RESULTS = QUERY.fetch(10) RESULTS.sort(key=lambda x: x.mDATE.toordinal() * x.mCOUNT)
What is a "list of model instances? You can start by learning some basic python. Read the tutorial on the python.org website, or in the help file (on windows platform) 2010/11/10 Zeynel <azeyn...@gmail.com>: > Can someone help me understand how to access the results of a query? > > This is my model: > > class Rep(db.Model): > mAUTHOR = db.UserProperty(auto_current_user=True) > mUNIQUE = db.StringProperty() > mCOUNT = db.IntegerProperty() > mDATE = db.DateTimeProperty(auto_now=True) > mDATE0 = db.DateTimeProperty(auto_now_add=True) > mWEIGHT = db.IntegerProperty() > > The app has a textarea form and user submits repetitions. mCOUNT is > the number of repetitions.
