I have a small misunderstanding in how the joining in Doctrine2 work. We have a pretty complex structure in our app and we are building management screens for it.
我对加入Doctrine2的工作方式有一点误解。我们的应用程序中有一个非常复杂的结构,我们正在为它构建管理屏幕。
The area of concern is as follows:
关注的领域如下:
Once of the objects 'Application' looks like this:
一旦对象'Application'看起来像这样:

}
In one of our work flows we need to join these two with bunch of additional joins and we got something like this:
在我们的一个工作流程中,我们需要将这两个连接加入一系列额外的连接,我们得到这样的结果:
$qb = $this->createQueryBuilder('e');
$qb->innerJoin('e.applicationType', 'et', Expr\Join::WITH, 'et.mobileEvent = :mobileEvent AND et.snapApp = :snapApp AND et.snapEvent = :snapEvent');
$qb->innerJoin('e.snapEventAttributes', 'attrs');
$qb->innerJoin('e.project', 'p');
$qb->innerJoin('p.applications', 'a');
$qb->innerJoin('a.applicationType', 'at', Expr\Join::WITH, 'at.mobileEvent = :vMobileEvent AND at.snapApp = :vSnapApp AND at.snapEvent = :vSnapEvent');
$qb->leftJoin('e.customer', 'cust');
$qb->leftJoin('p.partner', 'partn');
$qb->setParameters(array(
'mobileEvent' => false,
'snapApp' => false,
'snapEvent' => true,
'vMobileEvent' => false,
'vSnapApp' => true,
'vSnapEvent' => false,
));
return $qb;
All the logic works perfectly fine, however once I execute this query:
所有逻辑都可以正常工作,但是一旦我执行了这个查询:
$qb->getQuery()->getResult();
the main query is getting executed as expected but automatically doctrine executes bunch of queries to get the SnapEventAttributes objects:
主查询按预期执行,但自动doctrine执行一堆查询以获取SnapEventAttributes对象:
SELECT t0.id AS id1, t0.directSelectId AS directSelectId2, t0.description AS description3, t0.access AS access4, t0.status AS status5, t0.snapAppVersion AS snapAppVersion6, t0.pwd AS pwd7, t0.thumbnailUrl AS thumbnailUrl8, t0.location AS location9, t0.Applications_id AS Applications_id10 FROM SnapEventAttributes t0 WHERE t0.Applications_id = ?
What am I missing? What could be a reason for this behavior?
我错过了什么?这种行为可能是什么原因?
Thanks, A.

#1
get the repository
获取存储库
Controller
$snapEvents = $this->em->snapEvents ( 'Entity\SnapEventAttributes' )->findAll ();
$data ['snapEvents '] = $snapEvents ;
then on the view
然后在视图上
View
foreach ($snapEvents $sanpEvent) {
echo "<tr>".
"<td>" . $sanpEvent->getAppliction()->getApplicationType() . "</td>".
"<td>" . $sanpEvent->getAppliction()->getCutomer() . "</td>".
}
Like this keep on calling what u want since u have already joined columns at the model
像这样继续调用你想要的东西,因为你已经在模型中加入了列
