Trac supports adding custom, user-defined fields to the ticket module. Using custom fields, you can add typed, site-specific properties to tickets.
Configuring custom ticket fields is done in the trac.ini file. All field definitions should be under a section named `ticket-custom`.
The syntax of each field definition is:
FIELD_NAME = TYPE (FIELD_NAME.OPTION = VALUE) ...
The example below should help to explain the syntax.
[[:ticket-custom]] test_one = text test_one.label = Just a text box test_two = text test_two.label = Another text-box test_two.value = Just a default value test_three = checkbox test_three.label = Some checkbox test_three.value = 1 test_four = select test_four.label = My selectbox test_four.options = one|two|third option|four test_four.value = 2 test_five = radio test_five.label = Radio buttons are fun test_five.options = uno|dos|tres|cuatro|cinco test_five.value = 1 test_six = textarea test_six.label = This is a large textarea test_six.value = Default text test_six.cols = 60 test_six.rows = 30
Note: To make entering an option for a `select` type field optional, specify a leading `|` in the `fieldname.options` option.
The SQL required for TracReports to include custom ticket fields is relatively hard to get right. You need a `JOIN` with the `ticket_custom` field for every custom field that should be involved.
The following example includes a custom ticket field named `progress` in the report:
#!sql SELECT p.value AS __color__, id AS ticket, summary, component, version, milestone, severity, (CASE status WHEN 'assigned' THEN owner|' *' ELSE owner END) AS owner, time AS created, changetime AS _changetime, description AS _description, reporter AS _reporter, (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress FROM ticket t LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress') JOIN enum p ON p.name = t.priority AND p.type='priority' WHERE status IN ('new', 'assigned', 'reopened') ORDER BY p.value, milestone, severity, time
Note in particular the `LEFT OUTER JOIN` statement here.
