I have no idea what is wrong. I've been trying to get mongodb to work with django and I have been having a lot of issues. My settings.py:
DATABASES = {
    'default': {
        'ENGINE': 'django_mongodb_engine',
        'NAME': 'qmcdb_mongodb',
        'PORT': 27017,
        'HOST': 'localhost'
    }
}

I hope I have posted enough background information. I would really appreciate any help.

A:

Try use Mongo database in version 3.2, There is some problem with mongoengine and Mongo Server 3.4
