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'], ], ]); ?> |
