與初始化常量（NameError）與名稱空間的自定義Devise類

Question

我跟着一些教程來爲我的應用程序創建一個API。我把從Devise註冊和會話控制器繼承的自定義控制器。我瀏覽了大量的問題/答案，無法解決我的問題。

我的解決方案適用於我的Ubuntu VM，但不適用於ec2實例。下面是新一類的第一行：

class Api::V1::SessionsController < Devise::SessionsController 

和routes.rb中的一些代碼：

devise_for :users 

namespace :api do 
namespace :v1 do 
devise_scope :user do 
    post 'registrations' => 'registrations#create', :as => 'register' 
    post 'sessions' => 'sessions#create', :as => 'login' 
    delete 'sessions' => 'sessions#destroy', :as => 'logout' 
end 
get 'tournaments' => 'tournaments#index', :as => 'tournaments' 
end 
end 

我定製的控制器是在API/V1目錄，並正確顯示路由。錯誤的是（與軌跡的一部分）：

  
ActionController::RoutingError (uninitialized constant Api):

    actionpack (3.2.13) lib/action_dispatch/middleware/flash.rb:242:in `call' 

並獲取服務器的運行，我曾在applications.rb設置這些標誌：

# Code is not reloaded between requests 
config.cache_classes = false 

# Full error reports are disabled and caching is turned on 
config.consider_all_requests_local  = true 
config.action_controller.perform_caching = false 

Answer 1

試試這個：

devise_scope :user do 
    post 'registrations' => 'api/v1/registrations#create', :as => 'register' 
    post 'sessions' => 'api/v1/sessions#create', :as => 'login' 
    delete 'sessions' => 'api/v1/sessions#destroy', :as => 'logout' 
end 

namespace :api do 
    namespace :v1 do 
    get 'tournaments' => 'tournaments#index', :as => 'tournaments' 
    end 
end 

一定要重新啓動服務器修改routes.rb中

後確保您的控制器是在直接ory api/v1（只能使用小寫字母）
