在做一个订单系统,在用视图模型的时候打印不出东西。
自定义的视图模型
<?php
//订单视图
Class OrderViewModel extends ViewModel{
public $viewFields = array(
'order' => array('id','orderNo','date','money','memo','state','_type'=>'LEFT'),
'client' => array('clientName','_on'=>'order.client_id=client.id','_type'=>'RIGHT'),
'user' => array('userName','_on'=>'order.user_id=user.id'),
);
}
?>
表结构
执行了下列语句之后,打印出一片空白
$Model = D("OrderView");
$result = $Model->select();
p($result);die;
查看日志文件后,生成的SQL语句是
SELECT order.id AS id,order.orderNo AS orderNo,order.date AS date,order.money AS money,order.memo AS memo,order.state AS state,client.clientName AS clientName,user.userName AS userName FROM or_order order LEFT JOIN or_client client ON order.client_id=client.id RIGHT JOIN or_user user ON order.user_id=user.id
请各位大神帮帮忙。这是一个期末设计性实验,还有几天就要交了,万分紧急,谢谢!
------解决思路----------------------
表的别名不要用order,
order是关键字~
