Rails - Aug 2005 - using modules with models?

I''m trying to figure out how to use modules with my model classes. 
I''m going to have good number of model classes that don''t map
to the
database, and I''d like to put some of these in seperate modules. 
I''ve
been wrestling with this for 2 days and can''t figure out how to get it
to work.  Rails seems to handle it fine for controllers, though.

I tried creating a class SomeModule::SomeClass.  I have a file named
''some_class.rb'' in app/models/some_module.  I keep getting
this:

/usr/lib/ruby/gems/1.8/gems/activesupport-1.1.1/lib/active_support/dependencies.rb:186:in
`const_missing'': uninitialized constant SomeClass (NameError)

So, I tried creating a file called ''some_module.rb'' in
app/models that had this:

require_dependency ''some_module/some_class''

that seemed to work unless I have a class named SomeClass without a
module name, which kind of defeats the purpose of modules.

So, is there any way I can get this to work, or should I put all this
code in lib instead?

require_dependency, like require requires the name of the file, not a 
class in the file

so, in the controller add

require_dependency ''some_module''

class BogusController < ApplicationController


  def index
    test = SomeModule::SomeClass.new
    render(:text => test.hello)
  end

end


in file: lib/some_module.rb

module SomeModule
 
  class SomeClass

     def hello
       "hello"
      end
  end
end
