Rather by calling iteritems or to_pritimitive forces sqlalchemy to do the lazy load operations.  So if the lazyloaded data wasn\u0027t used before a missing joinedload statement wouldn\u0027t cause any errors.\n\nbut when the data is used without a joinedload we get an error like this:\n\nhttps://bugs.launchpad.net/nova/+bug/1117232","commit_id":"f7aeffef8b55be3d5195ef02cb90d2e20a503af0"}]}
