I am new to app engine and pyton and unfortunately am not able to
accomplish a seemingly simple task - thanks for your patience.
I want to store a total miles value, which I am doing in model
TotalDistance. As each new entry is submitted I want to increment that
value. So I am getting the total value, then simply trying to add the
new entry to the existing total. I've tried this a number of different
ways, but keep getting the same error.
// This is how I have defined TotalDistance
class TotalDistance(db.Model):
count = db.IntegerProperty(required=True, default=0)
// Here's the offending code
//--- this all resides in def post(self) ---//
tdResult = TotalDistance.all()
tdCurr = tdResult.count
tempDistance = int(self.request.get('distance')) # from the form
tdMod = tdCurr+tempDistance
putTotal = TotalDistance(
total = tdMod
)
putTotal.put()
// and the error
receive the following error:
tdMod = tdCurr+tempDistance
TypeError: unsupported operand type(s) for +: 'instancemethod' and
'int'
Thanks for your help.
