I have a mixin of the following form
idx = sa.Column(sa.Integer, sa.Sequence('idx_seq', schema=???,
I would like the sequence to have the same schema as the table into which
MyMixin will be mixed. I realize I could make idx a declared_attr, and then
extract the schema from the provided cls -- and this is probably the
"right" solution -- but that would lead to the idx column going at the end
of the column list, and I really want it at the beginning. (Yes, this is
just for silly aesthetics, but *all* my tables start with idx, and I'd like
ones using MyMix to do so too.)
Is it possible to define the idx column without the sequence, and then
afterwards create the sequence and add it to the column? Or alternatively
define the sequence's schema at some later stage? Or better yet, is there
some magic setting of the sequence's schema that will have it "inherit"
from the containing table (I realize that in general sequences don't have
