Rails 2.3.7 的 content_for 问题

我有一个应用程序，我想使用“content_for”渲染菜单以及左侧导航栏，然后其余部分是我的文档的正文。然而，在我的左栏和菜单区域中，html 标记被转义。我看到一篇关于在产量之前使用 raw 的帖子，但这没有帮助。

在花了相当长的时间尝试在真实的应用程序中诊断它之后，我创建了一个非常简单的测试，并且能够用最少的代码让它完成相同的任务。这是我所拥有的：

layouts.application.erb

  <body>
     <section id="page">
        <header>
          <nav class="clear"><%= raw yield :navigation %></nav>
        </header>

       <%= yield %>

     </section>
  </body>
</html>

pages/index.html.erb

<% content_for :navigation do %>
  <ul><li><%= link_to 'New page', new_page_path %></li></ul>
<% end %>

<h1>Listing pages</h1>

<table>
  <tr>
    <th>Title</th>
    <th>Body</th>
  </tr>

<% @pages.each do |page| %>
  <tr>
    <td><%=h page.title %></td>
    <td><%=h page.body %></td>
    <td><%= link_to 'Show', page %></td>
    <td><%= link_to 'Edit', edit_page_path(page) %></td>
    <td><%= link_to 'Destroy', page, :confirm => 'Are you sure?', :method => :delete %></td>
  </tr>
<% end %>
</table>

当我在浏览器中点击页面时，导航部分没有正确转义（实际上是链接，但不是列表，这对菜单来说很重要:)）

这是来自全新的 Rails使用脚手架生成的代码的项目，该代码仅被修改以将默认链接移动到导航部分（并添加该部分）。

原文

I have an application where I want to render the menu using "content_for" as well as a left navigation bar and then the rest be the body of my document. However, in my left bar and menu regions, the html markup is being escaped. I saw a post regarding using raw before the yield, but that didn't help.

After spending quite some time trying to diagnose it within the real app, I created a VERY simple test and was able to get it to do the same with minimal code. Here is what I have:

layouts.application.erb

  <body>
     <section id="page">
        <header>
          <nav class="clear"><%= raw yield :navigation %></nav>
        </header>

       <%= yield %>

     </section>
  </body>
</html>

pages/index.html.erb

<% content_for :navigation do %>
  <ul><li><%= link_to 'New page', new_page_path %></li></ul>
<% end %>

<h1>Listing pages</h1>

<table>
  <tr>
    <th>Title</th>
    <th>Body</th>
  </tr>

<% @pages.each do |page| %>
  <tr>
    <td><%=h page.title %></td>
    <td><%=h page.body %></td>
    <td><%= link_to 'Show', page %></td>
    <td><%= link_to 'Edit', edit_page_path(page) %></td>
    <td><%= link_to 'Destroy', page, :confirm => 'Are you sure?', :method => :delete %></td>
  </tr>
<% end %>
</table>

When I hit the page in a browser, the navigation part is not escaped properly (actually the link is, but not the list, which is kinda important with menus:) )

This is from a brand new rails project using scaffold generated code which was modified only to move the default link up into the navigation section (and adding that piece in).
