コマンド
１文です。
rails g controller Rooms index new create listing pricing description photo_upload amenities location update

app\controllers\rooms_controller.rb

class RoomsController < ApplicationController
  before_action :set_room, except: [:index, :new, :create]
  before_action :authenticate_user!, except: [:show]

  def index
     @rooms = current_user.rooms
  end

  def new
    @room = current_user.rooms.build
  end

  def create
    @room = current_user.rooms.build(room_params)
    if @room.save
      redirect_to listing_room_path(@room), notice: "保存しました。"
    else
      flash[:alert] = "問題が発生しました。"
      render :new
    end
  end

  def show
  end

  def listing
  end

  def pricing
  end

  end

  def photo_upload
  end

  def amenities
  end

    new_params = room_params

    if @room.update(new_params)

    end
    redirect_back(fallback_location: request.referer)
  end

  private

    def set_room
      @room = Room.find(params[:id])
    end

    def room_params
      params.require(:room).permit(:home_type, :room_type, :accommodate, :bed_room, :bath_room, :listing_name, :summary, :address, :is_tv, :is_kitchen, :is_air, :is_heating, :is_internet, :price, :active)
    end

end

「app\views\rooms」フォルダに「show.html.erb」ファイルを新規作成します。
今は空のファイルで大丈夫です。

記述追加　config\routes.rb(17行目)

  resources :rooms, except: [:edit] do
    member do
      get 'listing'
      get 'pricing'
      get 'description'
      get 'photo_upload'
      get 'amenities'
      get 'location'
    end
  end

config\routes.rb
自動で追加された記述は削除します。

Rails.application.routes.draw do

  # ルートを　app\views\pages\home.html.erb　に設定
  root 'pages#home'

  devise_for :users, 
              path: '', 
              path_names: {sign_up: 'register', sign_in: 'login', edit: 'profile', sign_out: 'logout'},
              controllers: {registrations: 'registrations'}

  get 'pages/home'
  get '/dashboard', to: 'users#dashboard'
  get '/users/:id', to: 'users#show', as: 'user'
  
  post '/users/edit', to: 'users#update'

  resources :rooms, except: [:edit] do
    member do
      get 'listing'
      get 'pricing'
      get 'description'
      get 'photo_upload'
      get 'amenities'
      get 'location'
    end
  end
