Question

我有resources :shops

会产生/shops，/shops/:id等

我知道我可以使用

来收集集合或成员

resources :shops do
  scope ":city" do
   # collection and members
  end
end

或之前用

做

scope ":city" do
 resources :shops
end

但是我无法弄清楚如何让路线成为所有成员（包括标准的REST成员）和集合，就像这样

/shops/:city/

/shops/:city/:id

Answer 1

根据您的use case和问题，您尝试使用逻辑上错误的路线。你在城里有商店，而不是商店内的城市。

首先，您应该规范化您的数据库。您应该创建另一个表cities，并将city属性替换为city_id表中的shops。

has_many和belongs_to之间需要cities和shops关联。

# Models
class City < ActiveRecord::Base
  has_many :shops
  ... # other stuff
end

class Shop < ActiveRecord::Base
  belongs_to :city
  ... # other stuff
end

路线

resources :cities do
  resources :shops
end

它将生成如下路线：

               POST     /cities/:city_id/shops(.:format)          shops#create
new_city_shop  GET      /cities/:city_id/shops/new(.:format)      shops#new
edit_city_shop GET      /cities/:city_id/shops/:id/edit(.:format) shops#edit
    city_shop  GET      /cities/:city_id/shops/:id(.:format)      shops#show
               PATCH    /cities/:city_id/shops/:id(.:format)      shops#update
               PUT      /cities/:city_id/shops/:id(.:format)      shops#update
               DELETE   /cities/:city_id/shops/:id(.:format)      shops#destroy

从逻辑上讲，这些路线将显示特定商店所在的城市。

<强>命名空间

您可以考虑加入namespace

由于您正试图为商店提升cities（IE，我想您想在Sao Paulo中展示商店），您可以这样做：

#config/routes.rb
namespace :shops do
   resources :cities, path: "", as: :city, only: [:index] do #-> domain.com/shops/:id/
      resources :shops, path: "", only: [:show] #-> domain.com/shops/:city_id/:id
   end
end

这将允许您创建一个单独的控制器：

#app/controllers/shops/cities_controller.rb
Class Shops::CitiesController < ApplicationController
   def index
      @city = City.find params[:id]
   end
end

#app/controllers/shops/shops_controller.rb
Class Shops::ShopsController < ApplicationController
   def show
      @city = City.find params[:city_id]
      @shop = @city.shops.find params[:id]
   end
end

这将确保您能够创建所需的路由结构。命名空间做了两件重要的事情 -

确保您拥有正确的路由结构
