URL Formatter

Format and validate a URL attribute in Active Record. This is an example gem created for RailsCasts episode #301.

Add to your Gemfile and run the bundle command to install it.

gem "url_formatter"

Requires Ruby 1.9.2 or later.

Call format_url in an ActiveRecord class and pass the name of the attribute you wish to format into a URL and validate.

class Comment < ActiveRecord::Base
  format_url :website
end

This will automatically add "http://" to the beginning of the website attribute upon saving if no protocol is present. It will also do validation to ensure it looks like a URL.
