2. MongoDB from Mongoid
MongoDB: (from "humongous") is a scalable,
high-performance, open source, document-
oriented database.
Mongoid: Mongoid (pronounced mann-goyd) is
an Object-Document-Mapper (ODM) for
MongoDB written in Ruby.

3. The philosophy of Mongoid is to provide a
familiar API to Ruby developers who have been
using Active Record or Data Mapper

#...

5. class User

field :email, :type => String
field :auto_approved, :type => Boolean
field :message, :type => String

field :email, :type => String
field :auto_approved, :type => Boolean
field :message, :type => String

embeds_many :devices
has_many :cars

9. @user = User.first
@user = User.find(params[:id])
@users = User.where(:phone => “123”)
@users = @users.any_of({name: /abc*/i})
@user = User.where({"devices.token"=>”ff”})
@user.devices.where({token: params[:t]})
Person.where(:title.all => ["Sir"])
