Question

我的实体中有一个字段：

/**
  * slug field
  *
  * @Gedmo\Slug(fields={"name"})
  * @ORM\Column(type="string", length=255, unique=true)
  *
  * @var string
  */
 private $slug;

现在，我想修改此字段以从两个字段中创建子弹。

/**
  * slug field
  *
  * @Gedmo\Slug(fields={"id", "name"})
  * @ORM\Column(type="string", length=255, unique=true)
  *
  * @var string
  */
  private $slug;

但是，当我保存此更改时，它仍然只能从“名称”字段中生成。如何保存此注释更改？

您是否尝试过将它用于新实体？更改配置后，旧的子弹不会自动更新。您必须取消设置所有现有实体的段，然后再次保存它们以生成新段。我用命令来做到这一点：

<?php
namespace AppBundle\Command;

use AppBundle\Entity\YourEntityClass;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;

/**
 * Generates slugs again
 */
class UpdateSlugsCommand extends ContainerAwareCommand
{
    protected function configure()
    {
        $this
            ->setName('appbundle:update-slugs')
            ->setDescription('generate new slugs')
            ->setHelp('needed after changing the config');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $em = $this->getContainer()->get('doctrine')->getEntityManager();

        $entities = $em->getRepository(YourEntityClass::class)->findAll();
        foreach ($entities as $entity) {
            // unset slug to generate a new one
            $entity->setSlug(null);
            $em->persist($entity);
        }
        $em->flush();
    }
}
