導軌 - 從3.0到3.1

Question

我想從3遷移到3.1

助陣開源項目遷移，但我從來沒有遷移一個大的項目之前，所以我要尋找一些建議？

這是項目 - https://github.com/locomotivecms/engine

謝謝，亞歷克斯

Answer 1

這是一個 「幾乎工作」 locomotivecms代碼，遷移on Rails的3.1：

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

...它沒有準備好拉請求，

事實上，它錯過了在所有的relati中替換/ images/whith/assets /五個路徑......，反正 它啓動和熬夜（儘管有許多 「棄用警告」），在軌道上3.1服務器：

Rails的控制檯正常工作，以及：

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

這是引導我跟着我嘗試在：

• http://davidjrice.co.uk/2011/05/25/how-to-upgrade-a-rails-application-to-version-3-1-0.html

  更新： 「不能到位修改SafeBuffer」 錯誤解決

  UPDATE 11年6月23日： 解決 「引發ArgumentError（錯誤的參數數目（4 3））」 添加選項參數（第四），以set_session到LIB/locomotive/session_store.rb b/lib/locomotive/session_store.rb 感謝Nicholas Hubbard先前的回答。

Answer 2

從GitHub轉貼：

它看起來像在3.1的新會話需要4個PARAMS： https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/middleware/session/cookie_store.rb線61

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

機車商店只需要三個： https://github.com/lgs/engine/blob/rails-3.1/lib/locomotive/session_store.rb第31行 def set_session（env，sid，session_data）

看起來正在傳遞的選項也是我們並不期待的。
