    43 === Sample Config ===
     55If the `label` is not specified, it will be created by capitalizing the custom field name and replacing underscores with whitespaces.
     56
     57Macros will be expanded when rendering `textarea` fields with format `wiki`, but not when rendering `text` fields with format `wiki`.

    80111Custom 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`.

    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.

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.

    112 === Updating the database ===
     143Note that if your config file uses an uppercase name, e.g.,
     144{{{
     145[ticket-custom]
     146
     147Progress_Type = text
     148}}}
     149you would use lowercase in the SQL: `AND c.name = 'progress_type'`

     151=== Updating the database
    113152
    114153As 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:
