Trac Ticket Queries

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.

Some shortcuts can be used to manipulate checkbox filters.

  • Clicking on a filter row label toggles all checkboxes.
  • Pressing the modifier key while clicking on a filter row label inverts the state of all checkboxes.
  • Pressing the modifier key while clicking on a checkbox selects the checkbox and deselects all other checkboxes in the filter.

The modifier key is platform and browser dependent. On Mac the modified key is Option/Alt or Command. On Linux the modifier key is Ctrl + Alt. Opera on Windows seems to use Ctrl + Alt, while Alt is effective for other Windows browsers.

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.

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

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:

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:

#29450 duplicate Redirect using HTTP status "303 See Other" for django.http.response HttpResponseRedirect nobody Duane Hutchins
Description

Regarding: django.http.response HttpResponseRedirect

Current redirects use http status 302, which is fine most of the time, but it can cause issues if browser caching is permitted.

For example:

  • Cache-Control allows caching globally
  • User is logged in
  • User logs out (GET response = 302 redirect)
  • This response is cached by the browser
  • User logs back in
  • User attempts to log out again
  • Browse serves cached response from disk and redirects without request revalidation
  • Result: User is not actually logged out

Caching breaks the response, which is why HTTP Status 303 redirects do not allow caching. They are more appropriate than 302 redirects. https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.3

Note that 303 redirects are not HTTP/1.0 compatible. A quick check shows that every modern browser now supports http/1.1 or higher. Still, 302 redirect responses can still be served for http/1.0 requests, if that's a concern.

Two other tickets (#13277 and #6227) requested this fix 8+ years ago, and they were closed because http/1.0 was still in common use at the time.

Now that http/1.0 is no longer in common use, can we change this redirect to 303?

#29445 wontfix Compute defaults values with using of objects manager nobody Yurii Shtrikker
Description

Background: I have an issue for add a field used for ordering records to few models . Problem is pre-defined value, that should calculate as currently max value plus ten. For example: Add first record. Field should be a 10 by default. Add second record. Field should be a 20 by default. Add third record. Field should be a 30 by default, but we change it to 15 for placing between first two records. Add fourth record. Field should be a 30 by default.

For implement this logic I need access to class object when default method is called (I mean method specifying as value for default argument for field). But at method call I don't get any arguments. In case when I need implement this field for single model - I can use model name as his objects argument for this logic. But for many models I thinks it's will be bad. Abstract model also not a choice, because it doesn't have a objects manager.

So I remember about prepopulated fields in BaseModelAdmin (this all need inly for admin site), and I use formfield_for_dbfield for implementing this logic.

Now I want to ask about add new feature to add compute_defaults dict to BaseModelAdmin. Key used as field name selector and value as computing function (information about model and current field we can get from db_field variable). I can create PL with this feature by myself, but should I do it? Is it need to somebody else? And what you all thinking about this idea?

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
