MongoEngine: Close connection


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.


Solution

  • 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:

    from mongoengine import connect
    from mongoengine.connection import disconnect
    
    db = connect(alias='some_alias')
    
    {do stuff}
    
    disconnect(alias='some_alias')
    

    You can also leave the alias out as it will default to 'default' in both connect and disconnect.
