Module: Ripple::Associations

Adds associations via links and embedding to Document models. Examples:

  # Documents can contain embedded documents, and link to other standalone documents
  # via associations using the many and one class methods.
  class Person
    include Ripple::Document
    property :name, String
    many :addresses
    many :friends, :class_name => "Person"
    one :account
  end
   
  # Account and Address are embeddable documents
  class Account
    include Ripple::EmbeddedDocument
    property :paid_until, Time
    embedded_in :person # Adds "person" method to get parent document
  end
   
  class Address
    include Ripple::EmbeddedDocument
    property :street, String
    property :city, String
    property :state, String
    property :zip, String
  end
   
  person = Person.find("adamhunter")
  person.friends << Person.find("seancribbs") # Links to people/seancribbs with tag "friend"
  person.addresses << Address.new(:street => "100 Main Street") # Adds an embedded address
  person.account.paid_until = 3.months.from_now
