About

This gem adds a very simple URL format validator to be used with Active Record models in Rails 3.0. It supports localized error messages. It can validate many different kinds of URLs, including HTTP and HTTPS. It supports advanced validation features like sending HEAD requests to URLS to verify that they are valid endpoints.

Installation

Add the gem to your project’s Gemfile:

“uby gem ‘url_validation’

Usage

This gem is an EachValidator, and thus is used with the validates method:

“uby class User < ActiveRecord::Base validates :terms_of_service_link, presence: true, url: true end

There are other options to fine-tune your validation; see the UrlValidator class for more, and for a list of error message localization keys.
