yes, you are right, my bad, my old code have a race condition because of assigned with max id *e.g.* *have a race condition (don't use it if transaction is high)* id_max = db.order.id.max() maxID = db(db.order).select(id_max).first()[id_max] order_id = int(maxID) + 1 if maxID else 1 db.item.order_id.default = order_id
*doesn't have a race condition (best practice)* order_id_1 = db.order.insert(name = 'order1') db.item.insert(name = 'item1', order_id = order_id_1) best regards, stifan -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
