i'm working through hartl. ive got microposts section in chapter 10, instead of microposts have introduced hotels, , want add them separate address model, in this tutorial. having trouble - view field not appear enter address

<%= form_for(@hotel) |f| %>   <%= render 'shared/error_messages', object: f.object %>   <div class="field">     <%= f.text_field :title, placeholder: "new hotel title..." %>     <%= f.text_area :room_description, placeholder: "about room..." %>     <%= f.text_field :price, placeholder: "price?" %>     <%= f.check_box :include_breakfast%>     <%= f.label "include breakfast?", class: "checkbox inline" %> <br><% ["1 star", "2 star", "3 star", "4 star", "5 star"].each |item| %>   <%= f.radio_button :star_rate_hotel, item %> <%= item %><br /> <% end %> <% f.fields_for :address |address| %>     <%= f.text_field :street, placeholder: "street-address..." %>     <%= f.text_field :extended, placeholder: "extended-address..." %>     <%= f.text_field :locality, placeholder: "locality..." %>     <%= f.text_field :region, placeholder: "region..." %>     <%= f.text_field :country, placeholder: "country..." %> <% end %> <p> upload photo hotel(optionaly) <%= f.file_field :photo %>   </div>   <p>   <%= f.submit "post", class: "btn btn-large btn-primary" %> <% end %> 

my hotel_controller.rb

class hotelscontroller < applicationcontroller   before_filter :signed_in_user, only: [:create, :destroy]   before_filter :correct_user, only: :destroy    def create     @hotel = current_user.hotels.build(params[:hotel])     @hotel.build_address     if @hotel.save       flash[:success]="hotel created!"       redirect_to root_url     else       @feed_items = []       render 'static_pages/home'     end   end    def destroy     @hotel.destroy     redirect_to root_url   end    private    def correct_user     @hotel = current_user.hotels.find_by_id(params[:id])     redirect_to root_url if @hotel.nil?   end  end 

my user_controller.rb

class userscontroller < applicationcontroller   before_filter :signed_in_user, only: [:edit, :update, :index, :destroy]   before_filter :correct_user, only: [:edit, :update]   before_filter :admin_user, only: :destroy  def show   @user = user.find(params[:id])   @hotels = @user.hotels.paginate(page: params[:page], per_page: 3) end    def new     if signed_in?       redirect_to root_path     else     @user = user.new   end   end    def create     if signed_in?       redirect_to root_path     else     @user = user.new(params[:user])     if @user.save       sign_in @user       flash[:success]="welcome hotel advisor!"       redirect_to @user     else       render 'new'     end     end   end    def  edit   end    def update     if @user.update_attributes(params[:user])       flash[:success] = "profile updated"       sign_in @user       redirect_to @user     else       render 'edit'     end   end    def index     @users = user.paginate(page: params[:page], per_page: 7)   end    def destroy     user = user.find(params[:id])     if (current_user == user) && (current_user.admin?)       flash[:error] = "can not delete own admin account!"     else       user.destroy     flash[:success]="user destroyed"   end     redirect_to users_url   end    private      def correct_user       @user = user.find(params[:id])       redirect_to(root_path) unless current_user?(@user)     end      def  admin_user       redirect_to(root_path) unless current_user.admin?       end  end 

my question is: how display addresses?

you should create associated addresses in new method, create associations @ same time new object created. (to more precise, after object created).
