EmailAttribute 
ActiveModel attribute serialization using the mail gem.
Usage
Assuming you have a column named address on the email_addresses table, you can easily add email address handling with:
class EmailAddresses < ActiveRecord::Base
email_address_attribute :address
end
email = EmailAddress.new({
address: "Jeff Ching <ching.jeff@gmail.com>"
})
email.address
=> "Jeff Ching <ching.jeff@gmail.com>"
email.address = "ching.jeff@gmail.com"
email.address
=> "ching.jeff@gmail.com"
email.address = "some bad email address"
email.address
=> "some bad email address"
You can also specify a column as a email address list type, which is a serialized array of email addresses.
class Email < ActiveRecord::Base
email_address_list_attribute :to
end
email = Email.new({
to: "Jeff Ching <ching.jeff@gmail.com>; email@foo.com"
})
email.to
=> "Jeff Ching <ching.jeff@gmail.com>; email@foo.com"
email.to.length
=> 2
Validating
EmailAttribute provides validation to ActiveModel. To use:
class EmailAddresses < ActiveRecord::Base
email_address_attribute :address
validates :address, email: {
allow_blank: true,
message: "is invalid"
}
end
email = EmailAddress.new({
address: "some bad email address"
})
email.save
=> false
email.errors.full_messages
=> ["Address is invalid"]
Formatting
PhonyAttribute comes built with a few named formats. You can add your own by adding to the PhonyAttribute::PhoneNumber.named_formats hash. The value can be either an options hash (passed directly to Phony's format) or a callable Proc/lambda that yields the phone number object.
