在 Rails 3 中设置会话超时 [英] Setting session timeout in Rails 3

问题描述

这看起来很简单:我试图让我的 rails Active Record 会话在 2 分钟后超时.所以两分钟后，我希望我的用户必须重新登录.

This seems simple: I am trying to get my rails Active Record session to timeout after 2 minutes. So after two minutes I want my users to have to re-login.

我只是在我的本地开发机器上运行 rails server(即 WebBrick).

I'm just running rails server (i.e. WebBrick) on my local dev machine.

我知道这与 config/initalizers/session_store.rb 中的以下代码有关，但我认为我还没有完全掌握它:

I know this is something to do with the following code in config/initalizers/session_store.rb, but I don't think I have quite nailed it:

CodedOn::Application.config.session_store :active_record_store

CodedOn::Application.configure do
    config.action_controller.session = {:expire_after => 2.minutes}
end

这似乎不起作用，或者至少我的会话似乎没有超时.我找不到太多关于 Rails 3 的方法来做到这一点，因为我知道事情从 Rails 2.x 开始发生了变化.

This doesn't seem to work, or at least my session doesn't appear to timeout. I can't find much about the Rails 3 way to do this as I know things have changed from Rails 2.x.

有人可以帮我吗?

推荐答案

我认为您必须手动执行此操作，因为活动记录存储没有实现 expire_after 选项.所以在你的(我假设)过滤器之前，你应该这样做:

I think you will have to do this manually since the active record store does not implement the expire_after option. So within your (I assume) before filter, you should do this:

def authenticate
  if session[:logged_in]
    reset_session if session[:last_seen] < 2.minutes.ago
    session[:last_seen] = Time.now
  else
    ... authenticate
    session[:last_seen] = Time.now
  end
end

显然，这并不完整，但它应该为您提供基本概念.

Obviously, this is not complete, but it should give you the basic idea.

更新:

从 2.3 版开始，rails 中似乎存在该功能.我在这里找到了相关代码.这是 AbstractStore，它应该作为所有派生类的基类.因此，正如 dadooda 所建议的，以下应该有效:

It seems that the functionality IS present in rails since version 2.3. I found the relevant code here. This is AbstractStore which should serve as base class for all derived ones. So, as dadooda suggests, the following should work:

Some::Application.config.session_store :active_record_store, {
  expire_after: 24.hours,
}
