我正在使用 Ruby on Rails 2.3.5 和 Ruby 1.9 并使用 Authlogic 作为我的身份验证引擎。Authlogic 工作正常。但现在我一直在尝试使用以下教程来实现密码重置：http:
//www.binarylogic.com/2008/11/16/tutorial-reset-passwords-with-authlogic/
但是当我输入 mysite.com/password_resets/new 时出现以下异常
Processing PasswordResetsController#new (for 127.0.0.1 at 2010-03-13 01:09:45) [GET]

老实说，我不确定从哪里开始调试。是因为我使用的是 Ruby 1.9 吗？有些人似乎在使用 Authlogic 和 Ruby 1.9 时遇到问题：http:
//isitruby19.com/authlogic
请告诉我如何解决/调试这个问题？
谢谢，
谭
