Thanks again.
Changed that line and now this appears in the logs:
INFO 2011-08-19 04:02:28,358 index.py:33] Got answer, value is:
None
So it is putting something in and it is None. I am not sure why. I
must not be using .put() correctly to store the random number?
answer = Answer(ans = (random.randint(1, 100))).put()
I have tried variations of the put() such as not assigning a random
number inside this statement then referring to it, but it always comes
up as None.
