如何在Rails 3中的reset_session命令之后找到新的session_id？

Question

我使用命令"reset_session"按照这里以避免会话固定.

运行该命令后,我想将新生成的session_id存储在数据库中,但未定义会话[:session_id].

我写了一个简单的测试:

class ApplicationController < ActionController::Base
  protect_from_forgery
  after_filter :after_test
  def after_test
    RAILS_DEFAULT_LOGGER.debug "Old Session: #{session.inspect}"
    reset_session
    session[:random_number] = ((rand*1000).to_i)
    RAILS_DEFAULT_LOGGER.debug "New Session: #{session.inspect}"
  end
end

两个conescutives页面加载的日志结果是:

Started GET "/" for 127.0.0.1 at 2011-04-16 11:42:57 +0200

New Session: {:random_number=>172}
Completed 200 OK in 7ms (Views: 6.4ms | ActiveRecord: 0.0ms)

和

Started GET "/" for 127.0.0.1 at 2011-04-16 11:42:58 +0200

Rendered welcome/index.html.erb within layouts/application (2.0ms)

New Session: {:random_number=>497}
Completed 200 OK in 7ms (Views: 6.4ms | ActiveRecord: 0.0ms)

如您所见,随机数(172)已正确传递到第二页,但新会话未显示新的会话ID.

我认为新的会话ID("54f46f520c80044a9f5475af78a05502")是在"after_filter"之后生成的,但我不知道如何检索它.

是的，rails有这个问题。有一张票 - https://rails.lighthouseapp.com/projects/8994/tickets/2200-session-support-broken

正如你所看到的，它还没有得到解决。
