HTML Purifier equivalent for Ruby on Rails?

Question

Has anyone encountered an equivalent to HTMLPurifier for Rails apps? Essentially I need to clean up often terribly formed HTML generated by users before saving to the DB.

Answer 1

You can use the sanitize method.

sanitize(html)

There is also a Sanitize gem.

Sanitize.clean(html)

I tend to prefer the Sanitize gem because it can be used as a before_save filter in your models instead of having to use the sanitize method in each of your views.
