，当我的实体包含某些条件时，我想为序列化程序添加其他组，我为Notification创建事件serializer.pre_serialize，并在检查条件后在序列化上下文中添加其他组，但作为回应，它不起作用。示例我想要添加一些嵌套到我的Notification它将是另一个实体，例如Notification并且这个实体有一些组，并且在我创建上下文Question之后设置它一切正常，但是当我尝试在SerializationContext::create()中添加其他组时，它不起作用
这是我的实体
serializer.pre_serialize和我在事件中添加的另一个实体
class Notifications
{
use TraitTimestampable;
const GROUP_POST_NOTIFICATION = 'post_notifications';
const GROUP_GET_NOTIFICATIONS = 'get_notifications';
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
* @Annotation\Groups({
* "get_notifications"
* })
*/
private $id;
/**
* @var object
*
* @Annotation\Groups({
* "get_notifications"
* })
*/
private $providerEntity;
但作为回应我有
class Questions implements NotificationInterface
{
use TraitTimestampable;
const GROUP_POST = 'post_question';
const GROUP_GET = 'get_question';
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
* @Annotation\Groups({
* "get_question"
* })
*/
private $id;
/**
* @return array
*/
public static function getGetGroup()
{
return [self::GROUP_GET];
}
但作为回应我有
public function onPreSerializeNotifications(PreSerializeEvent $event)
{
/** @var Notifications $notifications*/
$notifications = $event->getObject();
$provider = $notifications->getProvider(); //this is Questions::class
$this->providerEntity = $this->entityManager->getRepository($provider)
->findOneBy(['id' => $notifications->getProviderId()]);
$notifications->setProviderEntity($this->providerEntity);
$attr = $event->getContext()->attributes;
$groups = array_merge($attr->all()['groups'], $provider::getGetGroup());
$attr->set('groups', $groups);
}
