So, I''ve been working with Rails for quite a while, but pretty new to actually digging in and patching/plugging the actual source methods of Rails modules. I''m trying to use ActiveRecord to create some Ruby wrappers for a couple API''s, but having to patch/rewrite so many of the ActiveResource methods to fit each particular API (not necessarily ActiveResource-compatible API''s mind you). It''s getting to the point that I''m wondering if it''s even worth it to try using ActiveResource. Anyway, I was wondering if there is any quick/easy way of using ActiveRecord''s Dirty module with ActiveResource, so that I can use methods such as "Person.changed?", etc. with ActiveResource objects. Has anyone tried this, or does anyone see any huge hurdles to attempting this? I''ve tried just doing this: require ''rubygems'' require ''activeresource'' require ''active_record/dirty'' And then I have: class Base < ActiveResource::Base ... class MyObject < Base ... end end Now how do I actually try attaching the "Dirty" methods to my objects, which are inheriting from ActiveResource::Base?
