情境要求:

要在订单(Order)视图的gridview中显示出客户(Customer)姓名,并使其具有与其它字段相同的排序和搜索功能。

数据库结构

订单表order含有字段customer_id 与 客户表customer的id字段关联

首先确保在Order Model中包含以下代码:

public function getCustomer(){  return $this->hasOne(Customer::className(), ['id' => 'customer_id']);}

用gii会自动生成此代码;

第一步:

在OrderSearch添加一个$customer_name变量

class OrderSearch extends Order{  public $customer_name; //<=====就是加在这里}

第二步:

修改OrderSearch中的search函数

public function search($params){  $query = Order::find();  $query->joinWith(['customer']);<=====加入这句  $dataProvider = new ActiveDataProvider([    'query' => $query,  ]);    $dataProvider->setSort([    'attributes' => [      /* 其它字段不要动 */        /* 下面这段是加入的 */      /*=============*/      'customer_name' => [        'asc' => ['customer.customer_name' => SORT_ASC],        'desc' => ['customer.customer_name' => SORT_DESC],        'label' => 'Customer Name'      ],      /*=============*/    ]  ]);   if (!($this->load($params) && $this->validate())) {    return $dataProvider;  }  $query->andFilterWhere([    'id' => $this->id,    'user_id' => $this->user_id,    'customer_id' => $this->customer_id,    'order_time' => $this->order_time,    'pay_time' => $this->pay_time,  ]);  $query->andFilterWhere(['like', 'status', $this->status]);   $query->andFilterWhere(['like', 'customer.customer_name', $this->customer_name]) ;//<=====加入这句    return $dataProvider;}

第三步:

修改order/index视图的gridview

<?= GridView::widget([  'dataProvider' => $dataProvider,  'filterModel' => $searchModel,  'columns' => [    ['class' => 'yii/grid/SerialColumn'],    'id',    'customer_id',     'status',    ['label'=>'客户', 'attribute' => 'customer_name', 'value' => 'customer.customer_name' ],//<=====加入这句    ['class' => 'yii/grid/ActionColumn'],  ],]); ?>
