I'm trying to integrate SimpleAuth into my app at Grajj.com, but I'm having some trouble. If you go here: grajj.com/home.html, you see I'm using the example code to try to make it work. When I click the Facebook link, though, it appears to be clearing through Facebook OK, but then dumping the session when it redirects to the next page.

I'm logging this code:
if user:
logging.info('Found existing user to log in')
# Existing users might've changed their profile data so we update our
# local model anyway. This might result in quite inefficient usage
# of the Datastore, but we do this anyway for demo purposes.
#
# In a real app you could compare _attrs with user's properties fetched
# from the datastore and update local user in case something's changed.
user.populate(**_attrs)
logging.info(self.logged_in)
logging.info(self.auth.get_user_by_session())
user.put()
self.auth.set_session(self.auth.store.user_to_dict(user))
logging.info(self.auth.store.user_to_dict(user))
else:
# check whether there's a user currently logged in
# then, create a new user if nobody's signed in, 
# otherwise add this auth_id to currently logged in user.

if self.logged_in:
logging.info('Updating currently logged in user')
u = self.current_user
u.populate(**_attrs)
# The following will also do u.put(). Though, in a real app
# you might want to check the result, which is
# (boolean, info) tuple where boolean == True indicates success
# See webapp2_extras.appengine.auth.models.User for details.
u.add_auth_id(auth_id)
else:
logging.info('Creating a brand new user')
ok, user = self.auth.store.user_model.create_user(auth_id, **_attrs)
if ok:
self.auth.set_session(self.auth.store.user_to_dict(user))

# Remember auth data during redirect, just for this demo. You wouldn't
# normally do this.
self.session.add_flash(data, 'data - from _on_signin(...)')
self.session.add_flash(auth_info, 'auth_info - from _on_signin(...)')

# Go to the profile page
logging.info('sending to profile page')
logging.info(self.auth.get_user_by_session())
logging.info(self.logged_in)
self.redirect('/profile')


And getting this in my log:

  1. 2013-11-17 21:06:55.479 Looking for a user with id facebook:5XXXXXXXX
  2. I2013-11-17 21:06:55.489 Found existing user to log in
  3. I2013-11-17 21:06:55.490 False
  4. I2013-11-17 21:06:55.490 None
  5. I2013-11-17 21:06:55.735 {'user_id': 5XXXXXXXXXXXXX}
  6. I2013-11-17 21:06:55.735 sending to profile page

  8. I2013-11-17 21:06:55.736 False

Oddly, I'm getting the same behavior on simpleauth.appspot.com. It'll let me in with Google authentication, but Facebook just keeps bouncing back to the not-logged-in page

Twas this:
self.session.add_flash(data, 'data - from _on_signin(...)')
self.session.add_flash(auth_info, 'auth_info - from _on_signin(...)')
