如何使用django-rest-framework创建Login视图

Question

I have a serializer and a view for my login like this.

class LoginView(generics.RetrieveAPIView):
    serializer_class= LoginSerializer
    queryset=User.objects.all()

    error_messages = {
        'invalid': "Invalid username or password",
        'disabled': "Sorry, this account is suspended",
    }

    def _error_response(self, message_key):
        data = {
            'success': False,
            'message': self.error_messages[message_key],
            'user_id': None,
        }
    def post(self,request):
        email = request.POST.get('email')
        password = request.POST.get('password')
        user = authenticate(email=email, password=password)
        if user is not None:
            if user.is_active:
                login(request, user)

                return Response(status=status.HTTP_100_OK)
            return self._error_response('disabled')
        return self._error_response('invalid')

and the serializer:

class LoginSerializer(serializers.ModelSerializer):
     class Meta:
         model=User
         fields=('email','password') 

My url:

(r'^login/$',LoginView.as_view())

When I run the code I get an error ImproperlyConfigured at /login/ Expected view LoginView to be called with a URL keyword argument named "pk". Fix your URL conf, or set the .lookup_field attribute on the view correctly.

I currently do not have redirecting in my view. what have I done wrong?

Answer 1

You are used generic.RetrieveAPIView which extends RetrieveModelMixin and GenericAPIView , as per docs it need pk or you have to set .lookup_field in your class.

RetrieveAPIView is used to get and get means retrieve data and to retrieve data it need pk .

Use another class to handle your POST
