Trac Ticket Queries
Table of Contents
In addition to reports, Trac provides support for custom ticket queries, which can be used to display tickets that meet specified criteria.
To configure and execute a custom query, switch to the View Tickets module from the navigation bar, and select the Custom Query link.
Filters
When you first go to the query page, the default filter will display tickets relevant to you:
- If logged in then all open tickets, it will display open tickets assigned to you.
- If not logged in but you have specified a name or email address in the preferences, then it will display all open tickets where your email (or name if email not defined) is in the CC list.
- If not logged in and no name/email is defined in the preferences, then all open issues are displayed.
Current filters can be removed by clicking the button to the left with the minus sign on the label. New filters are added from the pulldown lists at the bottom corners of the filters box; 'And' conditions on the left, 'Or' conditions on the right. Filters with either a text box or a pulldown menu of options can be added multiple times to perform an Or on the criteria.
You can use the fields just below the filters box to group the results based on a field, or display the full description for each ticket.
After you have edited your filters, click the Update button to refresh your results.
Navigating Tickets
Clicking on one of the query 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 Query link to return to the query page.
You can safely edit any of the tickets and continue to navigate through the results using the Next/Previous/Back to Query links after saving your results. When you return to the query any tickets which were edited will be displayed with italicized text. If one of the tickets was edited such that it no longer matches the query criteria , the text will also be greyed. Lastly, if a new ticket matching the query criteria has been created, it will be shown in bold.
The query results can be refreshed and cleared of these status indicators by clicking the Update button again.
Saving Queries
Trac allows you to save the query as a named query accessible from the reports module. To save a query ensure that you have Updated the view and then click the Save query button displayed beneath the results. You can also save references to queries in Wiki content, as described below.
Note: one way to easily build queries like the ones below, you can build and test the queries in the Custom report module and when ready - click Save query. This will build the query string for you. All you need to do is remove the extra line breaks.
Note: you must have the REPORT_CREATE permission in order to save queries to the list of default reports. The Save query button will only appear if you are logged in as a user that has been granted this permission. If your account does not have permission to create reports, you can still use the methods below to save a query.
Using TracLinks
You may want to save some queries so that you can come back to them later. You can do this by making a link to the query from any Wiki page.
[query:status=new|assigned|reopened&version=1.0 Active tickets against 1.0]
Which is displayed as:
This uses a very simple query language to specify the criteria, see Query Language.
Alternatively, you can copy the query string of a query and paste that into the Wiki link, including the leading ? character:
[query:?status=new&status=assigned&status=reopened&group=owner Assigned tickets by owner]
Which is displayed as:
Customizing the table format
You can also customize the columns displayed in the table format (format=table) by using col=<field>. You can specify multiple fields and what order they are displayed in by placing pipes (|) between the columns:
[[TicketQuery(max=3,status=closed,order=id,desc=1,format=table,col=resolution|summary|owner|reporter)]]
This is displayed as:
| Ticket | Resolution | Summary | Owner | Reporter |
|---|---|---|---|---|
| #5 | fixed | XTIDE cannot boot from hard disk | somebody | 16bitPM |
| #3 | invalid | Problem formatting in 1.2 MByte drive | somebody | dergrell |
| #2 | fixed | issue with partition detection in XT-CF lite Rev 2 XUB R602 | somebody | twospruces |
Full rows
In table format you can also have full rows by using rows=<field>:
[[TicketQuery(max=3,status=closed,order=id,desc=1,format=table,col=resolution|summary|owner|reporter,rows=description)]]
This is displayed as:
| Ticket | Resolution | Summary | Owner | Reporter |
|---|---|---|---|---|
| #5 | fixed | XTIDE cannot boot from hard disk | somebody | 16bitPM |
| Description |
I have a clone 80286 computer with 5MiB of RAM and a Maxtor DiamondMax Plus 8 drive. XTIDE is configured on a network card with EPROM socket. XTIDE has been configured for 1 IDE controller, with interrupts enabled. This system was working successfully before, until the drive slowed down more and more, notably during the boot process. At a given point, the computer started to hang at the point "Loading MS-DOS..." needing a hard reset. I made the following attempts:
As a final resort, I will try to manually configure with interrupts disabled, but theoretically this shouldn't make any difference since both IRQ lines on that computer are free anyway. Please let me know if you need further information. |

| #3 | invalid | Problem formatting in 1.2 MByte drive | somebody | dergrell |
| Description |
hi: formatting 1.2 Mbyte disks shows many many bad sectors only on the NuXT. No errors occur on a Pentium II PC using the identical two drives, which work properly there on. My suspicion: Error in INT 13h not deleting the double stepping that is used for 360 KB disks. And of course HD disks were used. XUB was BIOS 0.9.8 |

| #2 | fixed | issue with partition detection in XT-CF lite Rev 2 XUB R602 | somebody | twospruces |
| Description |
Problem described in some detail here: http://www.vcfed.org/forum/showthread.php?29749-XTIDE-Universal-BIOS-v2-0-0-beta-testing-thread&p=585647#post585647 This issue relates to the detection of the single partition on working, correctly formatted CF cards. Environment is:
Description:
Process to correctly boot the machine 1) hard restart/power cycle with at least 10sec off time 2) boot into boot loader menu, observe listed drives. if 2 FDD listed only, warm restart. if 16 "Foreign HDD" listed, repeat hard restart 3) after warm restart allow machine to boot to C drive. I can be contacted at twospruces at gmail for additional info. Thanks for any assistance. |

Query Language
query: TracLinks and the [[TicketQuery]] macro both use a mini “query language” for specifying query filters. Filters are separated by ampersands (&). Each filter consists of the ticket field name, an operator and one or more values. More than one value are separated by a pipe (|), meaning that the filter matches any of the values. To include a literal & or | in a value, escape the character with a backslash (\).
The available operators are:
| = | the field content exactly matches one of the values |
| ~= | the field content contains one or more of the values |
| ^= | the field content starts with one of the values |
| $= | the field content ends with one of the values |
All of these operators can also be negated:
| != | the field content matches none of the values |
| !~= | the field content does not contain any of the values |
| !^= | the field content does not start with any of the values |
| !$= | the field content does not end with any of the values |
The date fields created and modified can be constrained by using the = operator and specifying a value containing two dates separated by two dots (..). Either end of the date range can be left empty, meaning that the corresponding end of the range is open. The date parser understands a few natural date specifications like "3 weeks ago", "last month" and "now", as well as Bugzilla-style date specifications like "1d", "2w", "3m" or "4y" for 1 day, 2 weeks, 3 months and 4 years, respectively. Spaces in date specifications can be omitted to avoid having to quote the query string.
| created=2007-01-01..2008-01-01 | query tickets created in 2007 |
| created=lastmonth..thismonth | query tickets created during the previous month |
| modified=1weekago.. | query tickets that have been modified in the last week |
| modified=..30daysago | query tickets that have been inactive for the last 30 days |
