+Does principal baz have right foo for object bar
-# {{{ Requirements
+What rights does user baz have for object bar
-Here's the rough scheme I was thinking of for RT2 acls. Thoughts? I think
-it's a lot more flexible than RT 1.0, but not so crazily complex that
-it will be impossible to implement. One of the "interesting" features
-is the ability to grant acls based on watcher status. This now lives
-in design-docs/acls
+# {{{ Which principals have right foo for object bar
- jesse
-Who can rights be granted to:
+if ($args{'ObjectType'} eq 'Ticket') {
+ $or_check_ticket_roles = " OR ( Groups.Domain = 'TicketRole' AND Groups.Instance = '".$args{'ObjectId'}."') ";
+ # If we're looking at ticket rights, we also want to look at the associated queue rights.
+ # this is a little bit hacky, but basically, now that we've done the ticket roles magic, we load the queue object
+ # and ask all the rest of our questions about the queue.
+ my $tick = RT::Ticket->new($RT::SystemUser);
+ $tick->Load($args{'ObjectId'});
+ $args{'ObjectType'} = 'Queue';
+ $args{'ObjectId'} = $tick->QueueObj->Id();
