Django: How to run a function when server exits?

Question

I am writing a Django project where several processes are opened using Popen. Right now, when the server exits, these processes are orphaned. I have a function to terminate

Answer 1

First of all "When the server quits" is ambiguous. Does this stuff run when responding to a request? Does this stuff run during a management command?

Let's assume for the sake of argument, that you are running this somewhere in a view, so you want to have something that runs after each view returns in order to clean up junk that the view left hanging around.

Most likely, what you are looking to do is to write some Middleware. Even more specifically, some sort of process_response.

However, based on the short description of what you have so far, it sounds far more likely that you should be using some task manager, such as Celery to manage asynchronous tasks and processes.
