This means that an inheritance looking like this: class Company < ActiveRecord::Base; endclass Firm < Company; endclass Client < Company; endclass PriorityClient < Client; end When you do Firm.create(name: "37signals"), this record will be saved in the companies table with type = “Firm”. You can then fetch this row again using Company.where(name: '37signals').first and it will return a Firm object. Be aware that because the type column is an attribute on the record every new subclass will instantly be marked as dirty and the type column will be included in the list of changed attributes on the record.
