Trac Ticket Queries

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 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 and no name/email defined in the preferences then all open issues are displayed.

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 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 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

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.

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:

No results

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:

No results

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:

0

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:

#29787 needsinfo ForeignKey to User with BigIntegerField id/pk gets created as 'integer' instead of 'bigint' field in postgres nobody Andrew Badr
Description

I ran into this bug when upgrading from 1.10 to 1.11. All my models have BigInteger ids. My test case creates a User model instance, then creates another model instance pointing to it via ForeignKey. On 1.10, this works fine, and inspecting the database shows the fk field as having type 'bigint' in postgres. On 1.11, the test fails, and inspecting the db shows the field as a regular 'integer'.

After some digging, I've found that this bug happens, oddly, at different commits for different models. For some models (??) it occurs starting in 45ded053b1f4320284aa5dac63052f6d1baefea9 (#27666). For others, b8a2f3c2d66aa15af4be745a576609b958a853c0 is the first bad commit (fix for #28305; comes between 1.11.7 and 1.11.8). The fact that the former has to do with migrations might be a clue.

I tried to repro with a minimal test case on a fresh project, but sadly was not able to recreate the bug. (It worked fine.) So there must be some other config in my project that's affecting this. If I have time I'll try to pin it down (already spent ~4 hours on this), but maybe someone who worked on the relevant patches can make an educated guess on what's happening?

#29786 wontfix Add option to lock rows with select_for_update() immediately nobody ovalseven8
Description

In my web application I usually follow the "fat models, lightweight views" philosophy.

To put it in a nutshell, I have two models in my app called "Event" and "Registration (for Event)":

class Event(models.Model):
    capacity = models.PositiveSmallIntegerField()

    def get_number_of_registered_tickets():
        return EventRegistration.objects.filter(event__exact=self).aggregate(total=Coalesce(Sum('number_tickets'), 0))['total']
    
    @transaction.atomic
    def reserve_tickets(self, number_tickets):
        Event.objects.filter(id=self.id).select_for_update()
        if self.get_number_of_registered_tickets() + number_tickets <= self.capacity:
            # create EventRegistration
        else:
            # handle error


class EventRegistration(models.Model):
    time = models.DateTimeField(auto_now_add=True)
    event = models.ForeignKey(Event, on_delete=models.CASCADE)
    number_tickets = models.PositiveSmallIntegerField(validators=[MinValueValidator(1)])

Now, let's say for a specific event only one ticket is left and two users want to buy that ticket concurrently. Under unfortunate circumstances (when I do not use locking), it would be possible that both get the ticket and now I have a problem. So, I need to make sure that the registration for an event happens in sequence. That's the reason why I use select_for_update() in the method reserve_tickets() above.

Unfortunately, the row is only locked when the QuerySet is evaluates what's not the case here. So, I need more or less a "dirty hack" like printing the queryset or creating a list etc.

While this works, I do not think it's a nice solution. Especially for locking rows, I think it would be a good think if Django had a "lock/evaluate immediately" option.

Different ideas how the solution API could look like: select_for_update().evaluate() select_for_update(evaluate_immediately=True)

Of course, there're more possibilities. I think it would be a nice little feature and lazy evaluation is something you perhaps do not want for locking.

So my question is if you're open for that, if yes I could look into it.

#29785 invalid Using {{ csrf_token }} throws exception (AttributeError: 'dict' object has no attribute 'META') if no render context nobody jeffrey k eliasen
Description

Calling render() with no context on a template that uses {{ csrf_token }} results in an exception being thrown.

I believe the appropriate fix is to change:

if "CSRF_COOKIE" not in request.META:

to:

if not request or not request.META or "CSRF_COOKIE" not in request.META:

I am happy to create a PR for this issue once I know it is a desired fix.

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. To include a litteral & or | in a value, escape the character with a backslash (\).

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

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 left out 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
