    43 === Sample Config ===
    44 {{{
     59If the `label` is not specified, it will be created by capitalizing the custom field name and replacing underscores with whitespaces.
     60
     61Macros will be expanded when rendering `textarea` fields with format `wiki`, but not when rendering `text` fields with format `wiki`.

     114=== Reports Involving Custom Fields

    80116Custom 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`.

    83 #!sql
     118{{{#!sql
    84119SELECT p.value AS __color__,
    85120   id AS ticket, summary, owner, c.value AS progress

    90125}}}
    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.
     126'''Note''': This will only show tickets that have progress set in them. This is '''not the same as showing all tickets'''.

If you go back and modify those tickets, the field will be defined, and they will appear in the query.

    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.

    110144Note in particular the `LEFT OUTER JOIN` statement here.

    112 === Updating the database ===
    113 
    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    );
     146Note that option names in trac.ini are case-insensitive, so even if your option name includes uppercase characters:
     147{{{#!ini
     148[ticket-custom]
     149Progress_Type = text
    128150}}}
    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 }}}
     151you must use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.
