/**
|
|
* Abstract base class for trackering:
|
|
* - logging all modifications of an entry
|
|
* - notifying users about changes in an entry
|
|
*
|
|
* You need to extend these class in your application:
|
|
* 1. set the required class-vars: app, id_field
|
|
* 2. optional set class-vars: creator_field, assigned_field, check2prefs
|
|
* 3. implement the required methods: get_config, get_details
|
|
* 4. optionally re-implement: get_title, get_subject, get_body, get_attachments, get_link, get_notification_link, get_message
|
|
* They are all documented in this file via phpDocumentor comments.
|
|
*
|
|
* Translate field-name to history status field:
|
|
* As history status was only char(2) prior to EGroupware 1.6, a mapping was necessary.
|
|
* Now it's varchar(64) and a mapping makes no sense for new applications, just list
|
|
* all fields to log as key AND value!
|
|
*
|
|
* History login supports now 1:N relations on a base record. To use that you need:
|
|
* - to have the 1:N relation as array of arrays with the values of that releation, eg:
|
|
* $data = array(
|
|
* 'id' => 123,
|
|
* 'title' => 'Something',
|
|
* 'date' => '2009-08-21 14:42:00',
|
|
* 'participants' => array(
|
|
* array('account_id' => 15, 'name' => 'User Hugo', 'status' => 'A', 'quantity' => 1),
|
|
* array('account_id' => 17, 'name' => 'User Bert', 'status' => 'U', 'quantity' => 3),
|
|
* ),
|
|
* );
|
|
* - set field2history as follows
|
|
* $field2history = array(
|
|
* 'id' => 'id',
|
|
* 'title' => 'title',
|
|
* 'participants' => array('uid','status','quantity'),
|
|
* );
|
|
* - set content for history log widget:
|
|
* $content['history'] = array(
|
|
* 'id' => 123,
|
|
* 'app' => 'calendar',
|
|
* 'status-widgets' => array(
|
|
* 'title' => 'label', // no need to set, as default is label
|
|
* 'date' => 'datetime',
|
|
* 'participants' = array(
|
|
* 'select-account',
|
|
* array('U' => 'Unknown', 'A' => 'Accepted', 'R' => 'Rejected'),
|
|
* 'integer',
|
|
* ),
|
|
* ),
|
|
* );
|
|
* - set lables for history:
|
|
* $sel_options['status'] = array(
|
|
* 'title' => 'Title',
|
|
* 'date' => 'Starttime',
|
|
* 'participants' => 'Participants: User, Status, Quantity', // a single label!
|
|
* );
|
|
*
|
|
* The above is also an example for using regular history login in EGroupware (by skipping the 'participants' key).
