Another uninitialized constant question


#1

Guys,

I’m trying to generate a scaffold to admin a table called hangars. I’d
like the controller to fall with an “admin” sub-module.

I used the command:

script/generate scaffold Hangar Admin::Hangar

This seemed to work, and placed the controller in
controllers/admin/hangar_controller.rb, where I expected to find it. It
also created the hangar.rb model in app/models/hangar.rb.

However, now I get (when trying to connect to admin/hangar):

NameError in Admin/hangar#index

uninitialized constant Hangar

This error occured while loading the following files:

Any ideas what I’ve done wrong?

Thanks!
