How do I get the current absolute URL in Ruby on R

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}"

Answer 2

It looks like request_uri is deprecated in Ruby on Rails 3.

Using #request_uri is deprecated. Use fullpath instead.

Answer 3

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

root_url(:only_path => false)

Answer 4

I think request.domain would work, but what if you're in a sub directory like blah.blah.com? Something like this could work:

<%= request.env["HTTP_HOST"] + page = "/" + request.path_parameters['controller'] + "/" + request.path_parameters['action'] %>

Change the parameters based on your path structure.

Hope that helps!

Answer 5

You can use the ruby method:

:root_url

which will get the full path with base url:

localhost:3000/bla

Answer 6

In Ruby on Rails 3.1.0.rc4:

 request.fullpath
