Question

I was trying to create a console command for yii 2 rbac I'm getting exception:

'yii\base\UnknownMethodException' with message 'Calling unknown method: yiibac\DbManager::getItem()'

 protected function createItem($name,$type,$description='',$data=null)
{
$item=$this->_authManager->getItem($name);
if($item===null)
{
    $item = new Item;
    $item->name = $name;
    $item->type = $type;

    self::$newCount++;
    echo "creating new item $name 
";

}
return $item;
}
