Hi,
I come from another language and framework world, thus I am new to
python and gae so please excuse my ignorance.
I get this error when I call a method I added to a db.Model derived
class:
c = Greeting.count + 1
TypeError: unsupported operand type(s) for +=: 'IntegerProperty'
and 'int'
To reproduce that, I simplified my problem to modifying the HelloWorld
Greetings application. I added this to the Greetings class:
# add a count property to the model
count = db.IntegerProperty(required=True)
# add a function that uses the count
def inc_count(self):
c = Greeting.count + 1
Then, in the sample code further down, in the class Guestbook,
function post(self), I replaced the first line (instantiation of a
Greeting) with this:
greeting = Greeting(count=4)
greeting.inc_count()
The call to greeting.inc_count() causes the error pasted above. Why is
that?
