[英]With a OneToMany relation between entities, how create the right queryBuilder with Doctrine (on the Inversed Side entity)
I have these 3 entities in my symfony2.6 project: 我的symfony2.6项目中有以下3个实体 :
Compteurs.php Compteurs.php
class Compteurs
{
/**
* @var \PointsComptage
*
* @ORM\ManyToOne(targetEntity="PointsComptage", inversedBy="compteurs")
* @ORM\JoinColumns({
* @ORM\JoinColumn(name="pointscomptage_id", referencedColumnName="id")
* })
*/
private $pointsComptage;
/**
* @var \Doctrine\Common\Collections\Collection
*
* @ORM\OneToMany(targetEntity="ParametresMesure", mappedBy="compteurs")
*/
private $parametresMesure;
ParametresMesure.php : ParametresMesure.php :
class ParametresMesure
{
/**
* @var Compteurs
*
* @ORM\ManyToOne(targetEntity="Compteurs", inversedBy="parametresMesure")
* @ORM\JoinColumn(name="compteurs_id", referencedColumnName="id")
*/
private $compteurs;
PointsComptage.php PointsComptage.php
class PointsComptage
{
/**
* @var \Doctrine\Common\Collections\Collection
*
* @ORM\OneToMany(targetEntity="Compteurs", mappedBy="pointsComptage")
*/
private $compteurs;
As you can see, the these entites are linked each other. 如您所见,这些实体相互链接。
I created a table for display all PointsComptage
and datas I need into the table. 我创建了一个表,用于显示表中所需的所有PointsComptage
和数据。 This the code for the table in my twig view: 这是我的树枝视图中表格的代码:
<tbody>
{% for currentPC in pointsComptage %}
<tr>
<td>{{ currentPC.ensembles}}</td>
<td>{{ currentPC.nomPointComptage}}</td>
<td>{{ currentPC.invariantPointComptage}}</td>
<td>{{ currentPC.typesEnergie}}</td>
<td>{{ currentPC.typesComptage}}</td>
<td>{{ currentPC.consoProduction}}</td>
<td>
<a href="{{ path('detailsPointsComptage', {'id': currentPC.id }) }}"><button class="btn btn-info btn-xs">Détail</button></a>
<a href="{{ path('modifierPointsComptage', {'id': currentPC.id }) }}"><button class="btn btn-warning btn-xs">Modifier</button></a>
</td>
</tr>
{% endfor %}
</tbody>
Of course, for now, all works well. 当然,到目前为止,一切正常。 When I click on the details button, it redirects me on a new page, where there is another table who displaying all the datas I need for the current Point Comptage I choose before ( currentPC.id
). 当我单击详细信息按钮时,它会将我重定向到一个新页面,该页面上还有另一个表,该表显示了我之前选择的当前Point Comptage ( currentPC.id
)所需的所有数据。
So this is my controller method for displaying the detail page: 这是我用于显示详细信息页面的控制器方法:
public function detailsPointsComptageAction($id)
{
$em=$this->getDoctrine()->getManager();
$detailPC = $this->getDoctrine()
->getRepository('MySpaceMyBundle:PointsComptage')
->findOneById($id);
$compteur = $this->getDoctrine()
->getRepository('MySpaceMyBundle:PointsComptage:Compteurs')
->getCompteursAttributesByPC($id);
return $this->render('MySpaceMyBundle:MyFolder:detailsPC.html.twig', array( 'detailsPC' => $detailPC, 'compteurs' => $compteur));
}
To explain briefly: I recover the id of my currentPC I cliked on for displaying his detail page, and on his detail page I need to display all compteurs associated to the currentPC and all the other attributes associated to these compteurs ( ParametreMesure.php
). 简要地解释一下:我恢复了我喜欢用来显示他的详细信息页面的currentPC的ID,并且在他的详细信息页面上,我需要显示与currentPC关联的所有组件以及与这些组件关联的所有其他属性( ParametreMesure.php
)。
So I created a queryBuilder for Compteurs , in CompteursRepository.php
, with my getCompteursAttributesByPC($id)
method ($id matches with the $id
for PointsComptage.php
). 所以,我创建了一个对的QueryBuilder Compteurs,在CompteursRepository.php
,我getCompteursAttributesByPC($id)
方法 ($ ID与匹配$id
为PointsComptage.php
)。
This is the code for: CompteursRepository.php 这是以下代码: CompteursRepository.php
public function getCompteursAttributesByPC($id)
{
$queryBuilder = $this->_em->createQueryBuilder();
$queryBuilder
->select('pm', 'c')
->from('MySpaceMyBundle:PointsComptage', 'pc')
->from('MySpaceMyBundle:ParametresMesure', 'pm')
->leftJoin('MySpaceMyBundle:Compteurs', 'c', 'WITH', 'pm.compteurs = c.id')
->where('pc.id = c.pointsComptage ')
->andWhere('pc.id = :id')
->setParameter('id', $id);
return $queryBuilder->getQuery()
->getArrayResult();
}
But I have this error with my repository method: 但是我的存储库方法出现此错误:
An exception occurred while executing 'SELECT c0_.id AS id_0, c0_.matricule_compteur AS matricule_compteur_1, c0_.mise_en_service_compteur AS mise_en_service_compteur_2, c0_.mise_hors_service_compteur AS mise_hors_service_compteur_3, p1_.id AS id_4, p1_.code_parametre AS code_parametre_5, p1_.nom_parametre AS nom_parametre_6 FROM points_comptage p2_ LEFT JOIN compteurs c0_ ON (p1_.compteurs_id = c0_.id), parametres_mesure p1_ WHERE p2_.id = c0_.pointscomptage_id AND p2_.id = ?' 执行'SELECT c0_.id AS id_0,c0_.matricule_compteur AS matricule_compteur_1,c0_.mise_en_service_compteur AS mise_en_service_compteur_2,c0_.mise_hors_service_compteur AS AS mise_hors_service_para_re_para_re_para_re_para_re_para_re_para_re_para_re_para_re_para_re_para_re_para_re_pre_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_met_me_met_met_met_met_met_met_me_met_met_met_met_met_met_me_met_met_met_met_met_met_met_met_met_met_1 p2_ LEFT JOIN compteurs c0_ ON(p1_.compteurs_id = c0_.id),parametres_mesure p1_ WHERE p2_.id = c0_.pointscomptage_id AND p2_.id =?' with params ["1"]: 带有参数[“ 1”]:

Someone could explain me how can I recover all the datas I need for the detail page and display them in my detail page? 有人可以向我解释如何恢复详细页面所需的所有数据并将其显示在详细页面中?
I hope you understand well what I am trying to do here: one PointComptage
-> all of his Compteurs
-> all of the ParametresMesure
of the Compteurs
linked to the PointComptage
I choose first. 我希望您能很好地理解我在这里要做什么: 一个 PointComptage
>他的所有Compteurs
>所有与我首先选择的Compteurs
链接的PointComptage
的ParametresMesure
。
UPDATE -EDIT 更新-编辑
I try with this query following @Jovan Perovic suggestion: 我在@Jovan Perovic建议之后尝试使用此查询:
public function getCompteursAttributesByPC($id)
{
$queryBuilder = $this->_em->createQueryBuilder();
$queryBuilder
->select('pc')
->addSelect('pm')
->addSelect('c')
->from('MySpaceMyBundle:Compteurs', 'c')
->leftJoin('c.pointsComptage', 'pc')
->join('c.parametresMesure', 'pm')
->where('c.pointsComptage = :id')
->andWhere('c.id = pm.compteurs')
->setParameter('id', $id);
return $queryBuilder->getQuery()
->getScalarResult();
}
Note that in my queryBuilder I change getArrayResult()
by getScalarresult()
, because with a var dump with getArrayResult I have this: 请注意,在我的queryBuilder中,我通过getScalarresult()
更改了getArrayResult()
,因为在使用带有getArrayResult的var dump时,我有以下内容:
array (size=2)

As you can see, there are no results for ParametresMesure. 如您所见,ParametresMesure没有结果。
And with getScalarResult() I have this: 和getScalarResult()我有这个:

The difference is that with getScalarresult() , my query recover the datas of ParametresMesure.php
linked to the Compteurs.php
whereas with getArrayResult() not. 区别在于,使用getScalarresult()时 ,我的查询将恢复链接到Compteurs.php
的ParametresMesure.php
的数据,而使用getArrayResult()则不会。
My view code and my controller code are still the same, but I have now this error: 我的视图代码和控制器代码仍然相同,但是现在出现此错误:
Key "matriculeCompteur" for array with keys "c_id, c_matriculeCompteur, c_miseEnService, c_miseHorsService, pc_id, pc_invariantPointComptage, pc_nomPointComptage, pc_codeDistribution, pc_localisationPointComptage, pm_id, pm_codeParametre, pm_nomParametre" does not exist in MySpaceMyBundle:MyFolder:detailsPC.html.twig at line 41 带有键“ c_id,c_matriculeCompteur,c_miseEnService,c_miseHorsService,pc_id,pc_invariantPointComptage,pc_nomPointComptage,pc_codeDistribution,pc_localisationPointComptage,pm_id,pm_codeParametreMySpace的MyKey的MyKey”不存在行:pm_nomParameIn:
The line 41 matches with this code: <td>{{ currentCompteur.matriculeCompteur}}</td>
第41行与此代码匹配: <td>{{ currentCompteur.matriculeCompteur}}</td>
As you can understand, matriculeCompteur
corresponds to $matriculeCompteur
in my Compteurs.php
entity. 正如你所了解, matriculeCompteur
相当于$matriculeCompteur
我Compteurs.php
实体。
This is my code for recover all datas linked to the compteurs in relation with the id of PointComptage selected before, then all ParametresMesure linked to these Compteurs: 这是我的代码,用于恢复与以前选择的PointComptage的ID有关的所有链接到Compteurs的数据,然后恢复所有链接到这些Compteurs的ParametresMesure:
<tbody>
{% for currentCompteur in compteurs %}
<tr>
<td>{{ currentCompteur.matriculeCompteur}}</td>
<td>{{ currentCompteur.miseEnService|date("Y-m-d", "Europe/Paris")}}</td>
<td>{{ currentCompteur.miseHorsService|date("Y-m-d", "Europe/Paris")}}</td>
<td class="no-cell-padding">
<table class="inner-table table stripe row-border order-column display table-bordered table-hover compact" cellspacing="0" width="100%">
<tr>
<td>code for parametresMesure</td>
<td>code for parametresMesure</td>
<td>code for parametresMesure</td>
<td>code for parametresMesure</td>
</tr>
</table>
</td>
</tr>
{% endfor %}
</tbody>
When you specify multiple FROM
s, later one will overwrite the previous ones. 当您指定多个FROM
,后一个将覆盖前一个。
So, instead of writing: 因此,与其编写:
$queryBuilder
->select('pm', 'c')
->from('MySpaceMyBundle:PointsComptage', 'pc')
->from('MySpaceMyBundle:ParametresMesure', 'pm')
->leftJoin('MySpaceMyBundle:Compteurs', 'c', 'WITH', 'pm.compteurs = c.id')
->where('pc.id = c.pointsComptage ')
->andWhere('pc.id = :id')
->setParameter('id', $id);
I believe you need something like this: 我相信您需要这样的东西:
$queryBuilder
->select('pc', 'c', 'pm')
->from('MySpaceMyBundle:PointsComptage', 'pc')
->join('pc.compteurs', 'c')
->leftJoin('c.parametresMesure', 'pm')
->where('pc.id = :id')
->setParameter('id', $id);
Since you do not have a direct link from PointsComptage
to ParametresMesure
, you first need to join PointsComptage
with Compteurs
and then Compteurs
with ParametresMesure
. 由于您没有从PointsComptage
到ParametresMesure
的直接链接, PointsComptage
首先需要将PointsComptage
与Compteurs
,然后将Compteurs
与ParametresMesure
Compteurs
。
Just note, I wrote ->join('pc.compteurs', 'c')
but based on your logic you might want to use leftJoin
instead. 只是注意,我写了->join('pc.compteurs', 'c')
但根据您的逻辑,您可能想改用leftJoin
。
Is this what you're trying to achieve? 这是您要达到的目标吗?
Hope this helps. 希望这可以帮助。
I choose @Jovan Perovic because it allowed me to find the good answer. 我选择@Jovan Perovic是因为它使我找到了很好的答案。 This is my code for the queryBuilder I made for find my results: 这是我为查找结果而创建的queryBuilder的代码:
