I'm seeking a nice complete open source django application to study and learn best practices from, or even use as a template. The tutorials only go so far, and django is super flexible which can lead one to paining themselves into a corner.

Ideally such a template / example would:

• Ignore django admin, and implement full CRUD outside the admin.
• Be built like a large application in terms of best practices and patterns.
• Have a unit test
• Use at least one package (e.g. twitter integration or threaded comments)
• Implement some AJAX or Comet
