You should ask AppEngine questions on the relevant AppEngine group, not here, as this is not a Django question.
But your problem is that `.key` is a method, not an attribute, so you should call it: `employee.key()`. -- DR.

Hello,
Your question isn't related to Django, so it is not suitable for this group.
You should send questions about App Engine software to an App Engine-related group.
Having said that, the error message that you are getting is telling you that your employeekeys list does not contain keys, it contains references to the key method of each Employee instance in your query resultset.
