Not exactly. Django mainly came into existence as a formalization of a lot of helper functions that The Lawrence Journal-World newspaper found themselves building over and over again when they built web apps. Adrian Holovaty, Jacob Kaplan-Moss, and Simon Willison created Django separately from Rails, even if it wasn't released publicly for a while (and then got kinda stuck at 0.96 for a while after that).
It's like Newton and Leibniz with calculus or Darwin and Alfred Russel Wallace with natural selection; there were a lot of similar problems to be solved in the web dev space in the early '00's, particularly around accessing databases, structuring URLs, and handling authentication, it makes sense that a few similar approaches would show up around the same time.
If you're really interested in the history, this "Snakes and Rubies" video is worth watching: http://www.youtube.com/watch?v=cb9KDt9aXc8
(I should mention that I tend to personally prefer Python to Ruby, very much like Django, consider Adrian Holovaty a friend and we both once worked at msnbc.com at the same time.)
