Q:

Laravel eloquent model query for `not null`

I've been using Laravel for a project and using the Eloquent models to grab the model instances I need.
However, it doesn't look like there's a way to query for not null values.
https://laravel.com/docs/5.4/eloquent#retrieving-models
Is there a way to do something like this, where I want to get all Flight models where the ticket_id is not null?
$flight = App\Flight::where('ticket_id', '!=', null);

A:

Try this 
$flight = App\Flight::whereNotNull('ticket_id')->get();
