PublishableBehavior allows the use of datetime fields for start and end ranges on content. Included functionality allows for checking published status, toggling to published / unpublished status, and adding conditions to a find to properly filter those results.
In order to use Publishable you only need to add to columns to your table. A datetime field for starting publishing and a datetime field for ending it. These default to 'begin_publishing' and 'end_publishing' but you can set them to anything you like. These columns also must be nullable.
Apply the behavior to your model like so:
Or, if you would like to specify your columns:
var $actsAs = array(
'Publishable' => array(
'start_column' => 'start_datetime_column',
'end_column' => 'end_datetime_column'
The Behavior checks to make sure the required columns are present when initializing and will trigger an error if they cannot be found.
With the Behavior applied, you'll now have access to these functions:
isPublished($id = '') - Returns true or false based on the published status of the record. If $id is not passed, will attempt to use $model->id
publish($id = array()) - Can either take a single id, a list of ids, or no id to attempt to use $model->id. This will set the published status of the record(s) to a start time of now and a null end time.
unpublish($id = array()) - Can either take a single id, a list of ids, or no id to attempt to use $model->id. This will set the published status of the record(s) to a start time of null and an end time of null.
publishConditions($published = true) - Returns a conditions array used to retrieve published or unpublished records that can be used in your own queries / model relationships.
No records are automatically filtered though. If you'd like to retrieve only published records from a query, simply add 'published' => true to the find options, like so:
$this->SomeModel->find('all',array('published' => true));
