django-rest-framework + django-polymorphic ModelSerialization

到目前为止，我仅对GET请求进行了测试，并且可以正常工作：

class PhotoSerializer(serializers.ModelSerializer):    class meta:        model = models.Photoclass VideoSerializer(serializers.ModelSerializer):    class meta:        model = models.Videoclass GalleryItemModuleSerializer(serializers.ModelSerializer):    class meta:        model = models.GalleryItem    def to_representation(self, obj):        """        Because GalleryItem is Polymorphic        """        if isinstance(obj, models.Photo): return PhotoSerializer(obj, context=self.context).to_representation(obj)        elif isinstance(obj, models.Video):return VideoSerializer(obj, context=self.context).to_representation(obj)        return super(GalleryItemModuleSerializer, self).to_representation(obj)

对于POST和PUT请求，您可能需要做一些类似的事情，例如用to_internal_value def覆盖to_representation定义。
