YII2 SqlDataProvider doesn't work relation table value - php

Question

This is my model Riders:
<?php
namespace backend\models;
use Yii;
class Riders extends \yii\db\ActiveRecord
{
public static function tableName()
{
return 'riders';
}
public function rules()
{
return [
[['cagories_category_id', 'rider_firstname', 'rider_no_tlpn', 'rider_ucinumber', 'countries_id', 'rider_province', 'rider_city', 'rider_dateofbirth', 'rider_gender'], 'required'],
[['user_id', 'countries_id'], 'integer'],
[['rider_dateofbirth', 'cagories_category_id'], 'safe'],
[['rider_gender', 'rider_status'], 'string'],
[['rider_firstname', 'rider_lastname', 'rider_nickname', 'rider_province', 'rider_city'], 'string', 'max' => 45],
[['rider_email', 'rider_sponsor', 'rider_birthcertificate_url', 'rider_parental_consent_url'], 'string', 'max' => 100],
[['rider_no_tlpn'], 'string', 'max' => 15],
[['rider_ucinumber'], 'string', 'max' => 11]
];
}
/**
* #inheritdoc
*/
public function attributeLabels()
{
return [
'rider_id' => 'rider_id',
'cagories_category_id' => 'Category Name',
'user_id' => 'User Team',
'rider_firstname' => 'Rider Firstname',
'rider_lastname' => 'Rider Lastname',
'rider_nickname' => 'Rider Nickname',
'rider_email' => 'Rider Email',
'rider_no_tlpn' => 'Rider No Tlpn',
'rider_ucinumber' => 'Rider Ucinumber',
'countries_id' => 'Country Name',
'rider_province' => 'Rider Province',
'rider_city' => 'Rider City',
'rider_sponsor' => 'Rider Sponsor',
'rider_dateofbirth' => 'Rider Dateofbirth',
'rider_gender' => 'Rider Gender',
'rider_birthcertificate_url' => 'Rider Birthcertificate Url',
'rider_parental_consent_url' => 'Rider Parental Consent Url',
'rider_status' => 'Rider Status',
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getRegistrations()
{
return $this->hasMany(Registrations::className(), ['riders_rider_id' => 'rider_id']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getCagoriesCategory()
{
return $this->hasOne(Categories::className(), ['category_id' => 'cagories_category_id']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getUser()
{
return $this->hasOne(User::className(), ['id' => 'user_id']) -> from(user::tableName() . 'ud');
}
/**
* #return \yii\db\ActiveQuery
*/
public function getUserDesc()
{
return $this->hasOne(UserDesc::className(), ['desc_id' => 'user_id']) -> from(['ud' => userDesc::tableName()]);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getCountries()
{
return $this->hasOne(Countries::className(), ['id' => 'countries_id']);
}
}
This my Controller actionIndex:
$searchModel = new RidersSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$totalCount = Yii::$app->db->createCommand('SELECT COUNT(*) FROM riders WHERE user_id = :user_id',
[':user_id' => Yii::$app->user->identity->id])->queryScalar();
$dataProvider = new SqlDataProvider([
'sql' => 'SELECT * FROM riders WHERE user_id = :user_id',
'params' => [':user_id' => Yii::$app->user->identity->id],
'totalCount' => $totalCount,
'key' => 'rider_id',
'pagination' => [
'pageSize' => 10,
],
'sort' => [
'attributes' => [
'cagories_category_id',
'rider_id',
'rider_firstname',
'rider_email:email',
'rider_no_tlpn',
]
]
]);
$models = $dataProvider->getModels();
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
This is my view index:
<?= GridView::widget([
'dataProvider' => $dataProvider,
// 'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
[
'label' => 'Category Name',
'attribute'=>'cagories_category_id',
'value' => 'cagoriesCategory.category_name', <---Can't work again
],
[
'label' => 'BIB',
'attribute'=>'rider_id',
],
'rider_firstname',
'rider_email:email',
'rider_no_tlpn',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
Before I use sqldataprovider, it can call from model function have relation, after use sqldataprovider can't work. How to get relation table value???
then before use it, i can to merge rider_firstname and rider_lastname with return $model->rider_firstname . " " . rider_lastname; after use sqldataprovider can't work too??

Answer 1

SqlDataProvider returns data as an array so You can't able to access related object with $dataProvider->models()
either you have to use ActiveDataProvider or change your Sql of SqlDataProvider with join condition
sql='sql' => 'SELECT * FROM riders inner join '. Categories::tableName() .' as c on c.category_id=riders.cagories_category_id WHERE user_id = :user_id'
