v14 v15 25 25 == Changing Sort Order 26 26 27 Simple reports - ungrouped reports to be specific - can be changed to be sorted by any column simply by clicking the column header. 28 29 If a column header is a hyperlink (red), click the column you would like to sort by. Clicking the same header again reverses the order. 30 31 == Changing Report Numbering 32 33 There may be instances where you need to change the ID of the report, perhaps to organize the reports better. At present this requires changes to the trac database. The ''report'' table has the following schema: 34 * id integer PRIMARY KEY 35 * author text 36 * title text 37 * query text 38 * description text 39 Changing the ID changes the shown order and number in the ''Available Reports'' list and the report's perma-link. This is done by running something like: 40 {{{#!sql 41 UPDATE report SET id = 5 WHERE id = 3; 42 }}} 43 Keep in mind that the integrity has to be maintained, ie ID has to be unique, and you don't want to exceed the max, since that's managed by SQLite someplace. 44 45 You may also need to update or remove the report number stored in the report or query. 27 Simple reports - ungrouped reports to be specific - can be sorted by clicking the column header. 28 29 If a column header is a hyperlink (red), click the column to sort by it. Clicking the same header again reverses the sort order. 46 30 47 31 == Navigating Tickets 48 32 49 Clicking on one of the report results will take you to that ticket. You can navigate through the results by clicking the ''Next Ticket'' or ''Previous Ticket'' links just below the main menu bar, or click the ''Back to Report'' link to return to the report page.50 51 You can safely edit any of the tickets and continue to navigate through the results using the ''!Next/Previous/Back to Report'' links after saving your results, but when you return to the report, there will be no hint about what has changed, as would happen if you were navigating a list of tickets obtained from a query(see TracQuery#NavigatingTickets).52 53 == Alternat ive Download Formats54 55 Aside from the default HTML view, reports can also be exported in a number of alternative formats.33 Clicking on one of the report results will take you to that ticket. You can navigate through the results by clicking the ''Next Ticket'' or ''Previous Ticket'' contextual navigation links, or click the ''Back to Report'' link to return to the report page. 34 35 You can safely edit any of the tickets and continue to navigate through the results using the ''!Next/Previous/Back to Report'' links after saving your results, but when you return to the report, there will be no hint about what has changed, in contrast to the query results (see TracQuery#NavigatingTickets). 36 37 == Alternate Download Formats 38 39 In addition to the HTML view, reports can also be exported in a number of alternate formats. 56 40 At the bottom of the report page, you will find a list of available data formats. Click the desired link to 57 download the alternat ive reportformat.41 download the alternate format. 58 42 59 43 === Comma-delimited - CSV (Comma Separated Values) … … 74 58 Creating a custom report requires a comfortable knowledge of SQL. 75 59 76 Note that you need to set up[TracPermissions#Reports permissions] in order to see the buttons for adding or editing reports.60 Note that you need grant [TracPermissions#Reports permissions] in order to see the buttons for adding or editing reports. 77 61 78 62 A report is basically a single named SQL query, executed and presented by Trac. Reports can be viewed and created from a custom SQL expression directly in the web interface. … … 111 95 }}} 112 96 113 Dynamic variables can also be used in the report title and description (since 1.1.1).114 115 97 == Advanced Reports: Dynamic Variables 116 98 117 99 For more flexible reports, Trac supports the use of ''dynamic variables'' in report SQL statements. 118 In short, dynamic variables are ''special'' strings that are replaced by custom data before query execution. 100 In short, dynamic variables are ''special'' strings that are replaced by custom data before query execution. Dynamic variables can also be used in the report title and description //(since 1.1.1)//. 119 101 120 102 === Using Variables in a Query … … 154 136 === Special Columns 155 137 156 To format reports, TracReports look sfor 'magic' column names in the query result. These 'magic' names are processed and affect the layout and style of the final report.138 To format reports, TracReports look for 'magic' column names in the query result.

The URL is taken from the first row of each group. 183 165 * '''`__color__`''' — Should be a numeric value ranging from 1 to 5 to select a pre-defined row color. Typically used to color rows by issue priority. 184 {{{ 185 #!html 186 <div style="margin-left:7.5em">Defaults: 166 {{{#!html 167 <div style="margin-left:3em">Defaults: 187 168 <span style="border: none; color: #333; background: transparent; font-size: 85%; background: #fdc; border-color: #e88; color: #a22">Color 1</span> 188 169 <span style="border: none; color: #333; background: transparent; font-size: 85%; background: #ffb; border-color: #eea; color: #880">Color 2</span> … … 195 176 * '''`__class__`''' — Zero or more space-separated CSS class names to be set on the `<tr>` element of the current row. These classes are added to the class name derived from `__color__` and the odd / even indicator. 196 177 197 '''Example:''' ''List active tickets, grouped by milestone, group header linked to milestone page, colored by priority''178 '''Example:''' List active tickets, grouped by milestone, group header linked to milestone page, colored by priority: 198 179 {{{#!sql 199 180 SELECT p.value AS __color__, … … 208 189 }}} 209 190 210 '''Note:''' Atable join is used to match ''ticket'' priorities with their numeric representation from the ''enum'' table.191 Note that table join is used to match ''ticket'' priorities with their numeric representation from the ''enum'' table. 211 192 212 193 === Changing layout of report rows === #column-syntax … … 221 202 This can be used to hide any kind of column, even important ones required for identifying the resource, e.g. `id as _id` will hide the '''Id''' column but the link to the ticket will be present. 222 203 223 '''Example:''' ''List active tickets, grouped by milestone, colored by priority, with description and multi-line layout''204 '''Example:''' List active tickets, grouped by milestone, colored by priority, with description and multi-line layout: 224 205 225 206 {{{#!sql … … 242 223 === Reporting on custom fields 243 224 244 If you have added custom fields to your tickets (see TracTicketsCustomFields), you can write a SQL query to cover them. You'll need to make a join on the ticket_custom table, but this isn't especially easy.245 246 If you have tickets in the database ''before'' you declare the extra fields in trac.ini, there will be no associated data in the ticket_custom table. To get around this, use SQL's "LEFT OUTER JOIN"clauses. See [trac:TracIniReportCustomFieldSample TracIniReportCustomFieldSample] for some examples.225 If you have added [TracTicketsCustomFields custom fields] to your tickets, you can write a SQL query to include them in a report. You'll need to make a join on the `ticket_custom` table. 226 227 If you have tickets in the database ''before'' you declare the extra fields in trac.ini, there will be no associated data in the `ticket_custom` table. To get around this, use SQL's `LEFT OUTER JOIN` clauses. See [trac:TracIniReportCustomFieldSample TracIniReportCustomFieldSample] for some examples. 247 228 248 229 === A note about SQL rewriting #rewriting 249 230 250 231 Beyond the relatively trivial replacement of dynamic variables, the SQL query is also altered in order to support two features of the reports: 251 1. [#sort-order changing the sort order]252 1. pagination support (limitation of the number of result rows displayed on each page)232 1. [#sort-order sorting] 233 1. pagination: limiting the number of results displayed on each page 253 234 In order to support the first feature, the sort column is inserted in the `ORDER BY` clause in the first position or in the second position if a `__group__` column is specified (an `ORDER BY` clause is created if needed). In order to support pagination, a `LIMIT ... OFFSET ...` clause is appended. 254 235 The query might be too complex for the automatic rewrite to work correctly, resulting in an erroneous query. In this case you still have the possibility to control exactly how the rewrite is done by manually inserting the following tokens: … … 309 290 }}} 310 291 292 == Changing Report Numbering 293 294 There may be instances where you need to change the ID of the report, perhaps to organize the reports better.
