If I have a String like "DistributionMethod" is there any helper out
there that will turn it into "distribution_method" ?

I'm sure there's one out there, but for simple cases...

s = "SomeCamelCase"
s.scan(/.*?[A-Z].*?[^A-Z]*?/).map {|w| w.downcase}.join("_")

Check out the English library (require 'english/style').

http://english.rub...

Also, Facets and ActiveSupport have such methods.

The method names to look for are #snakecase, #underscore, and
#methodize.
