Hi all,
I got this error when I tried to run a query in a transaction, "Only
ancestor queries are allowed inside transactions".
I have a class, C1, whose entities have no ancestors. I want to query a
particular entity from it, modify, and put it back, for example,
item = C1.gql("WHERE p1 = :a AND p2 = :b ORDER BY p2", a = None, b =
23).fetch(1)
item.p1 = sth
item.put()
The above code should run in a transaction. What should I do?
Thanks in advance.
Will
