[英]Doctrine2: dynamic entity associations, many targetEntity mapped by one field
I have a Entity called Event which has 我有一个名为Event的实体
I would now like to access this target entity inside my Event-Entity somehow but im now sure how to do it. 我现在想以某种方式访问我的Event-Entity中的这个目标实体,但我现在确定如何做到这一点。 I'd like to access the different target Entities in a twig template using something like
我想使用类似的东西访问树枝模板中的不同目标实体
{% if event.getClassName() == "User" %}
{{ if event.getUser().getName() }}
{% endif %}
Edit: Just to be clear, the only thing im interested so far is how to create the relation properly. 编辑:为了清楚,到目前为止我唯一感兴趣的是如何正确地创建关系。 Outside a ORM World you would probably use a join statement for this.
在ORM世界之外,您可能会使用连接语句。 It is like i have many target Entities mapped by one field.
就好像我有一个由一个字段映射的目标实体。
So far im using the entity repository and DI to load the associated Entities, but i find that ugly knowing there is a JOIN Statement which i could use: 到目前为止我使用实体存储库和DI加载相关的实体,但我发现丑陋知道有一个JOIN语句,我可以使用:
public function getUpcomingEvents(){
$query = $this->createQueryBuilder('E')
->where('E.resolved = false')
->orderBy('E.notify_date', 'ASC')
->setMaxResults( $limit );
$res = $query->getQuery()->getResult();
$res = $this->attachAssociatedObjects($res);
return $res;
}
public function attachAssociatedObjects($res){
foreach ($res as $key => $entity) {
$assocObject = $this->getEntityManager()->getReference('My\Bundle\Entity\\'.$entity->getClassName(), $entity->getTargetId());
$res[$key]->setAssociatedObject($assocObject);
}
return $res;
}
Twig 属性功能是您所需要的。
