Not knowing the names of the primary keys shouldn't be a problem since
they're pretty easy to figure out with the object_mapper.
from sqlalchemy.orm import object_mapper
class MyMixin(object):
def get_pk(self):
om = object_mapper(self)
keys = [k.key for k in om.primary_key]
return tuple(getattr(self, k) for k in keys)
