modules and models

Hi,
I am trying to namespace my models in a Rails app.
I put this in routes

  map.namespace(:property) do |property|
    property.root :controller => :venues, :active_scaffold =>
true
    property.resources :location_groups, :active_scaffold =>
true
  end

and this in app/controllers/property/venues_controller

module Property
  class VenuesController < ApplicationController
    active_scaffold Venue
  end
end

this in app/modesl/property/venue

module Property
  class Venue < ActiveRecord::Base
    has_many :location_groups
  end
end

this for app/controllers/property/location_groups_controller

module Property
  class LocationGroupsController < ApplicationController
    active_scaffold LocationGroup
  end
end

and this for app/modesl/property/location_group

module Property
  class LocationGroup < ActiveRecord::Base
    belongs_to :venue
  end
end

now if I try to load http://localhost:3000/property/location_groups/new

I get
ActionView::TemplateError (Could not find
Property::Property::VenuesController or
Property::Property::VenueController)

I am confused as to how to do this correctly... any ideas?
Am I correct to do this? I don't want all my models in one folder... I
want to "package" them.
