Overview

This class is abstract.

Subclass and add attr_readers for domain attributes.

Abstract base class for domain models.

Provides common initialization from hash attributes. All models are immutable - only getters, no setters.

Subclasses store domain data and contain domain logic, but do not fetch data themselves (that's the Repository's job).

Examples:

Implementing a model

class Vm < Base
  attr_reader :vmid, :name, :status

  def initialize(attributes = {})
    super
    @vmid = attributes[:vmid]
    @name = attributes[:name]
    @status = attributes[:status]
  end

  def running?
    status == "running"
  end
end
