model生命周期分析笔记

1. 控制器实例化userinfo；

use app\index\model\UserInfo;

class Index
{
    public function index()
    {
       $user = new UserInfo();
        //print_r($user);
        //var_dump($user->find(1));
        //print_r($user);
    }
}

初始化 model下面的__construct,

$this->autoWriteTimestamp = $this->getQuery()->getConfig('auto_timestamp');//获取时间戳，同时也将db的connection连接上
getQuery会寻找buildQuery，buildQuery创建连接
