TracTicketsCustomFields
v5 v6 1 = Custom Ticket Fields 2 1 = Custom Ticket Fields = 3 2 Trac supports adding custom, user-defined fields to the ticket module. Using custom fields, you can add typed, site-specific properties to tickets. 4 3 5 == Configuration 6 4 == Configuration == 7 5 Configuring custom ticket fields is done in the [wiki:TracIni trac.ini] file. All field definitions should be under a section named `[ticket-custom]`. 8 6 … … 13 11 ... 14 12 }}} 15 16 13 The example below should help to explain the syntax. 17 14 18 === Available Field Types and Options 19 15 === Available Field Types and Options === 20 16 * '''text''': A simple (one line) text field. 21 17 * label: Descriptive label. 22 18 * value: Default value. 23 * order: Sort order placement. Determines relative placement in forms with respect to other custom fields.19 * order: Sort order placement. (Determines relative placement in forms with respect to other custom fields.) 24 20 * format: One of: 25 21 * `plain` for plain text 26 * `wiki` to interpret the content as WikiFormatting 22 * `wiki` to interpret the content as WikiFormatting (''since 0.11.3'') 27 23 * `reference` to treat the content as a queryable value (''since 1.0'') 28 24 * `list` to interpret the content as a list of queryable values, separated by whitespace (''since 1.0'') 29 25 * '''checkbox''': A boolean value check box. 30 26 * label: Descriptive label. 31 * value: Default value : 0 or 1.27 * value: Default value (0 or 1). 32 28 * order: Sort order placement. 33 29 * '''select''': Drop-down select box. Uses a list of values. … … 44 40 * label: Descriptive label. 45 41 * value: Default text. 46 * cols: Width in columns 42 * cols: Width in columns. 47 43 * rows: Height in lines. 48 44 * order: Sort order placement. 49 * format: Either `plain` for plain text or `wiki` to interpret the content as WikiFormatting. 45 * format: Either `plain` for plain text or `wiki` to interpret the content as WikiFormatting. (''since 0.11.3'') 50 46 51 Macros will be expanded when rendering `textarea` fields with format `wiki`, but not when rendering `text` fields with format `wiki`. 52 53 === Sample Configuration 54 55 {{{#!ini 47 === Sample Config === 48 {{{ 56 49 [ticket-custom] 57 50 … … 85 78 }}} 86 79 87 '' 'Note''': To make entering an option for a `select` type field optional, specify a leading `|` in the `fieldname.options` option.80 ''Note: To make entering an option for a `select` type field optional, specify a leading `|` in the `fieldname.options` option.'' 88 81 89 === Reports Involving Custom Fields 82 === Reports Involving Custom Fields === 90 83 91 84 Custom 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`. 92 85 93 {{{#!sql 86 {{{ 87 #!sql 94 88 SELECT p.value AS __color__, 95 89 id AS ticket, summary, owner, c.value AS progress … … 99 93 ORDER BY p.value 100 94 }}} 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. 101 96 102 '''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. 103 104 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: 105 {{{#!sql 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. 98 {{{ 99 #!sql 106 100 SELECT p.value AS __color__, 107 101 id AS ticket, summary, component, version, milestone, severity, … … 110 104 changetime AS _changetime, description AS _description, 111 105 reporter AS _reporter, 112 106 (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress 113 107 FROM ticket t 114 108 LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress') … … 120 114 Note in particular the `LEFT OUTER JOIN` statement here. 121 115 122 Note that if your config file uses an '''uppercase''' name: 123 {{{#!ini 124 [ticket-custom] 116 === Updating the database === 125 117 126 Progress_Type = text 127 }}} 128 you would use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`. 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: 129 119 130 === Updating the database 131 132 As noted above, any tickets created before a custom field has been defined will not have a value for that field.
