Yes, I know the irony of asking for help with a help controller. 
The intent here is to have a place to put common help messages, nothing complicated at the beginning at least. I created a help controller, but of course the rspec_scaffold generator called it, and the path generated, 'helps'. I tend to think /helps/... is a path that might indicate we need a better translator, so I added this to my routes.rb file:
  map.resources :help
This seems to have taken care of most of it. Since right now all the terms come from an internal, non-database-backed array, I have no need (currently) for the other methods, so I added :only => [:index, :show] to this. However, I also want an entry page which doesn't just list all possible status codes, I added :collection => { :all => :get } as well.
Now, this works, but it was a lot of manual renaming of files.
The question is, what are others doing for this sort of thing? /helps just seems so... wrong, but everything behind it would be RESTful. /help/ won't map into certain paradigms of automatic resource mapping, but I like it better for the user to see on the screen.
