I see, your theory is pretty much accurate (sorry for my english, I hope
that phrase is correct). What I mean is that your theory is the most
addecuate for this case, thought it can't be proved. Actually, there is
another error that says something about access token been already used, but
happens very little.
My question now is: ¿can I avoid this situation and do something?
I have this in one of my models:
if session.login_facebook:
from globales import FaceBookAccount
auth.settings.login_form = FaceBookAccount(globals())
And this is te dfinition of FaceBookAccount class:
class FaceBookAccount(OAuthAccount):
AUTH_URL="https://graph.facebook.com/oauth/authorize";
TOKEN_URL="https://graph.facebook.com/oauth/access_token";
def __init__(self, g):
OAuthAccount.__init__(self, g, current.FACEBOOK_APP_ID,
current.FACEBOOK_APP_SECRET_KEY, \
self.AUTH_URL, self.TOKEN_URL, scope='email')
self.graph = None
def get_user(self):
if not self.accessToken():
return None
if not self.graph:
self.graph = GraphAPI((self.accessToken()))
user = None
try:
user = self.graph.get_object("me")
except GraphAPIError, e:
self.session.token = None
self.graph = None
if user:
return dict(first_name='%s %s' %(user['first_name'],
user['last_name']), \
username=user['id'], registration_id=user['id'],
email=user['email'])
I would like to, at least, show an error message to the user saying that
something went wrong trying to get his/her email from Facebook, and that
he/she should try again. Can't figure it out how to do it :/
