You don’t. You extract the common code into a third piece. Either an
object that is instantiated in each of the controllers or a mixin
module that is included in each.

Thanks for the reply,

Where in my rails structure do I put this common code directory wise?
Somewhere in the app director?

Is there some tutorial on this?

You can.

class ApplicationController < ActionController::Base
helper_method :current_user, :logged_in?
end

This will make the ‘current_user’ and ‘logged_in?’ controller methods
available to all views.

There may be a more official way to do this, but what I’ve done is to
create a file ‘application.rb’ in the controller directory and put
shared functions in there. Works nice for validation or db queries etc.

I do the same for views / helpers by using a application_helper.rb file.
