In Rails, how to get current url (but no paths)
Ruby on-RailsRubyRuby on-Rails-3Ruby on-Rails Problem Overview
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
Ruby on-Rails Solutions
Solution 1 - Ruby on-Rails
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
Solution 2 - Ruby on-Rails
request.host should do the trick, or:
request.port.blank? ? request.host : "#{request.host}: #{request.port}"
if you need to include the port too.
Solution 3 - Ruby on-Rails
Try this
<%=request.scheme + '://' + request.host_with_port%>
If you want to see all available methods on request object then
<%=request.methods.sort%>
Solution 4 - Ruby on-Rails
For protocol, domain and port
<%= "#{request.protocol + request.host}:#{request.port.to_s}" %>
Solution 5 - Ruby on-Rails
If your port could be anything other than 80 it should be included.
"#{request.protocol}#{request.host_with_port}"
Solution 6 - Ruby on-Rails
I think this can be useful too, if you're not in a controller.
URI.join(url_for(only_path: false), '/').to_s
