    47 === Sample Config ===

     94If the `label` is not specified, it will be created by capitalizing the custom field name and replacing underscores with whitespaces.
     95
     96Macros will be expanded when rendering `textarea` fields with format `wiki`, but not when rendering `text` fields with format `wiki`.

     149=== Reports Involving Custom Fields

    84151Custom 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`.

    95 '''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.
     161'''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.

    97 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.

    116 === Updating the database ===
    117 
    118 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:
    119 
    120 {{{
    121 #!sql
    122 INSERT INTO ticket_custom
    123    (ticket, name, value)
    124    SELECT
    125       id AS ticket,
    126       'request_source' AS name,
    127       'None' AS value
    128    FROM ticket
    129    WHERE id NOT IN (
    130       SELECT ticket FROM ticket_custom
    131    );
     181Note that option names in trac.ini are case-insensitive, so even if your option name includes uppercase characters:
     182{{{#!ini
     183[ticket-custom]
     184Progress_Type = text
    132185}}}
    133 
    134 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:
    135 
    136 {{{
    137 #!sql
    138 INSERT INTO ticket_custom
    139    (ticket, name, value)
    140    SELECT
    141       id AS ticket,
    142       'request_source' AS name,
    143       'None' AS value
    144    FROM ticket
    145    WHERE id NOT IN (
    146       SELECT ticket FROM ticket_custom WHERE name = 'request_source'
    147    );
    148 }}}
     186you must use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.
