Unable to register models on django 1.9

See original GitHub issue

The example in the documentation throws the following exception in django 1.9:

  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/Users/rob/code/abett.api/env/lib/python2.7/site-packages/django/core/management/__init__.py", line 350, in execute_from_command_line

    raise AppRegistryNotReady("Apps aren't loaded yet.")

I get this exception if I try to use the <1.7 example from the docs:
