I’d like to pick up this topic once more briefly.
Suppose I get the “new”, “dirty”, and “deleted” sets as per discussion
below, and I’m especially interested in the “dirty” set: is there a way to
find out which properties of an object were modified, or only that the
object was modified?
I think that got me to where I have a working hybrid. It looks something
like this (I broke it up into multiple statements for debugging):
@isLast.expression
def isLast(cls):
dmsq = aliased(dm, name="dmsq")
q = cls.id == select([dmsq.id]).where(dmsq.department_id ==

Thanks. This occurs on create/insert so I would probably remove all primary
keys. Is there a reason why a handler would work better here? I’d prefer to

env.py is an integral part of your Alembic project space and you are
using it. Please see the tutorial at

No problem. By the way, I noticed a bug in my code, on this line:
origin_species =
session.query(Species).filter_by(name=origin_latin_name).one()
You probably want ".first()" rather than ".one()". "first()" will
either return a matching Species object or None, whereas "one()"
checks that the
