Does anybody else find transactions very restricting? How do I solve this problem? Here is my data model...
Team(db.Model): name = db.StringProperty() Game(db.Model): team1 = db.ReferenceProperty(Team, collection_name='game1_set') team2 = db.ReferenceProperty(Team, collection_name='game2_set') ... if I delete a team, I want to delete all the games associated with it as well so I need to put the delete operation in a transaction. But how would I setup the entity group? setup 1) Team as parent of Game - but there can be only 1 parent and team1 and team2 should both be parents - DOESN'T WORK setup 2) Game as parent of Team - then that would mean each team can only play 1 game? DOESN'T WORK setup 3) create a 3rd entity and let that be the parent of both Team and Game - but then all teams and games would be in the same entity group - is this my only option? Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
