Question

我正在尝试通过FOSRestBundle和JMS Serializer将带有ManyToOne链接的JSON对象（'Module'）返回到Sonata \ MediaBundle \ Entity。我应该怎么做呢？

这是我做过的黑客攻击，但不认为这是最好的做法。

class Module
{
    ...
    /**
     * @var Application\Sonata\MediaBundle\Entity\Media
     *
     * @ORM\ManyToOne(targetEntity="Application\Sonata\MediaBundle\Entity\Media",  inversedBy="module")
     * @ORM\JoinColumn(name="hero_image_id", referencedColumnName="id")
     * @JMS\Expose()
     */
    private $heroImage;
    ...
}

class Media extends BaseMedia
{
   ...
   /**
     * A Quick hack not the best method.
     *
     * @JMS\VirtualProperty
     * @JMS\SerializedName("url")
     *
     * @return string
     */
    public function getUrlMethod()
    {
        global $kernel;

        $imageProvider = $kernel->getContainer()->get('sonata.media.provider.image');

        return $imageProvider->generatePublicUrl($this, 'reference');
    }
    ...
}

谢谢你！

        $event->getVisitor()->addData('url',$imageProvider->generatePublicUrl($event->getObject(), 'reference'));
    }
}

您可能希望看到Add extra fields using JMS Serializer bundle，因为它有一个示例，关于如何向依赖于外部类的序列化数据添加其他字段。

FOSRestbundle，JMS Serializer和SonataMediaBundle返回图像的公共URL
