Question

我正在使用Laravel Commentable包，它使用嵌套集模式和Baum。

我设法允许用户对帖子发表评论，但他们没有线程，每条评论在数据库中都设置为depth。

所以我想知道如何制作像reddit这样的多线程评论？

这些是我的表

users: id, name, email...
posts: id, user_id, subreddit_id...
comments: id, body, parent_id, lft, rgt, depth, commentable_id, commentable_type, user_id

我的模特（评论和用户）

class Comment extends Model
{
    use Commentable;

    public function commentable()
    {
        return $this->morphTo();
    }

    public function user() {
        return $this->belongsTo('App\User');
    }

    public function posts() {
        return $this->belongsTo('App\Post');
    }
}

class User extends Model implements AuthenticatableContract, AuthorizableContract, CanResetPasswordContract
{
    use Authenticatable, Authorizable, CanResetPassword;

    public function posts() {
        return $this->hasMany('App\Post');
    }

    public function comments() {
        return $this->hasMany('App\Comment');
    }
}

这就是我在PostsController

中提交评论的方式

public function createComment($id) {

    $post = Post::with('user.votes')->with('subreddit.moderators')->where('id', $id)->first();

    $comment = new Comment;
    $comment->body = Input::get('comment');
    $comment->user_id = Auth::id();

    $post->comments()->save($comment);
}

这是视图

    <div class="post-comments">

    {!! Form::open(['route' => ['comment', $post]]) !!}
        <div class="form-group">
            <label for="comment">Your Comment</label>
            <textarea name="comment" class="form-control" rows="3"></textarea>
        </div>
        <button type="submit" class="btn btn-default">Send</button>
    {!! Form::close() !!}

    <div class="comments-nav">
        <ul class="nav nav-pills">
            <li role="presentation" class="dropdown">
                <a class="dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">
                    there are {{ count($comments) }} comments <span class="caret"></span>
                </a>
                <ul class="dropdown-menu">
                    <li><a href="#">Best</a></li>
                    <li><a href="#">Hot</a></li>
                </ul>
            </li>
        </ul>
    </div>

    <div class="row">

        <div class="media">
            <!-- first comment -->
            @foreach($comments as $comment)
            <div class="media-heading">
                <button class="btn btn-default btn-xs" type="button" data-toggle="collapse" data-target="#{{ $comment->id }}" aria-expanded="false" aria-controls="collapseExample"><span class="glyphicon glyphicon-minus" aria-hidden="true"></span></button> <span class="label label-info">12314</span> {{ $comment->user->name }} 12 hours ago
            </div>

            <div class="panel-collapse collapse in" id="{{ $comment->id }}">

                <div class="media-left">
                    <div class="vote-wrap">
                        <div class="vote up">

Answer 1

我还没有使用Laravel Commentable包，但docs看起来还不错。

我认为您的use Commentable;型号需要Post而不是Comment型号。

您的Comment模型似乎需要延伸Baum\Node而不是Model

然后你应该工作。

$post = Post::with('user.votes')->with('subreddit.moderators')->where('id', $id)->first();

$comment = new Comment;
$comment->body = Input::get('comment');
$comment->user_id = Auth::id();

$post->comments()->save($comment);

// or you could do 

$comment->makeChildOf($post);

要对评论发表评论，看起来你就是这样做的。我可能会制作一个CommentsController。

public function addComment(Request $request){
    $parent = Comment::find(Input::get('parent_id'));

    $comment = new Comment;
    $comment->body = Input::get('comment');
    $comment->user_id = Auth::id();

    $comment->makeChildOf($parent);
}

文档的Relations，Root and Leaf scopes，Accessing the ancestry/descendancy chain部分有几个关于如何检索评论评论的示例。

修改

看起来包中的Comment模型已经扩展了Baum \ Node，因此您不需要这样做。为了使用此包，您似乎需要使用他的Comment模型。我相信你可以使用他的模型作为基础并自己动手。

你可以这样做。你必须建立一条路线。

<div class="collapse" id="replyCommentT"> {!! Form::open(['route' => ['comment', $comment]]) !!} <input type="hidden" name="parent_id" value="{{ $comment->id }}"/> <div class="form-group"> <label for="comment">Your Comment</label> <textarea name="comment" class="form-control" rows="3"></textarea> </div> <button type="submit" class="btn btn-default">Send</button> {!! Form::close() !!} </div>
