You can get it your controller through

request.request\_uri

or in your view through

controller.request.request\_uri

All the CGI-style variables are available through request.env as well,  
so this works:

request.env[‘REQUEST\_URI’]

But I wonder why you want it? You normally work with the Rails routing  
system and don’t deal with the details of the request URI. What are  
you trying to accomplish?

Many thanks for the fast reply.

The request.env[‘REQUEST\_URI’] only returns the path eg:  
[http://localhost:3000/user](http://localhost:3000/user) I get /user . Iactually want  
[http://localhost:3000/](http://localhost:3000/)  
I can do this via request.protocol()+request.request\_uri() but I  
wonder if there is a single method that can do this.

I need this for mail sending. I’m creating a user activation system  
that wan run on multiple domains. When I send out a mail the user has  
to click alink to activate it. Ofcourse this link is dependant on the  
domain the site is hosted on.

Use url\_for with :only\_path set to false to generate full url’s

activate\_link = url\_for({:only\_path =\> false}, :controller =\>  
‘account’, :action =\> ‘activate’, :id =\> @user)

Or, if you have a named route for activation, these generate full  
url’s by default:

activate\_link = activate\_url(:id =\> @user)
