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

    43 === Sample Config ===
    44 {{{
     93If the `label` is not specified, it will be created by capitalizing the custom field name and replacing underscores with whitespaces.
     94
     95Macros will be expanded when rendering `textarea` fields with format `wiki`, but not when rendering `text` fields with format `wiki`.

     148=== Reports Involving Custom Fields
    79149
    80150Custom 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`.
    81151
    82 {{{
    83 #!sql
     152{{{#!sql
    84153SELECT p.value AS __color__,
    85154   id AS ticket, summary, owner, c.value AS progress
    … …  
    89158  ORDER BY p.value
    90159}}}
    91 '''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.
     160'''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.
    92161
    93 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.

     162However, 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:
     163{{{#!sql
    96164SELECT p.value AS __color__,
    97165   id AS ticket, summary, component, version, milestone, severity,
    … …

    101169   reporter AS _reporter,
    102   (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
     170   (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
    103171  FROM ticket t
    104172     LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress')
    … …  
    110178Note in particular the `LEFT OUTER JOIN` statement here.
    111179
    112 === Updating the database ===
     180Note that if your config file uses an '''uppercase''' name:
     181{{{#!ini
     182[ticket-custom]
    113183
    114 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:
    115 
    116 {{{
    117 #!sql
    118 INSERT INTO ticket_custom
    119    (ticket, name, value)
    120    SELECT
    121       id AS ticket,
    122       'request_source' AS name,
    123       'None' AS value
    124    FROM ticket
    125    WHERE id NOT IN (
    126       SELECT ticket FROM ticket_custom
    127    );
     184Progress_Type = text
    128185}}}
    129 
    130 If 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:
    131 
    132 {{{
    133 #!sql
    134 INSERT INTO ticket_custom
    135    (ticket, name, value)
    136    SELECT
    137       id AS ticket,
    138       'request_source' AS name,
    139       'None' AS value
    140    FROM ticket
    141    WHERE id NOT IN (
    142       SELECT ticket FROM ticket_custom WHERE name = 'request_source'
    143    );
    144 }}}
     186you would use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.
