Mysql query in activerecord in yii2 - yii2

Question

I have following mysql query that I need to use in yii2 -
select tsell.district,tsell.totalsale as sell,coalesce(tcollection.collection,0) as collection from(SELECT district, coalesce(sell.sale,0) as totalsale FROM `districts` left join (SELECT parties_district, billdate,sum(billamount) as sale FROM `bills` left join parties on bills.bills_partyname = parties.parties_partyname group by parties_district) as sell on sell.parties_district = districts.district) as tsell left join (SELECT parties_district,payment_date,COALESCE(sum(payment_amount),0) as collection FROM `payment` left join parties on payment.payment_partyname = parties.parties_partyname group by parties_district) as tcollection on tsell.district = tcollection.parties_district
My search model is
<?php
namespace frontend\modules\districtreport\models;
use Yii;
use yii\base\Model;
use yii\data\ActiveDataProvider;
use frontend\modules\districtreport\models\Parties;
use frontend\modules\districtreport\models\Bills;
use frontend\modules\districtreport\models\Payment;
use yii\db\Query;
use yii\db\Command;
$query = \Yii::$app->db;
/**
* PartiesSearch represents the model behind the search form about `frontend\modules\districtreport\models\Parties`.
*/
class PartiesSearch extends Parties
{
public $bills;
public $district;
public $sale;
public $sell;
public $collection;
/**
* #inheritdoc
*/
public function rules()
{
return [
[['party_id'], 'integer'],
[['parties_partyname', 'address', 'parties_district', 'name_manager', 'transport', 'dlno', 'instruction', 'con', 'district','sale','sell','collection'], 'safe'],
];
}
/**

public function scenarios()
{
// bypass scenarios() implementation in the parent class
return Model::scenarios();
}
/**

$sql = 'select tsell.district,tsell.totalsale as sell,coalesce(tcollection.collection,0) as collection from(SELECT district, coalesce(sell.sale,0) as totalsale FROM `districts` left join (SELECT parties_district, billdate,sum(billamount) as sale FROM `bills` left join parties on bills.bills_partyname = parties.parties_partyname group by parties_district) as sell on sell.parties_district = districts.district) as tsell left join (SELECT parties_district,payment_date,COALESCE(sum(payment_amount),0) as collection FROM `payment` left join parties on payment.payment_partyname = parties.parties_partyname group by parties_district) as tcollection on tsell.district = tcollection.parties_district';
$query = Parties::findBySql($sql);
// add conditions that should always apply here

$dataProvider->sort->attributes['sell'] = [

$this->load($params);
if (!$this->validate()) {
// uncomment the following line if you do not want to return any records when validation fails
// $query->where('0=1');
return $dataProvider;
}
// grid filtering conditions
$query->andFilterWhere([
'party_id' => $this->party_id,
]);
$query->andFilterWhere(['like', 'parties_partyname', $this->parties_partyname])
->andFilterWhere(['like', 'address', $this->address])

->andFilterWhere(['like', 'sell', $this->sell])
->andFilterWhere(['like', 'collection', $this->collection])
->andFilterWhere(['like', 'district', $this->district]);
return $dataProvider;
}
}
But the problem is that I am unable to sort or filter the columns. So I want to use activerecord to run the query instead of findbysql. Please help me to build this query in activerecord.
My index.php file looks like -
<?php
use yii\helpers\Html;
use yii\grid\GridView;
//use kartik\widgets\DatePicker;
use kartik\daterange\DateRangePicker;
use kartik\form\ActiveForm;
use dosamigos\datepicker\DatePicker;
/* #var $this yii\web\View */
/* #var $searchModel frontend\modules\districtreport\models\PartiesSearch */
/* #var $dataProvider yii\data\ActiveDataProvider */
$this->title = 'Parties';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="parties-index">
<h1><?= Html::encode($this->title) ?></h1>
<?php // echo $this->render('_search', ['model' => $searchModel]); ?>
<!-- <p>
<?= Html::a('Create Parties', ['create'], ['class' => 'btn btn-success']) ?>
</p> -->
<!-- <div class="custom-filter">
Date range:
<input name="start" />
<input name="end" />
</div> -->
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'district',
'sell',
'collection',
//['class' => 'yii\grid\ActionColumn'],
],
]); ?>
</div>
Here's my PartiesController.php
<?php

}

public function actionIndex()
{
$searchModel = new PartiesSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);

Answer 1

Pls have a look
$dataProvider = new SqlDataProvider([
'sql' => 'SELECT Name, Title, COUNT(ArticleTags.ID) AS TagCount ' .
'FROM Authors ' .
'INNER JOIN Articles ON (Authors.ID = Articles.AuthorID) ' .
'INNER JOIN ArticleTags ON (Articles.ID = ArticleTags.ID) ' .
'WHERE Name=:author' .
'GROUP BY ArticleID',
'params' => [':author' => 'Arno Slatius'],
]);

Answer 2

In query you missing a district alias
select
tsell.district as district,
tsell.totalsale as sell,
coalesce(tcollection.collection,0) as collection
from
(SELECT
district,
coalesce(sell.sale,0) as totalsale
FROM `districts`
left join
(SELECT
parties_district,
billdate,
sum(billamount) as sale
FROM `bills`
left join parties on bills.bills_partyname = parties.parties_partyname
group by parties_district) as sell
on sell.parties_district = districts.district) as tsell
left join
(SELECT
parties_district,
payment_date,
COALESCE(sum(payment_amount),0) as collection
FROM `payment`
left join parties on payment.payment_partyname = parties.parties_partyname
group by parties_district) as tcollection
on tsell.district = tcollection.parties_district
For sort i suggest you this notation
$dataProvider->setSort([
'attributes' => [
'sell' => [
'asc' => ['tsell.sell' => SORT_ASC],
'desc' => ['tsell.sell' => SORT_DESC],
'label' => 'Sell'
],
'collection' => [
'asc' => ['collection' => SORT_ASC],
'desc' => ['collection' => SORT_DESC],
'label' => 'Collection'
]
'district' => [
'asc' => ['tsell.district' => SORT_ASC],
'desc' => ['tsell.district' => SORT_DESC],
'label' => 'District'
]
]
]);
Be sure you have declare the vars $bills, $district, $sale, $sell, $collection only in one model class.
If you use these vars in several extended searchModel then declare only in model
otherwise declare only in the searhModel ..
Never declare in both the same var one override the others and mismatch when used by model or modelSearch function ..
