我曾经使用 allow_add_remove = True ，它在Django rest
2.0中可用，用于编写可嵌套的序列化程序，但在3.0中不可用，我很难实现它。

我想做这样的事情

class UserSerialzier():
    project = ProjectSerilaizer(many=True, allow_add_remove=True, read_only=False)


class ProjectSerialzier():
    ideas = IdeaSerilaizer(many=True, allow_add_remove=True, read_only=False)
    sources = SourceSerilaizer(many=True, allow_add_remove=True, read_only=False)

class IdeaSerialzier():
    pass

class SourceSerialzier():
    pass

现在我不知道如何在DRF 3.0中实现allow_add_remove行为

我很困惑，我需要重写UserSerializercreate和update方法吗

或者我需要为每个模型创建单独的IdeaListSerializer

class IdeaListSerializer(serializers.ListSerializer):
    def create(self, validated_data):
        ideas = [Idea(**item) for item in validated_data]
        return Ideas.objects.bulk_create(books)
