rubygem-ransack

Successor to the MetaSearch gem

Ransack is a rewrite of MetaSearch created by Ernie Miller and maintained by Ryan Bigg, Jon Atack and a great group of contributors. While it supports many of the same features as MetaSearch, its underlying implementation differs greatly from MetaSearch, and backwards compatibility is not a design goal. Ransack enables the creation of both simple and advanced search forms for your Ruby on Rails application (demo source code here). If you're looking for something that simplifies query generation at the model or controller layer, you're probably not looking for Ransack (or MetaSearch, for that matter). Try Squeel instead.
