ActiveRecord::MultiConditions

MultiConditions is a simple ActiveRecord plugin for storing ActiveRecord query conditions and make complex queries painless.

Discontinued Project

As of April 2009, I decided to discontinue the development of this library to concentrate my efforts on other projects.

If you are looking for a good alternative, I encourage you to have a look at Ben Johnson's SearchLogic library.
SearchLogic provides all ActiveRecord::Multiconditions features along with many other cool stuff.
