Solved, I can create it using .create()
and afterwards adding it to the house object with vehicles.add()
Extra steps are required due to brand being a model itself in my case.
Solution
@action(methods=['post'], detail=True, url_name='create_vehicle')
def create_vehicle(self, request,pk=None):
house = self.get_object()
brand = Brand.objects.get(id = request.data['brand'])
vehicle = Vehicle.objects.create(license_plate=request.data['license_plate'], brand=brand)
house.vehicles.add(vehicle)
return Response({'msg':'Creation success'}, status=HTTP_200_OK)
