Question

我正在尝试保存post请求，但收到post() missing 2 required positional arguments: 'self' and 'request'错误。

查看：

class MakeLeaveRequest(generics.CreateAPIView):
  permission_classes = (IsAuthenticated,)
  serializer_class = MakeLeaveRequestSerializer
# login_url = '../../users/v1/login/'

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        if serializer.is_valid(raise_exception=True):
        # self.perform_create(serializer)
            date = serializer.save()
            print(date)
        # headers = self.get_success_headers(serializer.data)
        return Response({'ok':'ok'}, status=status.HTTP_201_CREATED)

序列化器：

class MakeLeaveRequestSerializer(serializers.ModelSerializer):
    # date_to = serializers.DateField()
    # date_from = serializers.DateField()
    # description = serializers.CharField()
    # types_of_leave = serializers.IntegerField()
    class Meta:
        model = LeaveRequest
        fields = ('date_to', 'date_from', 'description', 
                 'types_of_leave',)

    def create(self, validated_data):
        user = self.context['request'].user
        print(user)   
        # print(validated_data['date_to'])
        try:
            LeaveRequest.objects.create(user = user)
        except ObjectDoesNotExist:
            pass
        return user
