How to manage the path to a template

Question

In my view directory I have two subdirectory master/hotels and cruds. In cruds I have several files(new, index, edit, show). master only has index file. Now I set "index" in cruds as root and I can link directory to "new" by add this path in a button like this:

= link_to "new", url_for(new_master_hotels_path), class: "btn btn-white btn-sm"

The problem is, I cannot link to other path like edit_master_hotels_path ore show_show_hotels_path and I don't know why "new" can and others cannot. I use wice_grid plugin in my project. my routes here

# -*- coding: utf-8 -*-
SptHunter::Application.routes.draw do
post "versions/:id/revert" => "versions#revert", :as => "revert_version"
devise_for :admin_users
resources :flights

mount RailsAdmin::Engine => '/rails_admin', :as => 'rails_admin'
resources :dashboard, only: [:index]
root to: 'master/hotels#index'
resources :reservations do
 collection do
  get 'callcenter'
 end
end

concern :importable do
 collection do
  post :import
 end
end

#resources :products do
#  collection { post :import }
#end
# マスタ
namespace :master do
  # マスタ（商品）
 resources :hotels, concerns: [:importable]
 resources :flights, concerns: [:importable]
 resources :options, concerns: [:importable]
 resources :events, concerns: [:importable]
 resources :products, concerns: [:importable]
 resources :hotel_room_stocks, concerns: [:importable]

 # マスタ（取引先）
 resources :agencies, concerns: [:importable]
 resources :companies, concerns: [:importable]
 resources :clients, concerns: [:importable]

 # マスタ（設定）
 resources :product_categories, concerns: [:importable]
 resources :delivery_categories, concerns: [:importable]
 resources :airports, concerns: [:importable]
 resources :areas, concerns: [:importable]
 resources :prefectures, concerns: [:importable]
 resources :hotel_rooms, concerns: [:importable]

 # マスタ（社内）
 resources :admin_users, concerns: [:importable]
 resources :admin_news, concerns: [:importable]

 end
end

and my view structure is: -master/hotels(index) -cruds(new,form,show,edit,index) hope it help.

Answer 1

If you have subdirectory a & b, your routes should accommodate them like this:

#config/routes.rb
namespace 'subdirectory' do
   #routes here
   resources :demo
end

This basically means you have to maintain the resource-based Rails routing infrastructure within the subdomain, meaning your routes will basically be the same as if you didn't have a subdirectory set up.

Update

Surely you could fix your routes to be DRY like this:

namespace :master do
  # マスタ（商品）
 resources :hotels, :flights, :options, :events, :products, :hotel_room_stocks, concerns: [:importable]

 # マスタ（取引先）
 resources :agencies, :companies, :clients, concerns: [:importable]

 # マスタ（設定）
 resources :product_categories, :delivery_categories, :airports_categories, :areas, :prefectures, :hotel_rooms, concerns: [:importable]

 # マスタ（社内）
 resources :admin_users, :admin_news concerns: [:importable]

 end
