I have an IncomingEmail model with an attachments virtual attribute:
class IncomingEmail < ActiveRecord::Base
attr_accessor :attachments
end
I want the attachments virtual attribute to be initialized to [] rather than nil so that I can do:
>> i = IncomingEmail.new
=> #<IncomingEmail id: nil,...)
>> i.attachments << "whatever"
Without first setting i.attachments to [] (put another way, I want this virtual attribute to default to an empty array rather than nil)
