public static function update($data = [], $where = [])
{
$model = new static();
$result = $model->isUpdate(true)->save($data, $where);
return $model;
}自己添了个成员变量储存结果public static function update($data = [], $where = [])
{
$model = new static();
$model->result = $model->isUpdate(true)->save($data, $where);
return $model;
}
