TracTicketsCustomFields

Using custom fields, you can add typed, site-specific properties to tickets. 3 4 4 == Configuration == 5 == Configuration 6 5 7 Configuring custom ticket fields is done in the [wiki:TracIni trac.ini] file. All field definitions should be under a section named `[ticket-custom]`. 6 8 … … 11 13 ... 12 14 }}} 15 13 16 The example below should help to explain the syntax. 14 17 15 === Available Field Types and Options === 18 === Available Field Types and Options 19 16 20 * '''text''': A simple (one line) text field. 17 21 * label: Descriptive label. 18 22 * value: Default value. 19 * order: Sort order placement.

So to display the values from custom fields in a report, you will need a join on the 2 tables. Let's use an example with a custom ticket field called `progress`. 87 92 88 {{{ 89 #!sql 93 {{{#!sql 90 94 SELECT p.value AS __color__, 91 95 id AS ticket, summary, owner, c.value AS progress … … 95 99 ORDER BY p.value 96 100 }}} 97 '''Note''' that this will only show tickets that have progress set in them, which is '''not the same as showing all tickets'''. If you created this custom ticket field ''after'' you have already created some tickets, they will not have that field defined, and thus they will never show up on this ticket query. If you go back and modify those tickets, the field will be defined, and they will appear in the query. If that's all you want, you're set.98 101 99 However, if you want to show all ticket entries (with progress defined and without), you need to use a `JOIN` for every custom field that is in the query. 100 {{{ 101 #!sql 102 '''Note''': This will only show tickets that have progress set in them, which is '''not the same as showing all tickets'''.
