我目前正在构建一个查询,以便在所需日期之间返回一组记录:
public function findBetweenDates(\Datetime $date1,\Datetime $date2)
{
$date1=$date1->setTime(07,00,00);
date_modify($date2,'+1 day');
$date2->setTime(06,59,00);
$qb = $this->getEntityManager()->createQueryBuilder()
->select('e')
->from("AppBundle:Movimento","e")
->andWhere('e.pesagem1 BETWEEN :from AND :to')
->setParameter('from', $date1 )
->setParameter('to', $date2)
->orderBy('e.id','DESC')
;
$result = $qb->getQuery()->getResult();
return $result;
}
类Movimento有一些ManyToOne连接,如下所示:
class Movimento
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\ManyToOne(targetEntity="Service")
* @ORM\JoinColumn(name="service", referencedColumnName="id")
**/
private $service;
当我拿到记录并用树枝渲染时:
{% for item in items %}
<tr>
<td>{{ item.id }} </td>
<td>{{ item.service.name }}</td>
//#MORE CODE BELOW //
通过从另一个实体调用servico.name,我得到大量非需要的查询,以显示服务的名称而不是其id。 我们正在讨论每个响应中6k记录范围内的内容。
我想要一些帮助,如果可以使用我的查询构建器优化此查询,或者我应该将整个查询重新编写为&#34; SQL&#34;例如:
Select a.name, b.id
From service as a, movimento as b
Between bla bla bla
非常感谢任何帮助/建议。
编辑1 我在阅读此帖Symfony 2/Doctrine: How to lower the num of queries without losing the benefit of ORM?
后更改了我的查询构建器我确实减少了175个查询到一个
$qb = $this->createQueryBuilder('e')
->addSelect('service')->join('e.service','service')
->addSelect('motorista')->join('e.motorista','motorista')
->addSelect('residuo')->join('e.residuo','residuo')
// ->from("AppBundle:Movimento","e")
->andWhere('e.pesagem1 BETWEEN :from AND :to')
->setParameter('from', $date1 )
->setParameter('to', $date2)
->orderBy('e.id','DESC')
但是页面加载大约需要8秒(其6900条记录),在检查性能后,我的新查询的响应时间是177.79毫秒,但是我的树枝+控制器正在显示剩余的7.x秒,因为它显示了pic 我的控制器非常简单
public function getMovimentosAction(Request $request)
{
$startDate = $request->request->get('startDate');
$endDate = $request->request->get('endDate');
if (empty($startDate))
$startDate = date("Y-m-d") ;
if (empty($endDate))
$endDate = date("Y-m-d");
$em=$this->getDoctrine()->getRepository('AppBundle:Movimento');
$dados=$em->findBetweenDates(new \DateTime($startDate),new \DateTime($endDate));
return $this->render('AppBundle:Movimentos:logtable-movimento.html.twig', array(
'items' => $dados
));
}
并且我的树枝只是遍历行并将它们显示在桌子上,因为我给出了上面的部分示例。
非常感谢任何帮助/建议。
EDIT2 我的视图由ajax传递,呈现为datatable.js
<table id="example" class="table table-striped table-bordered table-hover" cellspacing="0" width="100%">

和我的HTML
$("#submitButtonQuery").click(function(event){
event.preventDefault();
var l = Ladda.create(this);
l.toggle();
$.post( "/movimentos/getList",
$( "#formAjaxify" ).serialize())
.done(function(data)
{
$('#example').remove();
$("#tabelaLog").html(data);
oTable=$('#example').DataTable(

oTable.order( [ 0, 'desc' ] )

.always(function(){

});
答案 0 :(得分:0)
只要你在&#39; Movimento&#39;之间有联系。和&#39;服务&#39;然后为每个&#39; movimento&#39;你得到的服务&#39;将被序列化。这意味着,如果您的查询返回100&#39; movimento&#39;然后与所有人一起服务&#39;将需要提取对象(100)。
如果您不希望将服务作为每个项目中的对象(AKA item.service.blahblah),那么您需要更直接的查询。
如果您使用查询构建器执行此操作,则需要以下内容:
$repository = $this->getDoctrine()
->getRepository('YourownBundle:Movimento'); //the main repo from which to get data
$query = $repository->createQueryBuilder('m') // query builder on repo
->join('m.service', 's') // join the second object to select from
->select('m.id') // select everything from m objet
->addSelect('s.name') // select everything from service (s) object
->where('e.pesagem1 BETWEEN :from AND :to')
->setParameter('from', $date1 )
->setParameter('to', $date2)
->orderBy('e.id','DESC')
你的代码的其余部分应该是你拥有的......但是你没有序列化的对象,只有你做的选择(例如.m.id,s.name)
