即使映射了entity1和entity2，将表单数据提交到entity1和entity2_id列也是null

标签： symfony symfony-forms

我有两个实体（Plan和PricingTier），它们被设置为相互映射。 PricingTier设置为oneToMany，Plan设置为manyToOne。映射列位于Plan实体中; plans数据库表有一个pricing_tier_id列，它将两个表/实体链接在一起。

我有一个创建新计划的表单。表单在Twig文件中正确生成，并在发布$ request-＆gt; request-＆gt; getAll（）;返回已发布值的数组。在数组中，我可以看到pricingTierId已明确设置为我选择的定价层的id。当我执行以下操作时：

$form->bind($request);
$newPlan = $form->getData();
$em = $this->getDoctrine()->getEntityManager();
$em->perist($newPlan);
$em->flush();

我得到一个抛出异常，说pricing_tier_id不能为NULL。我对$ newPlan变量做了一个var_dump（），它看起来返回一个对象，包括映射定价层的对象。

有人可以建议解决我为什么会收到此错误的解决方案吗？相关代码和错误如下。

那应该是与此相关的所有文件。我没有包含Twig文件，因为它只是一行呈现由PlanController中的createView（）魔术方法生成的表单。

先谢谢！

在Plan.orm.yml中：

pricingTierId:
      column: pricing_tier_id
      type: integer

与多对一联接的列名相同。这可能是一种不好的做法。这不是nullable：true，可能是你问题的根源。显然，您不需要此字段。同样在你的表单中，你正在为pricingTierId加载实体类，而priceTierId不是一个实体，我认为symfony对此非常困惑。

    $builder->add('pricingTierId', 'entity', array(             // add pricingTier
    'class' => 'etrakOnlineOrderProcessingBundle:pricingTier',  // not pricingTierId
    'property' => 'name',
    'label' => "Select Pricing Tier: "
    ));

我希望如果您删除有问题的yaml部分并调整表单类型，您的问题就会消失。
