validates_email is a Rails 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 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 http://github.com/alexdunae/validates_email_format_of/) and adopted for Rails 3 playing around with Rails 3 beta, so pass all beers to him.
