我有一个包含 4 个 realtionships 的表格，但其中 2 个有问题。这是我的表单的代码：
<?php
namespace Psw\AdminBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class MeatType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name_pl')
->add('name_en')
->add('jm')
->add('vat')
->add('net_price')
->add('min')
->add('new')
->add('promotion', 'entity', array(
'class' => 'PswAdminBundle:Promotions',
'empty_value' => 'No promotion',
'required' => false
))
->add('promotion_price')
->add('producer', 'entity', array(
'class' => 'PswAdminBundle:MeatProducers'
))
->add('animals')
->add('categories')
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Psw\AdminBundle\Entity\Meat'
));
}
public function getName()
{
return 'psw_adminbundle_meattype';
}
}

关于动物和类别的多对多理论没有问题。但是我拥有多对一的促销和制作人会导致一些问题。
问题是当尝试插入/更新记录时，学说调用 __toString 方法而不是 getId 来获取要放入数据库的值。
我与其他实体有这样的工作示例，它们几乎相同，但在这种情况下它只是不想工作。
控制器代码来自 crud 生成器，如有必要，我没有更改任何内容，我可以发布它。
问题是如何让它使用 getId 方法？
