我有3个实体，一个作为参考连接表（多对多）和其他字段。我想要实现的是从Placement表单中嵌入（PlacementTypeReference）表单。集合表单的数量必须与placementType数据库表中的行数完全相同。 这是实体：

和 PlacementTypeReference 这将是一个连接表

/**

*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**

* @return PlacementTypeReference
*/
public function setPlacement(Placement $placement = null)
{
if($this->placement !== null)
{
$this->placement->removePlacement($this);
}
if($placement !== null)
{
$placement->addPlacement($this);
}
$this->placement = $placement;
return $this;
}
/**
* Get placement
*
* @return Placement
*/
public function getPlacement()
{
return $this->placement;
}
/**

*
* @param PlacementType $placementTypeId
* @return PlacementTypeReference
*/
public function setPlacementType(PlacementType $placementType = null)
{
if($this->placementType !== null)
{
$this->placementType->removePlacementType($this);
}
if($placementType !== null)
{
$placementType->addPlacementType($this);
}
$this->placementType = $placementType;
return $this;
}
/**
* Get placementType
*
* @return PlacementType
*/
public function getPlacementType()
{
return $this->placementType;
}
/**

*/

}
}
我正在尝试构建一个表单，我可以在其中嵌入PlacementTypeReferenceType表单的集合，表单数量由PlacementType表中的行数和预先填充的placementType id确定。
以下是展示位置的类型： 的 PlacementType
<?php
namespace AppBundle\Form\Type;
use Doctrine\ORM\EntityManager;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Doctrine\ORM\EntityRepository;
use AppBundle\Form\Type\PlacementTypeReferenceType;
class PlacementType extends AbstractType
{
private $em;
public function __construct($em)
{
$this->em = $em;
}
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
->add('crm_id',null, array(
'required' => false,
))
->add('defaultPrice', null, array(
'required' => false,
))
->add('placements', new PlacementTypeReferenceType($this->em)
)
->add('site',null, array(
'required' => true,
))
->add('payment_type','choice',array(
'attr' => array(
'class' => 'payment_type'
),
'choices' => array(
'impression' => 'impression',
'monthly' => 'monthly',
'daily' => 'daily',
'percentage' => 'percentage',
'rotation' => 'rotation',
),
'data' => 'impression'
))
->add('default_rotations', 'choice',array(
'required' => false,
'choices' => array(
1 => 1,
2 => 2,
3 => 3,
4 => 4,
5 => 5,
),
'data' => 0,
'placeholder' => 'Choose rotations',
'mapped' => false
))
->add('isActive',null, array(
'label' => 'Active',
'required' => false,
'attr' => array(
'class' => 'js-switch',
'data-switchery' => true,
'style' => 'display:none'
)))
;
}
/**
* @param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Placement',
'cascade_validation' => true,
));
}
/**
* @return string
*/
public function getName()
{
return 'appbundle_placement';
}
}
这里是 PlacementTypeReferenceType
<?php
namespace AppBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\FormBuilderInterface;
use Doctrine\ORM\Query;
class PlacementTypeReferenceType extends AbstractType
{
private $em;
public function __construct($em)
{
$this->em = $em;
}
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
/* Find all placement types and build form from them */
$placementTypes = $this->em->getRepository('AppBundle:PlacementType')->findAll(Query::HYDRATE_ARRAY);
// THIS DOESN'T WORK ALSO !!!
/*if(!empty($placementTypes))
{
foreach($placementTypes as $item) {
$builder
->add('placementType','checkbox',array(
'value' => $item->getId(),
'label' => $item->getName(),
))
->add('coefficient');
}
}*/
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\PlacementTypeReference',
)
);
}
public function getName()
{
return 'appbundle_ptreference';
}
}
我还尝试制作集合数据原型，并将placementTypes从控制器发送到twig，用javascript循环它并为每一行制作原型实例但我希望有一种更清洁的方式。 任何人都可以建议如何解决这个或在哪里看？
