thinkphp视图模型查询提示ERR: 1146:Table 'db.pr_order_view' doesn't exist的解决方法,vieworder
本文实例讲述了thinkphp视图模型查询失败提示:ERR: 1146:Table 'db.pr_order_view' doesn't exist解决办法。分享给大家供大家参考。具体方法如下:
一、问题描述:
想用thinkphp的视图模型进行关联查询,结果出现了这样的问题(log日志记录):ERR: 1146:Table 'db.pr_order_view' doesn't exist,我就纳闷,视图模型怎么出来的sql是这样的呢,视图模型如下:
复制代码 代码如下:
class OrderViewModel extends ViewModel
{
public $viewFields = array(
'Order' =>array(
'_as'=>'Orders', //重新命名,以免与系统语法冲突
'id'=>'oid',
'ordid',
'user',
'product',
'status',
'paynum',
'cat',
'payment_trade_no',
'ip'=>'mip',
'reserve_time',
'createtime',
'payment_trade_status',
),
'Member'=>array(
'id'=>'mid',
'name'=>'uname',
'cardnum',
'tel',
'reg_time',
'reg_ip',
'qq',
'email',
'address',
'last_login_time',
'last_login_ip',
'_on'=>'Orders.user=Member.id'
),
'Product'=>array(
'id',
'shorttitle',
'img1',
'category',
'_on'=>'Orders.product=Product.id'
),
);
}
?>
二、解决方法:
看了手册及百度了很多,没有找到解决方案,调用也没有错$Form = D('Admin/OrderView');(这里我用了分组)经过我自己查看,原来是有问题的,原来视图模型的名字命名错了,OrderView.class.php,正常应该是 OrderViewModel.class.php。
对于ThinkPHP初学者来说尤其要注意不要犯这样的低级错误!
希望本文所述对大家的ThinkPHP框架程序设计有所帮助。
连接不建议做聚合操作,很容易出问题,一般这种都直接同步用户的消费金额,换句话说,就是再单独一份用户消费表,用户有消费的时候就增加这个字段的值。
或者把你的sql客房订单和餐饮订单分开写,不然就只有嵌套了,似乎没有这个必要
你传的是“RJ1”,M(“RJ1”)这个M方法内传的是类名,thinkphp在查询时会将类名转换为表名。归则是表前缀+_大写字母与小写字
母+_大写字母与小写字母,例如AbcDef转换为表名就是caiyy_abc_def,如果换为小写就没问题了action="/Index
/addsoft/rj1",程序还有一点错误:
$Form =M($soft);$Form->create();
这里应该是D($soft);只有D函数创建的对象有create方法.

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted.

Redis memory fragmentation refers to the existence of small free areas in the allocated memory that cannot be reassigned. Coping strategies include: Restart Redis: completely clear the memory, but interrupt service. Optimize data structures: Use a structure that is more suitable for Redis to reduce the number of memory allocations and releases. Adjust configuration parameters: Use the policy to eliminate the least recently used key-value pairs. Use persistence mechanism: Back up data regularly and restart Redis to clean up fragments. Monitor memory usage: Discover problems in a timely manner and take measures.
