How to configure google app engine datastore (NDB) with django

[Praveen Yadav]

I am trying to use google datastore (NDB) with Django. This is the error I get when I try to put an entity.

ImproperlyConfigured at /registration/
settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

I followed To use NDB with the Django web framework and added middleware

'google.appengine.ext.ndb.django_middleware.NdbDjangoMiddleware',

But there is nothing explained about database setting So I left it blank DATABASE = {} in setting.py

What database engine should I use for google datastore.

Setting.py

Hi Praveen,

This kind of questions is better suited to www.stackoverflow.com than to our Google Groups.  This question as a valid answer and won't be subject to discussion or opinion-based point of views, so it can definitely be asked on Stack :). We try to send our customers to stack overflow with these questions, while the Google Groups are more to discuss the platform, make use-cases for feature requests or defect reports, and get a general idea of the community using our products.

Thank you for your understanding :).
