ruby-on-rails - 带命名空间的 Rails 3 路由

Question

尝试访问以下 URL 时，我收到 404 错误页面 :

dev.mydomain.com/api

而我的 routes.rb 文件提到这条路线确实存在:

路由文件

constraints :subdomain => 'dev' do
  root :to => 'developers/main#index', :as => :developers
  namespace 'api', :as => :developers_api do
    root :to => 'developers/apidoc/main#index'
  end
end

rake 路线

         developers   /(.:format)      {:subdomain=>"dev", :controller=>"developers/main", :action=>"index"}
developers_api_root   /api(.:format)   {:subdomain=>"dev", :controller=>"api/developers/apidoc/main", :action=>"index"}

Controller

/app/controllers/developers/apidoc/main_controller.rb

class Developers::Apidoc::MainController < Developers::BaseController
  def index
  end
end

日志

[router]: GET dev.mydomain.com/api dyno=web.1 queue=0 wait=0ms service=14ms status=404 bytes=0
[web.1]: Started GET "/api"
[web.1]: ActionController::RoutingError (uninitialized constant Api::Developers)

Answer 1

我猜问题是你的路线指向 api/developers/apidoc/main但你的类(class)只有 Developers::Apidoc::MainController .您不应该使用 api 命名该路由或者将 Api 添加到 Controller 的命名空间 - Api::Developers::Apidoc::MainController .
