ruby-on-rails - 首字母缩略词不会正确复数导致循环依赖

Question

我想将我的 Controller 命名为 ESCsController，ESC 是相关首字母缩写词。我找到了 Rails inflection 文档，其中描述了实现此目的的方法。

http://api.rubyonrails.org/classes/ActiveSupport/Inflector/Inflections.html

Note: Acronyms that are passed to pluralize will no longer be recognized, since the acronym will not occur as a delimited unit in the pluralized result. To work around this, you must specify the pluralized form as an acronym as well:

acronym 'API'
camelize(pluralize('api')) #=> 'Apis'

acronym 'APIs'
camelize(pluralize('api')) #=> 'APIs'

我在将其添加到 environment.rb

后创建了我的 Controller 和模型

ActiveSupport::Inflector.inflections { |i| 
   i.acronym 'ESC'
   i.acronym 'ESCs'
}

在控制台中测试这些工作完美。 'ESC'.pluralize() 返回 ESCs 并且 'ESCs'.singularize() 按预期返回 ESC

分别通过rails generate model ESC和rails generate controller ESCs生成 Controller 和模型。这按预期创建了 escs_controller.rb 和模型 esc.rb。

在我的 routes.rb 我曾经有

resources :ESCs, path: '/parts/escs'

返回此错误:“ESCs”不是受支持的 Controller 名称。这可能会导致潜在的路由问题。请参阅 http://guides.rubyonrails.org/routing.html#specifying-a-controller-to-use

我最终将其更改为:

resources :ESCs, controller: 'escs', path: '/parts/escs'

但是，现在每当我尝试访问一个页面时，我都会遇到循环依赖错误:

Circular dependency detected while autoloading constant EscsController

有人知道这是怎么回事吗？看起来任何试图加载 Controller 的东西都没有看到它应该是 ESCsController 而不是 EscsController。我是 Rails 的新手，所以这可能是一个简单的问题......

我正在使用 Rails 4.0.2

这是完整堆栈跟踪的相关部分。

尝试将添加新变形的代码从 environment.rb 移动到 config/initializers/inflections.rb，然后重新加载服务器。此外，您不需要为路线指定 controller 选项，只需将其设为 resources :escs, path: '/parts/escs' 即可正常工作.
