搜索+ GridView（yii2）

Question

相關模型首先，我知道這裏有一個類似的問題：Filter setup for related model in GridView。我試圖遵循這一點，但這並沒有成功。

我也檢查了不同的指南如何去，但我仍然堅持。 作爲參考，我在這裏

• http://www.yiiframework.com/doc-2.0/guide-output-data-widgets.html#working-with-model-relations

• http://www.yiiframework.com/wiki/653/displaying-sorting-and-filtering-model-relations-on-a-gridview/

但是隨後這些指南，我還沒有在我看來，一個搜索場+排序功能。我用gii來創建CRUD功能。

我Manufacturers.php（模型）：

// basic model, nothing special here. 
// The following line was added to create a relation 
public function getVendor() 
{ 
    return $this->hasOne(Vendors::className(), ['vendor_id' => 'vendor_id']); 
} 

我ManufacturersSearch.php（模型）：

namespace app\models; 

use Yii; 
use yii\base\Model; 
use yii\data\ActiveDataProvider; 
use app\models\Manufacturers; 

/** 
* ManufacturersSearch represents the model behind the search form about `app\models\Manufacturers`. 
*/ 
class ManufacturersSearch extends Manufacturers 
{ 
    public $vendor; 
    /** 
    * @inheritdoc 
    */ 
    public function rules() 
    { 
     return [ 
      [['manufacturer_id', 'vendor_id'], 'integer'], 
      [['name', 'vendor'], 'safe'], 
     ]; 
    } 

    /** 
    * @inheritdoc 
    */ 
    public function scenarios() 
    { 
     // bypass scenarios() implementation in the parent class 
     return Model::scenarios(); 
    } 

    /** 
    * Creates data provider instance with search query applied 
    * 
    * @param array $params 
    * 
    * @return ActiveDataProvider 
    */ 
    public function search($params) 
    { 
     $query = Manufacturers::find(); 
     $query->joinWith("vendor"); 

     // add conditions that should always apply here 

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

     $dataProvider->sort->attributes['vendor_name'] = [ 
      // The tables are the ones our relation are configured to 
      // in my case they are prefixed with "tbl_" 
      'asc' => ['vendor.name' => SORT_ASC], 
      'desc' => ['vendor.name' => SORT_DESC], 
     ]; 

     if (!$this->load($params) && $this->validate()) { 
      // uncomment the following line if you do not want to return any records when validation fails 
      // $query->where('0=1'); 
      return $dataProvider; 
     } 

     // grid filtering conditions 
     $query->andFilterWhere([ 
      'manufacturer_id' => $this->manufacturer_id, 
      'vendor_id' => $this->vendor_id, 
     ]); 

     $query->andFilterWhere(['like', 'name', $this->name]); 
     $query->andFilterWhere(['like', 'vendor.vendor', $this->vendor]); 
     return $dataProvider; 
    } 
} 

最後我的看法文件：

<?php Pjax::begin(); ?> <?= GridView::widget([ 
    'dataProvider' => $dataProvider, 
    'filterModel' => $searchModel, 
    'columns' => [ 
     ['class' => 'yii\grid\SerialColumn'], 
     'name', 
     [ 
      'label' => 'Hauptlieferant', 
      'value' => 'vendor.name', 
     ], 
     ['class' => 'yii\grid\ActionColumn'], 
    ], 
]); ?> 
<?php Pjax::end(); ?></div> 

這是我的電流輸出：

因此，它是有點兒工作，因爲替代的ID，我得到的名稱（這是我想要的東西）。但由於某些原因，這些字段不可排序也不可搜索。

表「製造商」 以及表「供應商」有一欄「名」

感謝在正確的方向上沒有任何提示。

在ManufactuiresSearch還需要joinWith過濾器

$query->andFilterWhere(['like', 'name', $this->name]); 

    $query->joinWith(['vendor' => function ($q) { 
     $q->andFilterWhere(['like', 'vendor.vendor', $this->vendor]); 
    }]); 

    return $dataProvider;
