尽管已定义“未定义的变量”

Question

此视图应显示帖子的评论。尽管我已定义comments，但仍然收到以下错误：

  

未定义变量：注释（查看：C：\ xampp \ htdocs \ StuffSpot \ resources \ views \ dashboard.blade.php）

步骤如下：

1. 这是发生错误的行：

@foreach ($comments as $comment)

1. 以下是表单的路由：

<form action="{{route('comment.create')}}" method="post">

1. comment.create路线：

    Route::post('/createcomment', [
        'uses' => 'PostController@postCreateComment',
        'as' => 'comment.create',
        'middleware' => 'auth'
    ]);

1. PostCreateComment具有一些插入代码和以下内容：

return redirect()->route('dashcomment')->with(['message' => $message]);

1. dashcomment路线：

    Route::get('/dashcomment', [
        'uses' => 'PostController@getDashComment',
        'as' => 'dashcomment',
        'middleware' => 'auth'
    ]);

1. getDashComment函数：

    public function getDashComment()
    {
        $comments = Comment::orderBy('created_at', 'desc')->get();
        return view('dashboard', ['comments' => $comments]);
    }
