Symfony2 - Form validation with query builder - value never valid - forms

Question

I have two entities "meeting" and "Slot" with a one2many relation.
I have a form to update a meeting (just to change the time slot), i want to display only free slot so i've made a query_ builder. It works for the creation, but for the update, there is always a validation error (this value is not valid).
This is my code :
controller
public function editAction($id)
{
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('NfidBusinessMeetingBundle:Meeting')->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find Meeting entity.');
}
$editForm = $this->createForm(new UpdateMeetingType($entity->getUserA(),$entity->getUserB()), $entity);
if ($this->getRequest()->isMethod('POST')) {
$editForm->bind($this->getRequest());
// var_dump($editForm->getData() );
if ($editForm->isValid()) {
$entity->setDeleted(0);
$entity->setPending(1);
$entity->setValidated(0);
$em->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('meeting_front'));
}
}
return $this->render('NfidBusinessMeetingBundle:MeetingFront:edit.html.twig', array(
'entity' => $entity,
'edit_form' => $editForm->createView(),
));
}
form builder
public function __construct($userA = null, $userB = null)
{
$this->userA = $userA;
$this->userB = $userB;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
// die(var_dump($options));
$users[] = $this->userA;
$users[] = $this->userB;
$builder
->add('slot', 'entity',
array(
'class' => 'NfidBusinessMeetingBundle:Slot',
'query_builder' => function(SlotRepository $cr) use ($users) {
return $cr->findAllFreeSlotByUsers($users);
}
)
);
}
Repository
public function findAllFreeSlotByUsers(array $users){
$subquery = $this->createQueryBuilder('query1');
$subquery->select('s')
->from('NfidBusinessMeetingBundle:Meeting', 'm')
->leftJoin('m.slot', 's')
->leftJoin('m.userA', 'uA')
->leftJoin('m.userB', 'uB')
->where('m.userA = :userA')
->orWhere('m.userA = :userB')
->orWhere('m.userB = :userA')
->orWhere('m.userB = :userB')
->andWhere('m.validated = 1');
$query = $this->createQueryBuilder('query');
$query->select('s2')
->from('NfidBusinessMeetingBundle:Slot', 's2')
->where($query->expr()->notIn('s2.id', $subquery->getDQL()))
->setParameters(array('userA' => $users[0]->getId(), 'userB' => $users[1]->getId()));
return $query;
}
Someone can help me ?
EDIT : If made this it works
public function buildForm(FormBuilderInterface $builder, array $options)
{
// die(var_dump($options));
$users[] = $this->userA;
$users[] = $this->userB;
$builder
->add('slot');
}
=========================== EDIT ====================================
I've try this
public function findAllFreeSlotByUsers(array $users){
$subquery = $this->createQueryBuilder('query1');
$subquery->select('s')
->from('NfidBusinessMeetingBundle:Meeting', 'm')
->leftJoin('m.slot', 's')
->leftJoin('m.userA', 'uA')
->leftJoin('m.userB', 'uB')
->where('m.userA = :userA')
->orWhere('m.userA = :userB')
->orWhere('m.userB = :userA')
->orWhere('m.userB = :userB')
->andWhere('m.validated = 1');
$query = $this->createQueryBuilder('query');
$query->select('s2')
->from('NfidBusinessMeetingBundle:Slot', 's2')
->where(
$query->expr()->orx(
$query->expr()->notIn('s2.id', $subquery->getDQL()),
$query->expr()->eq('s2.id', $users[2]->getId())
)
)
->setParameters(array('userA' => $users[0]->getId(), 'userB' => $users[1]->getId()));
return $query;
}
and
public function buildForm(FormBuilderInterface $builder, array $options)
{
// die(var_dump($options));
$users[] = $this->userA;
$users[] = $this->userB;
$users[] = $builder->getData();
if ($this->userConnected == User::TYPE_RESSOURCE ) {
$builder
->add('slot', 'entity',
array(
'class' => 'NfidBusinessMeetingBundle:Slot',
'query_builder' => function(SlotRepository $cr) use ($users) {
return $cr->findAllFreeSlotByUsers($users);
}
)
)
And it's always the same error
string 'slot:
ERROR: Cette valeur n'est pas valide.

UPDATED:
Insert this code and output the result:
editAction:
var_dump($entity->getSlot()->getId());
$editForm = $this->createForm(new UpdateMeetingType($entity->getUserA(),$entity->getUserB()), $entity);
buildForm:
'query_builder' => function(SlotRepository $cr) use ($users) {
$query = $cr->findAllFreeSlotByUsers($users);
$results = $query->getQuery()->getResult();
foreach ($results as $result) {
var_dump($result->getId());
}
die;
}
Try this:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$data = $builder->getData();
$users[] = $this->userA;
$users[] = $this->userB;
$builder
->add('slot', 'entity',
array(
'class' => 'NfidBusinessMeetingBundle:Slot',
'query_builder' => function(SlotRepository $cr) use ($users) {
return $cr->findAllFreeSlotByUsers($users, $data->getSlot());
}
)
);
}
SlotRepository: slot_id is the second parameters you pass from the entity type
$query = $this->createQueryBuilder('query');
$query->select('s2')
->from('NfidBusinessMeetingBundle:Slot', 's2')
->where(
$query->expr()->orx(
$query->expr()->notIn('s2.id', $subquery->getDQL()),
$query->expr()->eq('s2.id', $slot_id)
)
)
->setParameters(array('userA' => $users[0]->getId(), 'userB' => users[1]->getId()));
Of course, you may need to make some tests if the slot is null, etc.
What may be your issue:
Let's assume NEW meeting. This a the list of free slots:
Slot 1,
Slot 2,
Slot 3,
You select Slot 2. At edit, because it is used this is the list of free slots:
Slot 1,
Slot 3
Since Slot 2 is not on the list you get invalid choice.
