Django Rest-Framework nested serializer order

Question

Is there a way to order a nested serializer _set, for example order by pk or time-stamp.

So basically order song_set

Answer 1

In your ViewSet, you can specify a queryset with a custom Prefetch object that you can filter and order as you like. Prefetching causes just one additional database query (instead of one per parent object when using SerializerMethodField), giving vastly improved performance.

from rest_framework import viewsets
from django.db.models import Prefetch

class AlbumViewSet(viewsets.ModelViewSet):
    queryset = Album.objects.prefetch_related(Prefetch('song_set',
        queryset=Song.objects.order_by('-timestamp')))
