我想获得一系列嵌入式文档.我将数据放入数据库中,如下所示:

$dm->getRepository('BundleUserBundle:User')->addRatedPostById($user->getId(), new RatedPost($id, $type));

......工作正常.现在我在mongo控制台中看到了新数据,但是当我试图通过该getRatedPosts()方法获取此数据时,它返回null而不是ArrayCollection.怎么了？

    {
        $this->ratedPosts[] = $ratedPosts;
    }

   /**
    * Remove ratedPosts
    *
    * @param Bundle\UserBundle\Document\RatedPost $ratedPosts
    */
    public function removeRatedPost(\Bundle\UserBundle\Document\RatedPost $ratedPosts)
    {
        $this->ratedPosts->removeElement($ratedPosts);
    }

   /**
   * Get ratedPosts
   *
   * @return Doctrine\Common\Collections\Collection $ratedPosts
   */
   public function getRatedPosts()
   {
       return $this->ratedPosts;
   }

/**
 * @MongoDB\EmbeddedDocument
 */
