I have a class called Duration that represents a unit of time. It has lots of time-related methods and an attribute that represents the duration in seconds. I want to store it in my db. I had a column type of NUMERIC, so if i save it, rails trys to coerce it to a float automagically and fails. I need to display it and store it as a number but treat it in the middle layer as a Duration so I can use all it's wonderful functionality. What's the right way to do this? thanks.

You want to use composed_of class UserOfDuration < ActiveRecord::Base composed_of :project_length, :class_name => 'Duration', :mappings => %w(duration_in_seconds duration) end http://api.rubyonrails.com/classes/ActiveRecord/Ag... Hope that helps !
