Rails Ruby on Rails

Generating a scaffold resource that begins with the characters "MR" wrongfully creates its associated files.

Example)

ruby script/generate scaffold MRA

exists app/models/

exists app/controllers/

exists app/helpers/

*strong*create app/views/mr_as*strong*

exists app/views/layouts/

exists test/functional/

exists test/unit/

exists public/stylesheets/

*strong*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*strong*

create public/stylesheets/scaffold.css

*strong*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*strong*

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/20080613145050_create_mras.rb

As you can see above, the generator broke up the resources name with an underscore. This also prevents any further models from being generated. See below.

My assumption is that it's interpreting the string and seeing "MR" and treating that in some way as a persons title (which is why it breaks up the views to mr_a). The same thing happens when you generate a resource called "MRSTest".

This may be a feature I'm unaware of or that the convention is to not use all capital letters for a resource but in my case, I'm working with objects that happen to be called "MRAs".

I'd like to contribute so if I can come up with a patch over the weekend with some tests I will certainly attempt to do so.
