acts_as_sanitiled

https://github.com/dasil003/acts_as_sanitiled

A modernized version of Chris Wansthrath's venerable acts_as_textiled. It automatically textiles and then sanitizes columns to your specification. Ryan Grove's excellent Sanitize gem with nokogiri provides the backend for speedy and robust filtering of your output in order to: restrict Textile to a subset of HTML, guarantee well-formedness, and of course prevent XSS.
