Two approaches to interfaces in Ruby:

First aproach

Using inheritance in a cleaner way. It allows abstract classes, but needs a custom inheritance chain and only supports 1 interface.

module Interface
  attr_accessor :is_abstract
  
  def abstract

Imagine this case:

class Account < ActiveRecord::Base
  def transfer(other, quantity)
    tries = 0
    begin
      tries += 1
      transaction do
        self.quantity -= quantity
