Hello I have an ordering via modeviewset class PostViewSet(viewsets.ReadOnlyModelViewSet): queryset = Post.objects.all() serializer_class = PostSerializer pagination_class = LimitOffsetPagination filter_backends = [filters.OrderingFilter] ordering_fields = ['title'] ordering = ['title'] When I try http://localhost:8000/posts/?ordering=something_else I don't get any exception or mistake(404). How can I validate this valued(ordering) and raise custom response if attribute doesnt exist?

Rest all other instances can be viewed...no error

you can create your own custom filter backends for that. btw are you sure OrderingFilter accept ordering as param and not fields? coz iirc it should be fields but am not sure

Defining filterset_class in view (and putting required logic in it) is more correct in this case

filterset_class??

https://django-filter.readthedocs.io/en/master/guide/rest_framework.html#adding-a-filterset-with-filterset-class

i dont think so, since what he want to do is raising 404 when passed field invalid

Using filter_backeds property in views is like defining serializer fpr view with serializer_fields -- thanks god that is not possible

Defining filterset_class in view (and putting required logic in it) is more correct in this case

actually what am trying to suggest is before the code reach https://github.com/carltongibson/django-filter/blob/master/django_filters/filters.py#L711 he should raise 404, so he should make his own custom filter_backends. that also where the ordering fields from get param requests parsed

Subclass this Filter and just add required check

and about this, personally am not recommending this method coz he will need to write that logic for each view which implement this

Not so many code -- and this is like always write get_queryset instead of just queryset=

maybe, try paste it in dpaste.de ?

What's that... I don't have any idea about dpaste

great, then you'll have a new tool in your dev tool list, just try open it

But how to use it...

pk should be integer, while you pass (empty) string

In html code ?

maybe, you should check your full traceback for that
