You're posting this problem to the wrong place. There are too many enthusiasts in the Ruby/Rails and Django camps for you to get a reasonably straight answer. Instead of asking here, I suggest that you pick a subset of your project that can be put together as one program and try to write it in both Ruby on Rails and Django. When you've seen what's required for either, you'll then be able to go back and build the rest of the system in your framework of choice.
