hello 大家,我正在阅读 rails 4 的教程,在进行到第八章测试 authentication_pages 时,总是通不过,查了很多资料都不行,我也在 stackover 发了一篇帖子,帖子地址:http://stackoverflow.com/questions/25824363/testing-with-rspec-couldnt-get-over-it-any-one 一晚上了没人回。呵呵,所以回到咱们中国社区这来看看,请高手帮我看看。以下时细节:

LZ, 最好附上 github 代码链接

hi 谢谢你的尝试,我刚发现我最新的几个文件没有 commit 上去,所以你测试才是通过的,稍等等我找到方法把这些 commit 上去吧,尝试了几下不行 呵呵

已经 commit 了,谢谢你啦,麻烦你在帮忙看看

问题在于你的代码还没写完,_header.html.erb 中 还没有定义 "Profile" 和 "Sign out", 所以登录成功以后找不到上面两个连接。

<header class="navbar navbar-fixed-top navbar-inverse">
  <div class="navbar-inner">
    <div class="container">
      <%= link_to "Snail Travel Season", root_path, id: "logo" %>
      <nav>
        <ul class="nav pull-right">
          <li><%= link_to "Home",    root_path %></li>
          <li><%= link_to "help",    help_path %></li>
          <li><%= link_to "Sign in", signin_path %></li>
        </ul>
      </nav>
    </div>
  </div>
</header>

继续往后面看,写到代码 8.24,所有测测试就可以通过了。

代码 8.24:根据登录状态改变导航链接 app/views/layouts/_header.html.erb”

哈哈 谢谢,明白了,但是我看作者说的测试可以通过了,结果我一直通不过。
