预期的CSS“标题”Hartl的教程第5章练习

Question

我正在通过Michael Hartl's Ruby on Rails Tutorial Chapter 5 exercises工作，我一直在进行一项我无法弄清楚的失败测试。

我正在使用click_link问题并且所有大写字母都匹配，我相信所有其他文件都是正确的。我真的不确定这里有什么问题。我试过重启Spork。每当我注释掉第一次click_link测试时，它会为第二次测试提出错误，依此类推......请随意查看http://github.com/sambaek/sample_app处的代码。

有人可以帮帮我吗？非常感谢！

Answer 1

问题是因为layouts/footer和layouts/header中的链接无法访问。它们是可点击的规范，但它们只是转到#而不是正确的页面。如果你更正了这些链接，那么规范就可以了。

在app/views/layouts/_footer.html.erb：

<li><%= link_to "About",   '/about' %></li>
<li><%= link_to "Contact", '/contact' %></li>

在app/views/layouts/_header.html.erb：

 <li><%= link_to "Home",    '/' %></li>
 <li><%= link_to "Help",    '/help' %></li>

Answer 2

为什么不继续使用指定的路径路径变量（例如about_path）？
