如何将现有的旧rails项目更新为更新版本

Question

I have a Rails project using rails 3.0.7.

I want to update it to 3.1.0.rc6.

However the directory structure of these are really different,

is there an automatic way to transfer the directory structure? Thank you very much.

Answer 1

I'm not aware of an automated way to update Rails apps to 3.1, but I found David Rice's blog entry about to be a pretty good overview of the steps involved. You can find the overview at: http://davidjrice.co.uk/2011/05/25/how-to-upgrade-a-rails-application-to-version-3-1-0.html

我创建了一个github项目来跟踪默认生成的rails项目布局的差异https://github.com/pmq20/rails-diff-track
