You defined your trackSerializer in wrong way.

Track model doesn’t have track_parent or track_child attributes. They belong to Album model. Remember that related_name is an attribute to defined how your pointed model, in this case Album may retrieve their backwards model instances aka Track instances. related_name does not rename the attribute as you think it does.

Also, track_parent represents Track instances, you can’t serializer a Track instance using albumSerializer

class trackSerializer(serializers.ModelSerializer):

    class Meta:
        model = Track
        fields = ('pk_track',)


class albumSerializer(serializers.ModelSerializer):
    album_title = masterSerializer()
    album_description = masterSerializer()
    track_parent = trackSerializer(many=True, read_only=True)
    track_child = trackSerializer(many=True, read_only=True)

    class Meta:
        model = Album
        fields = ('album_title', 'album_description','track_parent', 'track_child')
