Thanks. I changed the models like this
class SiteUser(db.Model):
site_user = db.UserProperty()
total_votes = db.IntegerProperty(default=1)
liked_items = db.StringProperty()
class Item(db.Model):
user_who_liked_this_item = db.UserProperty()
title = db.StringProperty()
url = db.StringProperty()
date = db.DateTimeProperty(auto_now_add=True)
points = db.IntegerProperty(default=1)
and the VoteHandler like this (also available in pastebin
http://pastebin.com/Q1Y6vzSz):
class VoteHandler(webapp.RequestHandler):
def get(self, id):
id = int(id)
item = Item.get_by_id(id)
user = users.get_current_user()
if user:
greeting = ("%s (<a href='%s'>sign out</a>)" %
(user.nickname(),
users.create_logout_url(self.request.uri)))
#--check if user voted on this item before--#
query = SiteUser.all()
query.filter("liked_items =", (str(item.key().id())))
already_voted = query.get()
if already_voted:
self.redirect("/onevote")
else:
query = SiteUser.all()
query.filter("site_user =", users.get_current_user())
data = query.get()
data.total_votes += 1
data.liked_items = str(item.key().id())
data.site_user = users.get_current_user()
db.put(data)
item.points += 1
item.put()
if self.request.referrer == 'http://sarah-for-
president.appspot.com/newest':
self.redirect('/newest')
elif self.request.referrer == 'http://sarah-for-
president.appspot.com/hot':
self.redirect('/hot')
else:
self.redirect("/")
else:
greeting = ("<a href='%s'>Sign in with your Google account
or register</a>." %
cgi.escape(users.create_login_url(self.request.uri)))
self.response.out.write("""<div id='Small'>%s</div>""" %
greeting)
And this is the /onevote page: http://sarah-for-president.appspot.com/onevote
Not sure if this is the right way to handle this. Any suggestions?
