(Determines relative placement in forms with respect to other custom fields.)57 * order: Sort order placement; this determines relative placement in forms with respect to other custom fields. 20 58 * format: One of: 21 59 * `plain` for plain text … … 25 63 * '''checkbox''': A boolean value check box. 26 64 * label: Descriptive label. 27 * value: Default value (0 or 1).65 * value: Default value, 0 or 1. 28 66 * order: Sort order placement. 29 67 * '''select''': Drop-down select box. Uses a list of values. … … 35 73 * label: Descriptive label. 36 74 * options: List of values, separated by '''|''' (vertical pipe). 37 * value: Default value (one of the values from options).75 * value: Default value, one of the values from options. 38 76 * order: Sort order placement. 39 77 * '''textarea''': Multi-line text area. 40 78 * label: Descriptive label. 41 79 * value: Default text. 42 * cols: Width in columns 80 * cols: Width in columns. //(Removed in 1.1.2)// 43 81 * rows: Height in lines. 44 82 * order: Sort order placement. 45 83 * format: Either `plain` for plain text or `wiki` to interpret the content as WikiFormatting. 84 * '''time''': Date and time picker. (''Since 1.1.1.'') 85 * label: Descriptive label. 86 * value: Default date. 87 * order: Sort order placement. 88 * format: One of: 89 * `relative` for relative dates. 90 * `date` for absolute dates. 91 * `datetime` for absolute date and time values. 92 93 If the `label` is not specified, it will be created by capitalizing the custom field name and replacing underscores with whitespaces. 46 94 47 95 Macros will be expanded when rendering `textarea` fields with format `wiki`, but not when rendering `text` fields with format `wiki`. 48 96 49 === Sample Config === 50 {{{ 97 === Sample Configuration 98 99 {{{#!ini 51 100 [ticket-custom] 52 101 … … 78 127 test_six.cols = 60 79 128 test_six.rows = 30 129 130 test_seven = time 131 test_seven.label = A relative date 132 test_seven.format = relative 133 test_seven.value = now 134 135 test_eight = time 136 test_eight.label = An absolute date 137 test_eight.format = date 138 test_eight.value = yesterday 139 140 test_nine = time 141 test_nine.label = A date and time 142 test_nine.format = datetime 143 test_nine.value = in 2 hours 80 144 }}} 81 145 82 '' Note: To make entering an option for a `select` type field optional, specify a leading `|` in the `fieldname.options` option.''146 '''Note''': To make a `select` type field optional, specify a leading `|` in the `fieldname.options` option. 83 147 84 === Reports Involving Custom Fields ===148 === Reports Involving Custom Fields 85 149 86 150 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`. 87 151 88 {{{ 89 #!sql 152 {{{#!sql 90 153 SELECT p.value AS __color__, 91 154 id AS ticket, summary, owner, c.value AS progress … … 95 158 ORDER BY p.value 96 159 }}} 97 '''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.160 '''Note''': This will only show tickets that have progress set in them. This 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. 98 161 99 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. 100 {{{ 101 #!sql 162 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: 163 {{{#!sql 102 164 SELECT p.value AS __color__, 103 165 id AS ticket, summary, component, version, milestone, severity, … … 106 168 changetime AS _changetime, description AS _description, 107 169 reporter AS _reporter, 108 (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress170 (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress 109 171 FROM ticket t 110 172 LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress') … … 116 178 Note in particular the `LEFT OUTER JOIN` statement here. 117 179 118 Note that if your config file uses an uppercase name, e.g.,119 {{{ 180 Note that if your config file uses an '''uppercase''' name: 181 {{{#!ini 120 182 [ticket-custom] 121 183 122 184 Progress_Type = text 123 185 }}} 124 you would use lowercase in the SQL: `AND c.name = 'progress_type'` 125 126 === Updating the database === 127 128 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: 129 130 {{{ 131 #!sql 132 INSERT INTO ticket_custom 133 (ticket, name, value) 134 SELECT 135 id AS ticket, 136 'request_source' AS name, 137 'None' AS value 138 FROM ticket 139 WHERE id NOT IN ( 140 SELECT ticket FROM ticket_custom 141 ); 142 }}} 143 144 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: 145 146 {{{ 147 #!sql 148 INSERT INTO ticket_custom 149 (ticket, name, value) 150 SELECT 151 id AS ticket, 152 'request_source' AS name, 153 'None' AS value 154 FROM ticket 155 WHERE id NOT IN ( 156 SELECT ticket FROM ticket_custom WHERE name = 'request_source' 157 ); 158 }}} 186 you would use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`. 159 187 160 188 ----
