SYNOPSIS

13        # in your action
14        sub execute {
15            my ( $self, $wf ) = @_;
16            my $current_user = $wf->context->param( 'current_user' );
17            # ... do your work with $ticket
18            $wf->add_history( action => 'create ticket',
19                              user   => $current_user->full_name,
20                              description => "Ticket $ticket->{subject} successfully created" );
21        }

23        # in your view (using TT2)
24        [% FOREACH history = workflow.get_history %]
25           On:     [% OI.format_date( history.date, '%Y-%m-%d %H:%M' ) %]<br>
26           Action: [% history.action %] (ID: [% history.id %])<br>
27           by:     [% history.user %]<br>
28           [% history.description %]
29        [% END %]

DESCRIPTION

32       Every workflow can record its history. More appropriately, every action
33       the workflow executes can deposit history entries in the workflow to be
34       saved later. Neither the action nor the workflow knows about how the
35       history is saved, just that the history is available.
36

METHODS

38   Public Methods
39       new( \%params )
40
41       Create a new history object, filling it with properties from
42       "\%params".
43
44       set_new_state( $new_state )
45
46       Assigns the new state $new_state to the history if the state is not
47       already assigned. This is used when you generate a history request in a
48       Workflow::Action since the workflow state will change once the action
49       has successfully completed. So in the action you create a history
50       object without the state:
51
52         $wf->add_history(
53             Workflow::History->new({
54                 action      => "Cocoa Puffs",
55                 description => "They're magically delicious",
56                 user        => "Count Chocula",
57             })
58         );
59
60       And then after the new state has been set but before the history
61       objects are stored the workflow sets the new state in all unsaved
62       history objects.
63
64       is_saved()
65
66       Returns true (1) if this history object has been saved, false (0) if
67       not.
68
69   Properties
70       ·   id - ID of history entry
71
72       ·   workflow_id - ID of workflow to which history is attached
73
74       ·   action - Brief description of action taken
75
76       ·   description - Lengthy description of action taken
77
78       ·   date - Date history noted, set to a DateTime object.
79
80       ·   time_zone - Time zone to pass to the DateTime object.
81
82       ·   user - User name (ID, login, or full name, up to you) taking action
83           (may be blank)
84
85       ·   state - State of workflow as history was recorded.
86
87       clear_saved
88
89       Sets saved state to false and returns 0
90
91       set_saved
92
93       Sets saved state to true and returns 1
