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

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

The `request.request_uri` only returns the **relative** URL.

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!

(url_for(:only_path => false) == "/" )? root_url : url_for(:only_path => false)

If by relative, you mean just without the domain, then look into `request.domain`.

I think that the Ruby on Rails 3.0 method is now `request.fullpath`.

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

Using #request_uri is deprecated. Use fullpath instead.

In Ruby on Rails 3.1.0.rc4:

request.fullpath

For Ruby on Rails 3:

request.url
request.host_with_port

I fired up a debugger session and queried the request object:

request.public_methods

I needed the application [URL][1] but with the subdirectory. I used:

root_url(:only_path => false)

url_for(params)

And you can easily add some new parameter:

url_for(params.merge(:tag => "lol"))
