Form validation does not show error messages

[marcoshoya]

Hi guys,

I'm trying submit a form to my controller but I can not get those errors messages from form.

According to docs (http://symfony.com/doc/current/bundles/FOSRestBundle/2-the-view-layer.html#forms-and-views), I should get

{
  "code": 400,
  "message": "Validation Failed";
  "errors": {
    "children": {
      "username": {
        "errors": [
          "This value should not be blank."
        ]
      }
    }
  }

However, my response is:

{
  "children": {
    "username": [],
  }
}

My config.yml

fos_rest:
    disable_csrf_role: IS_AUTHENTICATED_ANONYMOUSLY
    param_fetcher_listener: true
    # formato default caso não seja informado
    routing_loader:
        default_format: json
    view:
        # registra os mimi types permitidos no header da request
        mime_types: 
            json: ['application/json', 'application/json;version=1.0', 'application/json;version=1.1']
        view_response_listener: 'force'
        formats:
            xml:  true
            json: true
        templating_formats:
            html: true
    format_listener: true
    exception:
        codes:
            'Symfony\Component\Routing\Exception\ResourceNotFoundException': 404
            'Doctrine\ORM\OptimisticLockException': HTTP_CONFLICT
        messages:
            'Symfony\Component\Routing\Exception\ResourceNotFoundException': true
    allowed_methods_listener: true
    access_denied_listener:
        json: true
    body_listener: true

My controller:

<?php

namespace AppBundle\Controller;

use Nelmio\ApiDocBundle\Annotation\ApiDoc;
use FOS\RestBundle\Controller\FOSRestController;
use FOS\RestBundle\Controller\Annotations as Rest;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Validator\Constraints as Assert;

class SecurityController extends FOSRestController
{

    /**
     * Auth
     *
     * @ApiDoc(
     *  resource=true,
     *  description="Do the authentication",
     *  parameters={
     *      {"name"="username", "dataType"="string", "required"=true, "description"="username from user"}
     *  },
     *  statusCodes={
     *      200="Returned when successful"
     *  }
     * )
     *
     * @Rest\Post()
     * @Rest\View()
     */
    public function authAction(Request $request)
    {
        $form = $this->createFormBuilder()
                ->add('username', 'text', array('constraints' => new Assert\NotBlank()))
                ->getForm();

        $form->handleRequest($request);
        if ($form->isValid()) {
            // do something
        }

        return $form;

    }

}

What I am doing wrong???

Thanks in advance

Update: I've tried the solution here (#738 (comment)) and It's works.

I also tried

$form->submit(array(
            'username' => $request->get('username')
        )); 

Anyway, I guess it must be a better way to validate input data...

Thanks

I had same issue. But it's strange as official symfony documentation suggest only using handleRequest() method because submit() is deprecated. http://symfony.com/doc/current/cookbook/form/direct_submit.html#cookbook-form-call-submit-directly

[Davidmattei]

@sepikas-antanas : I think using the request object as a input parameter for the submit function is deprecated, not the function itself ?

[GuilhemN]

Do you use the jmsserializer or the symfony serializer?

And submit is not deprecated as @sepikas-antanas said only passing Request as an attribute.

I got exactly the same issue and I'm using jmsserializer, any idea of where it might come from ?

You should return

$view = $this->view($form->getErrors(true));
return $this->handleView($view);

i solved it like this:

    $user = new User;
    $form = $this->createForm(UserType::class, $user);
    $view = View::create();

    $form->submit($request->request->all());
    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();

        $em->persist($user);
        $em->flush();

        $view->setData($form->getData());
    } else {
        $view->setData($form);
    }

    return $this->handleView($view);

Don't forget to disable CSRF validation (https://symfony.com/doc/master/bundles/FOSRestBundle/2-the-view-layer.html#csrf-validation)

fos_rest:
    disable_csrf_role: ROLE_API
    #disable_csrf_role: IS_AUTHENTICATED_ANONYMOUSLY #just for testing
