Method: MongoDoc::ReferencesMany#references_many

Defined in:
lib/mongo_doc/references_many.rb

#references_many(*args) ⇒ Object

Declare reference to an array of Documents. The references can be ObjectId references or a BSON::DBRef, but cannot be both.

Use an ObjectId reference when you have a simple reference or will be referencing a single polymorphic collection. Example:

references_many :addresses references_many :addresses, :as => :work_address+

  • classname

    name of Document type as an underscore symbol or string

  • options

    :as specifies the name of the attribute, defaults to

classname

Use a BSON::DBRef when you need a reference to multiple collections. Example:

references_many :as_ref => :work_address

  • required

    :as_ref name of the attribute
