlashBag()->add('message', 'Category enregistred');
return $this->redirect( $this->generateUrl('dashboard_category_index', array('store_id' => $store->getId())));

You're not saying which Symfony2 version you're using, but generically speaking, you just need to find a way to pass the current store to your form builder and use it in the method that filters the possible categories.
Take a look at this one, or this one, basically you just need to inject the $store into your form builder, and then you (almost) have it :-)
