Overview

About Mongoid

Mongoid is an ODM (Object-Document-Mapper) framework for MongoDB in Ruby.

Project Tracking

Mongoid on Pivotal Tracker
Mongoid Google Group
Mongoid on CI Joe

Compatibility

Mongoid is developed against Ruby 1.8.6, 1.8.7, 1.9.1, 1.9.2

Note API changes will be frequent until the 1.0 release, and do not expect the gem to be of full production quality until that point.

Mongoid in Action

Initialize Mongoid:

  Mongoid.connect_to("myapp_database_name")

Example of a simple domain model:

  class Person < Mongoid::Document
    field :title
    field :age, :default => 0
    has_many :addresses
    has_one :name
  end

  class Address < Mongoid::Document
    field :street
    field :city
    field :state
    field :post_code
    belongs_to :person
  end

  class Name < Mongoid::Document
    field :first_name
    field :last_name
    has_timestamps
  end

Mongoid supports all the basic ActiveRecord creation and persistence methods.

Creation:

  Person.create(:title => "Esquire")
  Person.create!(:title => "Sir", :name => { :first_name => "Elton", :last_name => "John" })

Save:

  person.save
  person.save!

Updating:

  person.update_attributes(:title => "Sir")
  person.update_attributes!(:name => { :first_name => "Emmanuel", :last_name => "Zorg" })

Deleting:

  person.destroy
  Person.destroy_all(:title => "Sir")
  person.delete
  Person.delete_all(:title => "Sir")

Retrieval of Documents from the database can be done in the traditional ActiveRecord
manner or done using the Mongoid criteria DSL.

Old School:

  Person.find(:all, :conditions => { :title => "Esquire" })
  Person.find(:first, :conditions => { :title => "Esquire" })
  Person.first(:conditions => { :title => "Sir" })
  Person.all(:conditions => { :title => "Sir" })

New School:

  Person.select(:first_name, :last_name).where(:title => "Sir").skip(10).limit(10).execute
  Criteria.translate(:conditions => { :title => "Sir" }).execute

Paginate Document search results:

  Person.paginate(:conditions => {:title => "Esquire"}, :page => 1, :per_page => 20)

Validations:

Mongoid supports all validations provided by Jay Fields’ Validatable gem.
