# AddressableUrlValidator
|
|
#
|
|
# Custom validator for URLs. This is a stricter version of UrlValidator - it also checks
|
|
# for using the right protocol, but it actually parses the URL checking for any syntax errors.
|
|
# The regex is also different from `URI` as we use `Addressable::URI` here.
|
|
#
|
|
# By default, only URLs for http, https, ssh, and git protocols will be considered valid.
|
|
# Provide a `:protocols` option to configure accepted protocols.
|
|
#
|
|
# Example:
|
|
#
|
|
# class User < ActiveRecord::Base
|
|
# validates :personal_url, addressable_url: true
|
|
#
|
|
# validates :ftp_url, addressable_url: { protocols: %w(ftp) }
|
|
#
|
|
# validates :git_url, addressable_url: { protocols: %w(http https ssh git) }
|
|
# end
|
|
#
|
|
class AddressableUrlValidator < ActiveModel::EachValidator
