How to change default Order from ASC to DESC in django OrderFilter

Question

I am not an expert django dev. I was trying to write a viewset which has the ordering_fields and ordering fields, but this ordering field does not have any effect. My viewset is,

class ContentViewSet(viewsets.ModelViewSet):
    queryset = Content.objects.all()
    serializer_class = ContentSerializer
    filter_backends = [OrderingFilter]
    ordering_fields = ['created_at']
    ordering = ['-created_at']

What I am looking for is, it will provide the list in descending order. However, if I add a negative sign infront of created_at in the url, it gives me what I am looking for, but I was looking for a solution where I will get the same result without using that negative sign in the url.

Thanks in advance.

You can use model Meta options. For ordering objects, you may simply add this piece of code to your model class:

class Meta:
    ordering = ["-created_at"]
