如何为包括助手的资源创建单个GET路径？

Question

I have the following:

routes.rb

resources :splashes, only: [:index, :create, :destroy]
get '/splash', to: 'splashes#index'

>rake routes | grep splash
             splashes GET    /splashes(.:format)                                  splashes#index
                      POST   /splashes(.:format)                                  splashes#create
               splash DELETE /splashes/:id(.:format)                              splashes#destroy
                      GET    /splash(.:format)                                    splashes#index

However, when I try to use splash_url , it generates http://localhost:3000/splashes/1 .

I tried

get '/splash', to: 'splashes#index', as: 'splash'

But it gave

rake routes | grep splash
rake aborted!
ArgumentError: Invalid route name, already in use: 'splash' You may have defined two routes with the same name using the :as option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with resources as explained here: http://guides.rubyonrails.org/routing.html#restricting-the-routes-created

I tried to use the singular resource , but it doesn't generate an #index action, and you can't DELETE a specific splash row.

Just place your singular routes get statement before the resources statement,

get '/splash', to: 'splashes#index'
resources :splashes, only: [:index, :create, :destroy]

Now, the rake routs will give your the below result,

splash   GET    /splash(.:format)                                splashes#index
splashes GET    /splashes(.:format)                            splashes#index
         POST   /splashes(.:format)                            splashes#create
         DELETE /splashes/:id(.:format)                        splashes#destroy

By that above approach the delete and get routes get overrided based on the defintion sequence, because they both has the same named helpers spash_path . So, I suggest you to add named helper to custom get /spash routes like below,

resources :splashes, only: [:index, :create, :destroy]
get '/splash', to: 'splashes#index', as: 'splash_index'

So, now you will get a separate named routes splash_index for your custom get route. There's a another solution also,

resources :splashes, only: [:index, :create, :destroy]
resources :splash, only: [:index], controller: :splashes

So, that you will get a different named helper for your /spash routes,

splashes GET    /splashes(.:format)                           splashes#index
         POST   /splashes(.:format)                           splashes#create
splash DELETE /splashes/:id(.:format)                         splashes#destroy
splash_index GET    /splash(.:format)                         splashes#index
