request.original_url in Fb-comments Div

Question

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

enter image description here

look the error ` <a class="external-link" href="#{request.original_url}" target="iframe_a">Facebook</a> ` did you try this — Rajarshi Das, Aug 27 '13 at 07:01
I entered the interpolation in the href field. This plugin does not have an iframe implementation. — Mini John, Aug 27 '13 at 07:05

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.
