    44== Configuration

    56Configuring custom ticket fields is done in the [wiki:TracIni trac.ini] file. All field definitions should be under a section named `[ticket-custom]`.

    1315The example below should help to explain the syntax.

    1517=== Available Field Types and Options
     18
    1619 * '''text''': A simple (one line) text field.
    1720   * label: Descriptive label.
     
    5760Macros will be expanded when rendering `textarea` fields with format `wiki`, but not when rendering `text` fields with format `wiki`.

    111115Custom ticket fields are stored in the `ticket_custom` table, not in the `ticket` table. 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`.
    112116
    113 {{{
    114 #!sql
     117{{{#!sql
    115118SELECT p.value AS __color__,
    116119   id AS ticket, summary, owner, c.value AS progress
     
    123126
    124127However, 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
     128{{{#!sql
    127129SELECT p.value AS __color__,
    128130   id AS ticket, summary, component, version, milestone, severity,
     
    131133   changetime AS _changetime, description AS _description,
    132134   reporter AS _reporter,
    133   (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
     135   (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
    134136  FROM ticket t
    135137     LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress')
     
    141143Note in particular the `LEFT OUTER JOIN` statement here.
    142144
    143 Note that if your config file uses an uppercase name, e.g.,
    144 {{{
     145Note that if your config file uses an '''uppercase''' name:
     146{{{#!ini
    145147[ticket-custom]
    146148
    147149Progress_Type = text
    148150}}}
    149 you would use lowercase in the SQL: `AND c.name = 'progress_type'`
     151you would use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.
    150152
    151153=== Updating the database
    152154
    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:

    169170If you added multiple custom fields at different points in time, you should be more specific in the subquery on table {{{ticket}}} by adding the exact custom field name to the query:
