[11.x] Allow readAt method to use in database channel

[utsavsomaiya]

Sometimes, you may want to create only the markedAsRead notification in the database driver.

To achieve this, follow these steps:

Before

1. First way:

protected $listen = [
    \Illuminate\Notifications\Events\NotificationSent::class => [
        \App\Listeners\NotificationSentListener::class,
    ],
];

class NotificationSentListener
{
    public function handle(NotificationSent $event)
    {
        // Check if the notification was sent via the database channel
        if ($event->channel === 'database') {
            $notification = $event->notification;
            
            // The notification instance may not have an ID directly,
            // as the event is triggered after being sent to channels.
            // However, you can query the database using known data.
            
            // Mark the notification as read
        }
    }
}

2. Second way:

• Overwrite the buildPayload method, and whenever the service container requires DatabaseChannel, provide the overridden channel!

After

// In your notification
public function readAt(): Carbon
{
    Carbon::now();
}
