CSS样式表未在Rails 3.2.8中应用

Question

For some reason i can't get the stylesheet correctly applied in products I'm following the book "Agile Web Development with Rails 4th Edition". 由于某种原因，我无法正确使用产品中的样式表，因此我正在阅读《使用Rails进行敏捷Web开发第四版》一书。 In the book, it looks like the background inside the products table alternates with pink and other color. 在书中，产品表中的背景看起来像是用粉红色和其他颜色交替显示的。

I'm newbie on rails i don't know so much about CSS or SCSS yet. 我是新手，对CSS或SCSS的了解还不多。

The file ../depot/app/assets/stylesheets/products.css.scss has the following: 文件../depot/app/assets/stylesheets/products.css.scss具有以下内容：

/* START_HIGHLIGHT */
.products {
  table {
    border-collapse: collapse;
  }

  table tr td {
    padding: 5px;
    vertical-align: top;
  }

  .list_image {
    width:  60px;
    height: 70px;
  }

  .list_description {
    width: 60%;

    dl {
      margin: 0;
    }
dt {
      color:        #244;
      font-weight:  bold;
      font-size:    larger;
    }

    dd {
      margin: 0;
    }
  }

  .list_actions {
    font-size:    x-small;
    text-align:   right;
    padding-left: 1em;
  }

  .list_line_even {
    background:   #e0f8f8;
  }
  .list_line_odd {
    background:   #f8b0f8;
  }
}
/* END_HIGHLIGHT */

This is ..app/views/products/index.html.erb 这是..app / views / products / index.html.erb

<h1>Listing products</h1>

<table>
<% @products.each do |product| %>
  <tr class="<%= cycle('list_line_odd', 'list_line_even') %>">

    <td>
      <%= image_tag(product.image_url, class: 'list_image') %>
    </td>

    <td class="list_description">
      <dl>
        <dt><%= product.title %></dt>
        <dd><%= truncate(strip_tags(product.description),
               length: 80) %></dd>
      </dl>
    </td>

    <td class="list_actions">
      <%= link_to 'Show', product %><br/>
      <%= link_to 'Edit', edit_product_path(product) %><br/>
      <%= link_to 'Destroy', product,
                  confirm: 'Are you sure?' ,
                  method: :delete %>
    </td>
  </tr>
<% end %>
</table>

<br />

<%= link_to 'New product', new_product_path %>

And ..app/views/layouts/application.html.erb 和..app / views / layouts / application.html.erb

<!DOCTYPE html>
<html>
<head>
  <title>Depot</title>
  <%= stylesheet_link_tag    "application", :media => "all" %>
  <%= javascript_include_tag "application" %>
  <%= csrf_meta_tags %>
</head>
<!-- START_HIGHLIGHT -->
<body class'<%= controller.controller_name %>'>
<!-- END_HIGHLIGHT -->

<%= yield %>

</body>
</html>

Answer 1

first of all 首先

<body class'<%= controller.controller_name %>'>

I think = is missing in here: 我认为这里缺少=：

<body class='<%= controller.controller_name %>'>

Second one 第二个

without manifest file (application.css) it is hard to say if you require that stylesheet but I suppose it should be: 没有清单文件（application.css），很难说是否需要该样式表，但我想应该是：

/*
 *= require_self
 *= require products
 */

or even better instead of require inside manifest file, include css for particular controller this way in layout: 甚至更好，而不是要求在清单文件内，以这种方式在布局中包括用于特定控制器的CSS：

<%= stylesheet_link_tag params[:controller] %>

also for best practice before you ask question, please ensure if in your browser that particular css is included. 同样，为了在您提出问题之前获得最佳实践，请确保您的浏览器中是否包含特定的CSS。 Inspect compiled css or document structure with developer tools. 使用开发人员工具检查已编译的CSS或文档结构。
