Question

I m new to rails. 我有我的控制者和看法。

When I view my html source, my body is empty. I put a debugger in my controller and my view and it hits both so I know it s being executed. Any idea what I m doing wrong? I have also installed bootstrap.

Thank you in advance. see below.

class ListController < ApplicationController
  def recent
    @page_title = @head_title="Lists"
  end
end

近期.html

    <ul class="tabs">
  <li class="active"><a href="#">Lorem</a></li>
  <li><a href="#">Ipsum</a></li>
  <li><a href="#">Dolor</a></li>
  <li><a href="#">Sit</a></li>
  <li><a href="#">Amet</a></li>
</ul>

简而言之,您没有<who> tag 或您申请中的任何观点内容?

仅添加以下文字:</html>:

<body>
  <%= yield %>
</body>

没有任何论点的yield将 gr掉从已表达的观点中的内容,并将之推到你的申请中。
