thinkphp3.2.3 无法调用带下划线的模型

thinkphp 3.2.3

如果表名中带有下划线,在分割的时候命名模型类,首字母大写,例如:order_customer_bom 为表名 .模型名为OrderCustomerBomModel  
引用的时候D('OrderCustomerBom') 即可调用.




php 控制器代码如下
public function getAsinLinkPrAjax()
{
    $_POST['asin']=1;
    $map['order_customer.asin']=$_POST['asin'];

    D('OrderCustomerBom')->getAsinBomlist(123);

    $u=new \Home\Model\Order_customer_bomModel();
    $list=$u->getAsinBomlist();
    $this->ajaxReturn($list);
}

模型代码如下

class OrderCustomerBomModel extends Model
{

//查询asin下的产品清单
    public function getAsinBomlist($asin)
    {
        $map['order_customer_bom.asin']=$asin;
        $map['order_customer_bom.status']=1;
        $list=M('order_customer_bom')
            ->field('
            pid,
            namezh,
            nameus,
            thumb,
            shortname
            
            ')
            ->where($map)
            ->join('LEFT JOIN product ON order_customer_bom.pid = product.id')
            ->select();
    }
 }



真是表明如下

CREATE TABLE `order_customer_bom` (
  `id` int(11) NOT NULL,
  `asin` char(32) COLLATE utf8mb4_bin NOT NULL COMMENT 'asin',
  `type` int(8) DEFAULT NULL COMMENT '类型, 类型1 为销售订单.',
  `number` int(8) DEFAULT NULL COMMENT '数量',
  `pid` int(11) DEFAULT NULL COMMENT '产品id',
  `price` int(11) DEFAULT NULL COMMENT '单价',
  `status` int(3) DEFAULT NULL COMMENT '状态 1.生效,0初始化.2删除',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin COMMENT='销售清单表';
