django - Rest Framework: HyperlinkedRelatedField, return multiple attributes? -

django rest framework's hyperlinkedrelatedfield used serialize related fields this:

'tracks': [     'http://www.example.com/api/tracks/45/',     'http://www.example.com/api/tracks/46/',     'http://www.example.com/api/tracks/47/' ] 

i'm looking way return multiple attributes, like:

'tracks': [     {'id': 45, 'href': 'http://www.example.com/api/tracks/45/'},     {'id': 46, 'href': 'http://www.example.com/api/tracks/46/'},     {'id': 47, 'href': 'http://www.example.com/api/tracks/47/'} ] 

is there way achieve using drf's standard serializers?

you use nested serializer that. serializers in drf usable fields:

class trackserializer(modelserializer):     class meta:         model = track         fields = ('id', 'href')  class yourmodelserializer(modelserializer):     tracks = trackserializer(many=true) 

you have examples in official documentation, pretty close way.

if want read-write access on tracks field, have override create() , update() on yourmodelserializer. because correct behavior depends on specific application: should update fields of track? should replace associated tracks? if so, should delete associated? if tracks not exist, should create them or return error?

the documentation this thorough.
