by running the example peewee_simple.py as is, I get

$ python peewee_simple.py
Traceback (most recent call last):

maybe this is linked to https://github.com/biosustain/potion/issues/133? By changing

if column.primary_key or name in model._meta.rel: to if column.primary_key or name in model._meta.refs:, it fixes the error.
