  use Bric::Biz::Asset::Business::Media;

Media contains all of the data that will result in published media files. It contains the metadata and associations with media documents. It inherits from Bric::Biz::Asset::Business

This will create a new media object with an optionally defined initial state Supported Keys:

*

user__id - Required.

*

active

*

priority

*

title - same as name

*

name - Will be overridden by title

*

description

*

workflow_id

*

element__id - Required unless asset type object passed

*

element - the object required unless id is passed

*

site_id - required

*

source__id - required

*

cover_date - will set expire date in conjunction with the source

*

media_type_id

*

category__id Throws: NONE. Side Effects: NONE. Notes: NONE. This will return a media asset that matches the criteria defined Throws: NONE. Side Effects: NONE. Notes: Inherited from Bric::Biz::Asset. returns a list or list ref of media objects that match the criteria defined Supported Keys:

title

The title of the media document. May use CWANY for a list of possible values.

name

Same as CWtitle.

description

Media Document description. May use CWANY for a list of possible values.

id

The media document ID. May use CWANY for a list of possible values.

version

The media document version number. May use CWANY for a list of possible values.

version_id

The ID of a version of a media document. May use CWANY for a list of possible values.

file_name

The media document file name. May use CWANY for a list of possible values.

user_id

Returns the versions that are checked out by the user, otherwise returns the most recent version. May use CWANY for a list of possible values.

checked_out

Indicates whether to list media that are checked out or not. If 0, then only non-checked out media will be returned. If 1, then only checked-out media will be returned. If all, then the checked_out attributed will be ignored (unless the CWuser__id parameter is passed).

checked_in

If passed a true value, this parameter causes the checked in version of the most current version of the media document to be returned. When a media document is checked out, there are two instances of the current version: the one checked in last, and the one currently being edited. When the CWchecked_in parameter is a true value, then the instance last checked in is returned, rather than the instance currently checked out. This is useful for users who do not currently have a media document checked out and wish to see the media document as of the last check in, rather than as currently being worked on in the current checkout. If a media document is not currently checked out, this parameter has no effect.

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 CWid, 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

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

set_args

type

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

type

The display field type. Possible values are

text

textarea

password
