Hi, The documentation for entity-groups and transactions say that entities must all be in the same eneity group for transaction operations to work. But it does not specifically say how to put entities in the same entity group, other than some mention of setting the same parent, which it also does not say how to do.
Maybe someone could show me specifically how to do this? Let's say I have: class A(db.Model): bList = db.ListProperty(db.Key) class B(db.Model): someString = db.StringProperty() def tran(self, a, bList): bKeys = put_each_list_item_return_keys_as_list(bList) # this just calls put() on each item, returns keys a.bList = bKeys a.put() # the work bLIst = createListofBs() a = A() db.run_in_transaction(tran, a, bList) If I run this, I get this error while the items in the bList are being put: BadRequestError: Cannot operate on different entity groups in a transaction: (kind=u'B', id=65L) and (kind=u'B', id=None). How do I get everything into one entity group so this transaction will commit? Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
