Rails 命名空间路由到错误的控制器 [英] Rails namespaced routes to wrong Controller

问题描述

所以我才刚刚开始使用 RoR，并认为我也用 API 端点做一个基本的博客.问题是我的 api 请求似乎被路由到了错误的控制器，

So I'm just beginning with RoR and figured I do a basic blog with API endpoints aswell. The problem is that my api requests seem to be routed to the wrong controller,

我有以下作为我的 routes.rb

I have the following as my routes.rb

Blog::Application.routes.draw do

  namespace :api do
    namespace :v1 do
      resources :articles
    end
  end

end

我还有controllers/api/v1/articles_controller.rb，内容如下:

module API
  module V1    
    class ArticlesController < ApplicationController
      respond_to :json

      def index
        respond_with Article.all
      end

    end
  end
end

我的逻辑是，当我点击 http://localhost:3000/api/v1/articles 时，这应该是响应的控制器，但是实际响应的控制器是控制器的根目录 (controllers/articles_controller.rb) 而不是 /api/v1 路径中的根目录.当我移除实际响应的控制器时，我会得到 uninitialized constant Api::V1::ArticlesController .

My logic says that when I hit http://localhost:3000/api/v1/articles, this should be the Controller to respond, however the actual Controller that responds is the one in the root of controllers (controllers/articles_controller.rb) and not the one in the /api/v1 path. When I remove the Controller that actually responds, I'll get uninitialized constant Api::V1::ArticlesController instead.

即使 rake routes 也给了我预期的路由，但实际上到达这些端点失败了.rake routes 的输出如下:

Even rake routes gives me the expected routes, however actually hitting those endpoints fails. Output of rake routes is the following:

api_v1_articles GET    /api/v1/articles(.:format)          api/v1/articles#index
                    POST   /api/v1/articles(.:format)          api/v1/articles#create
 new_api_v1_article GET    /api/v1/articles/new(.:format)      api/v1/articles#new
edit_api_v1_article GET    /api/v1/articles/:id/edit(.:format) api/v1/articles#edit
     api_v1_article GET    /api/v1/articles/:id(.:format)      api/v1/articles#show
                    PUT    /api/v1/articles/:id(.:format)      api/v1/articles#update
                    DELETE /api/v1/articles/:id(.:format)      api/v1/articles#destroy

我在 SO 上发现的唯一类似问题是 嵌套命名空间路由出错控制器 但是，那里没有公认的答案，而且已经一年了.也许另一次尝试将有助于解决这个问题

The only similar question I found on SO is nested namespace route going to wrong controller however, there's no accepted answer there and it's been a year. Maybe another attempt will help resolve this issue

推荐答案

您的模块是 API，但 Rails 正在寻找 Api.Ruby 的模块区分大小写.

Your module is API, but Rails is looking for Api. Ruby's modules are case-sensitive.
