web2py book standalone facebook login doesn't work.

[guruyaya]

It doesn't even make sense, as the facebook object init function needs a variable called g, that it doesn't use use in the inital call. I've filling in the g with None, I can get the login to direct me to facebook and back, but it's not registering my user (I see no change in the auth_user table). Any chance someone can make a quick fix for this one, because I'm kinda lost at this point

The g argument is due to backward compatibility to when the globals() needed to be passed explicitly in web2py since there was no gluon.current. The following is a shorter version of what I use in production.

        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:

            session.token = None

            self.graph = None

        if user:

            if not user.has_key('username'):

                username = user['id']

            else:

                username = user['username']

                

            if not user.has_key('email'):

                email = '%s.fakemail' %(user['id'])

            else:

                email = user['email']    

            return dict(first_name = user['first_name'],

                        last_name = user['last_name'],

                        username = username,

                        email = '%s.%s' %(email) )

This one worked. after I've replaced 

 email = '%s.%s' %(email) )

with 

 email = '%s' %(email) )

(I have no idea why the extra %s is there).

Thanks

my bad I did a cleanup and forgot the %s ;-)
