Question regarding nested serializers

I'm building an API for a web application that I'm working on where I'm using a nested relationship for a create end point like the one here in the DRF framework

&#x200B;

[https://www.django-rest-framework.org/api-guide/relations/#nested-relationships](https://www.django-rest-framework.org/api-guide/relations/#nested-relationships)

&#x200B;

I want to use the serializer for updating, so I'm using a code like this:

def update(self, instance, validated_data):
tracks_data = validated_data.pop('tracks')
tracks = instance.tracks.all()
tracks = list(tracks)
instance.album_name = validated_data.get('album_name', instance.album_name)
instance.artist = validated_data.get('artist', instance.artist)
instance.save()

for track_data in tracks_data:
track = tracks.pop(0)
track.order = track_data.get('order', track.order)
track.title = track_data.get('title', track.title)
track.duration = track_data.get('duration', track.duration)
track.save()
