django-allauth social account connect to existing account on login

Question

I have a custom user model and I am using django-allauth for social registration and login. I am trying to connect existing user to new social account when a user login usi

Answer 1

I managed to get this working by changing the code for adapter a little bit.

adapter.py

from allauth.socialaccount.adapter import DefaultSocialAccountAdapter

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def pre_social_login(self, request, sociallogin): 
        user = sociallogin.user
        if user.id:  
            return          
        try:
            customer = Customer.objects.get(email=user.email)  # if user exists, connect the account to the existing account and login
            sociallogin.state['process'] = 'connect'                
            perform_login(request, customer, 'none')
        except Customer.DoesNotExist:
            pass

If subclassing DefaultSocialAccountAdapter, we have to specify SOCIALACCOUNT_ADAPTER = 'myapp.my_adapter.MySocialAccountAdapter' in settings.py file
