Help me kick start the ecommerce site using Django+mongodb by answering the questions.

[Bhaskar rao]

Hello everyone,

We are about to start this project this week and I really need someones help to start it better.

We are building an e-commerce web application using Django and mongodb and we have couple of questions to start with.

1. Can I use django.contrib.auth.user etc or or any mongo package or need to write my own auth system ? 
   
2. Can I use Django all auth, mezzanine, rest framework etc ? Do I have to write all these things on my own ? Let me know if I have to use multiple databases here (nosql + sql) so we can use mezzanine, allauth using sql database. But note that we dont have any preference. Want to know the correct way.
   
3. Please suggest python/Django packages for mongodb with django(like mongoengine or mongo-nonrel or django-mongoengine etc) that suits points 1 and 2 or our application. I dont know which actually works well. 
   

I can experiment all these that would delay the project so if anyone could answer these, I can proceed happily :)

Please let me know for any questions.
