fleaphp 关联表 打印出sql 语句不对

<?php
FLEA::loadClass('FLEA_Db_TableDataGateway');
class Table_Ipromiseusers extends FLEA_Db_TableDataGateway {

  var $tableName = 'ipromise_users';
  /**
  * 指定主键字段名
  *
  * @var string
  */
  var $primaryKey = 'id';

var $hasMany = array(
  'tableClass' => 'Table_Ipromisevote',
  'mappingName' => 'id',
  'foreignKey' => 'u_id',
  );
}
?>
这是用户表关联文章表的配置

控制器里面调用
  $obj_temp = FLEA::getSingleton('Table_Ipromiseusers');
$row = array();
if(isset($_GET['u']) || !empty($u)){
$con = 'con';
$u = $_GET['u'];
$conditions = "nums like '%".$u."%'";
$pager = new Model_extPager($obj_temp, $page, 1, $conditions, $sort);
$rows = $pager->findAll();}
rows数组是两个表的数据
二现在前台怎么是一个表的sql:: SELECT `bz_ipromise_users`.`id` AS flea_pkref_id, `bz_ipromise_users`.* FROM `bz_ipromise_users`

没有关联起来，那点出错啦

帮忙啊
