django-taggit怎么列出某篇文章的tag

django-taggit官方的使用说明
>>> apple = Food.objects.create(name="apple")
>>> apple.tags.add("red", "green", "delicious")
>>> apple.tags.all()
[<Tag: red>, <Tag: green>, <Tag: delicious>]
>>> apple.tags.remove("green")
>>> apple.tags.all()
[<Tag: red>, <Tag: delicious>]
>>> Food.objects.filter(tags__name__in=["red"])
[<Food: apple>, <Food: cherry>]
----------------------------------
到了这一步，怎么取出tag，列出apple，cherry这些标签
