I liked subdomain but I didn’t want to have to pass it in each time I used the plugin methods. Maybe this is a bad example as there are a crap load of really easy solutions to this problem (migration, change plugin, etc.) but I just used alias_attribute. The method was introduced way back in 1.2 and even made it into err’s rails advent calendar but I’ve never needed it until now. class Account < ActiveRecord::Base alias_attribute :username, :subdomain end Now, even though the column in the database is subdomain, the method username and username= work just like subdomain.
