Trying to understand this error I get when I run a doctest?

I'm trying to run doctests using python3 -m doctest worklog-db.py as Kenneth shows us in the testing course, but I get this error:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/runpy.py", line 184, in _run_module_as_main

  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/peewee.py", line 318, in __getattr__
    return self[attr]
KeyError: '__wrapped__'

Anyone have any idea what this is about?

You sent me your code and I gave it a look. You're not doing anything wrong, at least not regarding your doctests. The problem comes from Peewee. I filed an issue here about it.

To fix it in the meantime, though, use import peewee (instead of from peewee import *) and then prepend peewee. to all of your Peewee-provided objects. For instance, peewee.Model instead of just Model.

Okay this seems to be working! Thanks Kenneth!
