I spent ages trying to find a simple example where MongoEngine was being used and a connection was being closed. Finally figured it out and posting my code.

I know this is an old question, but if anyone else is searching I figured I’d give an alternate answer.
close() does not actually remove the connection from MongoEngine’s connection list. This causes problems when trying to connect to a different database later on.
To solve this I used mongoengine.connection.disconnect (even though it’s not listed in __all__). My code looks like this:
JavaScript
x
9
1
from mongoengine import connect2
from mongoengine.connection import disconnect3
4
db = connect(alias='some_alias')5
6
{do stuff}7
8
disconnect(alias='some_alias')9
You can also leave the alias out as it will default to ‘default’ in both connect and disconnect.
