<a href="{% url "social:begin" "google" %}">Login with Google</a>

I did migrations for social_django

Answer 1

Instead of using :

<a href="{% url "social:begin" "**google**" %}">
  Login with Google
</a>

Use:

< a href="{% url 'social:begin' '**google-oauth2**' %}?next={{ request.path }}">
  Login with Google
</a>
