Allow user to register using django-all-auth even if the social account exists and then connect the two automatically - django-allauth

Question

So, I have been able to connect social accounts (fb or google) to be connected to the local email account if already exists.
However, I also want the reverse functionality, i.e. I would like to allow user to sign up even if the (google or FB) social account exists. Currently it says:
{ A user is already registered with this email address }
I am using django-all-auth and django-rest-auth with Django 2.1

Yes, you can do that. You should be able to modify the password reset endpoint provided by django-rest-auth to set a password and then be able to login:
from django.contrib.auth import get_user_model
from django.contrib.auth.forms import PasswordResetForm as DjangoPasswordResetForm
from rest_auth.serializers import (
PasswordResetSerializer as RestAuthPasswordResetSerializer
)
from rest_auth.views import PasswordResetView as RestAuthPasswordResetView
UserModel = get_user_model()
class PasswordResetForm(DjangoPasswordResetForm):
def get_users(self, email):
"""
Given an email, return matching user(s) who should receive a reset.
"""
active_users = UserModel._default_manager.filter(**{
'%s__iexact' % UserModel.get_email_field_name(): email,
'is_active': True,
})
return iter(active_users)
# or (u for u in active_users if not u.has_usable_password())
class PasswordResetSerializer(RestAuthPasswordResetSerializer):
password_reset_form_class = PasswordResetForm
class PasswordResetView(RestAuthPasswordResetView):
serializer_class = PasswordResetSerializer
You can add this view to your urls.py as general endpoint to reset passwords (remember to place it in front of the rest_auths' URLs) or as an additional endpoint to set passwords (see the commented line). Then you can add a note to your signup page that links to your page that serves your new endpoint.
As an alternative, you could also add a field to your user settings page where users can set a password.
You could also send an e-mail with a link via send_confirmation to set a password when a user tries to sign up and the e-mail exists already (or only in case this user has a social account). If you like I could add an example here how to do that.
