如何将特定用户的通知标记为已读并在laravel 5中发布?

[英]How to mark notification as read for particular user and post in laravel 5?

我想将查看特定帖子的用户的通知标记为已读

public function show(Post $post)
    {

        $notification_for_user = auth()->user()->unreadNotifications()->where("data['post_id']", $post->id)->first()->update(['read_at' => now()]);

        return view('post.show', compact('post'));
    }

它给出了这个错误

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'data['post_id']' in 'where clause' 

因此,如何在显示数据列时访问数据列的post_id来删除该特定通知。

这就是它存储在数据列中的方式

{"post_id":8,"title":"Example Post...}

在web.php中:

Route::get('/read/notifications', 'Admin\\NotificationController@readNotification');

在控制器中:

public function readNotification() {
$user = Auth::user();
$user->unreadNotifications()->update(['read_at' => now()]);
}

请检查以下代码。

use Illuminate\Notifications\DatabaseNotification;

    $notification = DatabaseNotification::find( $request->notification_id );
                $notification->update(['read_at' => now()]);
                $notification->save();
