CustomValidations

CustomValidatons is a Rails 3 gem that provides a series of custom validations. The following validations are available:

• validates_email_of
• validates_url_of
• validates_br_cnpj_of
• validates_br_cpf_of
• validates_br_postal_code_of

Add this line to your application's Gemfile:

gem 'custom_validations'

And then execute:

bundle

Or install it yourself as:

gem install custom_validations

You can use CustomValidations in any class that includes ActiveModel::Validations. See an example below on how to use it with an ActiveRecord class:

class DummyClass < ActiveRecord::Base

  validates :contact_email, email: true
  #validates_email_of :contact_email # use it the way you want

  validates :cpf,       br_cpf: true
  validates :cnpj,      br_cnpj: true
  validates :cep,       br_postal_code: true
  validates :url,       url: true
  validates :hostname,  url: { as_host: true }

end

You can customize the error messages for each validation. See https://github.com/kauplus/custom_validations/blob/master/lib/custom_validations/locale/en.yml.

Example:

"pt-BR":
  errors:
    messages:
      br_cpf: "não é um CPF válido"
      br_cnpj: "não é um CNPJ válido"
      br_postal_code: "não é um CEP válido"
      email: "não é um endereço de email"
      url: "é uma url inválida"
      url_as_host: "é uma url inválida (informe apenas o domínio, sem http e /)"

All the custom validations are automatically available via javascript for you when using https://github.com/bcardarella/client_side_validations.

In your app/assets/javascripts/application.js:

//= require rails.validations
//= require rails.custom_validations
