Usage

Call warhol_methods in an ActiveRecord class

class Artwork < ActiveRecord::Base
	warhol_methods
end

This will automatically save the last changes to the model in the cache or redis and be easily retrievable for viewing what's been changed.

Development

TODO

• Don't include updated_at as a change
• Ability to exclude or filter columns
• Show how the attribute changed. (From what to what)
• Easily check off changes and remove from memory
• Represent a group of attributes as one i.e paperclip/image attributes as 'avatar'
• Handle has many associations gracefully
• Switch to Rails.cache instead of Redis, or storage choice
