我做了评论功能，但它不起作用

Question

我做了评论功能，但它不起作用。它使POST数据包很好，但它不会对db进行任何查询。因此表格是空的。

以下是我的源代码

CommentController.php

<?php

namespace App\Http\Controllers; //171029

use Illuminate\Http\Request;
use App;

class CommentsController extends Controller
{
        public function __construct()
        {
                $this->middleware('auth');
        }
        public function store(\App\Http\Requests\CommentsRequest $request, \App\Article $article)
        {
                $comment = $article->comments()->create(array_merge(
                $request->all(), ['user_id'=> $request->user()->id]
                ));
                

                return redirect(route('articles.show', $article->id) .'#comment_'.$comment->id);
        }
}

CommentModel

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Comment extends Model
{
        protected $fillable = ['commentable_type', 'commentable_id', 'user_id', 'parent_id', 'content',];

        protected $with = ['user',];

        public function user()
        {
                return $this->belongsTo(User::class);
        }

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

        public function replies()
        {
                return $this->hasMany(Comment::class, 'parent_id')->lastest();
        }

        public function parent()
        {
                return $this->belongsTo(Comment::class, 'parent_id', 'id');
        }

质量分配
对于质量分配，您需要指定fillable或guarded。

You may also use the create method to save a new model in a single line. The inserted model instance will be returned to you from the method. However, before doing so, you will need to specify either a fillable or guarded attribute on the model, as all Eloquent models protect against mass-assignment by default.
