Overview

The parent class of ExtensionAttribute objects in the JSS.

The API extension attribute objects work with the definitions of extension attributes, not the resulting values stored in the JSS with the inventory reports.

This superclass, however, uses the AdvancedSearch subclasses to provide access to the reported values in two ways:

  • A list of target objects with a certain value for the ExtensionAttribute instance. See the #all_with_result method for details

  • A list of the most recent value for this ExtensionAttribute in all targets in the JSS

The ComputerExtensionAttribute subclass offers a ComputerExtensionAttribute#history method providing the history of values for the EA for one computer. This requires MySQL access to the JSS database since that history isn’t available via the API.

Subclasses of ExtensionAttribute must define these constants:

Instance Method Details

#all_with_result(search_type, desired_value) ⇒ Array<Hash{:id=>Integer,:name=>String,:value=>String,Integer,Time}>

Get an Array of Hashes for all inventory objects with a desired result in their latest report for this EA.

Each Hash is one inventory object (computer, mobile device, user), with these keys:

:id - the computer id
:name - the computer name
:value - the matching ext attr value for the objects latest report.

This is done by creating a temprary AdvancedSearch for objects with matching values in the EA field, then getting the #search_results hash from it.

The AdvancedSearch is then deleted.

must be a member of Jamf::Criterion::SEARCH_TYPES

Parameters:

  • search_type (String) —

    how are we comparing the stored value with the desired value.

  • desired_value (String) —

    the value to compare with the stored value to determine a match.

Returns:

#latest_values ⇒ Array<Hash{:id=>Integer,:name=>String,:value=>String,Integer,Time,:as_of=>Time}>

for this EA on all inventory objects in the JSS.

Each Hash is one inventory object (computer, mobile device, user), with these keys:

:id - the jss id
:name - the object (computer, user, mobiledevice) name
:value - the most recent ext attr value for the object.
:as_of - the timestamp of when the value was collected (nil for User EAs, or for devices that have never collected inventory)
:username - the username associated with the object

This is done by creating a temporary AdvancedSearch for all objects, with the EA as a display field. The #search_result then contains the desired data.

The AdvancedSearch is then deleted.

Returns:
