With custom fields you can add typed, site-specific properties to tickets. 4 3 5 4 == Configuration 6 7 5 Configuring custom ticket fields is done in the [wiki:TracIni trac.ini] file.

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`. 92 112 93 {{{#!sql 113 {{{ 114 #!sql 94 115 SELECT p.value AS __color__, 95 116 id AS ticket, summary, owner, c.value AS progress … … 99 120 ORDER BY p.value 100 121 }}} 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. 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. 103 123 104 124 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 125 {{{ 126 #!sql 106 127 SELECT p.value AS __color__, 107 128 id AS ticket, summary, component, version, milestone, severity, … … 110 131 changetime AS _changetime, description AS _description, 111 132 reporter AS _reporter, 112 133 (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress 113 134 FROM ticket t 114 135 LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress') … … 120 141 Note in particular the `LEFT OUTER JOIN` statement here. 121 142 122 Note that if your config file uses an '''uppercase''' name:123 {{{ #!ini143 Note that if your config file uses an uppercase name, e.g., 144 {{{ 124 145 [ticket-custom] 125 146 126 147 Progress_Type = text 127 148 }}} 128 you would use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.149 you would use lowercase in the SQL: `AND c.name = 'progress_type'` 129 150 130 151 === Updating the database 131 152 132 As noted above, any tickets created before a custom field has been defined will not have a value for that field. Here is some SQL (tested with SQLite) that you can run directly on the Trac database to set an initial value for custom ticket fields. It inserts the default value of 'None' into a custom field called 'request_source' for all tickets that have no existing value:153 As noted above, any tickets created before a custom field has been defined will not have a value for that field.
