Thanks much, Scott. They both seem a bit hacky, but it gives me something to work with anyway.
I recognize the motivation for forcing bi-directional relationships in Django was done to keep things DRY[1], but does anyone know if there's been any discussion about maybe relaxing this constraint? Seems a little restrictive, and I don't think most other web frameworks go this route for that very reason...
