Hey @antwal, thanks for the report.

Can you share the model you are using, so I can try to reproduce the environment and (hopefully) fix the bug?

Cheers

Hi,

this is example;

abstract.py

class Base(db.Model):
    __abstract__  = True

    id = db.Column(db.Integer, primary_key=True)

users.py

class Users(Base):
    __tablename__ = 'users'

    client = db.Column(db.String(12))
    address = db.Column(db.String(15))

    def __init__(self, client=None, address=None):
        self.client = client
        self.address = address

I have used your example to create backups; but not working; I have tryed with standard example working.

Thanks.

Thanks. I'll try to take a look during the weekend.
(But surely anyone is free to send a PR)

Hey @antwal,

I couldn't fix it, but probably the problem comes form the fact that:

__abstract__ causes declarative to skip the production of a table or mapper for the class entirely [source]

AlchemyDumps backs up mapped class only. I'm not sure how to get non-mapped class. Anyone? I really can't focus on that in the short term.
