Title
Body
I'm writing a model that handles user input from a text area. Following the advice from http://blog.caboo.se/articles/2008/8/25/sanitize-your-users-html-input , I'm cleaning up the input in the model before saving to database, using the before_validate callback. The relevant parts of my model look like this: include ActionView::Helpers::SanitizeHelper class Post < ActiveRecord::Base { before_validation :clean_input ... protected def clean_input self.input = sanitize(self.input, :tags => %w(b i u)) end end Needless to say, this doesn't work. I get the following error when I try and save a new Post. undefined method `white_list_sanitizer' for #<Class:0xdeadbeef> Apparently, SanitizeHelper creates an instance of HTML::WhiteListSanitizer, but when I mix it into my model it can't find HTML::WhiteListSanitizer. Why? What can I do about this to fix it?
