I am implementing Laravel 5.3 Notifications at the moment which is working very nice.
At the moment I am using \'email\' as a notifications channel but I want to add
It's pretty simple, Just add protected $connection = 'YOUR CONNECTION NAME';
at Illuminate\Notifications\DatabaseNotification
That's all and it will work :)
You don't need to create new models if you are going to use one notification table with same connection.
My code will works if ur using different connection for USER model.
