How to implement data modification in the database in a background task?

Question

I know it's done with celery but don't know how to use it :(
PS Django 2+

Answer 1

Celery allows you to run arbitrary code in another process.

import django
django.setup() 

@app.task
def do_something():
    pass

Actually everything you need to start using celery. About the setting is well written in the documentation.
