从 Rails 3 升级到 Rails 3.1 [英] Upgrading from Rails 3 to Rails 3.1

问题描述

如何从 Rails 3 升级到 Rails 3.1 测试版?

How do you upgrade from Rails 3 to Rails 3.1 beta?

推荐答案

这是更新现有 Rails 3.0.8 项目时对我有用的方法.您的里程可能会有所不同...

This is what worked for me when updating an existing rails 3.0.8 project. Your mileage may vary...

更新我的 Gemfile 中指定的 rails 版本以使用最新的候选版本:

Update the rails version specified in my Gemfile to use the latest release candidate:

gem 'rails', '3.1.0.rc4’

更新捆绑包:

bundle update

然后使用 rake 命令更新项目:

Then update the project with the rake command:

rake rails:update

虽然发生了变化冲突，但在挑选樱桃后，我运行了所有测试，结果都通过了(是的！).我重新启动了服务器，到目前为止一切都很好.

After cherry picking though the change conflicts I ran all my tests and they passed (yay!). I restarted the server and everything seems good so far.

但是，这还没有使用新的资产管道.我的意思是 javascript 和 css(或 sass)文件仍在以管道前的方式处理.据我了解，这是一个完全可行的选择.但当然，我想要新的优点，所以我相信接下来的步骤是包含和额外的 gems(例如 coffeescript、sass、uglifier 等)，然后将旧文件迁移到 app/assets 目录.

However, this is not using the new asset pipeline yet. By that I mean the javascript and css (or sass) files are still being handled in the pre-pipeline manner. As I understand it, this is a perfectly viable option. But of course, I want the new goodness, so I believe the next steps are to include and additional gems (e.g. coffeescript, sass, uglifier, etc) and then to migrate the old files to the app/assets directory.

我在这里找到了一些细节:
