Perl API: list of available queues, owners, status

Hello,

Is there a way/example of how to get a list of queues, owners, status
using the Perl API?

I want to cycle through making a list counts for each owner
and queue by status.

Thanks Richard

You want count tickets groupped by queue, owner and status, right? You
really don't want to iterate over anything. It will be very slow.
Instead take a look at how QueueSummaryBy* files do it in RT 4.0 and
how RT::Extension::SummaryByUser (on CPAN) does similar task. You just
need to combine two tables into one big table.

Re: Perl API: list of available queues, owners, status [In reply to]

Hi,

I am doing some ASCII perl reports and one of the options is to supply
the queue name. I want to be able to get a list of the queues that
are available as an input check.

In that case, it's probably easier to ->Load the queue by name and see
if it exists, rather than list 20 queues and name compare each.

Re: Perl API: list of available queues, owners, status [In reply to]

OK, that gets me the queue list.

Is there an API way to get the full list of valid status values and also
the list of names of ticket owners. I have looked that the code
that Ruslan mentions but I am able see how to get at the owner
list and list of valid status values.

thanks

I know how to this sort of thing with RAW SQL but prefer to try to
use the API.

I have looked at QueueSummaryByStatus in RT4 but

thanks

Have you tried running perldoc /opt/rt4/lib/RT/Queue.pm
and searching for Status?

Look at what the SelectOwner template does to get an owner list.

That's part of the configuration; it's not an API as such. That information is all configurable by you in the %Lifecycle configuration (look in RT_Config.pm).

See the documentation for the RT::Lifecycle module:

my $lifecycle = RT::Lifecycle->Load('default');
my @statuses = $lifecycle->Valid;

probably gets you what you want. Most of the perl classes that the BestPractical guys expect us to use in scripts have reasonable pod documentation, although often you have to remember to also consult the superclass documentation as well, since sometimes the documentation is at that level, in things like RT::Record and RT::SearchBuilder.

Well, you can always construct that from any list of tickets that you've previously obtained. The method is similar to the one mentioned before for iterating over queues; instead, you iterate over the tickets and fetch the name of the owner from each one. Note that this is likely to be quite slow if there are a lot of tickets.

You could, of course query the database directly, with something like:

select distinct(u.Name) from Users u, Tickets t where t.Owner = u.id;

but querying the database directly is not generally considered a smart thing to do, although I doubt this part of the schema is going to change any time soon.

I find that most of the RT code base itself is usually fairly clear (with the exceptions of some of the hairier web interface corners), and when I want to find out how to do something in the RT API I just search the main RT code for places where the same thing is being done, and copy it!

You really don't want to go about it that way.
You want to ask the Queue for the valid statuses, which is why I
pointed to the perldoc for Queue.pm.
A Queue object can get you both global and queue specific sets of
statuses, and it can also tell you if a Status is valid for a given
Queue.

This is a list of people who are currently Owners, which is not
actually the same as people who can be owners.

Re: Perl API: list of available queues, owners, status [In reply to]

Ok, I am nearly there. Yes, I have looked the perldoc but got a little
lost. It is very comprehensive but Perl is my third language :).

I am nearly there. I need the list of possible ticket owners. This is the
list of people in the admin group, maybe.

My previous report scripts used raw sql but I want to rewrite the reports
using as much of the RT API code bases as possible.

Below I summarise the input on getting the valid status values; note
we have some extra ones and the queuses

my $lifecycle = RT::Lifecycle->Load('default');
my @statuses = $lifecycle->Valid;

for my $status (@statuses) {
print $status, "\n";
}

my $queues = RT::Queues->new( RT->SystemUser );
$queues->UnLimit;
while ( my $queue = $queues->Next ) {
print $queue->Name, "\n";
}

So, is there something simialar that list the members who
can own a ticket?

thanks

Re: Perl API: list of available queues, owners, status [In reply to]

OK, I have looked at:

the SelectOwnerDrop template and came up with this which does
what I want to get the list of valid owners:

my $Users = RT::Users->new( RT->SystemUser );
$Users->WhoHaveRight(
Right => 'OwnTicket',
);

while ( my $Users = $Users->Next ) {
print $Users->Name, "\n";
}

Thanks for the pointer

I stand corrected.

The method is similar to the one mentioned before for iterating over queues; instead, you iterate over the tickets and fetch the name of the owner from each one. Note that this is likely to be quite slow if there are a lot of tickets.

I must have misinterpreted the question. If that's what he's after, then I'd have looked at the Mason components which provide a list of possible owners for a ticket, and copy the way that does it.

Yep, that's where I pointed him and where he eventually found it.

I'd still implement this by accepting a user name, loading and error
checking the name and then checking HasRight on the user and the
Queue, but there are many ways to do this.
