title: How to access URL helper from rails module
body: <p>I have a module with a function. It resides in /lib/contact.rb:</p>
  
  <pre><code>module Contact
    class &lt;&lt; self
      def run(current_user)
        ...
      end
    end
  end
  </code></pre>
  
  <p>I want to access the URL helpers like 'users_path' inside the module. How do I do that? </p>
