Django-Filter and query with an array

The answer given by doniyor is quite apt. But I guess request won't be available where it is used.

There is another way of doing this.You can override the get_queryset method. This can be done as follows:

class BoatList(generics.ListCreateAPIView):
    permission_classes = (IsOwnerOrReadOnly,)
    serializer_class = BoatSerializer
    filter_backends = (filters.DjangoFilterBackend,)
    filter_fields = ('id', 'home_port',)

    def get_queryset(self):
        id_list = self.request.GET.getlist("id")
        if not id_list:
            return []
        return Boat.objects.filter(id__in=id_list)

try this:

url: http://127.0.0.1:8000/api/v1/boats/boats?id=10,11

class BoatList(generics.ListCreateAPIView):
    permission_classes = (IsOwnerOrReadOnly,)
    serializer_class = BoatSerializer
    queryset = Boat.objects.filter(id__in=request.GET.getlist('id')) #<------
    filter_backends = (filters.DjangoFilterBackend,)
    filter_fields = ('id', 'home_port',)

you just creat a filter class

    class NumberInFilter(BaseInFilter, NumberFilter):
          pass


    class myFilter(FilterSet):
          id__in = NumberInFilter(field_name='id', lookup_expr='in')

          class Meta:
                model = Boat

in the viewset use the

           filter_class = myFilter

you can see this document of the django-filter: https://django-filter.readthedocs.io/en/master/ref/filters.html?highlight=BaseInFilter
