Subject: How to create and use a module?

Hi,

I am quite new to ruby and ruby on rails. I am trying to user helper
module in my controller but fail :( I added languages_helper.rb file to
helpers directory in my RoR app. The file looks like this:

module LanguagesHelper

  def LanguagesHelper.sort_to_first(langs, lang)
    ...my secret method here...
  end

end

Then I want to use it in LanguagesController. I put

require "languages_helper"

right in the beginning of the class body, and then in one of
controller's methods I try to do

ordered_langs = LanguagesHelper.sort_to_first(all_langs, lang)

When while browsing I come to this place in my browser, there is a message:

undefined method `sort_to_first' for LanguagesHelper:Module

What is wrong?

Best regards
