在多个嵌入式集合表单中查询

问题描述

除了我的之前的问题.我现在想限制表单的输入字段.这样就只有供应商的输入字段，例如 id: 2 .而不是与订单相关的整个供应商集合.问题是，我在嵌入式集合中有一个嵌入式集合.我给我的第一个表单类型 $order .

In addition to my previous question. I now want to limit the input fields of my form. So that there are only input fields for the Supplier for example with the id: 2 . And not the whole collection of suppliers related to the Order. The problem is, that I have an embedded collection in an embedded collection. And i give $order to my first formtype.

$order = $this->getDoctrine()
        ->getRepository('AcmeAppBundle:PurchaseOrder')
    $form = $this->createForm(new ProducedAmountOrderType(), $order);

我的问题是，我不能在集合的表单类型中使用查询构建器.那么，如何只显示一个供应商的输入字段，而不显示与实体相关的每个人的输入字段?

My problem is, that I can't use query builder in a form type for collections. So, how can I display only the input fields for one supplier and not for everyone related to the Entity?

推荐答案

我用这个 $order 查询解决了这个问题:

I solved it with this $order query:

$order = $this->getDoctrine()->getManager()->createQuery("
        SELECT o, a , s
        FROM AcmeAppBundle:PurchaseOrder o
        JOIN o.purchaseOrders a
        JOIN a.articleOrderReferences s
        WHERE o.id = :orderId
          AND s.supplier = :supplierId
          AND s.amount > 0
       ")
                   ->setParameter('orderId', $orderId)
                   ->setParameter('supplierId', $supplierId)
                   ->getOneOrNullResult();
