Question

I tried doing the def index(*args); end; trick within the models I’d like cache_money to ignore, but to no avail.

Answer 1

commenting out index() will only turn off indexes for that object. But the default index by id will still run.

I have it working, but am in the process of getting the fix upstream.
http://github.com/kbrock/cache_money if you want to test it out before hand.
example:

class model < ActiveRecord:Base
  is_cache(false)
  #...
end

best of luck and let me know how it goes.
