I am using Celery and MongoEngine as part of my Django App with.
I am getting this warning, when a celery @shared_task accesses the mongodb database via mongoengine model classes:
UserWarning: MongoClient opened before fork. Create MongoClient with
connect=False,or create client after forking. See PyMongo's
documentation for details:
http://api.mongodb.org/python/current/faq.html#using-pymongo-with-multiprocessing
It clearly has something to do with multiprocessing and pyMongo that is that mongoengine is based on.
My question is:
What is the best strategy to avoid this issue with mongoengine?
Please note that i am connecting to the mongodb with mongoengine in the settings.py:
mongoengine.connect('my_mongo_database_name', alias='default')
