Hi all,

I've got a bit of code that looks like this:

session = get_session()
session.save(obj)
session.flush()

What's the best way of telling if obj has been newly created (INSERT)
or merely updated (UPDATE)? I tried just checking for "obj.id is None"
but I can't garauntee that my primary key is called 'id'. Do I need to
introspect the primary key myself or is there a neater solution?

Cheers,

Simon
