After Model inherits ActiveRecord, if you want to set default values for attributes, you can override the constructor. The code is as follows:
/**
* 构造函数
*
* @param array $config
*/
public function __construct ($config = [])
{
$this->setAttribute('is_parent', 1);
$this->setAttribute('take_rate', 0);
$this->setAttribute('show_virtual', 0);
$this->setAttribute('cat_sort', 255);
parent::__construct($config);
}
