NAME

FS::part_event::Action - Base class for event actions

SYNOPSIS

package FS::part_event::Action::myaction;

use base FS::part_event::Action;

DESCRIPTION

FS::part_event::Action is a base class for event action classes.

METHODS

These methods are implemented in each action class.

description

Action classes must define a description method. This method should return a scalar description of the action.

eventtable_hashref

Action classes must define a eventtable_hashref method if they can only be triggered against some kinds of tables. This method should return a hash reference of eventtables (values set true indicate the action can be performed):

 sub eventtable_hashref {
   { 'cust_main'      => 1,
     'cust_bill'      => 1,
     'cust_pkg'       => 0,
     'cust_pay_batch' => 0,
   };
 }

event_stage

Action classes may define an event_stage method to indicate a preference for being run at a non-standard stage of the billing and collection process.

This method may currently return "collect" (the default) or "pre-bill".

option_fields

Action classes may define an option_fields method to indicate that they accept one or more options.

This method should return a list of option names and option descriptions. Each option description can be a scalar description, for simple options, or a hashref with the following values:

label - Description

; type - Currently text, money, checkbox, checkbox-multiple, select, select-agent, select-pkg_class, select-part_referral, select-table, fixed, hidden, (others can be implemented as httemplate/elements/tr-TYPE.html mason components). Defaults to text.:; size - Size for text fields:; options - For checkbox-multiple and select, a list reference of available option values.:; option_labels - For select, a hash reference of availble option values and labels.:; value - for checkbox, fixed, hidden:; table - for select-table:; name_col - for select-table:; NOTE: See httemplate/elements/select-table.html for a full list of the optinal options for the select-table type

NOTE: A database connection is not yet available when this subroutine is executed.

Example:

 sub option_fields {
   (
     'field'         => 'description',

     'another_field' => { 'label'=>'Amount', 'type'=>'money', },

     'third_field'   => { 'label'         => 'Types',
                          'type'          => 'select',
                          'options'       => [ 'h', 's' ],
                          'option_labels' => { 'h' => 'Happy',
                                               's' => 'Sad',
                                             },
   );
 }

default_weight

Action classes may define a default weighting. Weights control execution order relative to other actions (that are triggered at the same time).

deprecated

Action classes may define a deprecated method that returns true, indicating that this action is deprecated.

do_action CUSTOMER_EVENT_OBJECT

Action classes must define an action method. This method is triggered if all conditions have been met.

The object which triggered the event (an FS::cust_main, FS::cust_bill or FS::cust_pkg object) is passed as an argument.

To retreive option values, call the option method on the desired option, i.e.:

 my( $self, $cust_object ) = @_;
 $value_of_field = $self->option('field');

To indicate sucessful completion, simply return. Optionally, you can return a string of information status information about the sucessful completion, or simply return the empty string.

To indicate a failure and that this event should retry, die with the desired error message.

BASE METHODS

These methods are defined in the base class for use in action classes.

cust_main CUST_OBJECT

Return the customer object (see FS::cust_main) associated with the provided object (the object itself if it is already a customer object).

cust_pkg OBJECT

Return the package object (FS::cust_pkg) associated with the provided object. The object must be either a service (FS::svc_Common) or a package.

option_label OPTIONNAME

Returns the label for the specified option name.

option_fields_hashref

Returns the option fields as an (ordered) hash reference.

option_fields_listref

Returns just the option field names as a list reference.
