Question

我正在使用Rails应用程序。我有一个设置下拉列表，它在本地主机上有效，但在heroku上不起作用。请帮助我解决此问题。我尝试了所有可能找到的解决方案，但仍然无法正常工作。我什至尝试对环境文件进行更改，但对我没有任何帮助。

production.rb

config.assets.compile = true
  config.serve_static_assets = true
  config.assets.digest = true

_navigation.html.erb

<li class="dropdown">
  <a href="" data-toggle="dropdown">Settings<b class="caret"></b></a>
    <ul class="dropdown-menu">
      <li><%= link_to "Change password", changepassword_path %></li>
        <% if current_user.superadmin? %>
          <li><a href="/main-admin/manage-users">Manage Users</a></li>
           <li><a href="/main-admin/general-settings">General Settings</a> 
           </li> 
          <% end %>            
     </ul>
    </li>
  <% end %>

application.html.erb

<!DOCTYPE html>
  <html>
    <head>
      <title>Freetoplay</title>
      <%= csrf_meta_tags %>
        <%= csp_meta_tag %>
          <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload' %>
            <%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
    </head>
    <body>
      <%= render 'layouts/navigation' %>
        <div class="bd">      
          <div class="container">
            <div class="row">
              <div class="col-lg-12 col-sm-12 col-xs-12">
                <ol class="breadcrumb">
                  <%= render_breadcrumbs :separator => " / " %>
                </ol>
              </div>
            </div>
          </div>
        </div>
        <%= render 'layouts/messages' %>
          <div class="container">
            <%= yield %>
          </div>
          <%= render 'layouts/footer' %>
    </body>
  </html>

我不知道这是否对您有帮助，但是我总是运行以下命令来更新Heroku的CSS。

RAILS_ENV=production bundle exec rake assets:precompile
git add public/assets
git commit -m "vendor compiled assets"
git push heroku master

下拉列表不适用于heroku
