Ahhhh, deferred (new to me), thanks!
in sqlalchemy/test/orm/sharding/test_shard.py:
mapper(WeatherLocation, weather_locations, properties={
'reports':relation(Report, backref='location'),
'city': deferred(weather_locations.c.city),
})
When I comment out the deferred property, it behaves as I would
suspect (one query_chooser call).
Ok, that answers Question #1.
Question #2 similar, but w/ session.add(). I'll send a new email for
Question #2.
Thanks,
--diana
