ruby-on-rails - Rails 使用 block 渲染部分内容

Question

我正在尝试重新使用我编写的提供面板样式的 html 组件。像这样的东西:

  <div class="v-panel">
    <div class="v-panel-tr"></div>
    <h3>Some Title</h3>
    <div class="v-panel-c">
      .. content goes here
    </div>
    <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div>
  </div>

所以我看到渲染需要一个 block 。我想我可以做这样的事情:

# /shared/_panel.html.erb
<div class="v-panel">
  <div class="v-panel-tr"></div>
  <h3><%= title %></h3>
  <div class="v-panel-c">
    <%= yield %>
  </div>
  <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div>
</div>

我想做这样的事情:

#some html view
<%= render :partial => '/shared/panel', :locals =>{:title => "Some Title"} do %>
  <p>Here is some content to be rendered inside the panel</p>
<% end %>

不幸的是，这不适用于此错误:

ActionView::TemplateError (/Users/bradrobertson/Repos/VeloUltralite/source/trunk/app/views/sessions/new.html.erb:1: , unexpected tRPAREN

old_output_buffer = output_buffer;;@output_buffer = '';  __in_erb_template=true ; @output_buffer.concat(( render :partial => '/shared/panel', :locals => {:title => "Welcome"} do ).to_s)
on line #1 of app/views/sessions/new.html.erb:
1: <%= render :partial => '/shared/panel', :locals => {:title => "Welcome"} do -%>
...

所以它显然不喜欢带有 block 的 = ，但如果我删除它，那么它就不会输出任何内容。

有谁知道如何实现我在这里想要实现的目标？我想在我网站上的许多地方重复使用此面板 html。

虽然上面的两个答案都有效(以及托尼链接到的示例)，但我最终在上面的帖子中找到了最简洁的答案(Kornelis Sietsma 的评论)

我猜render :layout正是我正在寻找的东西:

# Some View
<%= render :layout => '/shared/panel', :locals => {:title => 'some title'} do %>
  <p>Here is some content</p>
<% end %>

结合:

# /shared/_panel.html.erb
<div class="v-panel">
  <div class="v-panel-tr"></div>
  <h3><%= title -%></h3>
  <div class="v-panel-c">
    <%= yield %>
  </div>
</div>
