has_many_booleans is an ActiveRecord plugin which generates virtual boolean attributes for a model. When the object gets saved, the plugin transforms all attributes into a single integer, using a bitset. So you can easily add new attributes without changing the database structure. http://github.com/janlelis/has_many_booleans -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
