Module: Walruz::Subject

Defined in:
lib/walruz/subject.rb

Overview

This module provides the methods that enable a subject to register the diferent actions that can be performed to it, and associates the policies that apply to each of these actions.

Associating policies with actions on the subject.

To associate policies and actions related to a subject, we use the check_authorizations method, this will receive a Hash, where the keys are the name of the actions, and the values are the policies associated to this actions.

Example:

class Profile < ActiveRecord::Base
  include Walruz::Subject
  belongs_to :user
  check_authorizations :read   => ProfileReadPolicy,
                       :update => ProfileUpdatePolicy
end

Once the actions are registered on the subject, you can check if an actor can perform an action on it, using the Walruz::Actor methods
