Module: JSS::Categorizable

Included in:
MobileDeviceApplication, Package, Policy, Script
Defined in:
lib/jss/api_object/categorizable.rb,
lib/jss.rb

Overview

A mix-in module that centralizes the code for handling objects which can be assigned a ‘category’ in the JSS.

Objects in the JSS present category data in two different ways:

1) An ‘old’ style, where the top-level Hash of the API data contains a

:category which contains a String, being the category name.

2) A ‘new’ style, where the top-level :general Hash contains a :category key

which is a Hash with a :name and :id key.

This module can detect and handle either type.

Classes mixing in this module MUST:

  • call #add_category_to_xml(xmldoc) from their #rest_xml method if they are Updatable or Creatable
