First, let me say that I'm using sqlalchemy version 0.5.8. We have a
large and complex application and changing to sa 0.6 is expensive, so
I would like, if possible, to find a solution for 0.5. I'm using
sqlalchemy since version 0.1.
I've drilled down all the way up to `mapper._save_obj()`. I examined
the `state.dict` for `qitem`.
Good case:
qitem state dict = {'campaign': Campaign 233, u'Test',
'campaign_id': 233, ...}
And for the bad case:
qitem state dict = {'campaign': Campaign 234, u'Test',
'campaign_id':

How to make Order() and Orderitems() objects during one commit()

More information is needed. Test case, psycopg2, SQLA 0.6.6, works fine:
from sqlalchemy import *
from sqlalchemy.orm import *
metadata= MetaData()
orders_table = Table('orders', metadata,
Column('id', Integer, primary_key=True, autoincrement=True),
Column('created', DateTime,

This is my first such case in 5-6 years of using the SA. Usually the
problem was with my code. This could also be the case now, but it
escapes me where I made a mistake.
Thank you for your time. I will consider this closed for now and move
on using a workaround of explicitly populating

Is it safe trust attributes.get_history(instance, attrname) from
mapper extension's before_update()?
I assume this is not reset until later?

I would like to allow the users to perform certain queries without me
