我有一个私有(private)消息包/实体，允许我的用户在他们之间发送消息。

其字段如下:

/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**
 * @var string
 * @Assert\NotBlank(message="private_message.title.blank")
 * @ORM\Column(name="title", type="string", length=50)
 */
protected $title;

/**
 * @Assert\NotBlank(message="private_message.receiver.blank")
 * @AcmeAssert\IsHimself(message="private_message.receiver.himself", groups={"new"})
 * @ORM\ManyToOne(targetEntity="MedAppBundle\Entity\User")
 * @ORM\JoinColumn(referencedColumnName="id")
 */
protected $receiver;
/**
 * @ORM\ManyToOne(targetEntity="MedAppBundle\Entity\User")
 * @ORM\JoinColumn(referencedColumnName="id")
 */
protected $sender;

/**
 * @var string
 * @Assert\NotBlank(message="private_message.content.blank")
 * @ORM\Column(name="content", type="string")
 */
protected $content;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="sentAt", type="datetime")
 */
protected $sentAt;


/**
 * @var boolean
 *
 * @ORM\Column(name="isSpam", type="boolean")
 */
protected $isSpam = false;


/**
 * @var \DateTime
 *
 * @ORM\Column(name="seenAt", type="datetime",nullable=true)
 */
protected $seenAt = null;

/**
 * @ORM\ManyToOne(targetEntity="PrivateMessageBundle\Entity\Message",inversedBy="replies")
 * @ORM\JoinColumn(referencedColumnName="id",nullable=true)
 */
protected $replyof;

/**
 * @ORM\OneToMany(targetEntity="PrivateMessageBundle\Entity\Message", mappedBy="replyof")
 **/
private $replies;

public function __construct() {
    $this->replies = new ArrayCollection();
}

注意 replyof 字段，它引用了另一个 message，而 replies 引用了一个 messages。如果 replyof 为 null，则该消息不是对任何消息的回复。

我有一个带有宏的 Twig 模板，可以显示用户的消息和该消息的所有回复。我想做的是在每条消息下方都有一个回复文本字段，就像 Gmail 一样，它允许我为每条消息添加回复。

但是当我将它添加到模板时，只有一个被渲染，因为它只有一个 Id。如何在每次回复后添加回复表单？他们的 FormType 应该是什么样子？

这也是我的 Twig 模板:

  {% macro displayReply(reply,replyform) %}
        {% import _self as macros %}


        {# <li> id: {{ reply.id }} </li>
        <li> sent by: {{ reply.sender }} </li>
        <li> title: {{ reply.title }} </li>
        <li> content: {{ reply.content }} </li>
        <li> date: {{ reply.sentAt|date('d-m-Y H:i:s') }} </li>
        <a  href="{{ path('private_message_new',{'msg':reply.id}) }}">  reply  </a>
        <hr> #}
        <div class="panel panel-default">
            <div class="panel-body">
                <div class="message-info">
                    <input type="hidden" name="messageid" id="messageId" value="{{ reply.id }}">

                    <div class="message-title clearfix">
                        <h4 class="pull-left">{{ reply.title }}</h4>
                    </div>
                    <hr class="lite-line">
                    <div class="message-sender clearfix">
                        <div class="pull-left sender">
                            {{ reply.sender }}
                        </div>
                        <div class="pull-right">

                            <a class="btn btn-start-order" role="button"

    {% import _self as macros %}
    {# use the macro #}

                        </div>
                    </div>

    {% for reply in message.replies %}

        {% if loop.first %}<div class="replies">{% endif %}
        {{ macros.displayReply(reply ,replyform) }}
        {% if loop.last %}</div>{% endif %}
    {% endfor %}

请注意，我首先显示消息，然后对其应用宏，将其所有回复显示为树。它也将以递归方式显示回复的回复，一直到叶节点。我在每个之后添加了一个“回复表单”，但我不确定 FormType 应该如何。

我的回复表单类型是这样的，但我很确定它是错误的。

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('title')
        ->add('content', 'textarea')
      ;

}

至于回复的其他字段，我在 Controller 中处理它们。不过，我认为我应该在收到来自表单的消息后执行此操作。像这样，从表单数据中获取标题、内容和回复。

   $messages = $this->getDoctrine()->getRepository('PrivateMessageBundle:Message');
    $isforme = $messages->findOneBy(array('receiver' => $this->getUser(), 'id' => $msg));
    $message = new Message();
    $message->setSender($this->getUser());
    $message->setSentAt(new \Datetime('now'));
    $message->setReplyof($isforme);
    $message->setReceiver($isforme->getSender());
    $form = $this->createForm(new MessageReplyType($em), $message);

编辑

好的，所以我通过添加隐藏字段和硬编码多个表单而不是使用 FormTypes 做了一些可行的事情，但我仍然认为这可以通过更好、更可重用的方式来完成。

                    <form name="privatemessagebundle_message" method="post" action="" id="{{ reply.id }}">
                        <div><label for="privatemessagebundle_message_title" class="required">Title</label><input
                                    type="text" id="privatemessagebundle_message_title"
                                    name="privatemessagebundle_message[title]" required="required" maxlength="50"></div>
                        <div><label for="privatemessagebundle_message_content" class="required">Content</label><textarea
                                    id="privatemessagebundle_message_content"
                                    name="privatemessagebundle_message[content]" required="required"></textarea></div>
                        <input type="hidden" id="privatemessagebundle_message_replyof"
                               name="privatemessagebundle_message[replyof]" value="{{ reply.id }}">
                        <input type="submit">
                        <input type="hidden" id="privatemessagebundle_message__token"
                               name="privatemessagebundle_message[_token]"
                               value="{{ csrf_token('privatemessagebundle_message') }}">
                    </form>

有人有更好的想法吗？

最佳答案

我做到了!我使用了这个 question 的答案.

由于我使用的是 foreach 循环并且它们的性能可能有点低，欢迎任何有更好想法的人。仍然有赏金可以领取。

我正在通过 createNamedBuilder 为我的每个表单创建一个表单。它们将具有不同的名称，因此不同的 id 和 Symfony 将渲染它们。然后，我可以将它们呈现在我想要的位置，并通过从数据库中获取的唯一 ID 很好地处理它们的请求。

 $genforms = $this->genReplyForms($isforme); // run the function for my message
            $forms_views = $genforms['views']; // pass to the view
            $forms= $genforms['forms']; // handle request... 

这是生成表单的函数。它为我的消息的每个回复递归生成它们。

    public function genReplyForms(Message $message)
{

    $id = $message->getId();

    $msgreply[$id] = new Message();

    $forms[$id] = $this->container
        ->get('form.factory')
        ->createNamedBuilder('form_'.$id, new MessageReplyType(), $msgreply[$id])
        ->getForm();

    $forms_views[$id] = $forms[$id]->createView();


    $result = array(array(), array());

    $result['forms'][$id] = $forms[$id];
    $result['views'][$id] = $forms_views[$id];


    if (sizeof($message->getReplies())) {

        foreach ($message->getReplies() as $reply) {

            $child = $this->genReplyForms($reply);

            $result['forms'] = $result['forms'] + $child['forms'];
            $result['views'] = $result['views'] + $child['views'];

        }

    }

    return $result;
}

MessageReplyType 只需要用户输入。其他一切都在 Controller 中处理

        $builder
        ->add('title')
        ->add('content', 'textarea')
    ;

此外，我的简化 Twig 。我也简化了宏调用。正在为第一条消息执行不必要的 foreach 循环，而不是简单地将其传递给宏。

   {% macro displayReply(reply, forms) %}
    {% import _self as macros %}


    {# <li> id: {{ reply.id }} </li>
    <li> sent by: {{ reply.sender }} </li>
    <li> title: {{ reply.title }} </li>
    <li> content: {{ reply.content }} </li>
    <li> date: {{ reply.sentAt|date('d-m-Y H:i:s') }} </li>
    <a  href="{{ path('private_message_new',{'msg':reply.id}) }}">  reply  </a>
    <hr> #}
    <div class="panel panel-default">
        <div class="panel-body">
            <div class="message-info">
                <input type="hidden" name="messageid" id="messageId" value="{{ reply.id }}">

                <div class="message-title clearfix">
                    <h4 class="pull-left">{{ reply.title }}</h4>

                <hr class="lite-line">
                <div class="message-sender clearfix">
                    <div class="pull-left sender">

同样，我仍在寻找更好或更有效的替代方案，所以请发布它们。
