问题
I'm trying to build app based on REST api ang AngularJS. I've been following this tutorial http://npmasters.com/2012/11/25/Symfony2-Rest-FOSRestBundle.html but have to change some details ( depreciated methods ) and right now when I post to create new entity I get 'This form should not contain extra fields' error.
class MainController extends Controller
{
public function indexAction(Request $request)
{
$form = $this->createForm(new TaskType(),null,array('action' => $this->generateUrl('post_tasks').'.json'))
->add('submit','submit');
$note_form = $this->createForm(new NoteType())
->add('submit','submit');
return $this->render('MyBundle:Main:index.html.twig',
array(
'form'=>$form->createView(),
'note_form'=>$note_form->createView(),
)
);
}
}
my TaskType form:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('timeStart','datetime',array(
'date_widget' => 'single_text',
'time_widget' => 'single_text',
'date_format' => 'yyyy-MM-dd',
'data' => new \DateTime('now')
))
->add('timeStop','datetime',array(
'date_widget' => 'single_text',
'time_widget' => 'single_text',
'date_format' => 'yyyy-MM-dd',
'data' => new \DateTime('now')
))
->add('project')
->add('descriptionTask')
->add('isCompleted',null,array('required' => false))
->add('isVisible',null,array('required' => false))
;
}
right now in my view I'm rendering only one form BUT I'M IN THE TEST STAGE:
{%extends 'MyBundle::layout.html.twig' %}
{%block content %}
<div ng-view></div>
{{ form(form) }}
{% endblock %}
AND this is the REST controller which is supposed to flush given entity:
public function cpostAction(Request $request)
{
$entity = new Task();
$form = $this->createForm(new TaskType(), $entity);
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($entity);
$em->flush();
return $this->redirectView(
$this->generateUrl(
'get_organisation',
array('id' => $entity->getId())
),
Codes::HTTP_CREATED
);
}
return array(
'form' => $form,
);
}
WEIRD THING: when I put the same code from REST controller to MainController, then form is validated and new entity is being flushed, but somehow REST controller throws error...
回答1:
Its because when you are generating the form you are adding submit buttons but when you are validating them you are not. try:
public function cpostAction(Request $request)
{
$entity = new Task();
$form = $this->createForm(new TaskType(), $entity)->add('submit','submit');
...
The submit button is technically a field even though symfony wont map it to an entity property by default. So when you generate the form with a submit button and then submit that form the form you generate in your validation controller action needs to also have a submit button.
回答2:
If you want the validator to ignore additional fields you should try passing 'allow_extra_fields' => true
as an option to the FormBuilder.
回答3:
If you wanna disable fields validation, you must add
public function setDefaultOptions(\Symfony\Component\OptionsResolver\OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'csrf_protection' => false,
'validation_groups' => false,
));
}
And in buildForm method:
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder->addEventListener(FormEvents::POST_SUBMIT, function ($event) {
$event->stopPropagation();
}, 900);
$builder->add('field1','text')
->add('field2','text')
.
.
.
}

回答4:
If you are adding a single SubmitType button or similar, you use the solution Chausser indicated
$entity = new Task();
$form = $this->createForm(new TaskType(), $entity)->add('submit','SubmitType::class');
However, in case you are using a CollectionType and embedding a set of sub forms, you need to include 'allow_add' => true in your parameters for that type. For example, in your EntityType form builder:
$builder->add('subEntities', CollectionType::class, array(
'entry_type' => SubEntityType::class,
'entry_options' => array('label' => false),
'allow_add' => true,
))
Make sure you do that for all levels of embedding if you have multiple levels.
