Dynamiquement modifier sérialiseur champs dans Django Repos Cadre

Je suis en train d'utiliser les Avancées sérialiseur utilisation décrites dans le django de repos cadre de la documentation. http://django-rest-framework.org/api-guide/serializers.html#advanced-serializer-usage dynamiquement modifier sérialiseur champ

Voici mon sérialiseur classe:

class MovieSerializer(serializers.ModelSerializer):
    moviework_work = MovieWorkSerializer(many=True) 

    def __init__(self, *args, **kwargs):
        # Don't pass the 'fields' arg up to the superclass
        dropfields = kwargs.pop('dropfields', None)

        # Instantiate the superclass normally
        super(MovieSerializer, self).__init__(*args, **kwargs)

        if dropfields:
            # Drop fields specified in the `fields` argument.
            banished = set(dropfields)
            for field_name in banished:
                self.fields.pop(field_name)
    class Meta:
        model = Movie
        fields = ('field1','field2','moviework_work')

Voici mon viewset

class MovieFromInterpreterViewSet(viewsets.ModelViewSet):
    queryset = Movie.objects.all()
    serializer_class = MovieSerializer(dropfields=('moviework_work',))

J'obtiens cette erreur:

TypeError: 'MovieSerializer' object is not callable
