flush should be enough, but I think you could also do:
assuming you have a relation parent
Instead of the first commit use flush. You have already committed so
you cant roll back.
so
session.begin()
try:
p=parent()
session.add(p)
session.flush()
c=child()
c.p_id=p.id
session.add(c)
session.commit()
except:
session.rollback()

flush should be enough, but I think you could also do:

c.parent.append(p)
or the other way round
p.children.append(c)
