在Django Rest Framework中使用Tokenauthentication进行身份验证时，不会更新last_login字段

Question

我正在一个项目中工作，该项目依赖于Django用户模型和DjangoRestFramework下的TokenAuthentication

我被要求为每个用户获取最后一次登录日期时间，并且我已经意识到当我调用身份验证REST端点时，该字段没有得到更新。

这是一个已知的事实吗？为了在每次调用令牌认证时更新该字段，我是否遗漏了必须执行的操作？

谢谢

Answer 1

好吧，最后我从REST Framework TokenAuthentication继承，在urls文件中指向它

url(r'^api-token-auth/', back_views.TokenAuthenticationView.as_view()),

并且View处理请求并手动调用update_last_login，如下所示：

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。答案很棒。这是另一种方法。

我们发送将调用user_logged_in的update_last_login信号：

user_logged_in.send(sender=user.__class__, request=request, user=user)

这是一个工作视图（基于使用电子邮件作为USERNAME_FIELD的自定义用户模型）：

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()

你可以在这里找到完整的源代码：Api View with last_login updated

希望这可以帮助。

更简洁的方法：

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

然后设置urls.py：

url(r'^api-token-auth/', views.LoginToken.as_view()),

我对Django==2.0.5，django-rest-framework-social-oauth2==1.1.0的回答

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.朋友:

from django.urls import path

urlpatterns = [
    path('token', MyTokenView.as_view(), name='token'),
]

Answer 5

这是我使用ViewSet的解决方案：

views.朋友:

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)

现在只需将此视图集添加到urls.py：

router.register('login', views.LoginViewSet, base_name="login")
