与Rails命名空间有关的未初始化常量错误 [英] Uninitialized constant error pertaining to Rails' namespaces

问题描述

我之前曾发布过此问题，但是更改了一些变量名并意识到我的错误为时已晚，因此该代码不会改变。

I posted this question before, but changed some variable names and realized my mistake too late, so this code is unaltered in any way.

错误：

路由错误未初始化的常量Firefighters Rails.root：

/ Users / Vladdy / Dropbox / dev / firestaff

Routing Error uninitialized constant Firefighters Rails.root:
/Users/Vladdy/Dropbox/dev/firestaff

这是来自 routes.rb 的相关错误位：

Here's the relevant, erroring bit from routes.rb:

  # get '/firefighters/dashboard' => 'firefighters#dashboard'
  namespace :firefighters do
    get '/dashboard'        => 'firefighters#dashboard' # Namely, this one.
    get '/dashboard/:date'  => 'firefighters#dashboard'
    get '/account'          => 'firefighters#account'
    get '/edit'             => 'firefighters#edit'
    get '/approve'          => 'firefighters#approve'
  end

如果我取消注释第1行，并发表评论 / dashboard ，仪表板可以通过 FirefightersController＃dashboard 正常加载。

If I uncomment line 1, and comment get /dashboard, the dashboard loads just fine through FirefightersController#dashboard.

我很努力地检查了我所有的模型名称是否都是单数： Accountant ， Engineer ， Firefighter 和我所有的控制器都是复数形式： AccountingController ， EngineeringController ，等等。

I painstakingly checked that all of my model names are singular: Accountant, Engineer, Firefighter and all of my controllers are plural: AccountingController, EngineeringController, etc.

这是错误的堆栈跟踪： http://pastebin.com / NpvY2EYy

Here is the stack trace of the error: http://pastebin.com/NpvY2EYy

我希望这是足够的信息。再次-SOS！我不知道如何诊断这个问题。如果有关系，我将使用ruby 2.3.0和rails 4.2.5

I hope this is enough information. Once again - SOS! I do no know how to diagnose this problem. If it matters, I'm using ruby 2.3.0 and rails 4.2.5

谢谢！

推荐答案

get '/firefighters/dashboard' => 'firefighters#dashboard'

有效，因为您的控制器是

Works because your controller is

class FirefightersController
end

这些

namespace :firefighters do
  get '/dashboard'        => 'firefighters#dashboard' # Namely, this one.
  get '/dashboard/:date'  => 'firefighters#dashboard'
  get '/account'          => 'firefighters#account'
  get '/edit'             => 'firefighters#edit'
  get '/approve'          => 'firefighters#approve'
end

不起作用，因为Rails期望使用模块您的控制器应该是

Don't work because rails is expecting a module so your controller should be

class Firefighters::FirefightersController

如果只对URL而不是应用程序的文件夹结构感到困扰，可以这样做

You could if you're only bothered about the url, not about the folder structure for your app do

scope '/firefighters' do
  get '/dashboard'        => 'firefighters#dashboard' # Namely, this one.
  get '/dashboard/:date'  => 'firefighters#dashboard'
  get '/account'          => 'firefighters#account'
  get '/edit'             => 'firefighters#edit'
  get '/approve'          => 'firefighters#approve'
end

在这种情况下，您可以将控制器原样保留

In which case you could leave your controller as it is.
