This is essentially copied from the payment class. There’s an issue with how Rails auto-loads models, and finding out what classes have inherited from you.

A subclass For example, a subclass called WonkaPayment can call payment_method :wonka Then callers can instantiate a WonkaPayment by calling Payment.create :wonka

This will also define an instance method called “payment_method” on the subclass which will return a stringification of the symbol
