I need to get the corresponding user object. How would I go about doing this?

Answer 1

Suppose you wanna get userid and username when obtain auth token in Django Rest Framework

More info can get from https://www.django-rest-framework.org/api-guide/authentication/#by-exposing-an-api-endpoint

# in views.py
from rest_framework.auth.models import Token
from rest_framework.auth.views import ObtainToken
from rest_framework.response import Response

class MyObtainToken(ObtainToken):
   """Return User Info along with token"""
   def post(self, request, *arg, **kwarg)
       serializer = self.serializer_class(request.data, context={'request':request})
       serializer.is_valid(raise_exception=True)
       user = serializer.valided_data['user']
       token, _ = Token.objects.get_or_create(user)
       return Response(
            {
                 'token': token.key,
                 'username': user.username,
                 'userid': user.pk
            })
# in urls.py
urlpatterns += [path(r'api/obtain_auth_token', MyObtainToken.as_view()]
