In our case, a Psychology professor wanted something to help her students track their sleep patterns. My group pretty successfully used DJango to create a...

I'm writing a couple of Jinja2 templates that basically implement some common grid layouts. I'd like to be able to share this 'library' of templates between a Pylons app and Django app. I've hit a minor stumbling block in that Django's template context is accessible from the "top-level" of the template, whereas Pylons wraps your conte...

I've been banging on a proof-of-concept for a couple hours and the only real...
