How to populate user profile with django-allauth provider information? - django

Question

I'm using django-allauth for my authentication system. I need that when the user sign in, the profile module get populated with the provider info (in my case facebook).
I'm trying to use the pre_social_login signal, but I just don't know how to retrieve the data from the provider auth
from django.dispatch import receiver
from allauth.socialaccount.signals import pre_social_login
#receiver(pre_social_login)
def populate_profile(sender, **kwargs):
u = UserProfile( >>FACEBOOK_DATA<< )
u.save()
Thanks!!!

Answer 1

The pre_social_login signal is sent after a user successfully
authenticates via a social provider, but before the login is actually
processed. This signal is emitted for social logins, signups and when
connecting additional social accounts to an account.
So it is sent before the signup is fully completed -- therefore this not the proper signal to use.
Instead, I recommend you use allauth.account.signals.user_signed_up, which is emitted for all users, local and social ones.
From within that handler you can inspect whatever SocialAccount is attached to the user. For example, if you want to inspect Google+ specific data, do this:
user.socialaccount_set.filter(provider='google')[0].extra_data
UPDATE: the latest development version makes this a little bit more convenient by passing along a sociallogin parameter that directly contains all related info (social account, token, ...)

Here is a Concrete example of #pennersr solution :
Assumming your profile model has these 3 fields: first_name, email, picture_url
views.py:
#receiver(user_signed_up)
def populate_profile(sociallogin, user, **kwargs):
if sociallogin.account.provider == 'facebook':
user_data = user.socialaccount_set.filter(provider='facebook')[0].extra_data
picture_url = "http://graph.facebook.com/" + sociallogin.account.uid + "/picture?type=large"
email = user_data['email']
first_name = user_data['first_name']
if sociallogin.account.provider == 'linkedin':
user_data = user.socialaccount_set.filter(provider='linkedin')[0].extra_data
picture_url = user_data['picture-urls']['picture-url']
email = user_data['email-address']
first_name = user_data['first-name']
if sociallogin.account.provider == 'twitter':
user_data = user.socialaccount_set.filter(provider='twitter')[0].extra_data
picture_url = user_data['profile_image_url']
picture_url = picture_url.rsplit("_", 1)[0] + "." + picture_url.rsplit(".", 1)[1]
email = user_data['email']
first_name = user_data['name'].split()[0]
user.profile.avatar_url = picture_url
user.profile.email_address = email
user.profile.first_name = first_name
user.profile.save()
If you are confused about those picture_url variable in each provider. Then take a look at the docs:
facebook:
picture_url = "http://graph.facebook.com/" + sociallogin.account.uid + "/picture?type=large" Docs
linkedin:
picture_url = user_data['picture-urls']['picture-url'] Docs
twitter:
picture_url = picture_url.rsplit("_", 1)[0] + "." + picture_url.rsplit(".", 1)[1] Docs And for the rsplit() take a look here
Hope that helps. :)

Answer 3

I am doing in this way and taking picture (field) url and google provider(field) as an example.
socialaccount_obj = SocialAccount.objects.filter(provider='google', user_id=self.user.id)
picture = "not available"
if len(socialaccount_obj):
picture = socialaccount_obj[0].extra_data['picture']
make sure to import : from allauth.socialaccount.models import SocialAccount

Answer 4

There is an easier way to do this.
Just add the following to your settings.py. For example, Linked in...
SOCIALACCOUNT_PROVIDERS = {
'linkedin': {
'SCOPE': [
'r_basicprofile',
'r_emailaddress'
],
'PROFILE_FIELDS': [
'id',
'first-name',
'last-name',
'email-address',
'picture-url',
'public-profile-url',
]
}
The fields are automatically pulled across.
