How to send paperclip file to ftp?

Question

Ruby on Rails

I'm using the gem https://github.com/xing/paperclip-storage-ftp But I can't figure out what I'm doing wrong - why the url is wrong (each /images/original/missing.png entry has it). My settings

has_attached_file :image, {
    :storage => :ftp,

    :path => '/ftp/menu-images/:filename',

    :url => "http://site.com/ftp/menu-images/:filename",
    :ftp_servers => [
      {
        :host     => 'ip',
        :user     => 'username',
        :password => 'pass'
      },
    ],
    passive: true
  }

public/ftp/menu-images/ directory created in my rails app And I did mount --bind /home/ftp/menu-images/ /www/var/www/apps/app/current/public/ftp Files appear on disk - but the url of the entries is wrong.
Thanks to all
