If I can't put global methods in application.rb, where do I put them, and how do I call them? And shouldn't this work? Is there anyplace I can see where Rails is looking for this method?
Maybe you just need to give ruby an object to send this method to?
C:\rails\test>ruby script/console Loading development environment.
self.class
=> Object
msg
NameError: undefined local variable or method `msg' for #<Object: 0x284fa38> from (irb):2
a = ApplicationController.new
=> #<ApplicationController:0x48c3ad0>
a.msg
=> "msg"
