概述
我正在尝试使用django rest框架文档中描述的高级序列化程序用法. http://django-rest-framework.org/api-guide/serializers.html#advanced-serializer-usage动态修改序列化器字段
这是我的序列化程序类：
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')
这是我的观点
class MovieFromInterpreterViewSet(viewsets.ModelViewSet):
queryset = Movie.objects.all()
serializer_class = MovieSerializer(dropfields=('moviework_work',))
我收到此错误：
TypeError: 'MovieSerializer' object is not callable
