ユーザーにルーティングする

Question

私は3ヶ月の停止からコードを覚えようとしていますので、新しいプロジェクトでlink_toを追加しようとするとデバイスのユーザーになりますsign_in page..keptこのエラーが発生しました。

NameError in Topics#index 
undefined local variable or method `new_user_session' for #<#<Class:0x74e5db0>:0x54af248> 

route.rb

Rails.application.routes.draw do 
    resources :topics 
    devise_for :admins, ActiveAdmin::Devise.config 
    ActiveAdmin.routes(self) 
    devise_for :users 

    root 'topics#index' 

は、ここではそれは私が推測するタイプミスだ私のルート

<div id="pre_header" class="visible-lg" style="background-color:#E4AB7E; height:5px;"></div> 

Answer 1

<li><%= link_to 'Log Masuk',new_user_session_path %></li>
