I have got up to speed with Ruby on Rails fairly quickly via this free online course which is currently being offered by UC Berkeley - Software as a Service - Engineering Long Lasting Software with instruction by Armando Fox and David Patterson. I can't speak highly enough of this course... it really was a privilege to learn Rails from these guys. And there is an active community on the course forums if you run into difficulty along the way. The first offering of the online course has now finished (as of 25 March, 2012) - the next time it will be run will be sometime in September of 2012.

It assumes you are a fairly competent developer and gets you started on ruby in the second week, then Rails runs from the third week up to the end of the course (five weeks). Your assignments are marked by an auto-grader. You get provided with a pre-built Ubuntu VM image with everything you need for development pre-installed on it (e.g. Ruby, Rails, Rake, Gems, RSPec, Cucumber, etc). All you have to do is start up the VM inside the (free) VirtualBox software which runs on MacOSX, Windows and Linux.

这门课有一本推荐教材。在这里……但是你可以在网上看讲座和视频。

http://www.teachmetocode.com是学习Ruby和Ruby on Rails的绝佳来源。这里有一些介绍Rails基础知识的屏幕视频，还有一个由6部分组成的系列，介绍如何使用Ruby on Rails创建Twitter克隆版。

我以前在windows上用Java和c#编程。

我赞同这些来源:

IDE:尝试Apatana RadRails 3预览:http://www.radrails.org/3。它是最接近Visual Studio的东西。我偶尔会使用它，但仍然喜欢Textmate的轻盈感。

OS: Mac OS从Ruby社区得到了最多的爱。其他的都被当作私生子对待。

书:

实用程序员指南(十字镐书) 使用Rails进行敏捷Web开发

视频:

Peepcode (pay)是一种快速掌握概念的好方法 Railscasts(免费)是一个很好的方法，每周获取新的宝石和概念增量 Railscasts(专业版)也是一种以相当低的价格获取概念的好方法。

学习任何东西(包括Ruby on Rails)的最快方法是结对编程。

找一个懂Rails的人，选择一个示例应用程序，坐下来，解决bug，添加功能。

知识共享是不可思议的。
