Question

我正在开发一个实现公共Feed的项目。我有一个Comment实体，允许用户向每个Feed提交评论。但是，我希望用户也能够提交对评论的回复。

为此，我在$response实体中拥有Comment属性。我假设保存响应与保存注释相同，因为响应也是注释。

但是，我不确定如何在没有id的情况下访问评论并保存该评论的回复。

在我的FeedController我保存了这样的评论;

 $commentForm = $this->createForm(CommentType::class);
    $commentForm->handleRequest($request);
    if ($commentForm->isSubmitted() && $commentForm->isValid()) {
        $content = $commentForm->get('content')->getData();
        $feed_id = $feed;

        $comment= EntityBuilder::newComment($content, $user, $feed_id);

        $commentService->saveEntity($comment);

        if(!is_null($comment)){
            $this->addFlash(
                'commentsuccess',
                'Your reply was successfully posted!'
            );
        }

        return $this->redirect($this->generateUrl('showFeed', array('slug' => $feed->getSlug()), UrlGeneratorInterface::ABSOLUTE_URL));

    }

这是评论实体;

* @ORM\Entity(repositoryClass="AppBundle\Repository\CommentRepository")
* @ORM\Table(name="comment")

    return $this;
}

public function setCreatedby(\AppBundle\Entity\User $createdby = null)

    return $this;
}

{
    return $this->createdby;
}

public function setCreatedAt($createdAt)
{
    $this->createdAt = $createdAt;

    return $this;
}

/**

 *

public function getCreatedAt()
{
    return $this->createdAt;
}

/**

 *
 * @param \DateTime $updatedAt
 *
 * @return Comment
 */
public function setUpdatedAt($updatedAt)
{
    $this->updatedAt = $updatedAt;

    return $this;
}

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


/**
 * Set response
 *
 * @param \AppBundle\Entity\Comment $response
 *
 * @return Comment
 */
public function setResponse(\AppBundle\Entity\Comment $response = null)
{
    $this->response = $response;

    return $this;
}

/**
 * Get response
 *
 * @return \AppBundle\Entity\Comment
 */
public function getResponse()
{
    return $this->response;
}

}

即使我为响应创建了另一种表单类型，我仍然不确定如何保存特定注释的响应。

我的推荐是实施父/子方法，向ManyToOne实体添加（$parent）Comment字段及其反转（OneToMany）$children属性。稍后，您可以在CollectionType属性的CommentType中添加$children表单字段，因此每条评论可能需要多个响应。

不要担心父id，CollectionType会为你工作。详细了解CollectionType的工作原理glyph EURO SIGN, code point U+20AC。
