title: Rails: Use helper_method from one controller in another
body: <p>I have the following controller:</p>
  
  <pre><code>class FirstController &lt; ApplicationController
    helper_method :contoller_method
  
  private 
    def contoller_method
      "text"
    end
  end
  </code></pre>
  
  <p>How can I use <code>contoller_method</code> in the view of another controller? Is there a best practice?</p>
