但我之前从未有过迁移大型项目所以我正在寻找一些建议吗？

谢谢，Alex

Answer 1

这里是一个“几乎正常工作”的locomotivecms代码，迁移到rails 3.1：

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

......还没有为拉请求做好准备，

实际上它错过了在所有相对路径中替换/ images / whith / assets / ... 无论如何，它开始并熬夜（尽管许多“DEPRECATION WARNING”），在rails 3.1服务器：

lsoave@ubuntu:~/rails/github/engine$ rails s

Rails控制台也可以正常工作：

lsoave@ubuntu:~/rails/github/engine$ rails c

这是我在尝试期间遵循的指南：

更新： “无法修改SafeBuffer”错误已解决

更新jun 23 11：解决了“ArgumentError（错误的参数数量（4 for 3））”将选项param（第四个）添加到set_session到lib / locomotive / session_store.rb b / lib / locomotive / session_store.rb 感谢Nicholas Hubbard先前的回答。

Answer 2

从GitHub重新发布：

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，options）

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

看起来我们没有想到也会传递选项。
