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:
用gii会自动生成此代码;
第一步:
在OrderSearch添加一个$customer_name变量
第二步:
$dataProvider->setSort([
'attributes' => [
/ 其它字段不要动 /
/ 下面这段是加入的 /
/=============/
'customer_name' => [
'asc' => ['customer.customer_name' => SORT_ASC],'desc' => ['customer.customer_name' => SORT_DESC],'label' => 'Customer Name'
],/=============/
]
]);
if (!($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
