Question

我正在成功使用Authlogic，我正在尝试为用户添加using this tutorial重设密码的功能。当我提交请求（到PasswordResetsController #create动作）重置密码时，我收到此错误：

TypeError (can't convert nil into String):
  app/models/user.rb:19:in `deliver_password_reset_instructions!'
  app/controllers/password_resets_controller.rb:12:in `create'

我已经多次通过教程，并且已经梳理了sample app of it here。我似乎无法弄清楚发生了什么。任何人对此实施和错误都有任何经验/方向吗？

这是完整的终端输出：

User.rb

  def deliver_password_reset_instructions!
      reset_perishable_token!
      Notifier.deliver_password_reset_instructions(self)
    end

更新：我正在使用rails 2.3.8和ruby 1.8.7

更新： Notifier.rb

 default_url_options[:host] = "foobar.com"  

 def password_reset_instructions(user)  
  subject       "Password Reset Instructions"  
  from          "foobar"  
  recipients    user.email  
  sent_on       Time.now  
  body          :edit_password_reset_url => edit_password_reset_url(user.perishable_token)  
 end

更新：这是/views/notifier/password_rest_instruction.erb

A request to reset your password has been made. If you did not make this request, simply ignore this email. If you did make this request just click the link below:

<%= @edit_password_reset_url %>

If the above URL does not work try copying and pasting it into your browser. If you continue to have problem please feel free to contact us.
