Hello,
I am reading this sample app called overheard
http://code.google.com/appengine/articles/overheard.html to add
ranking functionality to my app.
His models.set_vote() function has a line
vote = Vote.get_by_key_name(key_names = user.email(), parent = quote)
and his Vote model is
class Vote(db.Model):
"""Storage for a single vote by a single user on a single quote.
Index
key_name: The email address of the user that voted.
parent: The quote this is a vote for.
Properties
vote: The value of 1 for like, -1 for dislike.
"""
vote = db.IntegerProperty(default=0)
Where does he get the key_names? They are not included in the Vote?
models.py is here:
