I am trying to do a migration and am running into a problem where my
unique constraints are being delete with sqlite, but works fine with
postgres.
It seems that unique constraints are not present in the table, even before
the migration.
Ex.
engine = create_engine("sqlite:///my.db")
Session = sessionmaker(bind=engine)
s = Session()
metadata = MetaData(s.bind)
t = Table('core__users', metadata, autoload=True,
autoload_with=metadata.bind)
t.constraints shows the pk constraint, but not the unique constraints.
Is this a limitation with sqlite? Or am I doing something wrong?
Any help is appreciated.
Thanks
