您的控制器将如下所示:

Your controller would then look something like:

class WelcomeController < ApplicationController
  def iframe
    load_channels
    render :partial => "news", :layout => "iframe"
  end
end

然后创建一个新的精简版式，名为"_iframe.html.erb"(或.haml或您使用的任何格式)，仅包含资产和收益"(如果复制应用程序版式并删除部件，则很容易您不需要).

And then you create a new stripped down layout named "_iframe.html.erb" (or .haml or whatever you use) containing only your assets and the "yield" (easy if you copy your application layout and remove the parts you don't need).
