导轨 - 从3.0到3.1

Question

我想从3迁移到3.1

助阵开源项目迁移，但我从来没有迁移一个大的项目之前，所以我要寻找一些建议？

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

谢谢，亚历克斯

Answer 1

这是一个 “几乎工作” locomotivecms代码，迁移on Rails的3.1：

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

...它没有准备好拉请求，

事实上，它错过了在所有的relati中替换/ images/whith/assets /五个路径......，反正 它启动和熬夜（尽管有许多 “弃用警告”），在轨道上3.1服务器：

Rails的控制台正常工作，以及：

这是引导我跟着我尝试在：

  更新： “不能到位修改SafeBuffer” 错误解决

  UPDATE 11年6月23日： 解决 “引发ArgumentError（错误的参数数目（4 3））” 添加选项参数（第四），以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转贴：

它看起来像在3.1的新会话需要4个PARAMS： https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/middleware/session/cookie_store.rb线61

高清set_session（ENV，SID，session_data是，期权）

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

看起来正在传递的选项也是我们并不期待的。
