I have been using Turbogears 1 for prototyping small sites for the last couple of years and it is getting a little long in the tooth. Any suggestions on making the call between upgrading to Turbogears 2 or switching to something like Django? I'm torn between the familiarity of the TG community who are pretty responsive and do pretty good documentation vs the far larger community using Django. I am quite tempted by the built-in CMS features and the Google AppEngine support.
I have experience with both Django and TG1.1.
IMO, TurboGears strong point is it's ORM: SQLAlchemy. I prefer TurboGears when the database side of things is non-trivial.
Django's ORM is just not that flexible and powerful.
That being said, I prefer Django. If the database schema is a good fit with Django's ORM I would go with Django.
In my experience, it is simply less hassle to use Django compared with TurboGears.
TG2 is built on top of Pylons which has a fairly large community as well. TG got faster compared to TG1 and it includes a per-method (not just web pages) caching engine. I think it's more AJAX-friendly than Django by the way pages can be easly published in HTML or JSON .
