Question

I am using Mongoid for the first time. I want to store a collection of emails that have a subject, body, and arrays of to, cc, and bcc recipients. Example:

{to: [{email: '[e-mail]', name: 'Andrew'}], cc: ...

However, I can’t seem to figure out how to model this data using Mongoid. I think the term for these are called embedded documents, but everything I’ve tried does not seem to work right. How do I create my models correctly with Mongoid?

Answer 1

Here is the solution. You can specify class name if you want to reuse a class for multiple fields:

class Email
  include Mongoid::Document

  embeds_many :to_recipients, :class_name => "Recipient"
  embeds_many :cc_recipients, :class_name => "Recipient"
  embeds_many :bcc_recipients, :class_name => "Recipient"    
  embeds_one :from, :class_name => "Recipient"

  field :subject, type: String
  field :body_text, type: String
  field :body_html, type: String
end

class Recipient
  include Mongoid::Document
  field :email_address, type: String
  field :name, type: String
  validates :email_address, :presence => true
  embedded_in :emails
end
