39 An FS::part_event object represents an event definition - a billing, collection
40 or other callback which is triggered when certain customer, invoice, package or
41 other conditions are met. FS::part_event inherits from FS::Record. The
42 following fields are currently supported:
46 =item eventpart - primary key
48 =item agentnum - Optional agentnum (see L<FS::agent>)
50 =item event - event name
52 =item eventtable - table name against which this event is triggered: one of "cust_main", "cust_bill", "cust_statement", "cust_pkg", "svc_acct".
54 =item check_freq - how often events of this type are checked; currently "1d" (daily) and "1m" (monthly) are recognized. Note that the apprioriate freeside-daily and/or freeside-monthly cron job needs to be in place.
56 =item weight - ordering for events
58 =item action - event action (like part_bill_event.plan - eventcode plan)
60 =item disabled - Disabled flag, empty or `Y'
70 Creates a new invoice event definition. To add the invoice event definition to
71 the database, see L<"insert">.
73 Note that this stores the hash reference, not a distinct copy of the hash it
74 points to. You can ask the object for a copy with the I<hash> method.
78 # the new method can be inherited from FS::Record, if a table method is defined
80 sub table { 'part_event'; }
82 =item insert [ HASHREF ]
84 Adds this record to the database. If there is an error, returns the error,
85 otherwise returns false.
87 If a list or hash reference of options is supplied, part_export_option records
88 are created (see L<FS::part_event_option>).
92 # the insert method can be inherited from FS::Record
96 Delete this record from the database.
100 # the delete method can be inherited from FS::Record
102 =item replace OLD_RECORD [ HASHREF | OPTION => VALUE ... ]
104 Replaces the OLD_RECORD with this one in the database. If there is an error,
105 returns the error, otherwise returns false.
107 If a list or hash reference of options is supplied, part_event_option
108 records are created or modified (see L<FS::part_event_option>).
112 # the replace method can be inherited from FS::Record
116 Checks all fields to make sure this is a valid invoice event definition. If
117 there is an error, returns the error, otherwise returns false. Called by the
118 insert and replace methods.

305 =item initialize PARAMS
307 Identify all objects eligible for this event and create L<FS::cust_event>
308 records for each of them, as of the present time, with status "initial". When
309 combined with conditions that prevent an event from running more than once
310 (at all or within some period), this will exclude any objects that met the
311 conditions before the event was created.
313 If an L<FS::part_event> object needs to be initialized, it should be created
314 in a disabled state to avoid running the event prematurely for any existing
315 objects. C<initialize> will enable it once all the cust_event records
318 This may take some time, so it should be run from the job queue.

508 =head1 ADDING NEW EVENTTABLES
510 To add an eventtable, you must:
514 =item Add the table to "eventtable_labels" (with a label) and to
515 "eventtable_pkey" (with its primary key).
517 =item If the table doesn't have a "custnum" field of its own (such
518 as a svc_x table), add a suitable join expression to
519 eventtables_cust_join and an expression for the final custnum field
520 to eventtables_custnum.
522 =item Create a method named FS::cust_main->$eventtable(): a wrapper
523 around qsearch() to return all records in the new table belonging to
524 the cust_main object. This method must accept 'addl_from' and
525 'extra_sql' arguments in the way qsearch() does. For svc_ tables,
526 wrap the svc_x() method.
528 =item Add it to FS::cust_event->join_sql and search_sql_where so that
529 search/cust_event.html will find it.
531 =item Create a UI link/form to search for events linked to objects
532 in the new eventtable, using search/cust_event.html. Place this
533 somewhere appropriate to the eventtable.
537 See L<FS::part_event::Action> for more information.
