Writing Reusable Django Apps
summary
A reusable ratings app called django polarize gets built end to end: models use a generic foreign key and the AUTH_USER_MODEL string, migrations move from South hacks to Django 1.7’s migrations, tests run via a runtests.py harness and pass locally and on Travis CI build matrix (Python 2.7/3.4, Django 1.5/1.6/1.7 RC), packaged with setup.py and uploaded to PyPI — roughly half the work is app logic, half reusable-app plumbing, and the example works.
