Answer 1

Just follow the instructions in the trace back. you need django.db.backends.django_mongodb_engine as the engine. Not just django_mongodb_engine.
If you havent already you will probably need a couple dependencies for the engine to work. im on mobile and dont know what they are called at the moment for mongodb
