Instance Method Details

#format_url(attribute) ⇒ Object

To format and validate a URL attribute, call format_url in any Active Record model class and pass it the name of an attribute.

class User < ActiveRecord::Base
  format_url :website
end

This will add a before_validation callback to add “http://” to the attribute if a protocol doesn’t exist already. It then validates the format of the URL.
