【问题描述】:
CSS 不会加载到我的 rails 应用程序中。这是位于视图/产品中的 index.html.erb 文件:
<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 %>
然后我的 application.html.erb 文件位于视图/布局中。此文件应将 css 链接到 html。
<!DOCTYPE html>
<html>
<head>
<title>Depot</title>
<%= stylesheet_link_tag "application" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>
<%= yield %>
</body>
</html>
我位于 assets/stylesheets 中的 css 文件 products.css.scss 如下所示:
.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-color: #e0f8f8;
}
.list_line_odd {
background-color: #f8b0f8;
}
}
最后我的 application.css 文件如下所示:
/*
* This is a manifest file that'll automatically include all the stylesheets available in this directory
* and any sub-directories. You're free to add application-wide styles to this file and they'll appear at
* the top of the compiled file, but it's generally better to create a new file per style scope.
*= require_self
*= require_tree .
*/
在我看来一切正常,据我了解,application.css 收集了所有其他 css 文件,因此您不必手动链接它们。我说的对吗?
这也是我加载页面时的服务器日志:

为什么我的应用没有显示任何 CSS?
【问题讨论】:
-
您确定资产管道已启用吗?看起来不像。
-
我很确定它是。在文件 config/application.rb 中有 config.assets.enabled = true 行。有没有可以输入检查的命令?
-
all.css是你写的css文件吗?
-
当我尝试在浏览器中访问 all.css 文件时遇到路由错误。
-
这是一个全新的 Rails 3.1+ 应用程序,还是从以前的版本迁移而来?
