在我手动执行此操作之前，是否有一个很好的宝石/简单的方法可以在 Rails 3 中包含评级、收藏夹等内容？
我想手动完成此操作并不难，但我很好奇是否有简单的方法来包含“可评级”或“可收藏”等概念。我猜这真的很容易手工完成，但是有针对此类事情的标签库，它们还提供范围，标签云和具有正确索引策略的正确迁移......所以我想也许可能有类似的事情是包罗万象的，因为这些东西基本上都是相同的想法。
I guess it's not so hard to do this by hand, but I was curious if there was easy ways to include concepts like "Ratable" or "Favouritable" and so on. It's really easy to do by hand I guess, but there are tag libraries for this sort of thing that also provide scopes, tag clouds and the correct migrations with the right indexing strategies... so I thought maybe there might be a similar thing that is all encompassing since these things are basically the same idea.
