One search form to 3 Gridview in same page - yii2

Question

Friends,
I have an INDEX page with 3 GRIDVIEW components (model Keys, model Products, model Indicators). And on that same page I have a search form with a dropdownlist (company).
I need to: When you select for example company 02 the 3 GRIDVIEW are filtered only company records 02.
_search.php
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use kartik\date\DatePicker;
?>
<div class="ideas-search">
<?php $form = ActiveForm::begin([
'options' => [
'class' => 'form-inline',
],
'action' => ['index'],
'method' => 'get',
]); ?>
<?= $form->field($model, 'pa')->dropdownList([..])?>
...
index.php
<?php echo $this->render('_search', ['model' => $searchBase]); ?>
<?php Pjax::begin(['id' => '1']) ?>
<?= GridView::widget([
'id' => 'grid1',
'dataProvider' => $dataProviderKey,
'columns' => [
...
],
]); ?>
<?php Pjax::end() ?>
<?php Pjax::begin(['id' => '2']) ?>
<?= GridView::widget([
'id' => 'grid2',
'dataProvider' => $dataProviderProduct,
'columns' => [
...
],
]); ?>
<?php Pjax::end() ?>
<?= GridView::widget([
'dataProvider' => $dataProviderIndicators,
'summary' => false,
'columns' => [
...
],
]); ?>
== UPDATE==
BaseController
public function actionIndex()
{
$searchBase = new BaseSearch();
$searchBase->pa = 0;
$searchBase->data = date("Y-m-d");
$dataProviderBase = $searchBase->search(Yii::$app->request->queryParams);
$searchMobilizadores = new MobilizadoresSearch();
$dataProviderMobilizadores = $searchMobilizadores->search(Yii::$app->request->queryParams);
$searchIndicadores = new IndicadoresSearch();
$dataProviderIndicadores = $searchIndicadores->search(Yii::$app->request->queryParams);
return $this->render('index', [
'searchBase' => $searchBase,
'dataProviderBase' => $dataProviderBase,
'searchMobilizadores' => $searchMobilizadores,
'dataProviderMobilizadores' => $dataProviderMobilizadores,
'searchIndicadores' => $searchIndicadores,
'dataProviderIndicadores' => $dataProviderIndicadores,
]);
}

Answer 1

dont forget define filterModel in your Gridview Widget
view file
GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
1st Approach :
You may use a single model that extend from model that joint all 3 table and create a search model for it. If u insist on separating all 3 table in the view, you may just declare different column for each grid.
a tip to achieve this, you may create a view and use gii tool to generate view file.
the tricky part is that 1 model can only hold one table except you joint. But, by joining table, you may get extra rows that are not necessarily needed for lets say your $dataProviderKey grid.
2nd Approach :
manually check for params from Yii::$app->request->get() add filter for each $dataprovider.
controller file
if(isset($id = Yii::$app->request->get('company_id'))) {
$dataProviderKey->query->andFilterWhere(['company.id' => $id]);
$dataProviderProduct->query->andFilterWhere(['company.id' => $id]);
$dataProviderIndicators->query->andFilterWhere(['company.id' => $id]);
}
== UPDATE ==
to answer your update question, you may assign your base search attributes to the respective attributes from others searchModel like this :
public function actionIndex()
{
$searchBase = new BaseSearch();
$searchBase->pa = 0;
$searchBase->data = date("Y-m-d");
$dataProviderBase = $searchBase->search(Yii::$app->request->queryParams);
$searchMobilizadores = new MobilizadoresSearch();
$searchMobilizadores->company = $searchBase->company; -->add this
$dataProviderMobilizadores = $searchMobilizadores->search(Yii::$app->request->queryParams);
$searchIndicadores = new IndicadoresSearch();
$searchIndicadores->company = $searchBase->company; -->add this
$dataProviderIndicadores = $searchIndicadores->search(Yii::$app->request->queryParams);
