渲染视图后，如何做一些事情？ （Django的） [英] How do you do something after you render the view? (Django)

问题描述

我使用

return render_to_response()

信号是唯一的方法吗？我需要写一个自定义信号，还是请求完成给我足够的信息？基本上我需要知道什么页面呈现，然后采取行动来回应。

Are signals the only way to do this? Do I need to write a custom signal or does request_finished give me enough information? Basically I need to know what page was rendered, and then do an action in response to that.

谢谢。

从注释更新：我不想压缩页面的渲染，所以我想先渲染页面，然后执行操作。

UPDATE FROM COMMENTS: I don't want to hold up the rendering of the page, so I want to render the page first and then do the action.

推荐答案

你产生一个单独的线程并让它执行操作。

You spawn a separate thread and have it do the action.

t = threading.Thread(target=do_my_action, args=[my_argument])
# We want the program to wait on this thread before shutting down.
t.setDaemon(False)
t.start()

导致'do_my_action（my_argument）'在第二个线程中执行，即使在发送Django响应并终止初始线程之后，该线程也将继续工作。例如，它可以发送电子邮件，而不会延迟响应。

This will cause 'do_my_action(my_argument)' to be executed in a second thread which will keep working even after you send your Django response and terminate the initial thread. For example it could send an email without delaying the response.
