Background

I’m an absolute novice at all things development/code related.  
Masochisticly I’m trying to leanr Ruby on Rails. It took me an evening  
to work out that start\>run\>command launched something entirely different  
to start\>run\>cmd so this problem probably has an equally obvious  
solution.

PROBLEM

I am trying to set up a controller. the command

“ruby script/generate controller Site index about help”

seems to work fine. However although in the directory the files seem to  
have been created I can’t see them in my RadRails project window.

When I try and take a look at the controller using

“site\_controller.rb” or if I try and look at the application controller  
using “application.rb”

I get the error:

D:/ruby/rails\_space/app/controllers/application.rb:4: uninitialized  
constant ActionController

WHAT AM I DOING WRONG?
