我有多个实体,当我执行findAll时,一个实体上只有1个请求
/**
* @ORM\Entity(repositoryClass="App\Repository\PropertyRepository")
* @ORM\Table(name="property")
*/
class Property
{
/**

private $zipCode;
/**

private $country;

private $equipment;
/**

private $lessees;

我不向您显示getter / setter,因为它超过500行,但是我生成了它们。
Doctrine对每个属性进行1个查询。为了解决我的问题,我尝试这样做:
/**
* @param User $user
* @return array
*/
public function findPropertyByUser(User $user): array
{
$qb = $this->createQueryBuilder('p')
->andWhere('p.userProperty = :user')
->setParameter('user', $user)
->orderBy('p.id', 'ASC')
->getQuery();
return $qb->execute();
}
但是它没有任何改变,我也尝试使用findBy,但是它没有任何改变。谁能告诉我我的问题来自哪里?
编辑: 根据评论,这可能是n + 1问题,
我尝试了不同的方法,但是没有找到解决方案,这是我的实际方法:
/**
* @param User $user
* @return array
*/
public function findPropertyByUser(User $user): array
{
$qb = $this->createQueryBuilder('p')
->andWhere('p.userProperty = :user')
->setParameter('user', $user)
->orderBy('p.id', 'ASC')
->innerJoin('p.userProperty', 'u')
->addSelect('u')
->getQuery();
return $qb->execute();
}
我认为是最后个请求
{% if properties is defined %}
{% for property in properties %}
{% set emails = [property.userProperty.email] %}
{% for lessee in property.lessees.values %}
{% set emails = emails|merge([lessee.email]) %}
{% endfor %}
{% if app.user.email in emails %}
<tr>
<td>{{ property.propertyCategory }}</td>
<td>{{ property.uniqueName }}</td>
<td>{{ property.address }}</td>
<td>{{ property.city }}</td>
<td>{{ property.zipCode }}</td>
<td>{{ property.rentExcludingCharges }} €</td>
<td>{{ property.charges }} €</td>
<td>{{ property.purchasePrice }} €</td>
<td>
<a href="{{ path('property_show', {'id': property.id}) }}">Voir</a>
{% if is_granted('ROLE_USER') %}
<a href="{{ path('property_edit', {'id': property.id}) }}"><i class="fas fa-edit"></i> édition</a>
{% endif %}
</td>
</tr>
{% endif %}
{% endfor %}
{% else %}
<tr>
<td colspan="16">Vous n'avez pas enregistré de propriétés</td>
</tr>
{% endif %}
开始解决方案:我的请求量减少了
/**
* @param User $user
* @return array
*/
public function findPropertyByUser(User $user): array
{
$qb = $this->createQueryBuilder('p')
->andWhere('p.userProperty = :user')
->setParameter('user', $user)
->orderBy('p.id', 'ASC')
->innerJoin('p.lessees', 'l')
->getQuery();
return $qb->execute();
}
答案 0 :(得分:2)
您需要一个leftJoin之类的
argv
,然后在视图中删除有关电子邮件的所有内容:
/**
* @param User $user
* @return array
*/
public function findPropertyByUser(User $user): array
{
$qb = $this->createQueryBuilder('p')
->leftJoin('p.lessees', 'l')
->andWhere('p.userProperty = :user OR l.email = :userEmail')
->setParameter('user', $user)
->setParameter('userEmail', $user->getEmail())
->orderBy('p.id', 'ASC')
->getQuery();
return $qb->execute();
}
