Rails - What is the design pattern to subclass a model?

Question

I have a model:

class Item < ActiveRecord::Base

Item has a property 'store'

Based on the value of store, I'd like the Item object to have different behaviour for specific methods.

Is there a common design pattern for this in Rails? How is this done cleanly without a big if-else statement in the methods?

Answer 1

Usually through Single-Table Inheritance.
