Facebook Doesn't Return Email Python Social Auth

here's my pipeline in settings.py:

SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'accounts.pipeline.create_user',
    'accounts.pipeline.update_user_social_data',
    # 'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details',
)

along with this line:

SOCIAL_AUTH_FACEBOOK_SCOPE = ['email']

I tried this as well:

FACEBOOK_EXTENDED_PERMISSIONS = ['email']

and in my pipeline.py:

def create_user(strategy, details, user=None, *args, **kwargs):
    if user:
        return {
            'is_new': False
        }

    fields = dict((name, kwargs.get(name) or details.get(name))
                  for name in strategy.setting('USER_FIELDS',
                                               USER_FIELDS))

    if not fields:
        return

    if strategy.session_get('signup') == 'UserType1':
        user1 = UserType1.objects.create_user(username=fields.get('username'))
        user1.user_type = User.USERTYPE1
        user1.save()

        return {
            'is_new': True,
            'user': user1
        }

    elif strategy.session_get('signup') == 'UserType2':
        user2 = UserType2.objects.create_user(username=fields.get('username'))
        user2.user_type = User.USERTYPE2
        user2.save()

        return {
            'is_new': True,
            'user': user2
        }


def update_user_social_data(strategy, *args, **kwargs):
    if not kwargs['is_new']:
        return

    full_name = ''
    backend = kwargs['backend']

    user = kwargs['user']

    full_name = kwargs['response'].get('name')
    user.full_name = full_name

    email = kwargs['response'].get('email')
    user.email = email

    user.save()

However, kwargs['response'].get('name') returns user's full name correctly, but kwargs['response'].get('email') is always none. When I do print kwargs['response'], it only shows uid and the name of the user as well, so Facebook doesn't return user's email. How to overcome this? Thanks!

Apparently you need to make another request like following (again in social pipeline):

def update_user_social_data(strategy, *args, **kwargs):
    if not kwargs['is_new']:
        return

    user = kwargs['user']

    fbuid = kwargs['response']['id']
    access_token = kwargs['response']['access_token']

    url = u'https://graph.facebook.com/{0}/' \
          u'?fields=email' \
          u'&access_token={1}'.format(
        fbuid,
        access_token,
    )

    request = urllib2.Request(url)
    email = json.loads(urllib2.urlopen(request).read()).get('email')

    user.email = email
    user.save()
