Symfony2.4 form 'This form should not contain extra fields' error
提问by mmmm
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.htmlbut 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.
我正在尝试基于 REST api 和 AngularJS 构建应用程序。我一直在关注本教程http://npmasters.com/2012/11/25/Symfony2-Rest-FOSRestBundle.html但必须更改一些细节（折旧方法），现在当我发布以创建新实体时，我得到“此表单不应包含额外字段”错误。
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:
我的 TaskType 表单：
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:
现在在我看来，我只渲染一种形式，但我正处于测试阶段：
{%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:
这是应该刷新给定实体的 REST 控制器：
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 validatedand new entity is being flushed, but somehow REST controller throws error...
奇怪的事情：当我将相同的代码从 REST 控制器放入 MainController 时，表单被验证并刷新新实体，但不知何故 REST 控制器抛出错误......

If you want the validator to ignore additional fields you should try passing 'allow_extra_fields' => trueas an option to the FormBuilder.
如果您希望验证器忽略其他字段，您应该尝试将其'allow_extra_fields' => true作为选项传递给 FormBuilder。

Its because when you are generating the form you are adding submit buttons but when you are validating them you are not. try:
这是因为当您生成表单时，您正在添加提交按钮，但当您验证它们时却没有。尝试：
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.
尽管默认情况下 symfony 不会将提交按钮映射到实体属性，但提交按钮在技术上是一个字段。因此，当您使用提交按钮生成表单然后提交该表单时，您在验证控制器操作中生成的表单也需要有一个提交按钮。

If you wanna disable fields validation, you must add
如果要禁用字段验证，则必须添加
public function setDefaultOptions(\Symfony\Component\OptionsResolver\OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'csrf_protection' => false,
'validation_groups' => false,
));
}
And in buildForm method:
在 buildForm 方法中：
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder->addEventListener(FormEvents::POST_SUBMIT, function ($event) {
$event->stopPropagation();
}, 900);
$builder->add('field1','text')
->add('field2','text')
.
.
.
}

If you are adding a single SubmitType button or similar, you use the solution Chausser indicated
如果您要添加单个 SubmitType 按钮或类似按钮，请使用 Chausser 指示的解决方案
$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:
但是，如果您使用 CollectionType 并嵌入一组子表单，则需要在该类型的参数中包含 'allow_add' => true 。例如，在您的 EntityType 表单构建器中：
$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.
如果您有多个级别，请确保对所有级别的嵌入都这样做。
