在两个关系上有条件地查找实体

标签： sql symfony doctrine-orm dql

这是我的问题：

我有3个实体：联系，邮寄和 MailTemplate

邮件仅用于向许多联系人发送 MailTemplate ;在关系方面，邮件由 ManyTomany 与联系人的关系以及 ManyToOne 与<的关系定义强> MailTemplate

我的一些 MailTemplate 实体有一个布尔字段“unique”，以便说这个模板应该多次发送给同一个联系人。说到前端，我有一个视图，我可以选择联系人并向他们发送邮件模板。

以下是这样的事情：我想限制显示的联系人，仅限于那些我没有发送邮件模板的人！

因此，如果 MailTemplate 的字段为“唯一”，我只想获得尚未收到此模板的联系实体;我尝试了很多东西，但是无法用DQL或Query Builder来解决这个问题。因为联系和 MailTemplate 邮件 > ...

我可以获取所有联系人，然后循环浏览邮件并删除其中一些，但我希望这更加优化。

示例数据 

template1 : MailTemplate { id: 1, unique: true }
template2 : MailTemplate { id: 2, unique: false }
template3: MailTemplate { id: 3, unique: true }

user1 : { id: 1 }
user2 : { id: 2 }
user3 : { id: 3}

mailing1 : Mailing { id: 1, contacts: { 1, 2 }, template: 1 }
mailing2: Mailing { id: 2, contacts: { 1 }, template: 3 }

应该导致：

Users available for template1 : user3
Users available for template2 : user1, user2, user3
Users available for template3 : user2, user3

答案 0 :(得分：0)

首先，您必须使关系联系＆lt; - ＆gt;邮寄双向。这意味着必须有一个财产＆＃34;邮件＆＃34;在您的联系人实体中。然后，您可以在表单中使用查询构建器属性，如下所示：

$template = $builder->getData()->getTemplate();
$builder
        ->add('contact', 'entity', 
            array(
                'class' => 'AppBundle:Contact',
                'query_builder' => function($contactRepository) use ($template){

                    return $contactRepository->createQueryBuilder('c')
                        ->leftJoin('c.mailings', 'm', 'WITH', 'm.template = :template')
                        ->where('m.template IS NULL')
                        ->setParameter('template', $template);
                }
            );

这应该只返回没有相关邮件的联系人，模板是当前模板。
