Models and controllers organized under module with same name

Howdy,

I would like to group related controllers within a
module, and have related models under a module of the
same name. I start off with the model:

micand@coconut ~/dev/projects/tmp $ script/generate
model Container::Model
create app/models/container
create test/unit/container
create test/fixtures/container
create app/models/container/model.rb
create test/unit/container/model_test.rb
create test/fixtures/container/models.yml

Seems easy enough, but all does not work as it should.

micand@coconut ~/dev/projects/tmp $ script/console
Loading development environment.

Container::Model
NameError: uninitialized constant Container
from
/usr/lib/ruby/gems/1.8/gems/activesupport-1.2.3/lib/active_support/dependencies.rb:200:in
`const_missing’
from (irb):1

To fix this, I create app/models/container.rb with the
following contents:

module Container end
require_dependency File.join(File.dirname(FILE),
‘container’, ‘model’)

Sweet success!

micand@coconut ~/dev/projects/tmp $ script/console
Loading development environment.

Container::Model
=> Container::Model

The problem comes after I add the controller. Creation
works fine:

micand@coconut ~/dev/projects/tmp $ script/generate
controller Container::
Controller
create app/controllers/container
create app/helpers/container
create app/views/container/controller
create test/functional/container
create
app/controllers/container/controller_controller.rb
create
test/functional/container/controller_controller_test.rb
create
app/helpers/container/controller_helper.rb

But it is no longer possible to refer to the model
class.

micand@coconut ~/dev/projects/tmp $ script/console
Loading development environment.

Container::Model
NameError: uninitialized constant Model
from
/usr/lib/ruby/gems/1.8/gems/activesupport-1.2.3/lib/active_support/dependencies.rb:195:in
const_missing' from /usr/lib/ruby/gems/1.8/gems/activesupport-1.2.3/lib/active_support/dependencies.rb:72:in const_missing’
from (irb):2

It seems having a controller module with the same name
as a model module somehow defeats Rails’ automatic
require()'ing of needed model files. Adding “require
File.join(RAILS_ROOT, ‘app’, ‘models’, ‘container’)”
to environment.rb doesn’t resolve this issue, as the
forced inclusion of the model module forces out the
controller module:

micand@coconut ~/dev/projects/tmp $ script/console
Loading development environment.

Container::Model
=> Container::Model
Container::ControllerController
NameError: uninitialized constant ControllerController
from
/usr/lib/ruby/gems/1.8/gems/activesupport-1.2.3/lib/active_support/dependencies.rb:200:in
`const_missing’
from (irb):2

Is there any way to have models and controllers
co-exist within a module of a particular name, or is
the only option to give different names to the module
housing the controllers and the module housing the
models?

Thanks,

Jeff
