Php 为多对多嵌入的表单&；symfony2中的多对一。

当我尝试在Symfony2中为多对多关系或多对一关系嵌入表单时，我遇到了一个问题

我有两个实体，分别称为'Address'和'AddressType'，它们是相关的，如下面代码所示。 我试图做的是，当我为Address创建表单时，我嵌入了AddressType表单。我已经尝试将AddressType集合嵌入到Address表单中，但是当我尝试将结果嵌入到Address时，它似乎不起作用

地址实体

namespace Webmuch\ProductBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**
 * @ORM\Entity
 */
class Address
{
    protected $id;
    protected $line1;
    protected $line2;
    protected $state;
    protected $city;
    protected $zip;
    protected $country;
    protected $phone;

    /**
     * @ORM\ManyToOne(targetEntity="AddressType")
     * @ORM\JoinColumn(name="address_type_id", referencedColumnName="id")
     */
    protected $type;

    public function __construct()
    {
        $this->type = new ArrayCollection();
    }

    /**
     * Set type
     *
     * @param Webmuch\ProductBundle\Entity\AddressType $type
     */
    public function setType(\Webmuch\ProductBundle\Entity\AddressType $type)
    {
        $this->type = $type;
    }

    /**
     * Get type
     *
     * @return Webmuch\ProductBundle\Entity\AddressType 
     */
    public function getType()
    {
        return $this->type;
    }
}

AddressType实体：

namespace Webmuch\ProductBundle\Entity;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class AddressType
{

    protected $id;

    protected $title;

    public function __construct()
    {
        $this->title = false;
    }


}

格式部分->

表格

地址类型：

namespace Webmuch\AdminBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;

class AddressType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder
            ->add('line1')
            ->add('line2')
            ->add('city')
            ->add('zip')
            ->add('country')
            ->add('phone')
        ->add('type','collection', array( 'type' =>  new AddressTypeType(),
                                              'allow_add' => true,
                                              'prototype' => true,
                                              'by_reference' => false,
                                              ));
    }
    public function getDefaultOptions(array $options)
    {
        return array('data_class' => 'Webmuch\ProductBundle\Entity\Address');
    }

    public function getName()
    {
        return 'address';
    }

}

地址类型：

namespace Webmuch\AdminBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;

class AddressTypeType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder->add('title');
        ;
    }

    public function getDefaultOptions(array $options)
    {
        return array(
            'data_class' => 'Webmuch\ProductBundle\Entity\AddressType',
        );
    }

    public function getName()
    {
        return 'addresstypetype';
    }

}

控制器部分->

namespace Webmuch\AdminBundle\Controller;
    use Symfony\Bundle\FrameworkBundle\Controller\Controller;
    use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
    use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
    use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
    use Webmuch\ProductBundle\Entity\Address;
    use Webmuch\AdminBundle\Form\AddressType;

    /**
     * Address controller.
     *
     * @Route("/cusadmin/address")
     */
    class AddressController extends Controller
    {
         /**
     * Displays a form to create a new Address entity.
     *
     * @Route("/new", name="admin_address_new")
     * @Template()
     */
        public function newAction()
        {
            $entity = new Address();

            $form   = $this->createForm(new AddressType(), $entity);

            return array(
                'entity' => $entity,
                'form'   => $form->createView()
            );
        }

    }

我花了一整天的时间在这上面，我尝试了很多东西，但都没能成功

感谢您的帮助

谢谢

编辑表单地址类型：并编写此代码，可能这是完整的帮助

 public function buildForm(FormBuilder $builder, array $options)
    {
        $builder
            ->add('line1')
            ->add('line2')
            ->add('city')
            ->add('zip')
            ->add('country')
            ->add('phone')
            ->add('type','entity', array('class'=>'WebmuchProductBundle:AddressType','property'=>'value','multiple'=>true  
             ));
