In Rails, how to get current url (but no paths)

Question

If I'm in a URL such as

http://domain.com/mysite/bla 

How can I request just the URL with no paths? Such as

http://domain.com  

Answer 1

request.host should do the trick, or:

request.port.blank? ? request.host : "#{request.host}: #{request.port}" 

if you need to include the port too.

Answer 2

You can use this

<%= request.protocol + request.host_with_port %> #=> https://domain.com:3000 <%= request.protocol + request.host %> #=> https://domain.com 

Starting from Rails 3.2 you can also use

<%= request.base_url %> #=> https://domain.com:3000
