Name

Bric::Biz::Workflow - Controls the progress of an asset through a series of desks.

Synopsis

my $flow = new Bric::Biz::Workflow($param);

$id    = $flow->get_id;

$name  = $flow->get_name;
$flow  = $flow->set_name($name);

$site_id = $flow->get_site_id;
$flow    = $flow->set_site_id($site_id);

$desc  = $flow->get_description;
$flow  = $flow->set_description($desc);

$flow  = $flow->add_desk($param);

# Returns a list of allowed desks.
@desks = $flow->allowed_desks();

# Lists the required desks
@desks = $flow->required_desks();

Description

A workflow is something that guides an asset through a set of desks, where an asset is any kind of creative content (a story, an image, a sound file, etc) and a desk performs and kind of validation or transformation upon an asset needed before it can be published. Example desks might be a 'legal' desk where users can verify any legal issue for a particular asset, or an 'edit' desk where users can check consistancy and presentation for an asset.

A workflow might be as simple as a linear path through a set of desks or as complex as requiring certain desks be visited with other desks optional and a route through the desks that can be arbitrarily complex.

Interface

Constructors

$success = $obj = new Bric::Biz::Workflow($param);

Keys for $param are:

• name

  The name for this workflow

• site_id

  The site this workflow belongs to

• description

  A description for this workflow

• start_desk

  The starting desk for this workflow

Throws:

NONE

Side Effects:

NONE

Notes:

NONE

my $wf = Bric::Biz::Workflow->lookup({ id => $id });

my $wf = Bric::Biz::Workflow->lookup({ name => $name });

Looks up and instantiates a new Bric::Biz::Workflow object based on an Bric::Biz::Workflow object ID or name. If no output channelobject is found in the database, lookup() returns undef.

Throws:

• Unable to prepare SQL statement.

• Unable to connect to database.

• Unable to select column into arrayref.

• Unable to execute SQL statement.

• Unable to bind to columns to statement handle.

• Unable to fetch row from statement handle.

Side Effects: NONE.

Notes: NONE.

(@all || $all) = Bric::Biz::Workflow->list($params);

Return a list of all known workflow types. Keys of the $params hash reference are:

id

Workflow ID. May use ANY for a list of possible values.

name

Return all workflows matching a certain name. May use ANY for a list of possible values.

site_id

Return all workflows matching a certain site id. May use ANY for a list of possible values.

description

Return all workflows with a matching description. May use ANY for a list of possible values.

description

Return all workflows with a matching description. May use ANY for a list of possible values.

active

Boolean; Return all in/active workflows.

type

Return all workflows of a particular type. The types are integers accessible via the STORY_WORKFLOW, MEDIA_WORKFLOW, and TEMPLATE_WORKFLOW constants. May use ANY for a list of possible values.

<desk_id>

Return all workflows containing a desk with this desk ID. May use ANY for a list of possible values.

grp_id

Return all workflows in the group corresponding to this group ID. May use ANY for a list of possible values.

Throws:

• Unable to prepare SQL statement.

• Unable to connect to database.

• Unable to select column into arrayref.

• Unable to execute SQL statement.

• Unable to bind to columns to statement handle.

• Unable to fetch row from statement handle.

Side Effects: NONE.

Notes: Seaches against name and description use the LIKE operator, so '%' can be used for substring searching.

(@ids || $ids) = Bric::Biz::Workflow->list_ids($params);

Return a list of workflow IDs. See list() for a list of the relevant keys in the $params hash reference.

Throws:

• Unable to prepare SQL statement.

• Unable to connect to database.

• Unable to select column into arrayref.

• Unable to execute SQL statement.

• Unable to bind to columns to statement handle.

• Unable to fetch row from statement handle.

Destructors

$self->DESTROY

Dummy method to prevent wasting time trying to AUTOLOAD DESTROY.

Public Class Methods

my $meths = Bric::Biz::Workflow->my_meths

my (@meths || $meths_aref) = Bric::Biz::Workflow->my_meths(TRUE)

my (@meths || $meths_aref) = Bric::Biz::Workflow->my_meths(0, TRUE)

Returns an anonymous hash of introspection data for this object. If called with a true argument, it will return an ordered list or anonymous array of introspection data. If a second true argument is passed instead of a first, then a list or anonymous array of introspection data will be returned for properties that uniquely identify an object (excluding id, which is assumed).

Each hash key is the name of a property or attribute of the object. The value for a hash key is another anonymous hash containing the following keys:

name

The name of the property or attribute. Is the same as the hash key when an anonymous hash is returned.

disp

The display name of the property or attribute.

get_meth

A reference to the method that will retrieve the value of the property or attribute.

get_args

An anonymous array of arguments to pass to a call to get_meth in order to retrieve the value of the property or attribute.

set_meth

A reference to the method that will set the value of the property or attribute.

set_args

An anonymous array of arguments to pass to a call to set_meth in order to set the value of the property or attribute.

type

The type of value the property or attribute contains. There are only three types:

short

date

blob

len

If the value is a 'short' value, this hash key contains the length of the field.

search

The property is searchable via the list() and list_ids() methods.

req

The property or attribute is required.

props

An anonymous hash of properties used to display the property or attribute. Possible keys include:

type

The display field type. Possible values are

text

textarea

password

hidden

radio

checkbox

select

length

The Length, in letters, to display a text or password field.

maxlength

The maximum length of the property or value - usually defined by the SQL DDL.

rows

The number of rows to format in a textarea field.

cols

The number of columns to format in a textarea field.

vals

An anonymous hash of key/value pairs reprsenting the values and display names to use in a select list.
