因此,进入排除故障的第5天仍然无法解决问题。我甚至创建了一个特殊的表格,只是为了解决这个问题,仍然没有取得任何进展。基本问题:我有一个通过FormBuilderInterface使用表单修饰符构建的Symfony2表单,根据用户对表单中第一个实体的选择动态填充字段。表单中还有3个集合(表示与表单主要类的一对一关联)。
无论我做什么,在if ($form->isValid())
我都会得到非常熟悉和有趣的错误"错误:此表单不应包含额外的字段。"表单提交错误(3次,每个集合1次)。
值得注意并且可能与修复程序有关:如果我从表单中删除集合实体,它会正确验证。对于表单中的任何集合,或3个集合中的2个集合的任意组合(我已尝试全部),它会抛出"此表单不应包含额外字段"错误。
以下是表单类型的代码:
class ThisDataClassType extends AbstractType
{
protected $user_id;
public function __construct($user_id) {
$this->user_id = $user_id;
}
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$user_id = $this->user_id;
$builder->add('firstChoice', 'entity', array(
'class' => 'MyBundle:FirstChoice',
'query_builder' => function(firstChoiceRepository $repository) use ($user_id) {
return $repository->createQueryBuilder('f')
->where('f.user = ?1')
->andWhere('f.isActive = 1')
->setParameter(1, $user_id);
},
'property' => 'firstChoice_name',
'required' => true,
'mapped' => false,
'label' => 'block.firstChoice.name'
))
->add('sub_block_name','text', array(
'label' => 'subblock.block.name',
'max_length' => 50,
'required' => true,
'attr' => array(
'placeholder' => 'subblock.phv.name',
'pattern' => 'alpha_numeric'
)
))
// ... bunch of other standard form types (text, etc.) ... //
->add('subdata1', 'collection', array(
'type' => new SubData1Type()
))
->add('subdata2', 'collection', array(
'type' => new SubData2Type()
))
->add('subdata3', 'collection', array(
'type' => new SubData3Type()
));
$formModifier = function(FormInterface $form, $firstChoice_id) {
$form->add('secondChoice', 'entity', array(
'class' => 'MyBundle:SecondChoice',
'query_builder' => function(secondChoiceRepository $S_repository) use ($firstChoice_id) {
return $S_repository->createQueryBuilder('s')
->where('s.firstChoice_id = ?1')
->andWhere('s.isActive = 1')
->setParameter(1, $firstChoice_id);
},
'property' => 'secondChoice_name',
'label' => 'block.secondChoice.name'
));
};
$builder->addEventListener(
FormEvents::PRE_SET_DATA,
function(FormEvent $event) use ($formModifier) {
$data = $event->getData()->getId();
$formModifier($event->getForm(), $data);
}
);
$builder->get('firstChoice')->addEventListener(
FormEvents::POST_SUBMIT,
function(FormEvent $event) use ($formModifier) {
$data = $event->getForm()->getData();
$formModifier($event->getForm()->getParent(), $data->getId());
}
);
$builder->setMethod('POST');
}
/**
* @param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'MyBundle\Entity\ThisDataClass',
'user_id' => null,
'translation_domain' => 'block',
'cascade_validation' => true
));
}
/**
* @return string
*/
public function getName()
{
return 'ThisDataForm';
}
}
...和基本控制器(此刻仅用于测试):
public function TestFormAction(Request $request, $whichSize)
{
$user_id = $this->getUser()->getId();
$success = 'Not submitted';
$dataclass = new Entity\ThisDataClass();
$subdata1 = new Entity\SubData1();
$subdata2 = new Entity\SubData2();
$subdata3 = new Entity\SubData3();
if (!$request->isMethod('POST')) {
$dataclass->getSubData1()->add($subdata1);
$dataclass->getSubData2()->add($subdata2);
$dataclass->getSubData3()->add($subdata3);
}
$form = $this->createForm(new Form\ThisDataClassType($user_id), $dataclass, array(
'action' => $this->generateUrl('my_custom_test_route', array('whichSize' => $whichSize)),
'user_id' => $user_id
));
$form->handleRequest($request);
if ($form->isValid()) {
$success = 'Success!!';
return $this->render('MyBundle:DataClassTestForm.html.twig', array('dataClassTestForm' => $form->createView(), 'whichSize' => $whichSize, 'success' => $success));
} else {
$success = $form->getErrorsAsString();
}
return $this->render('MyBundle:DataClassTestForm.html.twig', array('dataClassTestForm' => $form->createView(), 'whichSize' => $whichSize, 'success' => $success));
}
提及其他几点:
'mapped' => false
设置的firstChoice字段外,以及
CSRF _token,但是我明确启用CSRF _token时会收到错误
或不,并且当我删除集合时,错误消失了)非常感谢任何人对我失踪的东西的洞察力。
答案 0 :(得分:8)
在休息了一天半之后,当我坐下来时,答案突然显现。所写的控制器仅在首次创建时将子数据类添加到表单中(即,当没有发生提交/ POST事件时)。因此,在提交事件之后创建的表单包含所有发布数据,但类与之无关。控制器现在已经被重写如下,表单现在按预期验证:
public function TestFormAction(Request $request, $whichSize)
{
$user_id = $this->getUser()->getId();
$success = 'Not submitted';
$dataclass = new Entity\ThisDataClass();
$subdata1 = new Entity\SubData1();
$subdata2 = new Entity\SubData2();
$subdata3 = new Entity\SubData3();
$dataclass->getSubData1()->add($subdata1);
$dataclass->getSubData2()->add($subdata2);
$dataclass->getSubData3()->add($subdata3);
$form = $this->createForm(new Form\ThisDataClassType($user_id), $dataclass, array(
'action' => $this->generateUrl('my_custom_test_route', array('whichSize' => $whichSize)),
'user_id' => $user_id
));
$form->handleRequest($request);
if ($form->isValid()) {
$success = 'Success!!';
} else {
$success = 'Invalid!!';
}
} // RESULT::Success!!
