Symfony 2 set default values on collection field entities - symfony

Question

I've these 2 forms:
Lineups form which edits the lineups field of a match entity
<?php
namespace Acme\MatchBundle\Form\Type;
use Acme\UserBundle\Entity\UserRepository;
use Acme\TeamBundle\Entity\TeamRepository;
use Acme\ApiBundle\Listener\PatchSubscriber;
use Acme\CoreBundle\Form\DataTransformer\TimestampToDateTimeTransformer;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class LineupsType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('lineups', 'collection', array(
'type' => new LineupType(),
'allow_add' => true,
'allow_delete' => false
))
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Acme\MatchBundle\Entity\Match',
'csrf_protection' => false
));
}
public function getName()
{
return 'match';
}
}
Lineup form which creates/edits a lineup entity
<?php
namespace Acme\MatchBundle\Form\Type;
use Acme\PlayerBundle\Entity\PlayerRepository;
use Acme\ApiBundle\Listener\PatchSubscriber;
use Acme\CoreBundle\Form\DataTransformer\TimestampToDateTimeTransformer;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class LineupType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('player', 'entity', array(
'class' => 'AcmePlayerBundle:Player',
'property' => 'id',
'query_builder' => function(PlayerRepository $er) {
$query = $er->createQueryBuilder('p');
return $query;
}
))
->add('status', 'text')
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Acme\MatchBundle\Entity\Lineup',
'csrf_protection' => false
));
}
public function getName()
{
return 'match';
}
}
Lineup entity fields
/**
* #var Match $match
*
* #ORM\ManyToOne(targetEntity="Match", inversedBy="lineups")
* #Assert\NotBlank()
*/
private $match;
/**
* #var \Acme\PlayerBundle\Entity\Player $player
*
* #ORM\ManyToOne(targetEntity="Acme\PlayerBundle\Entity\Player", inversedBy="lineups")
* #Assert\NotBlank()
*/
private $player;
/**
* #var string
*
* #ORM\Column(name="status", type="string", length=16)
* #Assert\NotBlank()
*/
private $status;
Now I've successfully got to add/remove Lineup entities to the lineups field, what I want is to set the $match field of lineup entity to the match edited with the lineups form.
Is that possible?

Answer 1

Found by myself that binding to the BIND form event let me do what I've needed:
$builder->addEventListener(
FormEvents::BIND,
function (FormEvent $event) {
$data = $event->getData();
$lineups = $data->getLineups();
foreach ($lineups as &$lineup) {
$lineup->setMatch($data);
}
$event->setData($data);
}
);
Which works fine ;)
