Question

不知怎的，我得到了这个路由错误。我没有看到解决方案

我的控制器：

class SubscribersController < ApplicationController
  def signup
    blabla...
  end
  etc.....
end

我的routes.rb

Rails.application.routes.draw do

  get 'signup' => 'subscribers/#signup'
  resources :events
  resources :subscribers

  root to: 'events#index'

end

所以如果我去http://0.0.0.0:3000/signup 我收到错误：RoutingError uninitialized constant Subscribers

Answer 1

/代表命名空间或文件夹，#用于路由中的操作。您只需删除/，因为signup是SubscribersController下的操作：

get 'signup' => 'subscribers#signup'

Answer 2

由于您有resources :subscribers这样的最佳方式来声明非CRUD操作的路由，例如

resources :subscribers do
  member { post :foo } # if is member (operation on single obj) with http post
  collection { get :bar } # for collection with http get
end

所以问题的最佳解决方案是

Rails.application.routes.draw do
  resources :events

  resources :subscribers do
      collection { get :signup }
    end

  root to: 'events#index'
end
