Singleton virtual model (Rails 3)

Question

Hi,

I would like to write a singleton virtual model (using Rails 3).

Here is my code:

class App
  extend ActiveModel::Naming
  include ActiveRecord::Associations
  include ActiveRecord::Reflection

  has_many :users

  def self.name
    'MyApp'
  end
end

But that's not enough. If for instance I try this in Rails console:

> App.first

I get this raised message:

NoMethodError: undefined method `first' for App:Class from (irb):1

Edit

I would also and especially be able to do this:

> App.first.users

Thank you for any ideas.
