Thanks for the heads up on logging.
I tried the logging but don't know if I did it right. For the first
logging part in the code, I put:
logging.info('Wrote answer, key is: %s', str(answer.key()))
and it gave me this in the browser:
AttributeError: 'Key' object has no attribute 'key'
I tried replacing key with ans but that gave the same error type.
When I just put:
logging.info('Wrote answer, key is: %s', str(answer))
the log file comes with this:
Wrote answer, key is agxkZXZ-bnVtZ3Vlc3NyDAsSBkFuc3dlchhUDA
Am I doing something wrong or does this info mean anything? I honestly
don't know what to make of it or what to change to get the random
number in/out.. I feel like I am following what the docs say though.
