How do I get the current absolute URL in Ruby on Rails?

Question

How can I get the current absolute URL in my Ruby on Rails view?

The request.request_uri only returns the relative URL

Answer 1

you can use any one for rails 3.2:

request.original_url
or
request.env["HTTP_REFERER"]
or
request.env['REQUEST_URI']

I think it will work every where

"#{request.protocol}#{request.host}:#{request.port}#{request.fullpath}"
