The Trac reports module provides a simple, yet powerful reporting facility to present information about tickets in the Trac database.
Rather than have its own report definition format, TracReports relies on standard SQL SELECT statements for custom report definition.
A report consists of these basic parts:
Simple reports - ungrouped reports to be specific - can be changed to be sorted by any column simply by clicking the column header.
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.
Aside from the default HTML view, reports can also be exported in a number of alternative formats. At the bottom of the report page, you will find a list of available data formats. Click the desired link to download the alternative report format.
Export the report as plain text, each row on its own line, columns separated by a single comma (','). Note: Carriage returns, line feeds, and commas are stripped from column data to preserve the CSV structure.
Like above, but uses tabs (\t) instead of comma.
All reports support syndication using XML/RSS 2.0. To subscribe to an RSS feed, click the orange 'XML' icon at the bottom of the page. See TracRss for general information on RSS support in Trac.
Creating a custom report requires a comfortable knowledge of SQL.
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 from the web interface.
Typically, a report consists of a SELECT-expression from the 'ticket' table, using the available columns and sorting the way you want it.
The ticket table has the following columns:
See TracTickets for a detailed description of the column fields.
all active tickets, sorted by priority and time
Example: All active tickets, sorted by priority and time
SELECT id AS ticket, status, severity, priority, owner,
For more flexible reports, Trac supports the use of dynamic variables in report SQL statements. In short, dynamic variables are special strings that are replaced by custom data before query execution.
The syntax for dynamic variables is simple, any upper case word beginning with '$' is considered a variable.
SELECT id AS ticket,summary FROM ticket WHERE priority='$PRIORITY'
To assign a value to $PRIORITY when viewing the report, you must define it as an argument in the report URL, leaving out the the leading '$'.
To use multiple variables, separate them with an '&'.
There is one magic dynamic variable to allow practical reports, its value automatically set without having to change the URL.
Example (List all tickets assigned to me):
SELECT id AS ticket,summary FROM ticket WHERE owner='$USER'
Trac is also capable of more advanced reports, including custom layouts, result grouping and user-defined CSS styles. To create such reports, we'll use specialized SQL statements to control the output of the Trac report engine.
To format reports, TracReports looks for 'magic' column names in the query result. These 'magic' names are processed and affect the layout and style of the final report.
SELECT id as ticket, created, status, summary FROM ticket
Columns whose names begin and end with 2 underscores (Example: __color__) are assumed to be formatting hints, affecting the appearance of the row.
Example: List active tickets, grouped by milestone, colored by priority
SELECT p.value AS __color__,
Note: A table join is used to match ticket priorities with their numeric representation from the enum table.
By default, all columns on each row are display on a single row in the HTML report, possibly formatted according to the descriptions above. However, it's also possible to create multi-line report entries.
Example: List active tickets, grouped by milestone, colored by priority, with description and multi-line layout
SELECT p.value AS __color__,
If you have added custom fields to your tickets (experimental feature in v0.8, 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.
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 TracIniReportCustomFieldSample? for some examples.
