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?

I'm building and API on top of Flask using marshmallow and mongoengine. When I make a call and an ID is supposed to be serialized I receive the following error: TypeError: ObjectId('54c117322053049ba3ef31f3') is not JSON serializable I saw some ways with other libraries to override the way the ObjectId is treated. I haven't figured it out with Marshmallow yet, does anyone know how to do that? My model is: class Process(db.Document): name = db.StringField(max_length=255, required=True, unique=True) created_at = db.DateTimeField(default=datetime.datetime.now, required=True) My serializer: class

I need get documents from db by oid, like: Docs.objects(_id='4f4381f4e779897a2c000009') But how to do it, if _id requires ObjectId object and even I try to set ObjectId from pymongo it doesn't work. Docs.objects(_id=pymongo.objectid.ObjectId('4f4381f4e779897a2c000009')) return empty list How about just using the raw string: Docs.objects.get(id='4f4381f4e779897a2c000009') That is probably the easiest way ... right ? This should work: Docs.objects(pk='4f4381f4e779897a2c000009') Came to this question because I had a lot of trouble with this myself. It seems like PyMongo changed this and objectid

I'm using the bottle framework together with mongoengine. I have an orders model : class OrderDetail(Option): orderDetailsQty = FloatField() def to_dict(self): return mongo_to_dict_helper(self) class Order(Document): userName = StringField(required=True) orderDate = DateTimeField() orderStatus = ListField(EmbeddedDocumentField(Status)) orderDetails = ListField(EmbeddedDocumentField(OrderDetail)) orderComments = ListField(EmbeddedDocumentField(Comment)) isActive = BooleanField() def to_dict(self): orderObj = mongo_to_dict_helper(self) orderDetailList = [] for orderDetail in orderObj[

I want to be able to do conditional connect() based on either I started django in testing mode or not. in my settings.py I use mongoengine connect() method to connect to my database but the problem is that I don't want to do that if I ran manage.py test Is there any way I can check if settings.py is being imported from tests or not, some flag maybe. something like if not IN_TESTS: connect() I'm solving this with a custom test runner. Here is an example I based my solution off of: https://github.com/xintron/django-mongorunner/blob/master/mongorunner/testrunner.py This has the advantage of
