namespaces as "scope :module"

Hello!

I've got Gallery resource with namespaces:
/gallery/galleries_controller.rb
/gallery/albums_controller.rb
/gallery/photos_controller.rb
and models Gallery::Gallery, Gallery::Album and Gallery::Photo in my /
models/gallery/ folder

I want my Gallery work like standart resource: site.com/galleries/2/
albums/3, but being incapsulated in own folders, so i write in
routes.rb this rules:

scope :module => "gallery" do
  resources :galleries do
    resources :albums
  end
end

And then i've trouble using, i.e.

@gallery = Gallery::Gallery.find(1);
redirect_to(@gallery);

undefined method `gallery_gallery_url'

-- but why `gallery_gallery_url' when i expect just `gallery_url' like
it is in "rake routes"?

next time i write
<% @gallery = Gallery::Gallery.find(1); %>
<%= form_for @gallery do |f| %>

undefined method `gallery_galleries_path'

-- i need to manualy add :url option:
<%= form_for @gallery, :url => galleries_path do |f| %>

What's wrong? What i have to do with this issue?
Thanks for any help!

Spent a few hours looking through RoR sources and seems like i found
some kind of solution:
If we override property @_model_name in our models we can strip out
"Gallery::" from it:

class Gallery::Gallery < ActiveRecord::Base
  @_model_name = Gallery.model_name(self)
end

And in module:

module Gallery
  def self.table_name_prefix
    'gallery_'
  end

  def self.model_name(klass)
    @_model_name = ActiveModel::Name.new(klass, false,
klass.name.sub("Gallery::", ""))
  end
end

And it works! Now "form_for(@gallery)" and "link_to(@gallery)" use
"galleries_path" for action instead of non-existent
"gallery_galleries_path"

The only thing i want to know now is - am i criminal now after doing
theese practices?
Is it legal to override this property for this reason?
Thank you.
