First time Django database SQL or NoSQL?
Postgres is a great database for Django in production. sqlite is amazing to develop with. You will be doing a lot of work to try to not use a RDBMS on your first Django site.
One of the greatest strengths of Django is the smooth full-stack integration, great docs, contrib apps, app ecosystem. Choosing Mongo, you lose a lot of this. GeoDjango also assumes SQL and really loves postgres/postgis above others - and GeoDjango is really awesome.
If you want to use Mongo, I might recommend that you start with something like bottle, flask, tornado, cyclone, or other that are less about the full-stack integration and less assuming about you using a certain ORM. The Django tutorial, for instance, assumes that you are using the ORM with a SQL DB.
I've been learning Python through Udacity, Code Academy and Google University. I'm now feeling confident enough to start learning Django. My question is should I learn Django on an SQL database - either SQLite or MySQL; or should I learn Django on a NoSQL database such as Mongo?
I've read all about both but there's a lot I don't understand. Mongo sounds better/easier but at the same time it sounds better/easier for those that already know Relational Databases very well and are looking for something more agile.
