Ruby on rails 在Rails4中下载公共文件

我正在使用Rails-4.0.2、ruby 2.1.0，并且有几个公共文件，它们在我的app/public文件夹中。在index.html视图中，我下载了以下表单

<table class="table table-condensed table-striped" style="border-collapse: collapse;
      border-spacing: 0; width: 50%;">
  <tbody>
    <% @reports.each do |report| %>
      <tr>
        <td><%= report.title %></td>
        <td> <a href=<%= "#{report.url}"%>> Download </a></td>
      </tr>
    <% end %>
  </tbody>

这只是公用文件夹中的静态文件，如何在生产中下载

以下是我的配置文件：

提前谢谢

该文件不会在生产中交付，因为

# Disable Rails's static asset server (Apache or nginx will already do this).
config.serve_static_assets = false

我建议您使用真正的Web服务器（如nginx或Apache）来交付静态文件！（作为配置nginx或Google的起点）
