We can bind a class as a Singleton:
public function register()
{
App::singleton('my-database', function()
{
return new Database();
});
}
This way, the first time an instance of 'my-database' will be requested to the service container, a new instance will be created. Al...

Once a model object has been fetched, it becomes a fully realized instance of the class. As such, any additional methods can be accessed in forms and serializers (like Django Rest Framework).
Using python properties is an elegant way to represent additional values that are not stored in the databa...
While Value Converters can be comprised of either a toView or fromView method, in the below example we will be creating a basic Value Converter which just uses the toView method which accepts the value being sent to the view as the first argument.
