我有一个包含4个版本的表单但有2个问题。 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';
    }
}

动物和类别的许多对许多事件都没有问题。 但促销和生产者，我有很多对一个问题。

问题是当尝试插入/更新记录时，调用__toString方法而不是getId来获取要放入数据库的值。

我和其他实体一样有这样的例子，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，如果有必要，我没有更改任何内容我可以发布它。

问题是如何使用getId方法？

答案 0 :(得分：3)

这里的问题不在于__toString，它位于您的映射注释中。您不应该使用@Column进行关联映射。相反，使用@JoinColumn：

/**
 * @ORM\ManyToOne(targetEntity="Promotions")
 * @ORM\JoinColumn(name="promotion_id", referencedColumnName="id")
 */
private $promotion;
