According to this question:
The easiest way to get started with GAE/Django is with the Django non-rel bundle. However now that the latest Python/GAE SDK includes a build of Django, do we still need this?
What’s the best-practice for getting started wth Django on GAE right now?
Thanks
Update: It seems that Web app2 is the easiest choice for new projects.
This guest article suggests that
non-rel is still seemingly your best bet. Although I’d caution you that further development and/or maintenance may not happen according to their blog.
