我正在尝试重新使用我编写的提供面板样式的html组件。类似的东西:
<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块。我想我可以这样做:
# /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>
我想做类似的事情:
#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=
一个块,但如果我删除它,那么它就不会输出任何内容。
有谁知道如何做我想在这里实现的目标?我想在我的网站上的许多地方重复使用这个面板html。

虽然上述两个答案都在起作用(好的是tony链接到的例子)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
完全正是我想要的东西:
# 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>

这是基于之前答案的替代方案。
在shared/_modal.html.erb
上创建部分:
<div class="ui modal form">
<i class="close icon"></i>
<div class="header">
<%= heading %>
</div>
<div class="content">
<%= capture(&block) %>
</div>
<div class="actions">
<div class="ui negative button">Cancel</div>
<div class="ui positive button">Ok</div>
</div>
</div>
在application_helper.rb
上定义您的方法:
def modal_for(heading, &block)
render(
partial: 'shared/modal',
locals: { heading: heading, block: block }
)
end
从任何视图中调用它:
<%= modal_for('My Title') do |t| %>
<p>Here is some content to be rendered inside the partial</p>
<% end %>

您可以使用捕获助手,甚至可以在渲染调用中内联:
<%= render 'my_partial',
:locals => { :title => "Some Title" },
:captured => capture { %>
<p>Here is some content to be rendered inside the partial</p>
<% } %>
并在共享/面板中:
<h3><%= title %></h3>
<div class="my-outer-wrapper">
<%= captured %>
</div>
将产生:
<h3>Some Title</h3>
<div class="my-outer-wrapper">
<p>Here is some content to be rendered inside the partial</p>
</div>

答案 3 :(得分:2)
根据接受的答案,这对我使用Rails 4的效果很好。
我们可以这样渲染一个面板:
= render_panel('Non Compliance Reports', type: 'primary') do
%p your content goes here!
这需要一个帮助方法和一个共享视图:
帮助方法(ui_helper.rb)
def render_panel(heading, options = {}, &block)
options.reverse_merge!(type: 'default')
options[:panel_classes] = ["panel-#{options[:type]}"]
render layout: '/ui/panel', locals: { heading: heading, options: options } do
capture(&block)
end
end
查看(/ui/panel.html.haml)
.panel{ class: options[:panel_classes] }
.panel-heading= heading
.panel-body
= yield
答案 4 :(得分:1)
如果你先将它分配给变量然后输出它,我认为它会起作用(只是做了快速的脏测试)。
<% foo = render :partial => '/shared/panel', :locals =>{:title => "Some Title"} do %>
<p>Here is some content to be rendered inside the panel</p>
<% end %>
<%= foo %>
