带导轨的多表继承 3 [英] Multi Table Inheritance with rails 3

问题描述

当涉及到 rails 3 中的多表继承时，是否有标准或最佳实践?到目前为止，我能找到的最好的文章是:

Are there standards or best practices yet when it comes to multi table inheritance in rails 3? So far the best article I could find was:

http://mediumexposure.com/multiple-table-inheritance-active-record/

但即使这样也需要一些更改(例如，将 requires 移动到初始值设定项而不是旧的/config/environment.rb)

But even that needed some changes(e.g. moving the requires to an initializer instead of the old /config/environment.rb)

有更好的资源/标准吗?

Any better resources / standards?

推荐答案

我参加的墨尔本 Ruby 小组中有一个人写了几篇关于 Rails 中表继承的博客，这些评论也很有帮助.它不是专门针对 Rails 3，但肯定有一些不错的指针.

There's a guy in the Melbourne Ruby group I attend that's written a couple of blogs on table inheritance in rails and the comments are really helpful as well. It's not specifically Rails 3 but there's definitely some decent pointers in there.
