FOSRestBundle - PATCH not working as should

Question

I want to update entity with 'PATCH' method (update only those fields which have been submitted).

  /* Edit an existing Content entity.
  *
  * @Rest\Patch(
  *     "/{content}.{_format}",
  *     requirements={"content" = "\d+"},
  *     defaults = { "_format" = "json" }
  * )
  *
  * @Rest\View(serializerGroups={"user""admin"})
  * @param Content $content
  * @return View
  * @throws \NotFoundHttpException*
  *
  * @ApiDoc(
  *  resource="/api/content/",
  *  description="Updates content data",
  *
  *  input="ContentBundle\Form\ContentType",
  *
  *  output={
  *   "class"="EntriesBundle\Entity\Content",
  *   "parsers"={"Nelmio\ApiDocBundle\Parser\JmsMetadataParser"},
  *   "groups"={"user","admin"}
  *  }
  * )
  */
 public function editAction(Request $request, Content $content)
 {
     if (!$content) {
         throw $this-createNotFoundException();
     }

     $editForm = $this-createForm('ContentBundle\Form\ContentType', $content);
     $editForm-submit($request-request-get($editForm-getName()));

     $view = View::create()
         -setSerializationContext(SerializationContext::create()-setGroups(['user']));

     if ($editForm-isSubmitted() && $editForm-isValid()) {
         $em = $this-getDoctrine()-getManager();
         $em-persist($content);
         $em-flush();

         $view
             -setStatusCode(Codes::HTTP_OK)
             -setTemplate("ContentBundle:content:show.html.twig")
             -setTemplateVar('contents')
             -setData($content);

     } else {
         $view
             -setStatusCode(Codes::HTTP_BAD_REQUEST)
             -setTemplateVar('error')
             -setData($editForm)
             -setTemplateData(['message' = $editForm-getErrors(true)])
             -setTemplate('ContentBundle:content:show.html.twig');
     }

     return $this-get('fos_rest.view_handler')-handle($view);
 }

Form:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('title', TextType::class)
        ->add('description', TextareaType::class)
        ->add('eng', CheckboxType::class, [
            'required' => false
        ]);
}

I have entity with 'eng' set to TRUE. If I run query to update only title field, eng changes to false. and description to null. Any ideas why?

I've got it to works.

Remember folks that if you want to use PATCH method you need to use TextType instead of ChoiceType in your form:

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('title', TextType::class)
            ->add('description', TextareaType::class)
            ->add('eng', TextType::class);
    }
