== Cassandra Object

Cassandra Object uses ActiveModel to mimic much of the behavior in ActiveRecord.


== Defining Models

  class Widget < CassandraObject::Base
    key :uuid
    attribute :name, type: :string
    attribute :description, type: :string
    attribute :price, type: :integer

    validates :name, presence: :true

    before_create do
      self.description = "#{name} is the best product ever"
    end
  end

== Creating and updating records

Cassandra Object has equivalent methods as ActiveRecord:

  widget = Widget.new
  widget.valid?
  widget = Widget.create(name: 'Acme', price: 100)
  widget.update_attribute(:price, 1200)
  widget.update_attributes(price: 1200, name: 'Acme Corporation')
  widget.attributes = {price: 300}
  widget.price_was
  widget.save
  widget.save!

== Finding records

  widget = Widget.find(uuid)
  widget = Widget.first
  widgets = Widget.all
  Widget.find_each do |widget|
    ...
  end
