Django每次成功登录都会运行一次代码

Question

How do I run a piece of code on django after a successful user login? I cannot put the code in the view that is shown after login for the following reasing:

• The redirect is dynamic, so the view after login differs. It depends on the page the user tried to access.
• I want to run my code only once, only right after the moment a user logs in.

I am looking for the most simple pythonic way to do this? Is it possible without writing my own authentication middleware?

Answer 1

I'm not sure why you can't put it in the view that processes the login itself. You've certainly written something that takes the output from the username/password form and calls auth.login(), so that would seem to be the right place to do it.

Alternatively, you could write a signal listener for the user_logged_in signal.
