Turns out inside the serializer I need to use:

self.context.get("request").parser_context["kwargs"]["album_id"]

Instead of passing album_id in context, you can pass album_id via serializer.save() and DRF will automatically create Song object with album_id field.

You need to make some changes to your code.

In your views, you don’t need to pass context to the serializer. You should instead pass album_id in serializer.save().

@detail_route(methods=['post', 'get'], serializer_class=SongSerialiser)
def get_so(self, request, album_id=None):
    serializer = self.get_serializer(data=request.data)
    if serializer.is_valid():
        serializer.save(album_id=album_id) # pass album_id here
        return Response(serializer.data, status=status.HTTP_200_OK)
    else:
        return Response({"detail": serializer.errors,
                         "status_code": status.HTTP_400_BAD_REQUEST})

Secondly, you can convert SongSerialiser to ModelSerializer having only the field song_name without adding the create() method. 

class SongSerialiser(serializers.ModelSerializer): # use modelserializer

    class Meta:
        model = Song
        fields = ['song_name'] # only define song_name field

When serializer.save() is called, DRF will create Song object with song_name from request.data and album_id from extra kwarg we passed in .save().
