在 laravel 如何将额外的数据传递给 mutators 和 accessors

What I'm trying to do is to append the comments of each article to the articles object, but the problem is that I need to request different number of comments each time.

出于某种原因，我需要使用mutators，因为有时我请求50篇文章，而我不想遍历结果并附加 comments .

那么，是否有可能执行以下操作，以及如何传递额外的参数.

This the Model:个

    class Article extends Model
    {

        protected $appends = ['user', 'comments', 'media'];

        public function getCommentsAttribute($data, $maxNumberOfComments = 0)
        {
            // I need to set maxNumberOfComments
            return $this->comments()->paginate($maxNumberOfComments);

        }
    }

Here is the controller:

class PostsController extends Controller
{


    public function index()
    {
        //This will automatically append the comments to each article but I
        //have no control over the number of comments
        $posts = Post::user()->paginate(10);
        return $posts;
    }    

}

What I don't want to do is:个

class PostsController extends Controller
{


    public function index()
    {

        $articles = Post::user()->all();

        $number = 5;
        User::find(1)->articles()->map(function(Article $article) {
            $article['comments'] = $article->getCommnets($number);
            return $article;
        });

        return Response::json($articles);
    }    

}

有更好的方法吗？因为我经常用这个，但它不合适.
