'last_login field is not updated when authenticating using Tokenauthentication in Django Rest Framework
I'm working in a project which relies in a Django User model and TokenAuthentication under DjangoRestFramework
I was requested to get last login datetime for each user and I've realized that this field is not getting updated when I call the authentication REST endpoint.
Is this a known fact? Am I missing something I must do in order to get that field updated each time the token authentication is called?
Thanks

Well, at the end I inherited from the REST Framework TokenAuthentication, pointing to it in the urls file
url(r'^api-token-auth/', back_views.TokenAuthenticationView.as_view()),
and the View handles the request and manually calls the update_last_login like this:
from django.contrib.auth.models import update_last_login
class TokenAuthenticationView(ObtainAuthToken):
"""Implementation of ObtainAuthToken with last_login update"""
def post(self, request):
result = super(TokenAuthenticationView, self).post(request)
try:
request_user, data = requests.get_parameters(request)
user = requests.get_user_by_username(data['username'])
update_last_login(None, user)
except Exception as exc:
return None
return result

@F.D.F. answer is great. Here is another way of doing it.
We send user_logged_in signals that will call update_last_login:
user_logged_in.send(sender=user.__class__, request=request, user=user)
Here is a working view (based on a custom User model that uses email as USERNAME_FIELD) :
from rest_framework import parsers, renderers
from rest_framework.authtoken.models import Token
from rest_framework.response import Response
from rest_framework.views import APIView
from django.contrib.auth.signals import user_logged_in
from emailauth.serializers import AuthTokenSerializer, UserSerializer
class ObtainAuthToken(APIView):
throttle_classes = ()
permission_classes = ()
parser_classes = (parsers.FormParser, parsers.MultiPartParser, parsers.JSONParser,)
renderer_classes = (renderers.JSONRenderer,)
serializer_class = AuthTokenSerializer
def post(self, request, *args, **kwargs):
serializer = self.serializer_class(data=request.data)
serializer.is_valid(raise_exception=True)
user = serializer.validated_data['user']
token, created = Token.objects.get_or_create(user=user)
user_logged_in.send(sender=user.__class__, request=request, user=user)
return Response({'token': token.key, 'user': UserSerializer(user).data})
obtain_auth_token = ObtainAuthToken.as_view()
You can find the full source code here : Api View with last_login updated
Hope this helps.

A cleaner way to do it:
from django.contrib.auth.models import update_last_login
from rest_framework.authtoken.models import Token
from rest_framework.authtoken.views import ObtainAuthToken
class LoginToken(ObtainAuthToken):
def post(self, request, *args, **kwargs):
result = super().post(request, *args, **kwargs)
token = Token.objects.get(key=result.data['token'])
update_last_login(None, token.user)
return result
And then setup urls.py:
url(r'^api-token-auth/', views.LoginToken.as_view()),

My answer for Django==2.0.5, django-rest-framework-social-oauth2==1.1.0
from django.contrib.auth import user_logged_in
from oauth2_provider.models import AccessToken
from rest_framework import status
from rest_framework_social_oauth2.views import TokenView
class MyTokenView(TokenView):
def post(self, request, *args, **kwargs):
response = super().post(request, *args, **kwargs)
if response.status_code == status.HTTP_200_OK:
token = AccessToken.objects.get(token=response.data['access_token'])
user = token.user
user_logged_in.send(sender=type(user), request=request, user=user)
return response
urls.py:
from django.urls import path
urlpatterns = [
path('token', MyTokenView.as_view(), name='token'),
]
Solution 5:[5]
Here is my solution using a ViewSet:
views.py:
from rest_framework.authtoken.views import ObtainAuthToken
from rest_framework.authtoken.serializers import AuthTokenSerializer
from rest_framework import viewsets
from django.contrib.auth.models import update_last_login
class LoginViewSet(viewsets.ViewSet):
"""Checks email and password and returns an auth token."""
serializer_class = AuthTokenSerializer
def create(self, request):
"""Use the ObtainAuthToken APIView to validate and create a token."""
##update last_login
try:
user = models.User.objects.get(email = request.data['username'])
update_last_login(None, user)
except:
pass
return ObtainAuthToken().post(request)
Now just add this viewset to the urls.py:
router.register('login', views.LoginViewSet, base_name="login")

impl via signals
from django.dispatch import receiver
from django.db.models.signals import post_save
from django.contrib.auth import user_logged_in
from oauth2_provider.models import AccessToken
@receiver(post_save, sender=AccessToken)
def post_save_access_token(instance, created, raw, **kwargs):
if not created or raw:
return
user_logged_in.send(sender=instance.user.__class__, user=instance.user)

This is the newest code for django 3.0.8.
:)
thx F.D.F.!
from django.contrib.auth.models import update_last_login
from rest_framework.authtoken.views import ObtainAuthToken
from django.contrib.auth import get_user_model
class TokenAuthenticationView(ObtainAuthToken):
"""Implementation of ObtainAuthToken with last_login update"""
def post(self, request):
result = super(TokenAuthenticationView, self).post(request)
currentUserModel = get_user_model()
try:
user = currentUserModel.objects.get(username=request.data['username'])
update_last_login(None, user)
except Exception as exc:
return None
return result

for anyone using knox to authenticate the user then need to edit api.py file and import user_logged_in like below
from django.contrib.auth.signals import user_logged_in
after that in LoginAPI class in the same api.py file add the below line after _, token = AuthToken.objects.create(user) like below
user_logged_in.send(sender=user.__class__, request=request, user=user)

If you're using Simple JWT for Django, you can do it pretty much easily by following this link. You just have to add
SIMPLE_JWT = {
...,
'UPDATE_LAST_LOGIN': True,
...,
}
