What is the design pattern for subclassing a model?

Question

I have a model:

class Item < ActiveRecord::Base 

The item has the 'store' property

Based on the value of the store, I would like the Item object to have different behavior for certain methods.

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

Answer 1

Usually through Single Page Inheritance .
