Rails 3 已弃用的方法和 API

有哪些资源(免费或付费)可以帮助您完成将 Ruby on Rails 2 应用程序迁移到 Rails 3 的过程?我在 RoR 网站的某处看到了一些博客文章(其中一些似乎已经过时)和一本电子书出售，但是您可以推荐什么作为从版本 2 到版本 3 的更改以及需要什么的准确和完整的解释移植到 Rails 3 环境时要更新?

What resources are out there (free or paid) that help walk you through the process of migrating a Ruby on Rails 2 application to Rails 3? I've seen some blog posts (some of which seem out of date) and an eBook for sale somewhere on the RoR website, but what can you recommend as an accurate and complete explanation of what changed from version 2 to version 3 and what needs to be updated when porting to a Rails 3 environment?

推荐答案

除了 RailsCasts 的数量，在付费方面，BDDCasts 有一个名为 升级到 Rails 3 只需 5 美元.我不能保证后者的质量(他们也有一些免费剧集)，但 Ryan 在 RailsCasts 的东西是一流的.

Aside from a number of RailsCasts, on the paid front, BDDCasts has one entitled Upgrading to Rails 3 for only $5. I can't vouch for the quality of the latter (they have some free episodes too), but Ryan's stuff at RailsCasts is top notch.

Gregg Pollack 的视频在官方网站上也提供了很好的概述.

Gregg Pollack's videos on the official site give a great overview as well.

Peepcode 也有 Rails 3 升级手册 供购买.

Peepcode also has a Rails 3 Upgrade Handbook for purchase.
