NAME ^

RT::Client::REST -- talk to RT installation using REST protocol.

SYNOPSIS ^

  use Error qw(:try);
  use RT::Client::REST;

  my $rt = RT::Client::REST->new(
    server => 'http://example.com/rt',
    timeout => 30,
  );

  try {
    $rt->login(username => $user, password => $pass);
  } catch Exception::Class::Base with {
    die "problem logging in: ", shift->message;
  };

  try {
    # Get ticket #10
    $ticket = $rt->show(type => 'ticket', id => 10);
  } catch RT::Client::REST::UnauthorizedActionException with {
    print "You are not authorized to view ticket #10\n";
  } catch RT::Client::REST::Exception with {
    # something went wrong.
  };

DESCRIPTION ^

RT::Client::REST is /usr/bin/rt converted to a Perl module. I needed to implement some RT interactions from my application, but did not feel that invoking a shell command is appropriate. Thus, I took rt tool, written by Abhijit Menon-Sen, and converted it to an object-oriented Perl module.

USAGE NOTES ^

This API mimics that of 'rt'. For a more OO-style APIs, please use RT::Client::REST::Object-derived classes: RT::Client::REST::Ticket and RT::Client::REST::User. not implemented yet).

METHODS ^

new ()

The constructor can take these options (note that these can also be called as their own methods):

server

server is a URI pointing to your RT installation.

If you have already authenticated against RT in some other part of your program, you can use _cookie parameter to supply an object of type HTTP::Cookies to use for credentials information.

timeout

timeout is the number of seconds HTTP client will wait for the server to respond. Defaults to LWP::UserAgent's default timeout, which is 300 seconds.

basic_auth_cb

This callback is to provide the HTTP client (based on LWP::UserAgent) with username and password for basic authentication. It takes the same arguments as get_basic_credentials() of LWP::UserAgent and returns username and password:

  $rt->basic_auth_cb( sub {
    my ($realm, $uri, $proxy) = @_;
    # do some evil things
    return ($username, $password);
  }
login (username => 'root', password => 'password') =item login (my_userfield => 'root', my_passfield => 'password')

Log in to RT. Throws an exception on error.

Usually, if the other side uses basic HTTP authentication, you do not have to log in, but rather prodive HTTP username and password instead. See basic_auth_cb above.

show (type => $type, id => $id)

Return a reference to a hash with key-value pair specifying object $id of type $type.

edit (type => $type, id => $id, set => { status => 1 })

Set fields specified in parameter set in object $id of type $type.

create (type => $type, set => \%params, text => $text)

Create a new object of type $type and set initial parameters to %params. For a ticket object, 'text' parameter can be supplied to set the initial text of the ticket. Returns numeric ID of the new object. If numeric ID cannot be parsed from the response, RT::Client::REST::MalformedRTResponseException is thrown.

search (type => $type, query => $query, %opts)

Search for object of type $type by using query $query. For example:

  # Find all stalled tickets
  my @ids = $rt->search(
    type => 'ticket',
    query => "Status = 'stalled'",
  );

%opts is a list of key-value pairs:

orderby

The value is the name of the field you want to sort by. Plus or minus sign in front of it signifies ascending order (plus) or descending order (minus). For example:

  # Get all stalled tickets in reverse order:
  my @ids = $rt->search(
    type => 'ticket',
    query => "Status = 'stalled'",
    orderby => '-id',
  );

search returns the list of numeric IDs of objects that matched your query. You can then use these to retrieve object information using show() method:

  my @ids = $rt->search(
    type => 'ticket',
    query => "Status = 'stalled'",
  );
  for my $id (@ids) {
    my ($ticket) = $rt->show(type => 'ticket', ids => [$id]);
    print "Subject: ", $t->{Subject}, "\n";
  }
comment (ticket_id => $id, message => $message, %opts)

Comment on a ticket with ID $id. Optionally takes arguments cc and bcc which are references to lists of e-mail addresses and attachments which is a list of filenames to be attached to the ticket.

  $rt->comment(
    ticket_id   => 5,
    message     => "Wild thing, you make my heart sing",
    cc          => [qw(dmitri@localhost some@otherdude.com)],
  );
correspond (ticket_id => $id, message => $message, %opts)

Add correspondence to ticket ID $id. Takes optional cc, bcc, and attachments parameters (see comment above).

get_attachment_ids (id => $id)

Get a list of numeric attachment IDs associated with ticket $id.

get_attachment (parent_id => $parent_id, id => $id)

Returns reference to a hash with key-value pair describing attachment $id of ticket $parent_id. (parent_id because -- who knows? -- maybe attachments won't be just for tickets anymore in the future).

get_transaction_ids (parent_id => $id, %opts)

Get a list of numeric IDs associated with parent ID $id. %opts have the following options:

type

Type of the object transactions are associated wtih. Defaults to "ticket" (I do not think server-side supports anything else). This is designed with the eye on the future, as transactions are not just for tickets, but for other objects as well.

transaction_type

If not specified, IDs of all transactions are returned. If set to a scalar, only transactions of that type are returned. If you want to specify more than one type, pass an array reference.

Transactions may be of the following types (case-sensitive):

AddLink
AddWatcher
Comment
Correspond
Create
CustomField
DeleteLink
DelWatcher
EmailRecord
Give
Set
Status
Steal
Take
Told
get_transaction (parent_id => $id, id => $id, %opts)

Get a hashref representation of transaction $id associated with parent object $id. You can optionally specify parent object type in %opts (defaults to 'ticket').

merge_tickets (src => $id1, dst => $id2)

Merge ticket $id1 into ticket $id2.

link_tickets (src => $id1, dst => $id2, link_type => $type)

Create a link between two tickets. A link type can be one of the following:

  • DependsOn
  • DependedOnBy
  • RefersTo
  • ReferredToBy
  • HasMember
  • MemberOf
unlink_tickets (src => $id1, dst => $id2, link_type => $type)

Remove a link between two tickets (see link_tickets())

take (id => $id)

Take ticket $id. This will throw RT::Client::REST::AlreadyTicketOwnerException if you are already the ticket owner.

untake (id => $id)

Untake ticket $id. This will throw RT::Client::REST::AlreadyTicketOwnerException if Nobody is already the ticket owner.

steal (id => $id)

Steal ticket $id. This will throw RT::Client::REST::AlreadyTicketOwnerException if you are already the ticket owner.

EXCEPTIONS ^

When an error occurs, this module will throw exceptions. I recommend using Error.pm's try{} mechanism to catch them, but you may also use simple eval{}. The former will give you flexibility to catch just the exceptions you want.

Please see RT::Client::REST::Exception for the full listing and description of all the exceptions.

LIMITATIONS ^

Beginning with version 0.14, methods edit() and show() only support operating on a single object. This is a conscious departure from semantics offered by the original tool, as I would like to have a precise behavior for exceptions. If you want to operate on a whole bunch of objects, please use a loop.

DEPENDENCIES ^

The following modules are required:

SEE ALSO ^

LWP::UserAgent, RT::Client::REST::Exception

BUGS ^

Most likely. Please report.

VARIOUS NOTES ^

RT::Client::REST does not (at the moment, see TODO file) retrieve forms from RT server, which is either good or bad, depending how you look at it.

VERSION ^

This is version 0.40 of RT::Client::REST.

AUTHORS ^

Original /usr/bin/rt was written by Abhijit Menon-Sen <ams@wiw.org>. rt was later converted to this module by Dmitri Tikhonov <dtikhonov@yahoo.com>. In January of 2008, Damien "dams" Krotkine <dams@cpan.org> joined as the project's co-maintainer. JLMARTIN has become co-maintainer as of March 2010.

LICENSE ^

Since original rt is licensed under GPL, so is this module.
