    23Trac supports adding custom, user-defined fields to the ticket module. Using custom fields, you can add typed, site-specific properties to tickets.

    57Configuring custom ticket fields is done in the [wiki:TracIni trac.ini] file. All field definitions should be under a section named `[ticket-custom]`.

    8091Custom 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`.

     93{{{#!sql
    8494SELECT p.value AS __color__,

    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.
    92101
    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.

     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.

     104However, 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
    96106SELECT p.value AS __color__,
    97107   id AS ticket, summary, component, version, milestone, severity,

    101111   reporter AS _reporter,

     112   (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
    103113  FROM ticket t
    104114     LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress')
     
    110120Note in particular the `LEFT OUTER JOIN` statement here.

    112 === Updating the database ===
     122Note that if your config file uses an '''uppercase''' name:
     123{{{#!ini
     124[ticket-custom]
    113125
    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:
     126Progress_Type = text
     127}}}
     128you would use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.

    130147If 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:
