將Devise升級到3.2.3后出現錯誤

Question

我執行了包更新，將Rails版本從3.2.13更改為3.2.17 ，提升了其他一些特性，並將Devise版本從1.5.0更改為3.2.3

我修復了一些Devise過時的方法和不兼容問題，並陷入了以下錯誤： uninitialized constant Users (NameError)

源自devise_for :users config/routes.rb devise_for :users路由助手

[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.

如何解決？

更新1

我修復了rails並將版本分別設計為3.2.13和1.5.0 ，然后更新了包（更新了許多gems），仍然遇到相同的錯誤。 我猜想devise和active_support寶石是無辜的。

正如我在Gemfile.lock中看到的，active_support依賴於兩個完全獨立的gem：

activesupport (3.2.13)
  i18n (= 0.6.1)
  multi_json (~> 1.0)

盡管Devise取決於以下寶石：

devise (1.5.0)
  bcrypt-ruby (~> 3.0)
  orm_adapter (~> 0.0.3)
  warden (~> 1.1)
    rack (>= 1.0)

無法想象他們中的哪一個出了什么問題

Answer 1

我開始一個接一個地修復gem版本，並發現一旦我修復了checker gem版本，錯誤就消失了。 我固定檢查器版本之前和之后bundle show的bundle show的差異輸出：

30c30
<   * checker (0.6.6)
---
>   * checker (0.6.2)

所以我最終從我的Gemfile中刪除了checker。

不幸的是，我沒有時間研究檢查器影響devise或active_support gems功能的方式。 也許以后。

我猜這是在CoreExt.constantize方法中，該方法重寫（？）相同的ActiveSupport :: Inflector方法
