Licenses

Licenses can be used as Permit mixins, ie. Permit rules that are reused in multiple types of Permits.

Licenses have their own namespace folder license inside the app/permits folder. The default (scope less) licenses are placed directly in the license folder.

- /app
  - /permits
    - /license
      - blogging.rb
      - /admin
        - blogging.rb

Default :blogging License (scope less):

module License
  class Blogging < CanTango::License
    module Cache
      def calc_rules
        can [:create, :edit], Post
      end
    end

    module NoCache
      def calc_rules
        can :publish, Post if session[:publishing] == :on
      end
    end
  end
end

In the Blogging example, the module NoCache is used to determine the rules that apply for the :no_cache execution mode.

The :editor License applicable for the Admin scope. Typically the scope is linked to the account (but doesn't have to be).

module License::Admin
  class Blogging < CanTango::License
	  def calc_rules
	    can :edit, Post
	  end
	
	  modes :all
  end
end
