ruby-on-rails-3 - rails-upgrade - 将 rails2 应用程序升级到 rails3

Question

我在 rails2 中有一个现有项目，我需要将其升级到 rails3。

我听说过一些关于 rails-upgrade 的东西，但还没有使用过。

当我尝试使用 rails-upgrade check 时，它会生成如下错误:

$ rails-upgrade check
/usr/lib/ruby/gems/1.8/gems/rails-upgrade-0.0.2/lib/rails-upgrade/upgraders/routes.rb:28: undefined method `cattr_accessor' for RailsUpgrade::Upgraders::RouteRedrawer:Class (NoMethodError)
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `gem_original_require'
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `require'
    from /usr/lib/ruby/gems/1.8/gems/rails-upgrade-0.0.2/lib/rails-upgrade.rb:12
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `gem_original_require'
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `require'
    from /usr/lib/ruby/gems/1.8/gems/rails-upgrade-0.0.2/bin/rails-upgrade:7
    from /usr/bin/rails-upgrade:19:in `load'
    from /usr/bin/rails-upgrade:19

任何人请告诉我如何将我的应用程序升级到 rails3。

Answer 1

我通过在旧项目中创建新的 Rails 项目来进行 Rails 升级。

在创建过程中，您应该检查那些应该被覆盖的文件之间的区别。

对我来说，这是更新我的 Rails 项目的最快方式。
