Trac Ticket Queries

Table of Contents

In addition to reports, Trac provides support for custom ticket queries, used to display lists of tickets meeting a specified set of 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 filters will display all open tickets, or if you're logged in it will display open tickets assigned to you. Current filters can be removed by clicking the button to the right with the minus sign on the label. New filters are added from the pulldown list in the bottom-right corner of the filters box. Filters with either a text box or a pulldown menu of options can be added multiple times to perform an or of 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.

Once you've edited your filters click the Update button to refresh your results.

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

While Trac does not yet allow saving a named query and somehow making it available in a navigable list, you can save references to queries in Wiki content, as described below.

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:

Active tickets against 1.0

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:

Assigned tickets by owner

Using the [[TicketQuery]] Macro

The ​TicketQuery macro lets you display lists of tickets matching certain criteria anywhere you can use WikiFormatting.

Example: 

[[TicketQuery(version=0.6|0.7&resolution=duplicate)]]

This is displayed as:

#4
Spike Lowess
#5
Center on assay
#6
QQPlot
#7
Merge on genesymbol
#8
COPA
#9
Error in ReplicateError
#10
ReplicateError
#11
Pinbaes normalization
#16
BasicReporter and BasicSpot
#18
AnnotationFiletr
#19
RMA plugin should check that cel files are assigned to correct cdf.
#20
extra values pass through
#92
Create Illumina SNP raw data type
#125
MeV ... files are now supported (by the BASEcore) in the BASE analysis tree
#192
MeV unable to launch appplication ... class not found exception
#245
net.sf.basedb.illumina: Detection P-value fails if there is no negative controls in bioassayset
#296
VirtualArray plug-in can't be installed
#347
Exception when trying to register more than one specimen tube for a case
#393
Change default value for protocol in "RNA quality control - create aliquots" wizard step 2
#634
Retraction wizard
#866
Implement the "Start page" extension

Just like the query: wiki links, the parameter of this macro expects a query string formatted according to the rules of the simple ticket query language.

A more compact representation without the ticket summaries is also available: 

[[TicketQuery(version=0.6|0.7&resolution=duplicate, compact)]]

This is displayed as:

#4, #5, #6, #7, #8, #9, #10, #11, #16, #18, #19, #20, #92, #125, #192, #245, #296, #347, #393, #634, #866

Finally if you wish to receive only the number of defects that match the query using the count parameter. 

[[TicketQuery(version=0.6|0.7&resolution=duplicate, count)]]

This is displayed as:

21

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 by placing pipes (|) between the columns like below: 

[[TicketQuery(max=3,status=closed,order=id,desc=1,format=table,col=resolution|summary|owner|reporter)]]

This is displayed as:

Full rows

In table format you can also have full rows by using rows=<field> like below: 

[[TicketQuery(max=3,status=closed,order=id,desc=1,format=table,col=resolution|summary|owner|reporter,rows=description)]]

This is displayed as:

It seems to be related to the code that was added in #1547 to allow for any-to-any links. There is a check for null on the line after so we probably only need to re-order them.

#1579 fixed WGS FASTQ management wizard should use new API method for checking if a file exists Nicklas Nordborg Nicklas Nordborg
Description

See #1578. The current method that opens a stream suffers from a problem that causes the wizard to crash if the number of scanned files is larger than the limit set by ulimit -n.

#1578 fixed Implement a method for getting file metadata without opening a stream Nicklas Nordborg Nicklas Nordborg
Description

The RemoteSession class have several methods for downloading a file, and some of them will return metadata such as size and modification date in a separate object (FileMetaData). There are cases when we only want to get the metadata without starting a download and there is really no need to open a stream. It would be nice to have separate method for this.

Query Language

query: TracLinks and the [[TicketQuery]] macro both use a mini “query language” for specifying query filters. Basically, the filters are separated by ampersands (&). Each filter then 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.

The available operators are:

= the field content exactly matches the 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
