Rails - Jun 2010 - Controller and Scaffold Controller generator - plural vs. singular

Hello,

Why does:

*$ rails g controller project*
Generates *app/controllers/project_controller.rb*

and

*$ rails g scaffold_controller project*
Generates *app/controllers/projects_controller.rb* and *app/views/projects/*
?

With scaffold_controller there is even the following message at the end:
"Plural version of the model detected, using singularized version. Override
with --force-plural."

Using singularized version? What? Which model is he talking about? There are
no models in my (dummy) application.


Thanks for the attention,

This is by design. Consider:

$ rails g scaffold project name:string

You will notice an output containing something like:
invoke  active_record
      create    db/migrate/20100602201538_create_projects.rb
      create    app/models/project.rb
      invoke    test_unit
      create      test/unit/project_test.rb
      create      test/fixtures/projects.yml
       route  resources :projects
      invoke  scaffold_controller
      create    app/controllers/projects_controller.rb

Notice also the following line in the output:
      invoke  scaffold_controller

So, the scaffold_controller generator assumes the full MVC stack from 
model, through controller, to the views. In other words, running 
scaffold_controller assumes you already have a Project model and assumes 
the plural form that is the convention for controllers representing 
model objects.

$ rails g controller project

This makes no assumptions about anything and simply creates a controller 
file by appending _controller.rb to the name you supply to the 
generator.

Ah, thank you for your answer! :D

I was not sure about Ruby on Rails convention of naming controllers in
plural. :)
