Yii2 gridview中的不同行

Question

我无法在网格视图中获得唯一结果。

到目前为止，我所做的是：

$query = Products::find()->select('id_product_provider')->distinct();
$dataProvider = new ActiveDataProvider([
        'query'      => $query,
        'pagination' => [
            'pageSize' => 100
        ]
    ]);

结果是我想要的，但网格视图没有显示除some-column之外的所有其他列，

输出： 我不知道，结果是我想成为的。但是网格视图没有显示所有其他所需的列，如名称，描述等。

我将查询更新为以下内容：

$query = Products::find()->select('other_columns,some_column')->distinct();

结果不是some_column唯一的。

控制器代码：

$searchModel  = new ProductsSearch();
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

        return $this->render('index', [
            'searchModel'  => $searchModel,
            'dataProvider' => $dataProvider,
        ]);

观点是：

GridView::widget(['dataProvider' => $dataProvider,
                               'filterModel'  => $searchModel,
                               'columns'      => [['class' => 'yii\grid\SerialColumn'],
                                                  ['attribute' => 'Image',
                                                   'format'    => 'html',
                                                   'value'     => function ($data) {
                                                       return Html::img($data->image, ['width' => '100']);
                                                   },],
                                                  ['attribute'      => 'name',

任何帮助将不胜感激。

Answer 1

结果是你在select中提供的列的组合（而不仅仅是some_column）

在这种情况下$query = Products::find()->select('other_columns,some_column')->distinct(); other_columns, some_column -

您可以使用此

检查真正执行的查询

  var_dump(Products::find()->select('other_columns,some_column')->distinct()
      ->createCommand()->getSql());

那么你的查询应该是

$query = Products::find()->
     select('name,  description, price, price_category')->distinct();

但是如果你只需要一行，你可以使用聚合函数，而不是使用不同的

$query = Products::find()->
     select('max(name) as name,  
          max(description) as description,
          max(price) as price, 
          max(price_category) as price_category ')->groupBy(['id_product_provider']);
