Using custom fields, you can add typed, site-specific properties to tickets. 3 4 4 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 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 ; this determines relative placement in forms with respect to other custom fields.23 * 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`. 112 92 113 {{{ 114 #!sql 93 {{{#!sql 115 94 SELECT p.value AS __color__, 116 95 id AS ticket, summary, owner, c.value AS progress … … 120 99 ORDER BY p.value 121 100 }}} 122 '''Note''': This will only show tickets that have progress set in them. This 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. 101 102 '''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. 123 103 124 104 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: 125 {{{ 126 #!sql 105 {{{#!sql 127 106 SELECT p.value AS __color__, 128 107 id AS ticket, summary, component, version, milestone, severity, … … 131 110 changetime AS _changetime, description AS _description, 132 111 reporter AS _reporter, 133 (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 134 113 FROM ticket t 135 114 LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress') … … 141 120 Note in particular the `LEFT OUTER JOIN` statement here. 142 121 143 Note that if your config file uses an uppercase name, e.g.,144 {{{ 122 Note that if your config file uses an '''uppercase''' name: 123 {{{#!ini 145 124 [ticket-custom] 146 125 147 126 Progress_Type = text 148 127 }}} 149 you would use lowercase in the SQL: `AND c.name = 'progress_type'`128 you would use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`. 150 129 151 130 === Updating the database 152 131 153 As noted above, any tickets created before a custom field has been defined will not have a value for that field. Here 's a bit of SQL (tested with SQLite) that you can run directly on the Trac database to set an initial value for custom ticket fields. Inserts the default value of 'None' into a custom field called 'request_source' for all tickets that have no existing value:132 As noted above, any tickets created before a custom field has been defined will not have a value for that field.
