Question

I’ve created a module in the /lib folder:

Module CookieHelper

   $str = cookies["shoppingcart"]

   def get_all_cookie_info()
   end

end

But this isn’t working. If I move the code into a controller it works fine.

Also, I’m trying to invoke the method within this module. I’ve tried:

  require CookieHelper
  CookieHelper::get_all_cookie_info()

Answer 1

CookieHelper::get_all_cookie_info is the correct way to call this method.

include CookieHelper
get_all_cookie_info

is another valid way, if you want include all of the methods in cookie helper available without having to namespace them (once the file lib/cookie_helper has been loaded).

What the issue probably is, is that the lib file isn’t even required yet, this is because rails3 doesn’t automatically load files in lib anymore. You can tell it to do so by editing your application.rb file, and setting inside class Application < Rails::Application

config.autoload_paths += %W( #{config.root}/lib )
