You're totally right of course. I was to focused on the idea of creating queries based on models and somehow getting models back. Somehow I got caught up in this completely wrong way of thinking about the problem.

I greatly enjoyed watching the talk. You make it obvious what to take away from the talk and your explanations are easy to follow along with. In the first part of the talk, you really took advantage of Python's dynamicity to describe something very static. I hope that's something that will stay in my mind and change how I write code in the future.
