ActiveValidators

Collection of ActiveModel/ActiveRecord validations

Installation (Rails 3)

In your Gemfile ( >>= 1.1.0 ):

gem 'activevalidators'

N.B: if you use version <= 1.0.2, use this instead:

gem 'activevalidators', :require => 'active_validators'

In your models, the gem provides new validators like email, or url:

class User
  validates :email_address, :email => true
  validates :link_url,      :url   => true
  validates :user_phone,    :phone => true
end

class Article
  validates :slug,          :slug => true
  validates :expiration_date,
                  :date => {
                             :after => lambda { Time.now },
                             :before => lambda { Time.now + 1.year }
                           }
end

class Device
  validates :ipv6,          :ip => { :format => :v6 }
  validates :ipv4,          :ip => { :format => :v4 }
end

class Account
  validates :visa_card,     :credit_card => { :type => :visa }
  validates :credit_card,   :credit_card => { :type => :all  }
end

Exhaustive list of supported validators and their implementation:

email : based on the mail gem
url : based on a regular expression
phone : based on a regular expression
slug : based on ActiveSupport::String#parameterize
ip : based on Resolv::IPv[4|6]::Regex
credit_card : based on the Luhnacy gem
date : based on the DateValidator gem

Todo

Lots of improvements can be made:

Add I18n specific types of error messages for each validator
Implement new validators
...

Note on Patches/Pull Requests

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
