ruby-on-rails-3 - Rails - 从 3.0 迁移到 3.1

Question

我想通过从 3 迁移到 3.1 来帮助一个开源项目

但是我以前从未迁移过大型项目，所以我正在寻找一些建议？

这是项目 - https://github.com/locomotivecms/engine

谢谢，亚历克斯

Answer 1

这是一个“几乎可以工作”的 locomotivecms 代码，在 rails 3.1 上迁移：

https://github.com/lgs/engine/tree/rails-3.1

...它还没有准备好拉请求，

事实上，它错过了在所有相对路径中替换 /images/ whith /assets/ ...，无论如何它在 rails 3.1 服务器上启动并保持运行（尽管有很多“弃用警告”）：

Rails 控制台也可以正常工作：

Loading development environment (Rails 3.1.0.rc4)

这是我在尝试期间遵循的指南：

  更新：“无法就地修改 SafeBuffer”错误已解决

  更新 6 月 23 日 11：解决了“ArgumentError（参数数量错误（4 对 3））”将选项参数（第四个）添加到 set_session 到 lib/locomotive/session_store.rb b/lib/locomotive/session_store.rb 感谢 Nicholas Hubbard之前的回答。

Answer 2

从 GitHub 转发：

看起来 3.1 中的新会话需要 4 个参数： https ://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/middleware/session/cookie_store.rb第 61 行

def set_session(env, sid, session_data, 选项)

机车中的存储只需要三个： https://github.com/lgs/engine/blob/rails-3.1/lib/locomotive/session_store.rb第31行 def set_session(env, sid, session_data)

看起来我们也没有预料到的选项正在通过。
