ACL9 和 Rails 2.3.8 - NameError: 未初始化的常量 User::Role答案

【问题描述】：

我正在运行 RVM（Ruby 1.8.7-head，Rails 2.3.8）并且正在运行一个新应用程序的基础知识。我有 Authlogic 工作，用最少的代码来工作。我正在尝试使用 ACL9（我正在处理不同的项目，相同的 RVM gemset）

class User < ActiveRecord::Base
    # authentication
  acts_as_authentic
  
  # authorization
  acts_as_authorization_subject
  
  def full_name
    "#{self.first_name} #{self.last_name}"
  end
end

当我尝试运行一个简单的检查以确保 ACL9 正常工作时...

脚本/控制台

u = User.first

u.has_role?(:anyrole)

我收到此错误...

ruby-1.8.7-head > u.has_role?(:anyrole)
NameError: uninitialized constant User::Role

我不确定为什么这适用于我拥有的所有其他应用程序，但不是这个 - 我不确定错误消息在说什么.. 感谢任何帮助。
