Get the real IP address of client with Rails and Nginx?

ruby-on-rails web-services networking nginx ip-address

Rails was supposed to be doing it automatically for us, but it seems to be broken with current 3.x

I'm using this:

def ip() request.env['HTTP_X_FORWARDED_FOR'] || request.remote_ip end

ruby-on-rails web-services networking nginx ip-address

You should get the header value X-forwarded-for
