If I passed a list of key ids as an argument in a transaction, would the change associated with the first key in the list happen first? And if not, how do I specify the order that I want the changes to happen in?
As a concrete example, consider this code below from Google Docshttp://code.google.com/appengine/docs/python/datastore/transactions.html---would changes to the first item in acc.key() happen first? class Accumulator(db.Model): counter = db.IntegerProperty() Docshttp://code.google.com/appengine/docs/python/datastore/transactions.html: def increment_counter(key, amount): obj = db.get(key) obj.counter += amount obj.put() q = db.GqlQuery("SELECT * FROM Accumulator") acc = q.get() db.run_in_transaction(increment_counter, acc.key(), 5) -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
