Sorry to bug… I imagine there is no way of doing this, but would be
good to know for sure. If not, this would be really useful
functionality. For instance, I might want to populate one column based
on the contents of one of more other columns.

Hello,
I have an association object declaratively with three primary keys, but on
insert, the first (id) is not autoincremented. Please see test the code
below

Oh, thanks for the pointer. There's so much to read and learn being new to
SQLAlchemy... Sorry for bugging.

Thanks for clarifying that. The MapperExtension is what I've been
using so far for this, just wondered if there was a way to do this
with column-level defaults. Now that I think about it though, the
current way probably does make more sense, since if the values are
dependent on outside influences,
I am trying to model graph data structure where nodes can be connected
by different types of edges.
For example, we could have 2 nodes represnting persons: Alice and
Bob and we could have 3 nodes representing projects: projectA,
projectB, projectC.
Alice is working on projectA and projectC.
Bob is

I would like to encode all this in 2 database tables:
