AccessPolicyRails

Rails extension for AccessPolicy. Stores the policy_check_user (default current_user) in a RequestLocalStorage. So it is not needed to pass the user around.

Further more some macros are provided to query permissions and protect actions.

Installation

Add this line to your application's Gemfile:

gem 'access_policy_rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install access_policy_rails

Usage

  class DummyController < ActionController::Base
    # ... typical controller stuff

    # instead of
    #
    # def create
    # end
    #
    # def show
    # end

    guarded_action :create do

    end

    guarded_action :show do

    end
  end


  DummyControllerPolicy = Struct.new(:current_user, :controller) do
      def create?
        !! (current_user && current_user.create_allowed?)
      end

      def show?
        !! (current_user && current_user.show_allowed?)
      end
   end

  # Query permissions in controller or view

  policy_for(an_object).allow?(:create)
