发布通知将用户重定向到发布ID

Question

我有数据库通知，每当他们单击通知链接之一时，我都试图重定向用户，它将转到确切的POST ID，然后将其标记为已读，即选中了该特定通知。但我无法使其工作

这是我的控制人

 public function readbyid($id){

    if(isset($notification->data['id'])){
        return redirect()->action(
            'PostController@show', ['id' => $notification->data['id']]
        );
    }else{
        return redirect()->back();
    }
} 

通知模型

 public function toArray($notifiable)
{
    return [
        'id' => $this->post->id,
    ];
}

刀片视图：

  <li class="nav-item dropdown"> <a id="messages" rel="nofollow" data-target="#" href="#" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" class="nav-link"><i class="fa fa-bell"></i>@if (auth()->user()->unreadnotifications->count())<span class="badge badge-warning">{{auth()->user()->unreadnotifications->count()}}</span>@endif</a>
              <ul aria-labelledby="notifications" class="dropdown-menu">
              <li><a rel="nofollow" href="{{Url('markread')}}" class="dropdown-item all-notifications text-center"> <strong> <i class="fa fa-bell"></i>Mark all as Read</strong></a></li>
              @foreach(auth()->user()->unreadnotifications as $notify)
                <li><a rel="nofollow" href="{{Url('markread/{id}')}}" class="dropdown-item d-flex"> 

                    <div class="msg-body">
                    <h3 class="h5">{{$notify->data['title']}}</h3>
                    </div> </a></li>@endforeach
              </ul>
            </li>

路线：

Route::get('markread/{id}', 'NotifyController@readbyid' );
