从Rails 2迁移到Rails 3 [英] Migrating from Rails 2 to Rails 3

问题描述

可能重复：

Rails 3已弃用的方法和API

什么资源在那里（免费或付费），帮助您走过将Ruby on Rails 2应用程序迁移到Rails 3的过程？我已经看到一些博客文章（其中一些似乎已经过时）和一本电子书在RoR网站上的某个地方销售，但是您可以推荐什么作为对从第2版到第3版的更改的准确和完整的解释，以及什么需要在移植到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 I've seen some blog posts (some of which seem out of date) and an eBook for sale somewhere on the RoR website, but what can you recommend as an accurate and complete explanation of what changed from version 2 to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 RailsCast的数量，在付费方面，BDDCasts有一个标题为升级到Rails 3 只需$ 5。我不能保证后者的质量（他们也有一些免费的剧集），但RyanCast的Ryan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有很好的概述。

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

Peepcode还有一个 Rails 3升级手册进行购买。

Peepcode also has a Rails 3 Upgrade Handbook for purchase.
