Reading this page I’ve setup a form to handle PATCH requests.
I’ve a Player entity:

Now I’ve created a player form class with the app/console and I’ve edited the team field to be an instance of the Team entity, this way:
<?php
namespace Acme\PlayerBundle\Form;
use Acme\TeamBundle\Entity\TeamRepository;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class PlayerType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
->add('shirtNumber')
->add('firstname')
->add('lastname')
->add('role')
->add('team', 'entity', array(
'class' => 'AcmeTeamBundle:Team',
'query_builder' => function(TeamRepository $er) {
$query = $er->createQueryBuilder('t');
return $query;
}
));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Acme\PlayerBundle\Entity\Player',
'csrf_protection' => false
));
}
public function getName()
{
return 'player';
}
}
And this is the relevant part of my controller:
/**
* Create a new player
*
* @Route(".{_format}", name="api_player_create")
* @Method("POST")
* @ApiDoc(
* description="Create a new player",
* statusCodes={
* 201="Player created and informations are returned",
* 400="Missing informations",
* 403="The user isn't authorized"
* },
* input="Acme\PlayerBundle\Form\PlayerType",
* return="Acme\PlayerBundle\Entity\Player"
* )
*
* @return Renders the player just created
*/
public function createPlayerAction()
{
return $this->processForm(new Player());
}
/**
* Edit a player
*
* @param integer $id The id of the player to be created
*
* @Route("/{id}.{_format}", name="api_player_patch", requirements={ "id": "\d+" })
* @Method("PATCH")
* @ApiDoc(

* 403="The user isn't authorized"
* },
* input="Acme\PlayerBundle\Form\PlayerType",
* return="Acme\PlayerBundle\Entity\Player"
* )
*
* @return Renders the player just edited
*/
public function editPlayerAction(Player $player)
{
if ($player->getOwner() != $this->getUser()) {
throw new ApiException\PermissionDeniedException;
}
return $this->processForm($player);
}
/**
* Function to handle a form to create/edit a player
*
* @param Player $player The player to be created or edited
*
* @return Api Response
*/
private function processForm(Player $player)
{
/**
* Check if the player is new (to be created) or we're editing a player
*/
$statusCode = is_null($player->getId()) ? 201 : 200;
$form = $this->createForm(new PlayerType(), $player);
$form->bind($this->getRequest());
if ($form->isValid()) {
if($player->getTeam()->getOwner() != $this->getUser()) {
throw new ApiException\PermissionDeniedException;
}
$player->setOwner($this->getUser());
$this->entityManager->persist($player);
$this->entityManager->flush();
return $this->apiResponse->getResponse($player, $statusCode);
}
return $this->apiResponse->getResponse($form, 400, 'Missing arguments');
}
The player creation works fine, the player edit doesn’t, when the user makes the api request, passing the ID in the url and the name of the player I get:
Catchable Fatal Error: Argument 1 passed to Acme\PlayerBundle\Entity\Player::setTeam() must be an instance of Acme\TeamBundle\Entity\Team, null given, called in /Volumes/Dati/Users/alessandro/Sites/acme-api/vendor/symfony/symfony/src/Symfony/Component/Form/Util/PropertyPath.php on line 538 and defined in /Volumes/Dati/Users/alessandro/Sites/acme-api/src/Acme/PlayerBundle/Entity/Player.php line 278
Seems that form is trying to set the Team to null, why?
I’ve tried both sending and not the team as the form parameters but it doesn’t work.
Any clue?
Figured it out that null unsent fields in the form is the default behaviour in symfony.
There is an open request for partial form binding in symfony. For now a guy created a form event subscriber that adds the missing fields with the actual values:
https://gist.github.com/3720535
This is his code:
to add to the form you have to edit the buildForm method in the form class:
In this case you’re ok to use the PATCH REST requests to edit an entity just by the sent fields
