I had a unique instance where I needed a model called “MRA”. When I
built my scaffolded resource I get the following:
mwilliams@Danzig:~/Documents/Projects/TestApp$ ruby script/generate
scaffold MRA
exists app/models/
exists app/controllers/
exists app/helpers/
create app/views/mr_as
exists app/views/layouts/
exists test/functional/
exists test/unit/
exists public/stylesheets/
create app/views/mr_as/index.html.erb
create app/views/mr_as/show.html.erb
create app/views/mr_as/new.html.erb
create app/views/mr_as/edit.html.erb
create app/views/layouts/mr_as.html.erb
create public/stylesheets/scaffold.css
create app/controllers/mr_as_controller.rb
create test/functional/mr_as_controller_test.rb
create app/helpers/mr_as_helper.rb
route map.resources :mr_as
dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
create app/models/mra.rb
create test/unit/mra_test.rb
create test/fixtures/mras.yml
create db/migrate
create db/migrate/20080614234404_create_mras.rb
mwilliams@Danzig:~/Documents/Projects/TestApp$
Notice how it handled the controller and views file names. It split
the name of the Model because (I’m making an assumption) that it’s
treating the model like a name. So “Mr.” or “Mrs.”.
What’s worse, is if I try to continue working, I can’t create any more
scaffolded resources

It even breaks migrations:

(in /home/mwilliams/Documents/Projects/TestApp)
rake aborted!

Is this a bug or is it breaking convention creating a model of all
capital letters (thought my case for creating an MRA model seems
legit).
I’ve created a ticket for the bug. Feel free to chime in or build a
patch (I may attempt to do so).
