My folder structure is as follows:

/blink/
       - blink
             - __init__.py
             - settings.py
             - urls.py
             - wsgi.py
       - blinks (app folder)
             - __init__.py
             - models.py
             - views.py
             - tests.py
       - manage.py

The versions used are:

Python 2.7.5+
Django-1.5.11-py2.7
pymongo-3.0.1-py2.7
django_mongodb_engine-0.5.2-py2.7
djangotoolbox-1.6.2-py2.7

Is there anything i am missing?

Can somebody please help me on what the problem is? i am new to django and mongodb. I am not able to find the solution anywhere.

Answer

I had to downgrade the pymongo-3.0.1 to pymongo 2.7 which solved the issue. This error is because of the fact that most of the keywords has been changed or deprecated in pymongo-3.0.1.
