Dheeraj is correct, helpers are intended for views, but if you have a
method that you need access to in your controller and your view, and/
or your helper then, in order to keep things a little DRYer, you can
define your method in your controller, and make it available to the
view and helper as so:
class MyController < ApplicationController
helper_method :my_method
private
def my_method
# do something
end
end
Now you can access my_method from your view or your helper as well as
your controller.
