尝试按照本书中的本教程进行操作,但提供的图像未显示在我/views/layouts/ads.html.erb
看起来像这样的页面上
<!doctype HTML>
<html>
<head>
<title>Ads: <%= controller.action_name %></title>
<%= stylesheet_link_tag 'default.css' %>
</head>
<body>
<div id="wrapper">
<div id="header">
<div>
<h1>MeBay</h1>
<ul id="nav">
<li><a href="/ads/">All Ads</a></li>
</ul>
</div>
</div>
<div id="content">
<%= yield %>
</div>
<div id="clearfooter"></div>
</div>
<div id="footer"></div>
</body>
</html>
中的 CSS/app/assets/stylesheets
看起来像这样
html, body { height: 100%; }
body { background-color: #e6dacf; background-image: url('/images/bg.png'); background-position: top center; background-repeat: repeat-y; font-family: "Trebuchet MS", Arial, san-serif; font-size: 14px; margin: 0; padding: 0; text-align: center; }

我把提供的图像放在/app/assets/images
这就是它应该的样子,也是它对我的样子
