validates_email is a Rails 3 plugin that validates email addresses against RFC 2822 and RFC 3696
rails plugin install git://github.com/spectator/validates_email.git
or
gem 'spectator-validates_email', :require => 'validates_email'
class User < ActiveRecord::Base validates :primary_email, :email => true end
As well as any other Rails 3 validation this one has the same triggers, such as :on
, :if
, :unless
, :allow_blank
, and :allow_nil
.
Also, you can pass your own custom error message.
class User < ActiveRecord::Base validates :primary_email, :email => { :message => 'is not an email address' } end
If you like to check MX Records for email, you can use :mx
option.
class User < ActiveRecord::Base validates :primary_email, :email => { :mx => true } end
And if you like to check MX Records with fallback to A record, use :a_fallback
option.
class User < ActiveRecord::Base validates :primary_email, :email => { :mx => { :a_fallback => true } } end
If you don’t specify your own error message, then ActiveRecord’s :invalid
error message will be used to show the error.
If do check MX Records, then you have to specify your own error message or add it to your traslations:
activerecord: errors: messages: mx_invalid: "is not valid"
Most of the code were taken from Alex Dunae (dunae.ca) plugin (see github.com/alexdunae/validates_email_format_of/) and adopted for Rails 3, so pass all beers to him.
