Doctrine Timestampable扩展不会持久化

Question

我为我的symfony学说设置了Doctrine timestampable,其他实体正在处理这个问题,但其中一个并没有设置任何日期.

    use Doctrine\ORM\Mapping as ORM;
    use Gedmo\Mapping\Annotation as Gedmo;
    use Digital\UserBundle\Entity\User;

    /**
     * ChallengeScore
     *
     * @ORM\Table(name="app_challenges_scores")
     * @ORM\InheritanceType("JOINED")
     * @ORM\DiscriminatorColumn(name="type", type="string")
     * @ORM\DiscriminatorMap({"race" = "Digital\ApplicationBundle\Entity\Race\ChallengeScore", "individual" = "ChallengeScore"})
     * @ORM\Entity(repositoryClass="Digital\ApplicationBundle\EntityRepository\ChallengeScoreRepository")
     */
    class ChallengeScore


    /**
     * @var \DateTime
     *
     * @ORM\Column(name="date_added", type="datetime")
     * @Gedmo\Timestampable(on="create")
     */
    private $date_added;

    /**
     * @var \DateTime
     *
     * @ORM\Column(name="date_modified", type="datetime")
     * @Gedmo\Timestampable(on="update")
     */
    private $date_modified;


    /**
     * Set date_added
     *
     * @param \DateTime $dateAdded
     *
     * @return self
     */
    public function setDateAdded($dateAdded)
    {
        $this->date_added = $dateAdded;

        return $this;
    }


    /**
     * Get date_added
     *
     * @return \DateTime
     */
    public function getDateAdded()
    {
        return $this->date_added;
    }


    /**
     * Set date_modified
     *
     * @param \DateTime $dateModified
     *
     * @return self
     */
    public function setDateModified($dateModified)
    {
        $this->date_modified = $dateModified;

        return $this;
    }


    /**
     * Get date_modified
     *
     * @return \DateTime
     */
    public function getDateModified()
    {
        return $this->date_modified;
    }
}

我想也许这个配置存在一个问题,定义了继承...有人能发现问题吗？

没有错误只有00000持续到db(所以没有)

Answer 1

不要忘记将以下内容添加到app/config/services.yml:

services:
    gedmo.listener.timestampable:
        class: Gedmo\Timestampable\TimestampableListener
        tags:
            - { name: doctrine.event_subscriber, connection: default }
        calls:
            - [ setAnnotationReader, [ '@annotation_reader' ] ]

这基本上做的是它"监听"如果触发事件来更新/创建数据库中的实体并且它将设置日期.

我希望这解决了这个问题.

在DoctrineExtensions示例中

可以看到没有setters成员timestampable，所以只删除setDateAdded()和setDateModified()方法
