hasOne一对多关系，比如是吧。一个人有很多文章.
第二步：user:gii自动生成 models:
代码语言：javascript复制<?php
namespace frontendmodels;
use yiidbActiveRecord;
use frontendmodelsUser;
class Article extends ActiveRecord
{
public function getUserinfo()
{
return $this->hasOne(User::className(),['aid'=>'id']);
}
}控制器：
代码语言：javascript复制<?php
namespace frontendcontrollers;
use frontendmodelsArticle;
use frontendmodelsUser;
class IndexController extends yiiwebController
{
public function actionIndex()
{
$article=Article::findOne(['id'=>2]);
var_dump($article->userinfo);
}}
