How to pass relationship data to listview in yii2 - php

Question

im trying to print an attribite from another table in yii2 Listview but im not able to get the data i need to print into the listview
$query = Producto::find()->joinWith(['mPrecios']);
$dataProvider = new ActiveDataProvider([
'query' => $query,
'pagination' => [
'pageSize' => 6,
],
]);
Data Provider in search model
$searchModel = new ProductoSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$modelCliente=new Cliente;
$cliente = Cliente::getClientes();
$rows = Producto::autocomplete();//Se envia la variable que contiene los productos a la vista
return $this->render('index', array(
'rows'=>$rows,
'model' => $model,
'modelC'=>$modelCliente,
'searchModel' => $searchModel,
'clientes'=>$cliente,
'listDataProvider' => $dataProvider
)
);
Send DtaProvider through Controller
<?php \yii\widgets\Pjax::begin(['id'=>'listaProductos','enablePushState' => true, 'timeout' => 8000000, 'clientOptions' => ['container' => 'pjax-container']]); ?>
<?=
ListView::widget([
'options'=>[
'class'=>'col-lg-12 list-wrapper inline row-eq-height',
],
'dataProvider' => $listDataProvider,
'itemView' => function ($model, $key, $index, $widget) {
$itemContent = $this->render('_tabla_producto',['model' => $model]);
return $itemContent;
},
'itemOptions' => [
'tag' => false,
],
'summary' => '',
'layout' => '{items}{pager}',
'pager' => [
'firstPageLabel' => 'Primera',
'lastPageLabel' => 'Ultima',
'maxButtonCount' => 5,
'options' => [
'class' => ' pagination col-xs-12'
]
],
]);
?>
<?php \yii\widgets\Pjax::end(); ?>
ListView
<?php $IdProducto = $model['Refe'];?>
<div id="producto-<?php echo $IdProducto;?>" class="content inline producto col-lg-4 box-body" >

Answer 1

I will assume you have your relation set up correctly in your model, getMPrecios().
If this is a hasOne() you can access the relational data with $model->mPrecios->attributeName and if its a hasMany() you'll have to do a
foreach($model->mPrecios as $mprecios)
{
echo $mprecios->attributeName;
}
This relational values should be accessible regardless of whether you eagerly load them (like you do with a joinWith()) or lazy load them.
