FOSElasticaBundle更新嵌套实体

Question

为什么我有空的嵌套实体？我有索引天赋。在数据库人才有嵌套用户的情况下，当我现在更新或创建人才时，它不会在ElasticSearch中作为嵌套对象被更新，我不明白为什么？

fos_elastica:
clients:
    default:
      host: %elastica_host%
      port: %elastica_port%
      headers: { Authorization: Basic %elastica_auth_header% }

indexes:
    profile:
        finder: ~
        types:
             talent:
                mappings:
                    id:
                       type: integer
                    slug:
                       type: string
                    description:
                       type: string
                    user:
                        type: "nested"
                        properties:
                             id: ~
                             username:
                                type: string

我搜索并找到有关侦听器重写postPersist、postUpdate和preRemove的信息。

fos_elastica.listener.talent:
    class: Artel\SiteBundle\EventListener\ElasticaCourseListener
    arguments:
        - @fos_elastica.object_persister.user.user
        - ['postPersist', 'postUpdate', 'preRemove']
        - @fos_elastica.indexable
    calls:
        - [ setContainer, ['@service_container', @fos_elastica.object_persister.profile.talent ] ]
    tags:
        - { name: 'doctrine.event_subscriber' }

然后，我自己的侦听器Artel\SiteBundle\EventListener\ElasticaCourseListener如下所示：

<?php

    namespace Artel\SiteBundle\EventListener;

    use Doctrine\Common\EventArgs;
    use FOS\ElasticaBundle\Doctrine\Listener as BaseListener;
    use FOS\ElasticaBundle\Persister\ObjectPersister;
    use Symfony\Component\DependencyInjection\ContainerInterface;
    use Artel\ProfileBundle\Entity\Developer;

    class ElasticaCourseListener extends BaseListener
    {
        private $container;
        private $objectPersisterSession;

        public function setContainer(ContainerInterface $container, ObjectPersister $objectPersisterSession)
        {
            $this->container = $container;
            $this->objectPersisterSession = $objectPersisterSession;
        }

        public function postUpdate(EventArgs $args)
        {
            $entity = $args->getEntity();

            if ($entity instanceof Developer) {
                $this->scheduledForUpdate[] = $entity;
                foreach ($entity->getUser() as $session) {
                    $this->objectPersisterSession->replaceOne($session);
                }
            }
        }
    }

现在，我有错误

Symfony\Component\Debug\Exception\ContextErrorException 运行时注意: Artel\SiteBundle\EventListener\ElasticaCourseListener::postUpdate()声明应该与FOS\ElasticaBundle\Doctrine\Listener::postUpdate(Doctrine\Common\Persistence\Event\LifecycleEventArgs $eventArgs兼容)

请帮帮忙

Answer 1

你必须用这个：

use Doctrine\Common\Persistence\Event\LifecycleEventArgs;

忘了那个吧：

use Doctrine\Common\EventArgs;

(该原则中有一些更新;)
