[sqlalchemy] Re: save_or_update() with a unique but not primary key
Perhaps he's looking for an upsert function? That's sometimes handy, and to be truly useful would have to be able to use any given key on the table. I hacked up an upsert for SQLObject once, but it was so ugly I never contributed it. It did make the poor man's replication system that I was working on simpler, though.
