RVM（Ruby 1.8.7-head、Rails 2.3.8）を実行していて、新しいアプリの基本を実行しています。私はAuthlogicを機能させており、それを機能させるための最小限のコードを使用しています。ACL9（別のプロジェクト、同じRVMジェムセットで作業しています）を使用しようとしています
class User < ActiveRecord::Base
# authentication
acts_as_authentic
# authorization
acts_as_authorization_subject
def full_name
"#{self.first_name} #{self.last_name}"
end
end
ACL9が正しく機能していることを確認するために、簡単なチェックを実行しようとすると...
スクリプト/コンソール
u = User.first
u.has_role？（：anyrole）
このエラーが発生します...
ruby-1.8.7-head > u.has_role?(:anyrole)
NameError: uninitialized constant User::Role

なぜこれが私が持っている他のすべてのアプリで機能するのかわかりませんが、これはそうではありません-そしてエラーメッセージが何を言っているのかわかりません..助けていただければ幸いです。
