Let me tell you the truth, though this will not be popular: Django is not a good framework. It's clumsy, inflexible and restrictive. The community is pretty much dead. If you want to work in ruby, go for ror. If you want to work in python, go for a micro framework like Bottle. I made the mistake of investing a lot of my time in Django. It was not worth it in the end. All my Django projects ended up being a big mess,…
I don't think that you can compare ANY Python framework (or any framework in any language) with Ruby on Rails. If you write Ruby, use RoR. If you write Python, don't use RoR.
Also, for anyone recommending something like Tornado, please stop. It's NOT THE SAME THING and completely off topic. If you want something micro for a small concise project use Flask.
