mongoid

Mongoid (pronounced mann-goyd) is an Object-Document-Mapper (ODM) for MongoDB written in Ruby. It was conceived in August, 2009 during a whiskey-induced evening at the infamous Oasis in Florida, USA by Durran Jordan.

The philosophy of Mongoid is to provide a familiar API to Ruby developers who have been using Active Record or Data Mapper, while leveraging the power of MongoDB's schemaless and performant document-based design, dynamic queries, and atomic modifier operations.

sample syntax

*** Note that all code samples are written in Ruby 1.9 syntax.

class Artist
  include Mongoid::Document
  field :name, type: String
  embeds_many :instruments
end

class Instrument
  include Mongoid::Document
  field :name, type: String
  embedded_in :artist
end

# Find the first artist named "Syd Vicious" and create an embedded bass
# document for him. Of course he'll smash it within the next few minutes,
# but no worries we can delete it later.
Artist.where(name: "Syd Vicious").first.tap do |artist|
  artist.instruments.create(name: "Bass")
end
