Yii2 gridview中的不同行

Question

我无法在网格视图中获得唯一结果。

我迄今所做的是：

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

结果就是我想要的东西，但网格视图没有显示所有其他列比some-column，

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需的所有其他colums喜欢的名称，说明等

我更新查询如下：

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

结果不是由some_column独特。

控制器代码：

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

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

而且观点是：

GridView::widget(['dataProvider' => $dataProvider, 
           'filterModel' => $searchModel, 
           'columns'  => [['class' => 'yii\grid\SerialColumn'], 
                ['attribute' => 'Image', 
                'format' => 'html', 
                'value'  => function ($data) { 
                 return Html::img($data->image, ['width' => '100']); 
                },], 
                ['attribute'  => 'name', 
                'format'   => 'raw', 
                'value'   => function ($data) { 
                 return strlen($data->name) > 25 ? 
                  html_entity_decode(substr($data->name, 0, 25) . '...') : 
                  html_entity_decode($data->name); 
                }, 
                'contentOptions' => ['style' => 'max-width: 200px;']], 
                ['attribute'  => 'description', 
                'format'   => 'raw', 
                'value'   => function ($data) { 
                 return strlen($data->description) > 25 ? 
                  html_entity_decode(substr($data->description, 0, 25) . '...') : 
                  html_entity_decode($data->description); 
                }, 
                'contentOptions' => ['style' => 'max-width: 200px;']], 
                ['attribute' => 'price', 
                'format' => 'text', 
                'value'  => function ($data) { 
                 return html_entity_decode($data->price); 
                },], 

                ['attribute'  => 'price_category', 
                'format'   => 'text', 
                'value'   => function ($data) { 
                 return strip_tags(html_entity_decode($data->price_category)); 
                }, 
                'contentOptions' => ['style' => 'max-width: 100px;']], 
                ['attribute'  => 'product_category', 
                'format'   => 'text',

                'value'   => function ($data) { 
                 return strlen($data->product_category) > 25 ? 
                  html_entity_decode(substr($data->product_category, 0, 25) . '...') : 
                  html_entity_decode($data->product_category); 
                },

任何帮助将不胜感激。

Answer 1

结果由你选择（而不是只由some_column）

在这种情况下$query = Products::find()->select('other_columns,some_column')->distinct();由other_columns, some_column提供列的组合distinc -

您可以使用此

检查真正执行查询

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

然后将查询应该是

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

但如果你只需要一个行你shuld通过不明显

$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']);
