Thanks for the documentation. Sorry, but I'm not certain how to apply that
in my case. Since I am mapping to an existing table, how could I reference
the object attribute with an illegal name in Python? Do I combine getattr
with the documentation as below?
class Student(Model):
__table__ = Table("Students", metadata, autoload=True,
autoload_with=engine)
first_period = getattr(__table__.c, "1st_period")
Thanks,
Rob
