Revision

The Lavalite model is capable of recording the history of changes in values by storing revisions.

The revisions can be stored for the model, you could further apply the Litepie\Rivision\Traits\Revision trait and declare a $revision property with an array containing the attributes to monitor for changes.

You also need to define a $morphMany model relation called revision_history that refers to the Litepie\Revision\Models\Revision class with the name revision, this is where the revision history data is stored.

<?

class User extends Model
{
    use \Litepie\Rivision\Traits\Revision;

    /**
     * @var array Monitor these attributes for changes.
     */
    protected $revision = ['name', 'email'];

    /**
     * @var array Relations
     */
    public $morphMany = [
        'revision_history' => ['Litepie\Revision\Models\Revision', 'name' => 'revision']
    ];
}

By default 500 records will be kept, however this limit can be further modified by declaring a $revisionableLimit property on the model with a new limit value.

<?

/**
 * @var int Maximum number of revision records to keep.
 */
public $revisionLimit = 50;

The revision history can be accessed like any other relation:

<?

$history = User::find(1)->revision_history;

foreach ($history as $record) {
    echo $record->field . ' updated ';
    echo 'from ' . $record->old_value;
    echo 'to ' . $record->new_value;
}
