NAME

RT::CustomFieldValues::External - Pull possible values for a custom field from an arbitrary external data source.

SYNOPSIS

Custom field value lists can be produced by creating a class that inherits from RT::CustomFieldValues::External, and overloading SourceDescription and ExternalValues. See RT::CustomFieldValues::Groups for a simple example.

DESCRIPTION

Subclasses should implement the following methods:

SourceDescription

This method should return a string describing the data source; this is the identifier by which the user will see the dropdown.

ExternalValues

This method should return an array reference of hash references. The hash references must contain a key for name and can optionally contain keys for description, sortorder, and category. If supplying a category, you must also set the category the custom field is based on in the custom field configuration page.
