nested resources with nested controllers

Is there a way to create resources that work with nested controllers? For example:

./script/generate scaffold_resource project name:string mkdir app/views/layouts/project # so the command below doesn't complain ./script/generate scaffold_resource project::user name:string

# routes.rb map.resources :projects do |project|   project.resources :users end

After creating a project and trying to list it's users by using /projects/1/users it will give the error:

Processing ApplicationController#index (for at 2007-01-10 20:31:39) [GET]   Session ID: effe3a9a1b3131e75c4507fc92eb01d5   Parameters: {"project_id"=>"1", "action"=>"index", "controller"=>"users"}

NameError (uninitialized constant UsersController): //vendor/rails/activesupport/lib/active_support/dependencies.rb:267:in 'load_missing_constant' # etc

Looking in rails/railties/lib/rails_generator/generators/compon ents/scaffold_resource/scaffold_resource_generator.rb there seems to be some logic for nesting controllers but I can't figure out how it is supposed to be used.
