Fb-comments Div中的request.original_url [英] request.original_url in Fb-comments Div

问题描述

我正在尝试在我的应用程序（Rails4）中添加Facebook评论。

评论的Div是

 < div class =fb-commentsdata-href ={URL_HERE}data-width =570>< / div> 
  

其中{URL_HERE}我需要

  request.original_url 
  

或当前页面的URL。 / p>

我如何设置？

我尝试了

data-width =570>< / div>

但我从Facebook收到错误

解决方案

好的，我知道了

 <％= request.original_url％> 
  

对于任何绊脚石的人：

对于 Rails 3.2 或 Rails 4 ，您应该使用 request.original_url 获取当前的URL。 a>。

对于Rails 3：您需要＃{request.protocol}＃{request.host_with_port} ＃{request.fullpath}，因为 request.url 现已弃用。

对于Rails 2：您需要 request.url 而不是 request.request_uri 。这将协议（通常是http：//）与主机相结合，request_uri将为您提供完整的地址。

I'm trying to include Facebook Comments in my app (Rails4).

The Div for the comments is

<div class="fb-comments" data-href="{URL_HERE}" data-width="570"></div>

where {URL_HERE} i need

request.original_url

or the url of the current page.

How can i set this up ?

I tried

<div class="fb-comments" data-href="#{request.original_url}" data-width="570"></div>

But i'm getting a error from facebook

解决方案

OK, i got it. Didn't need to use interpolation here.

<%= request.original_url %>

For anyone who stumbles upon this:

For Rails 3.2 or Rails 4 you should use request.original_url to get the current URL. More detail.

For Rails 3: You want "#{request.protocol}#{request.host_with_port}#{request.fullpath}", since request.url is now deprecated.

For Rails 2: You want request.url instead of request.request_uri. This combines the protocol (usually http://) with the host, and request_uri to give you the full address.
