Question

我试图从yii2 Listview中的另一个表中打印一个attribite，但我无法获取需要打印到listview中的数据

   $query = Producto::find()->joinWith(['mPrecios']);


    $dataProvider = new ActiveDataProvider([
        'query' => $query,
        'pagination' => [
            'pageSize' => 6,
        ],
    ]);

搜索模型中的数据提供者

    $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
                                                )
                                );

通过Controller发送DtaProvider

   <?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(); ?>

的ListView

     <?php $IdProducto = $model['Refe'];?>
     <div id="producto-<?php echo $IdProducto;?>" class="content inline producto col-lg-4 box-body" >
           <div class="row">

                 <?php
                    if($model['Fraccion'] > 1){
                      echo "<button id='fraccion-$IdProducto' class='btn btn-danger btn-xs fraccionado' data-toggle='modal' data-target='#modalFraccion'><b>F</b></button>";
                    }
                    else{
                      echo "<button id='fraccion-$IdProducto' class='btn btn-default btn-xs disabled'><b>NF</b></button>";
                    }
                  ?><br>

Answer 1

我假设您在模型中正确设置了关系，getMPrecios（）。

如果这是一个hasOne（），您可以使用$model->mPrecios->attributeName访问关系数据，如果它是hasMany（），则您必须执行

foreach($model->mPrecios as $mprecios)
{
    echo $mprecios->attributeName;
}

无论您是否急切地加载它们（如使用joinWith（））或延迟加载它们，都应该可以访问此关系值。

如何在yii2中将关系数据传递给listview
