email_validator ActiveModel::EachValidator¶ ↑

Validate e-mail addresses against RFC 2822 and RFC 3696.

gem 'vjt-email_validator', :git => 'git://github.com/vjt/email_validator'

Standalone:

EmailValidator.valid?(email) # => true or false

Inside an ActiveRecord model:

class Person < ActiveRecord::Base
  validates :email, :email => true
end

Giving ‘:email => true` to the `validate` method uses the following default options. Customize them using `:email => { .. }`; E.g. `:email => {:check_mx => true}`

:message
   String. A custom error message (default is: "does not appear to be a valid e-mail address")
:mx_message
   String. A custom error message displayed when there is no MX for the given e-mail address
   (default is: "is not routable")
:multiple_message
   String. A custom error message displayed when one of the e-mail addresses in the record
   is invalid (default is "appears to contain an invalid e-mail address)
:multiple
   Boolean. Allows multiple email addresses separated by space and/or comma/colon
:check_mx
   Boolean. Check domain for a valid MX record (default is false)
:local_length
  Maximum number of characters allowed in the local part (default is 64)
:domain_length
  Maximum number of characters allowed in the domain part (default is 255)

To execute the unit tests run rake test.

The unit tests for this plugin use an in-memory sqlite3 database.
