how to fill twice id from routes rails

Question

i try to fill twice id in url, but when i send params twice id just one id fill the url id.

My route :

namespace :admin do
    resources :stores
    get "/:id/new_items"=> 'stores#new_items', as: :store_new_items
    post "/:id/create_items"=> 'stores#create_items', as: :store_create_items
    get "/:id/show_items/:id"=> 'stores#show_items', as: :store_show_items
    get "/:id/items/:id/new_items_sub" => 'stores#new_items_sub', as: :store_new_items_sub
    post "/:id/items/:id/create_items_sub" => 'stores#create_items_sub', as: :store_create_items_sub
    get "/:id/items/:id/show_items_sub/:id" => 'stores#show_items_sub', as: :store_show_items_sub
  end

my view :

<%= link_to "add new items", admin_store_new_items_sub_path(@store.id, @items.id), :class=> "btn" %>

i hope my url like this :

http://localhost:3000/admin/#{store.id}/items/#{items.id}/new_items_sub

but i get same id like this :

http://localhost:3000/admin/#{store.id}/items/#{store.id}/new_items_sub

please tell me when i'm wrong? thanks

Answer 1

you have to create neseted routes for that .have a look at http://guides.rubyonrails.org/routing.html#nested-resources

for example

resources :publishers do
  resources :magazines do
    resources :photos
   end
end

will accept routes /publishers/1/magazines/2/photos/3

Answer 2

Your params should be unique, so you can't pass more than one different :id params. Instead. you can do something like:

get '/:store_id/show_items/:id', as: :store_show_items

and in view:

<%= link_to 'show items', store_show_items_path(@store.id, @item.id) %>

Also, you should read more about Resources and Nested Resources in Rails, there's probably no need to complicate your life by creating each route independently.

Answer 3

You could refactor this to use nested routes like this (you may have to change controller method names):

namespace :admin do
  resources :stores do
    resources :items, :only => [:new, :create, :show] do
      resources :subs, :only => [:new, :create, :show]
    end
  end
end

This would give you a few url helpers like this: new_store_item_sub_path(@store.id, @item.id) for the new action and store_item_sub_path(@store.id, @item.id, @sub.id) for the show action.

Run rake routes to see what helpers and routes you have access to.

Answer 4

Your code can be DRYed up significantly. Hopefully this works; might need some tweaking:

namespace :admin do
    resources :stores do

        member do 
            get :new_items, as: :store_new_items
            post :create_items, as: :store_create_items
        end

        get "show_items/:id"=> 'stores#show_items', as: :store_show_items

        resources :items do 
            get :new_items_stub => 'stores#new_items_sub', as: :store_new_items_sub
            post :create_items_stub => 'stores#create_items_sub', as: :store_create_items_sub
            get "show_items_sub/:id" => 'stores#show_items_sub', as: :store_show_items_sub
        end
     end
  end

Nested Resources

The crux of your issue is that you're trying to pass the :id param twice

Fortunately, Rails has a solution to this, in the form of Nested Resources. These work by taking the "parent" id and prepending a singular prefix, such as :store_id, allowing you to use the :id param for another set of methods
