Best way to extract common methods

Modules are indeed a good way to do this. You could, as one poster
suggested, throw them all into application.rb. But you might find
that file getting big and unwieldy. An alternative is to group them
into a well-named module or set of modules and then to include those
modules in any controllers (or any other context) in which they're
needed. You could put the module in a file in, say, your lib/
directory, require that file in environment.rb and then where ever it
makes sense, do:

class MyController < ApplicationController
  include MyWellNamedModule
  def some_action
    some_method_which_counts_characters_in_a_string("a string")
  end
end

You called the method something different from the name you're using
to call it. I think you just made a simple mistake. Look closely at
the definition vs. what you're calling in the controller :slight_smile:
