Class alias in Ruby

ruby-on-rails ruby class alias

I am developing a new Rails app based on a similar existing one. In my old app, I have Coupon class, which is very similar to Ticket in my new app. I want to reuse all code in Coupon, but with a new class name.

Since refactoring is cumbersome in Rails, I wonder if there is a way to create alias for a class in Ruby (similar to alias for attributes and methods).

Classes don't have names in Ruby. They are just objects assigned to variables, just like any other object. If you want to refer to a class via a different variable, assign it to a different variable:

Foo = String
