我正在尝试通过 FOSRestBundle 和 JMS Serializer 返回一个带有指向 Sonata\MediaBundle\Entity 的 ManyToOne 链接的 JSON 对象（'Module'）。我该怎么做呢？
这是我做的一个黑客，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！
