Django multiprocessing and database connections

Question

Background:

I\'m working a project which uses Django with a Postgres database. We\'re also using mod_wsgi in case that matters, since some of my web searches have m

Answer 1

For Python 3 and Django 1.9 this is what worked for me:

import multiprocessing
import django
django.setup() # Must call setup

def db_worker():
    for name, info in django.db.connections.databases.items(): # Close the DB connections
        django.db.connection.close()
    # Execute parallel code here

if __name__ == '__main__':
    multiprocessing.Process(target=db_worker)

Note that without the django.setup() I could not get this to work. I am guessing something needs to be initialized again for multiprocessing.
