【问题描述】：
如果有人可以帮助我，我将不胜感激。我花了几个小时来解决这个问题，但找不到解决方案。
只要我不需要 PersonType 类中的第二个 AddressType 类，代码就可以正常工作（见下文）。这样的事情不起作用：
// PersonType:
$builder
->add('firstname', 'text')
->add('middlename', 'text')
->add('lastname', 'text')
->add('address', new AddressType())
->add('address', new AddressType());
相同类型的多个 FormType 将具有相同的 HTML-ID，因此 Symfony 不会呈现第二个地址。我有几个关于该主题的问题：
我是否需要 CollectionType，即使我只需要两个地址还是有其他方法（我不需要用户能够动态添加另一个地址）？
-
假设我需要 CollectionType。一开始 CollectionType 是空的。但我从一开始就需要两个地址。我在 Symfony-Documentation 中发现以下内容从一开始就创建了一些集合项：Form Collections
// Controller: $task = new Task(); // dummy code - this is here just so that the Task has some tags // otherwise, this isn't an interesting example $tag1 = new Tag(); $tag1->setName('tag1'); $task->getTags()->add($tag1); $tag2 = new Tag(); $tag2->setName('tag2'); $task->getTags()->add($tag2);
现在，请看看我的控制器。我什至不创建实体。我只创建嵌入了所有其他表单类型的主表单类型。我如何或在哪里可以创建这两个地址？甚至我的整个控制器代码都错了？
有没有办法告诉 symfony 第一个地址和第二个地址不一样？如何设置每个 AddressType 的名称/ID？ （这个solution 已经失效了。）
在我的控制器中生成表单真的可以吗？我不会将实体或数组传递给表单。它有效，但我想知道为什么....否则我不知道如何将我需要的所有实体传递给表单（合同、人员、地址、客户、付款等）。
提前致谢！
控制器：
class DefaultController extends Controller{
/**
* @return array
* @Route("/private")
* @Template("DmmGenericFormBundle:Default:index.html.twig")
*/
public function indexAction(Request $request)
{
// This formtype class has all other form type classes
$privateRentDepositForm = new PrivateRentDepositType();
$form = $this->createForm($privateRentDepositForm);
$form->handleRequest($request);
if($form->isValid()){
$contract = $form->get('contract')->getData();
$privateContractDetails = $form->get('privateContractDetails')->getData();
$customer = $form->get('customer')->getData();
$customerPerson = $form->get('customer')->get('person')->getData();
$privateRealEstate = $form->get('privateRealEstate')->getData();
$privateRealEstateAddress = $form->get('privateRealEstate')->get('address')->getData();
$landlord = $form->get('privateRealEstate')->get('landlord')->getData();
$landlordPerson = $form->get('privateRealEstate')->get('landlord')->get('person')->getData();
$caretakerPerson = $form->get('privateRealEstate')->get('landlord')->get('caretaker')->get('person')->getData();
$payment = $form->get('payment')->getData();
$contract->addPerson($customerPerson);
$contract->addPerson($landlordPerson);
$contract->addPerson($caretakerPerson);
$contract->setPrivateContractDetails($privateContractDetails);
$customer->setPayment($payment);
$landlord->setPrivateRealEstate($privateRealEstate);
$privateRealEstate->addCustomer($customer);
$privateRealEstate->setLandlord($landlord);
$em = $this->get('doctrine')->getManager();
$em->persist($contract);
$em->flush();
}
return array('form' => $form->createView());
}
表单类型类：
class PrivateRentDepositType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder

->add('payment', new PaymentType())
->add('save', 'submit');

人物类型类：

*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('firstname', 'text')

);
}
/**

public function getName()
{
return 'dmm_bundle_genericformbundle_person';
}
}
地址类型类：
class AddressType extends AbstractType
{
/**

*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('street', 'text')

->add('zip', 'text')
->add('city', 'text')
->add('extra', 'text')
->add('country', 'text')
->add('postOfficeBox', 'integer')
;
}
/**

*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(
[
'data_class' => 'Dmm\Bundle\GenericFormBundle\Entity\Address',
'config' => null,

);
}
/**

public function getName()
{
return 'dmm_bundle_genericformbundle_address';

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

->add('person', new PersonType())
->add('birthplace', 'text')
->add('email', 'email')
->add('phone', 'text');
}
/**
* @param OptionsResolverInterface $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(
[
'data_class' => 'Dmm\Bundle\GenericFormBundle\Entity\Customer',
'config' => null,
]
);
}
/**

public function getName()
{
return 'dmm_bundle_genericformbundle_customer';
}
}
数据库关联
Contract:Person = 1:n (Owning Side: Person, ArrayCollection for Person in Contract)
Person:Address = 1:n (Owning Side: Address, ArrayCollection for Address in Person)
Person:Customer = 1:1（拥有方：客户，客户是一个人）
编辑： Cerad 对解决方案 2 的代码编辑 控制器 - 创建所有对象
$contract = new Contract();
$contractDetails = new PrivateContractDetails();
$contract->setPrivateContractDetails($contractDetails);
$customer1Person = new Person();
$customer1Address1 = new Address();
$customer1Address1->setAddressType('someAddress');
$customer1Address2 = new Address();
$customer1Address2->setAddressType('someAddress');
$customer1Person->addAddress($customer1Address1);
$customer1Person->addAddress($customer1Address2);
$contract->addPerson($customer1Person);
$customer1 = new Customer();
$customer1->setPerson($customer1Person);
$customer2Person = new Person();
$customer2Address1 = new Address();
$customer2Address1->setAddressType('someAddress');
$customer2Address2 = new Address();
$customer2Address2->setAddressType('someAddress');
$customer2Person->addAddress($customer2Address1);
$customer2Person->addAddress($customer2Address2);
$contract->addPerson($customer2Person);
$customer2 = new Customer();
$customer2->setPerson($customer2Person);
$landlordPerson = new Person();
$landlordPersonAddress = new Address();
$landlordPersonAddress->setAddressType('someAddress');
$landlordPerson->addAddress($landlordPersonAddress);
$contract->addPerson($landlordPerson);
$landlord = new Landlord();
$landlord->setPerson($landlordPerson);
$prEstate = new PrivateRealEstate();
$prEstateAddress = new Address();
$prEstateAddress->setAddressType('someAddress');
$prEstate->setAddress($prEstateAddress);
$landlord->setPrivateRealEstate($prEstate);
$prEstate->addCustomer($customer1);
$prEstate->addCustomer($customer2);
$caretakerPerson = new Person();
$caretakerAddress = new Address();
$caretakerAddress->setAddressType('someAddress');
$caretakerPerson->addAddress($caretakerAddress);
$contract->addPerson($caretakerPerson);
$caretaker = new Caretaker();
$caretaker->addLandlord($landlord);
$caretaker->setPerson($caretakerPerson);
$payment = new Payment();
$customer1->setPayment($payment);
$privateRentDepositForm = new PrivateRentDepositType();
$form = $this->createForm($privateRentDepositForm, $contract);
我换了
->add('address', new AddressType());
与
->add('address', 'collection', array(
'type' => new AddressType()
))
现在我得到以下异常： 表单的视图数据应为标量、数组或 \ArrayAccess 的实例类型，但它是 Dmm\Bundle\GenericFormBundle\Entity\Contract 类的实例。您可以通过将“data_class”选项设置为“Dmm\Bundle\GenericFormBundle\Entity\Contract”或添加一个视图转换器来将 Dmm\Bundle\GenericFormBundle\Entity\Contract 类的实例转换为标量、数组或\ArrayAccess 的一个实例。
在 ContractType 中，data_class 设置为正确的类。只有在 PrivateRentDepositType 中，data_class 才设置为 null。但是 PrivateRentDepositType 是不同类型的集合。我试图将 data_class 设置为 'Dmm\Bundle\GenericFormBundle\Entity\Contract' 但这会导致另一个异常：属性“contract”和方法之一“getContract()”、“contract()”、“isContract ()"、"hasContract()"、"__get()" 存在并且在类 "Dmm\Bundle\GenericFormBundle\Entity\Contract" 中具有公共访问权限。
