FOSRest Symfony POST using json - json

Question

I'm new with the symfony framework. I'm trying to create webservices with FOSRest bundle but I had a problems when I tried to implement the POST method for one entity with json.
Test:
public function testJsonPostNewTesteAction(){
$this->client->request(
'POST',
'/api/teste/new',
array(),
array(),
array(
'Content-Type' => 'application/json',
'Accept' => 'application/json'
),
'{"Teste":{"title":"O teu title"}}'
);
$response = $this->client->getResponse();
$this->assertJsonResponse($response, Codes::HTTP_CREATED);
}
Controller:
/**
*
* #Config\Route(
* "/teste/new",
* name="postTestNew"
* )
* #Config\Method({"POST"})
*
* #param Request $request the request object
*
* #return View|Response
*/
public function postNewTeste(Request $request){
return $this->processFormTest($request);
}
/**
* Method for create the process form to Advertisements
*
* #param Request $request
*
* #return mixed
*/
private function processFormTest(Request $request){
$form = $this->createForm(
new TesteType(),
new Teste()
);
$form->bind($request);
//$from->handleRequest($request);
if ($form->isValid()) {
$test = $form->getData();
return $test;
}
return View::create($form, Codes::HTTP_BAD_REQUEST);
}
The problem is when I use the handleRequest(), the method isValid() returns false because the form didn't submit. So I try to change the handleRequest to the bind method. In the last case, the method isValid() returns true but the method getData() returns a null object.
I don't know if the problem is the type form class bellow.
Type Form:
/**
* The constant name to that type
*/
const TYPE_NAME = "Teste";
/**
* {#inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options){
parent::buildForm($builder, $options);
$builder->add("title", ValidationType::TEXT);
}
/**
* {#inheritdoc}
*/
public function setDefaultOptions(OptionsResolverInterface $resolver){
$resolver->setDefaults(
array(
'csrf_protection' => false,
'cascade_validation' => true,
'data_class' => 'oTeuGato\DatabaseBundle\Entity\Teste'
)
);
}
/**
* Returns the name of this type.
*
* #return string The name of this type
*/
public function getName(){
return AdvertisementType::TYPE_NAME;
}
I need to POST the entity with both ways. Anyone sugest anything for my problem?
Thanks for the patience!

Answer 1

Got the same issue with the form binding, the only way i found to solve it was to set an empty string to the form getName function:
/**
* Returns the name of this type.
*
* #return string The name of this type
*/
public function getName(){
return '';
}
And i would suggest to use the handleRequest method when you bind your data because the bind method is deprecated:
private function processFormTest(Request $request){
$form = $this->createForm(
new TesteType(),
new Teste()
);
$from->handleRequest($request);
if ($form->isValid()) {
$test = $form->getData();
return $test;
}
return View::create($form, Codes::HTTP_BAD_REQUEST);
}
It looks more like a hack but seems like it's the only way for now:

I am not entirely sure but I think it's because you're sending the data with: 'Content-Type' => 'application/json'
in stead of 'Content-Type' => 'application/x-www-form-urlencoded'
Or at least I think that's the reason why the handleRequest is not doing it's thing.
