Question

//我收到以下错误： Builder.php第2345行中的错误异常：调用未定义的方法Illuminate \ Database \ Query \ Builder :: replies（）（查看：d：\ xampp \ htdocs \ myproject \ resources \ views \ homepost.blade.php）

//我试图在视图中查看（已批准的回复），但这不适用于我!!

在视图中：

 @if($posts)
        @foreach($posts as$post)

<p>No. approved replies={{$post->comments()->replies()->whereIsActive(1)->count()}}</p>
 <p>No. category={{$post->category()->count()}}


        @endforeach
    @endif

在Post控制器中：

       public function index()
       {
            $posts=Post::all();
            return view('Admin.posts.index',compact('posts'));
       }

在Post模型中：

        <?php

            namespace App;
            use Illuminate\Database\Eloquent\Model;

           class Post extends Model
        {

            protected $fillable=[
                'title','body','category_id','photo_id'
            ];

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

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

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

在评论模型中：

    <?php

    namespace App;

    use Illuminate\Database\Eloquent\Model;

    class Comment extends Model
    {

        protected $fillable=[
            'post_id',
            'photo',
            'author',
            'email',
            'body',
            'is_active'
        ];
        public function replies(){
            return $this->hasMany('App\CommentReply');
        }
        public function post(){
            return $this->belongsTo('App\Post');
        }
    }

在CommentReply模型中：

namespace App;

use Illuminate\Database\Eloquent\Model;

class CommentReply extends Model
{
    protected $fillable=[
        'comment_id',
        'is_active',
        'author',
        'photo',
        'email',
        'body'
    ];

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

}

尝试一下：

$post->comments()
->join(DB::raw('(Select comment_id,count(*) as total from CommentReply where is_active = 1 group By comment_id) as replies'),function($join){
    $join->on('comments.id', '=', 'replies.comment_id')
})
->selectRaw('sum(replies.total) as total_comments')
->get('total_comments');
