ruby-on-rails - 如何在 Rails 3 中的 reset_session 命令之后找到新的 session_id？

Question

我按照 here 使用命令“reset_session”以避免 session 固定。

运行命令后，我想将新生成的 session_id 存储在数据库中，但 session[:session_id] 未定义。

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

两个连续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
Processing by WelcomeController#index as HTML
Rendered welcome/index.html.erb within layouts/application (1.9ms)

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
Processing by WelcomeController#index as HTML
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 session 未显示新 session ID。

我认为新的 session 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。
