88 RT::Lifecycle - class to access and manipulate lifecycles
92 A lifecycle is a list of statuses that a ticket can have. There are three
93 groups of statuses: initial, active and inactive. A lifecycle also defines
94 possible transitions between statuses. For example, in the 'default' lifecycle,
95 you may only change status from 'stalled' to 'open'.
97 It is also possible to define user-interface labels and the action a user
98 should perform during a transition. For example, the "open -> stalled"
99 transition would have a 'Stall' label and the action would be Comment. The
100 action only defines what form is showed to the user, but actually performing
101 the action is not required. The user can leave the comment box empty yet still
102 Stall a ticket. Finally, the user can also just use the Basics or Jumbo form to
103 change the status with the usual dropdown.
109 Simple constructor, takes no arguments.
115 my $self = bless {}, ref($proto) || $proto;
117 $self->FillCache unless keys %LIFECYCLES_CACHE;
124 Takes a name of the lifecycle and loads it. If name is empty or undefined then
125 loads the global lifecycle with statuses from all named lifecycles.
127 Can be called as class method, returns a new object, for example:
129 my $lifecycle = RT::Lifecycle->Load('default');
135 my $name = shift || '';
136 return $self->new->Load( $name, @_ )
139 return unless exists $LIFECYCLES_CACHE{ $name };
141 $self->{'name'} = $name;
142 $self->{'data'} = $LIFECYCLES_CACHE{ $name };
149 Returns sorted list of the lifecycles' names.
156 $self->FillCache unless keys %LIFECYCLES_CACHE;
158 return sort grep length && $_ ne '__maps__', keys %LIFECYCLES_CACHE;
163 Returns name of the laoded lifecycle.
167 sub Name { return $_[0]->{'name'} }
171 Returns L<RT::Queues> collection with queues that use this lifecycle.
178 my $queues = RT::Queues->new( RT->SystemUser );
179 $queues->Limit( FIELD => 'Lifecycle', VALUE => $self->Name );
183 =head2 Getting statuses and validating.
185 Methods to get statuses in different sets or validating them.
189 Returns an array of all valid statuses for the current lifecycle.
190 Statuses are not sorted alphabetically, instead initial goes first,
191 then active and then inactive.
193 Takes optional list of status types, from 'initial', 'active' or
194 'inactive'. For example:
196 $lifecycle->Valid('initial', 'active');
204 return @{ $self->{'data'}{''} || [] };
208 push @res, @{ $self->{'data'}{ $_ } || [] } foreach @types;
214 Takes a status and returns true if value is a valid status for the current
215 lifecycle. Otherwise, returns false.
217 Takes optional list of status types after the status, so it's possible check
218 validity in particular sets, for example:
220 # returns true if status is valid and from initial or active set
221 $lifecycle->IsValid('some_status', 'initial', 'active');
229 my $value = shift or return 0;
230 return 1 if grep lc($_) eq lc($value), $self->Valid( @_ );
236 Takes a status and returns its type, one of 'initial', 'active' or
244 foreach my $type ( qw(initial active inactive) ) {
245 return $type if $self->IsValid( $status, $type );
252 Returns an array of all initial statuses for the current lifecycle.
258 return $self->Valid('initial');
263 Takes a status and returns true if value is a valid initial status.
264 Otherwise, returns false.
270 my $value = shift or return 0;
271 return 1 if grep lc($_) eq lc($value), $self->Valid('initial');
278 Returns an array of all active statuses for this lifecycle.
284 return $self->Valid('active');
289 Takes a value and returns true if value is a valid active status.
290 Otherwise, returns false.
296 my $value = shift or return 0;
297 return 1 if grep lc($_) eq lc($value), $self->Valid('active');
303 Returns an array of all inactive statuses for this lifecycle.
309 return $self->Valid('inactive');
314 Takes a value and returns true if value is a valid inactive status.
315 Otherwise, returns false.
321 my $value = shift or return 0;
322 return 1 if grep lc($_) eq lc($value), $self->Valid('inactive');
327 =head2 Default statuses

347 Returns the status that should be used by default
348 when ticket is created.

358 =head3 DefaultOnMerge
360 Returns the status that should be used when tickets
367 return $self->DefaultStatus('on_merge');
370 =head2 Transitions, rights, labels and actions.
374 Takes status and returns list of statuses it can be changed to.
376 Is status is empty or undefined then returns list of statuses for
379 If argument is ommitted then returns a hash with all possible
380 transitions in the following format:
382 status_x => [ next_status, next_status, ... ],
383 status_y => [ next_status, next_status, ... ],
389 return %{ $self->{'data'}{'transitions'} || {} }

398 Takes two statuses (from -> to) and returns true if it's valid
399 transition and false otherwise.

413 Takes two statuses (from -> to) and returns the right that should
414 be checked on the ticket.
