How to solve TypeError: create() got an unexpected keyword argument in create function of my view in DRF

Question

I am faced with the problem that I can not successfully receive the kwarg's related with the id of my model Station and as a result I can not create my record through my view in the create function.

Despite the fact that I can receive the kwarg's in the get_queryset function , this is not possible in create function.

If I keep the create function only in my serializer I can create the record successfully, but instead I want to add logic and return the created record from the view to serializer and not directly create the record from serializer.

Here is my snippets:

url

path('availability/<uuid:station_id>/', StationAvailabilityList.as_view(),name = 'station_availability_list'),

view

class StationAvailabilityList(generics.ListCreateAPIView):
    serializer_class = StationAvailabilitySerializer
    permission_classes = [IsChargingStationOwnerWithStation | IsReadOnlyStations]

    def get_queryset(self):
        station_owner = self.request.user
        station_id = self.kwargs['station_id']
        station = Station.objects.get(id = station_id)
        availabilities = StationAvailability.objects.filter(station = station)
        return availabilities


    def create(self, request):
        station_id = self.kwargs['station_id']
        availability_data = request.data
        return super().create(request)

The get_queryset() works fine, i can get the id of the Station record given in the url, but in the create I get the error :

TypeError: create() got an unexpected keyword argument 'station_id'

Here is the full traceback:

serializer/ create function:

        station_data = validated_data.pop('station')
        validated_data_station_id = station_data.pop('id')

        station = Station.objects.get(id=station_id)
        station_availability = StationAvailability.objects.create(station=station,**validated_data)
        return station_availability

Can anyone help me solve this issue?

Answer 1

def create(self, request, **kwargs):
    station_id = kwargs['station_id']
    availability_data = request.data
    return super().create(request)
