Symfony \ Component \ Form \ Exception \ TransformationFailedException

Question

Kullanıcı için seçme seçeneğini doldurmak için ajax çağrısı kurmaya çalışıyorum.

3/Doğrulama formu

Unable to reverse value for property path "zone": 

The choice "13e Arrondissement" does not exist or is not unique 

FormType geçmez:

1/Sen gayet güzel dek bölge görünür

Her şey iş konumunuzu

2/yeni açılan belirleyin:

public function buildForm(FormBuilderInterface $builder, array $options) 
{ 
    //... 

    ->add('location', EntityType::class, ['class' => 'PagesBundle:City']) 
    ->add('zone', CoreType\ChoiceType::class, ['choices_as_values' => true, 'mapped' => false]); 

    $builder->get('zone')->addEventListener(FormEvents::PRE_SET_DATA, function (FormEvent $event) { 
      $form = $event->getForm()->getParent(); 
      $data = $event->getData(); 
      $city[$data] = $data; 

      $form->add('zone', CoreType\ChoiceType::class, ['choices' => $city,'choices_as_values' => true]); 

     //...  

Benim Ajax:

$("document").ready(function() { 
$('#zone').addClass('uk-hidden'); 
$("#cityName").change(function() { 
    var city = $("#owner_location option:selected").text(); 

     $.ajax({ 
      type: 'GET', 
      url: 'http://locavip.dev/app_dev.php/owner/city/' + city, 

      beforeSend: function(){ 
      $('#owner_zone option').remove(); 
      }, 

      success: function(data) { 

      $.each(data.zone, function(index, value){ 
       $('#zone').removeClass('uk-hidden'); 
       $("#owner_zone").append($('<option>', { value : value, text: value })); 
      }); 
      } 
     }); 

}); });

AjaxController: Ben çözüm bulduk

Answer 1

$em = $this->getDoctrine()->getManager(); 
     $database = 'PagesBundle:'.$city; 
     $cityName = $em->getRepository($database)->findAll(); 

     foreach ($cityName as $value) { 
       $cities[] = $value->getZone(); 
     } 
     $response = new JsonResponse(); 

     return $response->setData(array('zone' => $cities)); 

teşekkürler.

Ajax alanımda "ZONE" için önce ChoiceType :: class'ı kullanıyorum, sonra PRE_SUBMIT üzerinde "ZONE" kullanıcı verilerini alıyorum ve alanımı TextType :: class olarak değiştirdim, sonra "getData()" seçeneğini kullanıyorum DB'ye eklemeden önce doğru verileri ayarlamak için.

public function buildForm(FormBuilderInterface $builder, array $options)
