Can Django do multi-thread works?

Question

I have a question, that can Django do multi-thread works?

Here is what I want to do: click a button on a web page, then there are some functions in model.py starts

1. Yes it can multi-thread, but generally one uses Celery to do the equivalent. You can read about how in the celery-django tutorial.
2. It is rare that you actually want to force the user to wait for the website. While it's better than risks a timeout.

Here's an example of what you're describing.

User sends request
Django receives => spawns a thread to do something else.
main thread finishes && other thread finishes 
... (later upon completion of both tasks)
response is sent to user as a package.

Better way:

User sends request
Django receives => lets Celery know "hey! do this!"
main thread finishes
response is sent to user
...(later)
user receives balance of transaction
