无法在评论Laravel 5.7下显示我的回复

Question

我无法在每个评论下显示我的回复。这是我的代码...

评论模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Comment extends Model
{
    public function commentable()
    {
        return $this->morphTo();
    }

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

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

发布模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $fillable = [
        'user_id', 'topic', 'body', 'category',
    ];

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

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

评论控制器

<?php

namespace App\Http\Controllers;

use App\Comment;
use App\Post;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class CommentController extends Controller
{
    public function store(Request $request, $post)
    {
        $comment = new Comment;
        $comment->body = $request->body;
        $comment->user_id = Auth::user()->id;
        $post = Post::find($post);
        $post->comments()->save($comment);

        return back();
    }

    public function replyStore(Request $request, $comment)
    {
        $comment = new Comment;
        $comment->body = $request->body;
        $comment->user_id = Auth::user()->id;
        $comment = Comment::find($comment);
        $comment->comments()->save($comment);

        return back();
    }
}

路线

Route::post('/comment/store/{post}', 'CommentController@store')->name('comment.add');
Route::post('/reply/store/{commentid}', 'CommentController@replyStore')->name('reply.add');

我已经用parent_id创建了普通表，但是我不知道如何显示每个评论的回复。拜托，任何可以帮助我的人-我受困于此，第二个控制器函数的错误来自replystore（），该函数说它无法识别comments()方法。请帮我显示答复。
