Using sanitize within a Rails controller

ruby-on-rails controller helper sanitize

I'm trying to call sanitize within a controller. Here's what I tried:

class FooController < ApplicationController
  include ActionView::Helpers::SanitizeHelper
  # ...
end

However, I'm getting this error:

undefined method `white_list_sanitizer' for FooController:Class

I searched around and people recommended switching the include line to include ActionView::Helpers, but that results in this error:

undefined method `url_for' for nil:NilClass

What's the correct way to call sanitize? I'm using Rails 2.3.5.

you can use this ActionController::Base.helpers inside action method:

class SiteController < ApplicationController
  def index
    render :text => ActionController::Base.helpers.sanitize('<b>bold</b>')
  end
end

Hope this helps
