Get the Current url in ruby on rails

request.refererrequest.fullpathrequest.fullpath.split("?")[0]request.referer or request.env['HTTP_REFERER'] your controller to get the referer url. 

--------------------
request.original_url
request.url
request.host_with_port
<link rel="canonical" href="<%= request.url %>" />
<%=request.path%>
How can I get the current absolute URL in my Ruby on Rails view?
The request.request_uri only returns the relative URL.
request.env['REQUEST_URI']

 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
