当我的查询从两个或多个表中选择多个列时,如何使用 Doctrine_Pager 或 sfDoctrinePager 实现分页?
编辑1:
好的,现在我发现可以按照 Nathan 的描述来完成!我很困惑,因为我无法从查询中检索某些数据!让我在下面描述它:
这是我的寻呼机查询:
$pager = new sfDoctrinePager('sfGuardUser', '5');
$q = Doctrine_Query::create()
->select('u.id, u.username, p.org_name, g.name, l.status')
->from('sfGuardUser u')
->leftJoin('u.Profile p')
->leftJoin('u.Groups g')
->leftJoin('u.LicensedVendors l')
->where('g.name = \'client\'');
$pager->setQuery($q);
$pager->setPage($request->getParameter('page', 1));
$pager->init();
现在在我的模板中,我可以像这样检索我的 sfGuardUser 和 Profile 数据:
foreach ($pager->getResults() as $data) {
echo $data->username ; //outputs 'username' from sfGuardUser table
echo '<br />' ;
echo $data->Profile->org_name ; //outputs 'Organization name' from sfGuardUserProfile table
}
我错误地试图通过$data->org_name
而不是检索配置文件数据$data->Profile->org_name
!现在它可以正确地为这部分工作,但仍然存在问题!
我仍然无法使用或检索Groups & LicensedVendors数据!它也没有显示任何错误或任何值!看起来它输出一个空字符串。它不应该像 Profile data 一样获得价值吗?但是当我通过设置查询时:$data->Groups->name
$data->LicensedVendors->status
hydrate
$q->setHydrationMode(Doctrine_Core::HYDRATE_SCALAR);
我可以通过以下方式检索所有数据:
foreach ($pager->getResults() as $data) {
echo $data['u_username'];
echo $data['p_org_name'];
echo $data['g_name'];
echo $data['l_status'];
}
如何在不设置的情况下获取这些数据**Doctrine_Core::HYDRATE_SCALAR**
?我在检索那些Groups和LicensedVendors表数据时做错了什么?
这是上述表的架构定义:
