yii2 - get name instead of id from database - yii2

Question

Sorry im newbie for framework
i've seen many tutorials from Doingiteasy youtube channel and stuck in this
i want an example to change the id_status to become 'infostatus'.
i heard in the videos, to change id to name, i have to use relation. where can i find that?
this is my view index
<?php
use yii\helpers\Html;
use yii\grid\GridView;
/* #var $this yii\web\View */
/* #var $searchModel app\models\ReservasiSearch */
/* #var $dataProvider yii\data\ActiveDataProvider */
$this->title = 'Reservasis';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="reservasi-index">
<h1><?= Html::encode($this->title) ?></h1>
<?php // echo $this->render('_search', ['model' => $searchModel]); ?>
<p>
<?= Html::a('Create Reservasi', ['create'], ['class' => 'btn btn-success']) ?>
</p>
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id_reservasi',
'id_paket',
**'id_status',**
'id_jadwal',
'id',
// 'tanggalreservasi',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
</div>
this is my model from reservasi
<?php
namespace app\models;
use Yii;
/**
* This is the model class for table "reservasi".
*
* #property string $id_reservasi
* #property string $id_paket
* #property integer $id_status
* #property string $id_jadwal
* #property string $id
* #property string $tanggalreservasi
*
* #property User $id0
* #property Jadwal $idJadwal
* #property Paket $idPaket
* #property Status $idStatus
*/
class Reservasi extends \yii\db\ActiveRecord
{
/**
* #inheritdoc
*/
public static function tableName()
{
return 'reservasi';
}
/**
* #inheritdoc
*/
public function rules()
{
return [
[['id_reservasi', 'tanggalreservasi'], 'required'],
[['id_status'], 'integer'],
[['tanggalreservasi'], 'safe'],
[['id_reservasi'], 'string', 'max' => 15],
[['id_paket'], 'string', 'max' => 5],
[['id_jadwal'], 'string', 'max' => 4],
[['id'], 'string', 'max' => 6],
[['id'], 'exist', 'skipOnError' => true, 'targetClass' => Users::className(), 'targetAttribute' => ['id' => 'id']],
[['id_jadwal'], 'exist', 'skipOnError' => true, 'targetClass' => Jadwal::className(), 'targetAttribute' => ['id_jadwal' => 'id_jadwal']],
[['id_paket'], 'exist', 'skipOnError' => true, 'targetClass' => Paket::className(), 'targetAttribute' => ['id_paket' => 'id_paket']],
[['id_status'], 'exist', 'skipOnError' => true, 'targetClass' => Status::className(), 'targetAttribute' => ['id_status' => 'id_status']],
];
}
/**
* #inheritdoc
*/
public function attributeLabels()
{
return [
'id_reservasi' => 'Id Reservasi',
'id_paket' => 'Id Paket',
'id_status' => 'Id Status',
'id_jadwal' => 'Id Jadwal',
'id' => 'ID',
'tanggalreservasi' => 'Tanggalreservasi',
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getId0()
{
return $this->hasOne(Users::className(), ['id' => 'id']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getIdJadwal()
{
return $this->hasOne(Jadwal::className(), ['id_jadwal' => 'id_jadwal']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getIdPaket()
{
return $this->hasOne(Paket::className(), ['id_paket' => 'id_paket']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getIdStatus()
{
return $this->hasOne(Status::className(), ['id_status' => 'id_status']);
}
}
and this is from model Status
<?php
namespace app\models;
use Yii;
/**
* This is the model class for table "status".
*
* #property integer $id_status
* #property string $infostatus
*
* #property Reservasi[] $reservasis
*/
class Status extends \yii\db\ActiveRecord
{
/**
* #inheritdoc
*/
public static function tableName()
{
return 'status';
}
/**
* #inheritdoc
*/
public function rules()
{
return [
[['id_status'], 'required'],
[['id_status'], 'integer'],
[['infostatus'], 'string', 'max' => 20],
];
}
/**
* #inheritdoc
*/
public function attributeLabels()
{
return [
'id_status' => 'Id Status',
'infostatus' => 'Infostatus',
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getReservasis()
{
return $this->hasMany(Reservasi::className(), ['id_status' => 'id_status']);
}
}

Answer 1

you could add a relation to your Reservasi model for get the infostatus
Assuming you have a model named Status that contain the fields id and infostatus
/* ActiveRelation */
public function getInfostatus()
{
return $this->hasOne(Status::className(), ['id' => 'id_status']);
}
then you could refer to
$model->infostatus; // for get the value
