我有2个相关实体，Invoice＆amp; InvoiceRow，我有一个表格让人们创建新发票。
我还加载了一些测试数据，我加载它们以使用测试数据为数据库播种，无论我如何将实体持久化到数据库，InvoiceRow中的invoice_id总是null
在灯具中我试过坚持发票
InvoiceRow.php：
namespace Settleup\InvoiceBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**

/**

/**

protected $description;
/**

我有一个用于填充两个表中的行的表单：
class InvoiceType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('reference')
->add('rows', 'collection', array(
'type' => 'invoice_row',
'allow_add' => true,
'by_reference' => false
))
->add('invoiceAddress', 'sylius_address');
$builder->addEventListener(
FormEvents::PRE_SET_DATA,
function(FormEvent $event) {
$form = $event->getForm();
$form->add('merchant', 'hidden');
}
);
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Settleup\InvoiceBundle\Entity\Invoice',
'cascade_validation' => true
));
}
public function getName()
{
return 'settleup_invoicebundle_invoicetype';
}
}
使用控制器上的操作保存该表单时：
public function createAction(Request $request)
{
$entity = new Invoice();
$form = $this->createForm(new InvoiceType(), $entity);
$form->bind($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$entity->setMerchant($this->getUser());
$em->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('invoice_show', array('id' => $entity->getId())));
} else {
}
return array(
'entity' => $entity,
'form' => $form->createView(),
);
}
除了InvoiceRow缺少invoice_id之外，两行都包含所有正确的数据。
答案 0 :(得分：0)
有点晚了但可能对其他人有用
1）尝试持有拥有方（具有FK的那一方），即invoiceRow
2）我遇到了持久存在相关实体的问题，因为id字段没有遵循默认值。添加它使它工作：
* @ORM\ManyToOne(targetEntity="Personas", fetch="EAGER", inversedBy="cuentasCorriente",
* cascade={"persist", "refresh"})
* @ORM\JoinColumn(name="persona_id", referencedColumnName="ID", nullable=false)
referencedColumnName =“ID”参见“ID”！=“id” 当我将Doctrine添加到遗留系统时，别无选择。
