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

if you want to be specific, meaning, you know the path you need:

link_to current_path(@resource, :only_path => false), current_path(@resource)

Answer 2

You could use url_for(only_path: false)

Answer 3

This works for Ruby on Rails 3.0 and should be supported by most versions of Ruby on Rails:

request.env['REQUEST_URI']

Answer 4

I needed the application URL but with the subdirectory. I used:

root_url(:only_path => false)

Answer 5

You can set a variable to URI.parse(current_url), I don't see this proposal here yet and it works for me.

Answer 6

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}"
