Re: How to serialize one record with Django / REST?

Instead of using .get(), try using .filter() instead, since get_queryset() needs to return a query set and not the actual object (even though the query set will only contain a single result).

Your code for the get_queryset() override is actually better suited as an override for get_object() in the view itself.

I think you can get away without the overrides entirely if you set 'pk_url_kwarg = "pid" ' (without the single quotes) on your detail view, and you should be able to use the same serializer for both your list and detail views.

I can serialize all objects using the following.  In views:

class ProductDetail(generics.ListAPIView):

    serializer_class = ProductSerializer

    def get_queryset(self):

        return Product.objects.all()

In serializers:

class ProductSerializer(serializers.ModelSerializer):

    class Meta:

        model = Product

        fields = ('code', 'name', 'description')

When I try to restrict this to one record, I get an error:

class ProductDetail(generics.RetrieveAPIView):

    serializer_class = ProductSerializer

    def get_queryset(self):

        pid = int(self.kwargs['pid'])

        return Product.objects.get(id=pid)

Exception Type: AttributeError

Exception Value:'Product' object has no attribute 'model'

I am guessing that get_queryset is not the right thing to use in this situation.
