下载XML文件而不是使用Builder进行渲染 [英] Downloading XML file instead of rendering using Builder

问题描述

我当前正在使用Builder进行自定义XML导出。但是，当用户单击按钮时，我希望下载.xml而不是进行渲染。

I am currently using Builder to make a custom XML export. However when the user clicks the button I want the .xml to download instead of rendering.

我尝试使用 send_data 而不是 render ，但是似乎已被构建器覆盖。

I have tried using send_data instead of render but that seems to be overridden by builder.

还使用ActiveAdmin（因此 member_action ）

Also using ActiveAdmin (hence the member_action)

在我的控制器中：

  member_action :show do
    @listing = Listing.find(params[:id])
    respond_to do |format|
      format.html
      format.xml 
    end
  end

链接到show.xml.builder

Links to show.xml.builder

xml.instruct!
xml.XMLopener { |b|
  b.....
  ......
  ....
  }

我看过下面的几个链接，但似乎无法正常工作。有任何想法吗？
显然，使用当前代码，它只是在渲染，效果很好。

I have looked at a few links below but I can't seem to get it working. Any ideas? Obviously with the current code it is just rendering, which works perfectly.

推荐答案

您是否尝试过这样的事情

Have you tried something like this

respond_to do |format|
  format.html
  format.xml { send_file :filename => 'mydoc.xml', :type=>"application/xml", :disposition => 'attachment' }
end
