django rest framework - Adding filtering changes ordering -

I have a ModelViewSet, which I want to add filtering. My normal model looks like

  class articles (models.Model): Date = = Model.Defined () language = Model.Charfild (max_long = 10) class meta: order = ['-' Date ']  

and ModelViewSet (read only):

  Category ArticleViewSet (viewsets.ReadOnlyModelViewSet): queryset = Article.objects.all () Serializer_class = Article Serializer  

The article on the API has now ordered the date to be deed as I now hope to allow the filter on the language. I have set the filter backend in settings.py in DjangoFilterBackend My Update ModelViewSet now looks like:

  Category ArticleViewSet (viewsets.ReadOnlyModelViewSet): queryset = Article.objects .all () serializer_class = ArticleSerializer filter_fields = ['language']  

This command changes the language ASC to order_by ('- date') adding The query does not change anything. Adding ordering = ('-date',) does not change anything. => How do I specify filtering and ordering (or just using default order while allowing filtering)?

Edit: By default, AutoFilterSet created in the rest of the framework comes with the current functionality: ... where order_by = true and includes the Django- The filters are given in get_ordering_field :

=> I think that is to create a FilterSet class:

  class language filter (django_filters.FilterSet ): Square Meta: Model = Text Field = ['language'] Command_b = Model () ._ Meta.ordining Classes ArticleViewSet (viewsets.ReadOnlyModelViewSet): Queryset = Article.objects.all () serializer_class = ArticleSerializer filter_cla Ss = LanguageFilter  

Is that correct? To maintain the default command, there seems to be a "lot" / verbose.
