NoMethodError in Blog postsController#index

undefined method `devise' for User:Class

gistfile2.txt

All of the configuration is by the book. Nothing special, just defaults. 
Everything in the app works except for the user model -- other models are just fine. 

The mongoid.rb file is being loaded by devise correctly. It seems that the Devise::Models module is never being included into Mongoid::Document::ClassMethods

I have not defined any field on the user model, just trying to get Devise to load first.

Using bundler to manage gems, rails 2.3.5.

mongoid.rb

module Devise
  module Orm
    module Mongoid
      def self.included_modules_hook(klass, modules)
        klass.send :extend,  self
        yield

        modules.each do |mod|
          klass.send(mod) if klass.respond_to?(mod)
        end
      end

      include Devise::Schema

      # Tell how to apply schema methods. This automatically converts DateTime
      # to Time, since MongoMapper does not recognize the former.
      def apply_schema(name, type, options={})
        return unless Devise.apply_schema
        type = Time if type == DateTime
        field name, {:type => type}.merge(options)
      end
    end
  end
end
 
Mongoid::Document::ClassMethods.send(:include, Devise::Models)

user.rb

class User
  include Mongoid::Document
  devise :authenticatable
end
