我想在我的laravel应用程序中的帖子后添加评论。 我找到了这个我想要使用的包https://github.com/laravelista/comments。 我安装了它，并按照说明进行操作，现在我得到的问题是

类名必须是有效的对象或字符串（视图:C:\XAMPP\HTDOCS\LSAPP\Resources\Views\Vendor\Comments\Components\Comments.blade.php)

它向我展示了这段代码:

    {

        return tap(new $class, function ($instance) {

            if (! $instance->getConnectionName()) {

                $instance->setConnection($this->connection);

            }

        });

    }

这段代码不是我写的，而是我安装了前面提到的包后生成的。

我的post.php文件如下:

namespace TicketSystem;

use Illuminate\Database\Eloquent\Model;
use Laravelista\Comments\Commentable;

class Post extends Model
{
    use Commentable;
    protected $table = 'posts'; //default?
    public $primaryKey = 'id';
    public $timestamps = true; //default

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

我的user.php文件如下:

namespace TicketSystem;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\CanResetPassword;
use Laravelista\Comments\Commenter;

class User extends Authenticatable
{
    use Notifiable, Commenter;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function posts() {
        return $this->hasMany('TicketSystem\Post');
    }

    public function roles() {
        return $this->belongsToMany('TicketSystem\Role');
    }

    public function hasAnyRoles($roles) {
        return null !== $this->roles()->whereIn('name', $roles)->first();
    }

    public function hasAnyRole($role) {
        return null !== $this->roles()->where('name', $role)->first();
    }
}

在我想要添加注释的blade.php文件中:

<div>
     @comments(['model' => $post])
</div>

如何解决这个问题？ 我想了很多办法，但不是很成功。

编辑:comments.php文件:

return [

    /**
     * To extend the base Comment model one just needs to create a new
     * CustomComment model extending the Comment model shipped with the
     * package and change this configuration option to their extended model.
     */
    'model' => \Laravelista\Comments\Comment::class,

    /**
     * You can customize the behaviour of these permissions by
     * creating your own and pointing to it here.
     */
    'permissions' => [
        'create-comment' => 'Laravelista\Comments\CommentPolicy@create',
        'delete-comment' => 'Laravelista\Comments\CommentPolicy@delete',
        'edit-comment' => 'Laravelista\Comments\CommentPolicy@update',
        'reply-to-comment' => 'Laravelista\Comments\CommentPolicy@reply',
    ],

    /**
     * The Comment Controller.
     * Change this to your own implementation of the CommentController.
     * You can use the \Laravelista\Comments\CommentControllerInterface.
     */
    'controller' => '\Laravelista\Comments\CommentController',

    /**
     * Disable/enable the package routes.
     * If you want to completely take over the way this package handles
     * routes and controller logic, set this to false and provide your
     * own routes and controller for comments.
     */
    'routes' => true,

    /**
     * By default comments posted are marked as approved. If you want
     * to change this, set this option to true. Then, all comments
     * will need to be approved by setting the `approved` column to

     *

     *         'approved' => true
     *     ])
     *
     */
    'approval_required' => false,

    /**
     * Set this option to `true` to enable guest commenting.
     *
     * Visitors will be asked to provide their name and email
     * address in order to post a comment.
     */
    'guest_commenting' => false,

    /**
     * Set this option to `true` to enable soft deleting of comments.
     *
     * Comments will be soft deleted using laravels "softDeletes" trait.
     */
    'soft_deletes' => false

];

在PostsController文件中:

    * Display the specified resource.
    * 
    * @param int $id
    * @return \Illuminate\Http\Response
    */

   public function show($id)
   {
      $post = Post::find($id);
      return view('posts.show')->with('post', $post);
   }

   /**
    * Show the form for editing the specified resource.
    * 
    * @param int $id
    * @return \Illuminate\Http\Response
    */

   public function edit($id)
   {
      $post = Post::find($id);
      if (auth()->user()->id !== $post->user_id) {
         return redirect('/posts')->with('error', 'Unauthorized Page');
      }
      return view('posts.edit')->with('post', $post);
   }

dd($POST，$ID)显示:

  +primaryKey: "id"
