For your use case, I'd drop both Rails/Django and instead go for something like Meteor.js. You'll get the benefit of a full stack framework with one language for both frontend and backend. And most of the batteries are included so you can become productive very quickly. If you choose Rails or Django, you're taking on the complexities of these frameworks + Javascript on the frontend. That's a tall order for a 3 month project when you have zero experience with all the technologies. It could take you 6 months to a year before you finish your project.
