validate_as_email

Validate as Email

Validation of email addresses via the excellent Mail gem that is available in all Rails 3 and 4 applications.

Installation

Add this line to your application's Gemfile:

gem 'validate_as_email'

And then execute:

$ bundle

Or install it yourself as:

$ gem install validate_as_email

Usage

This gem is tested against MRI, JRuby, and Rubinius using Travis CI.

You will need to be using Rails 3 or greater to make use of this validator, as it is built on top of ActiveModel, which was introduced in Rails 3.

Usage with ActiveModel

class Person
  include ActiveModel::Validations
  validates_as_email :email
  attr_accessor :email
end

# OR

class Person
  include ActiveModel::Validations
  validates :email, email: true
  attr_accessor :email
end

Usage with ActiveRecord

class Person < ActiveRecord::Base
  validates_as_email :email
  attr_accessor :email
end

# OR

class Person < ActiveRecord::Base
  validates :email, email: true
  attr_accessor :email
end

Built-in RSpec Matcher

The custom matcher will be loaded automatically if RSpec is loaded first. Otherwise, you'll need to require the RSpec matcher manually using require 'validate_as_email/rspec'.

require 'validate_as_email/rspec'

class Person < ActiveRecord::Base
  validates_as_email :email
  attr_accessor :email
end

describe Person do
  it { should have_a_valid_email_address_for(:email) }
  it { should_not have_a_valid_email_address_for(:email) }
end
