如何使用从多个表中选择不同列的原则或symfony寻呼机?
当我的查询从两个或多个表中选择多列时,如何使用 Doctrine_Pager 或 sfDoctrinePager 实现分页?
Edit1:
好的,现在我明白了这可以按照内森下面描述的方式完成!我很困惑,因为我无法从查询中检索某些数据!让我在下面描述一下:
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));
$pager->init();
现在在我的模板中,我可以像这样检索我的 sfGuardUser 和配置文件数据:
foreach ($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
}
我错误地尝试通过 $data->org_name
检索配置文件数据而不是 $data->Profile->org_name
!现在这部分工作正常,但仍然存在问题!
我仍然无法检索群组 &使用 $data->Groups->name
或 $data->LicensedVendors->status
的 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 一样获取值吗? 但是,当我通过设置Hydrate
查询时:
$q->setHydrationMode(Doctrine_Core::HYDRATE_SCALAR);
我可以通过以下方式检索所有数据:
foreach ($pager->getResults() as $data) {
echo $data['u_username'];
echo $data['p_org_name'];
echo $data['g_name'];
echo $data['l_status'];
}
如何获取这些数据数据而不设置 **Doctrine_Core::HYDRATE_SCALAR**
?我在检索这些Groups和LicensedVendors表数据时做错了什么?
以下是上述表的架构定义:

编辑2:我发布了我的新问题,我在第一次编辑中将其描述为一个单独的问题这里!
How can I implement pagination using Doctrine_Pager or sfDoctrinePager while my query selects multiple columns from two or more tables ?
Edit1:
Ok, now I figured out that it can be done how Nathan has described below! I got confused as I couldn't retrieve certain data from the query! Let me describe it below:
This is my pager query:
$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));
$pager->init();
Now in my Template I can retrieve my sfGuardUser and Profile data like this:
foreach ($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
}
I was wrongly trying to retrieve the profile data by $data->org_name
and not $data->Profile->org_name
! Now its working for this part correctly, but there is still an issue !
I am still unable to retrieve the Groups & LicensedVendors data using $data->Groups->name
or $data->LicensedVendors->status
! It does not show any error or any value either! looks like it outputs an empty string. Shouldn't it get the value just like Profile data ?
But when I hydrate
the query by setting:
$q->setHydrationMode(Doctrine_Core::HYDRATE_SCALAR);
I can retrieve all data through:
foreach ($pager->getResults() as $data) {
echo $data['u_username'];
echo $data['p_org_name'];
echo $data['g_name'];
echo $data['l_status'];
}
How to get those data without setting **Doctrine_Core::HYDRATE_SCALAR**
? Where I'm doing wrong for retrieving those Groups and LicensedVendors table data?
Here is the schema definition of the tables described above:

我想只要你的查询返回一个 Doctrine_Collection 对象,你就可以将它与寻呼机一起使用,不是吗?
I guess as long as your query gives back a Doctrine_Collection object, you can use it with a pager, can't you?
是的,greg0ire 说的。 此文档有点旧,但它显示了您的内容过去需要 Propel。更新到 Doctrine 就像,
这篇博文“两个表的 Symfony 学说寻呼机” 有一个更扩展/复杂的示例。哦,看起来这是作者对他自己的问题的回答。
Yeah, what greg0ire said. This documentation is a bit old, but it shows what you'd need with Propel in the old days. Updating to Doctrine would be like,
This blog post, "Symfony doctrine pager for two tables" has a more extended/convoluted example. Oh, looks like that was the author's answer to his own SO question.
