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:
1
2
3
4
|
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
1
2
3
4
|
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' ],
],
]); ?>
