I have something similar to this setup
from sqlalchemy.ext.declarative import declared_attr class BaseClass(object): @declared_attr def created_by return created_by = sa.Column(sa.Integer(), sa.ForeignKey()) class RealDBObject(BaseClass): Alembic with autogenerate always likes to create drop/create on the created_by constraint for every table that uses the mixin. Is this something that can be adjusted or am I missing something? Thanks! -- You received this message because you are subscribed to the Google Groups "sqlalchemy-alembic" group.
