Yii2.0框架模型多表关联查询示例

use app/models/User;$right = Right::findOne(2);//$user = User::find()->where(['right_id' => $right->attributes['id']])->all();$user = $right->hasMany(User::className(),['right_id' => 'id'])->all();//right_id为User::className()表中字段，id为Right::findOne(2)表字段

namespace app/models;use /yii/db/ActiveRecord;class Right extends ActiveRecord{  public function getUsers()  {    $users = $this->hasMany(User::className(),['right_id' => 'id'])->asArray()p->all();    return $users;  }}

public function actionAbout(){  $right = Right::findOne(2);//  $users = $right->getRights();  $users = $right->rights;  dd($users);  return $this->render('about');}

namespace app/models;use /yii/db/ActiveRecord;class User extends ActiveRecord{  public function getRight()  {    $right = $this->hasOne(Right::className,['id' => 'right_id'])->asArray();    return $right;  }}

$user = User::findOne(1);$right = $user->user;dd($right);return $this->render('about');

//查询关联表的所有数据$user = User->find()->with('right')->asArray()->all();
