Rails 3 validate URL or IP address

I'm searching for a way to validate a field for correct URL or IP address in a rails model. I've played a little bit with validates :url, :format => URI::regexp(%w(http https)), and other URL validations. But how do I get the field validated with either an URL or an IP address? Maybe there is a gem for that.

thx!

Not sure if there are such gems, but custom validations can be implemented relatively simple (with ipaddress gem in the Gemfile). Try something like

require 'uri'
validate :valid_url_or_ip
...
private
def valid_url_or_ip
  unless valid_url?(url) || IPAddress.valid?(url)
    errors.add(:url, "Not an URL or IP address")
  end
end

def valid_url?
  uri = URI.parse(url)
  uri.kind_of?(URI::HTTP) || uri.kind_of?(URI::HTTPS)
rescue URI::InvalidURIError
  false
end
