Rails在Heroku中缺少模板用戶/顯示和用戶/索引

當我在開發中本地運行它時，我可以很好地查看所有用戶和每個用戶。Rails在Heroku中缺少模板用戶/顯示和用戶/索引

當我嘗試查看所有用戶或從我的側邊欄Heroku服務器部分特定的用戶，我得到一個丟失的模板錯誤，即使我有兩個users/index和users/show。

在StackOverflow上進行了一些搜索之後，我意識到我擁有的用戶文件夾實際上是'用戶'，並帶有大寫的u。我想將文件夾重命名爲users後，我的問題將得到解決，但它仍然是相同的。

佈局/ _sidebar.html.erb：

<% if user_signed_in? -%> 
     <li><%= link_to(current_user) do |profile| %> 
     <i class="glyphicon glyphicon-user"></i> My Profile 
     <% end %> 
     </li> 
    <% end %> 
    <li><%= link_to(users_path) do |users| %> 
     <i class="glyphicon glyphicon-eye-open"></i> All Users 
    <% end %> 
    </li>

用戶/ index.html.erb

<h1>All Users</h1> 
<% @users.order("name ASC").each do |user| %> 
    <div class="clip row clearfix"> 
     <div class="container"> 
      <h2> 
      <%= link_to user.name, user %> 
      </h2> 
     </div> 
    </div> 
<% end %>

控制器/ users_controller.rb

class UsersController < ApplicationController 
    before_action :signed_in?, only: [:index, :edit, :update, :destroy, 
             :following, :followers] 

    def create 
     @user = User.new(params[:user]) 
     if @user.save 
      UserMailer.welcome_email(@user).deliver_now 
     end 
    end 

    def index 
     @users = User.all 
    end 

    def show 
     @user = User.find(params[:id]) 
    end 

    def following 
     @title = "Following" 
     @user = User.find(params[:id]) 
     @users = @user.following(page: params[:page]) 
     render 'show_follow' 
    end 

    def followers 
     @title = "Followers" 
     @user = User.find(params[:id]) 
     @users = @user.followers(page: params[:page]) 
     render 'show_follow' 
    end 
end

我想你忘了把適當的文件推送到heroku。但是如果沒有看到日誌就很難說清楚。 –

你的意思是'git push heroku master'之後的日誌嗎？ –

顯示heroku日誌：'$ heroku日誌' – uday

它看起來像日誌有點不完整，真的有助於診斷問題。您可以使用heroku logs -t來記錄日誌並在出現整個錯誤時停止它們。

還是有幾件事情從你貼什麼要注意的：

link_to(user_path(current_user))

您需要的路徑助手（user_path）添加到的link_to助手和當前用戶對象傳遞給這條道路幫手在你的邊欄部分。

雖然它不會解決這個問題，但我也建議將.order("name ASC")放在控制器的索引操作中，而不是在您的視圖中。我假設你的查看代碼是app/views/users/。

此外，我可以看到您使用Webrick作爲您的網絡服務器。 Heroku和幾乎所有人都建議不要使用這個網絡服務器 - 據我所知，它甚至不會隨即出現Rails 5版本。改用Puma來代替。

你的代碼中最後一件事情還不清楚：如果沒有用戶會發生什麼（哪裏不會有新的Heroku安裝）？

Rails在Heroku中缺少模板用戶/顯示和用戶/索引
