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. (Determines relative placement in forms with respect to other custom fields.) 23 * order: Sort order placement. Determines relative placement in forms with respect to other custom fields. 24 * format: One of: 25 * `plain` for plain text 26 * `wiki` to interpret the content as WikiFormatting 27 * `reference` to treat the content as a queryable value (''since 1.0'') 28 * `list` to interpret the content as a list of queryable values, separated by whitespace (''since 1.0'') 20 29 * '''checkbox''': A boolean value check box. 21 30 * label: Descriptive label. 22 * value: Default value (0 or 1).31 * value: Default value: 0 or 1. 23 32 * order: Sort order placement. 24 33 * '''select''': Drop-down select box.

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`. 78 92 79 {{{ 80 #!sql 93 {{{#!sql 81 94 SELECT p.value AS __color__, 82 95 id AS ticket, summary, owner, c.value AS progress … … 86 99 ORDER BY p.value 87 100 }}} 88 '''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.89 101 90 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. 91 {{{ 92 #!sql 102 '''Note''': 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 is all that is required, you're set. 103 104 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: 105 {{{#!sql 93 106 SELECT p.value AS __color__, 94 107 id AS ticket, summary, component, version, milestone, severity, … … 97 110 changetime AS _changetime, description AS _description, 98 111 reporter AS _reporter, 99 (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress112 (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress 100 113 FROM ticket t 101 114 LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress') … … 107 120 Note in particular the `LEFT OUTER JOIN` statement here. 108 121 109 === Updating the database === 122 Note that if your config file uses an '''uppercase''' name: 123 {{{#!ini 124 [ticket-custom] 110 125 111 As noted above, any tickets created before a custom field has been defined will not have a value for that field.
