我有两个设置为相互映射的实体（Plan 和 PricingTier）。PricingTier 设置为 oneToMany，Plan 设置为 manyToOne。映射列在计划实体中；计划数据库表有一个pricing_tier_id 列，将两个表/实体链接在一起。
我有一个创建新计划的表格。表单在 Twig 文件中正确生成，并在发布时 $request->request->getAll(); 返回已发布值的数组。在数组中，我可以看到 priceTierId 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();
我得到一个抛出的异常，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。
谁能建议我为什么会收到此错误的解决方案？相关代码和错误如下。

这应该是与此相关的所有文件。我没有包含 Twig 文件，因为它只是呈现由 PlanController 中的 createView() 魔术方法生成的表单的一行。
先谢谢了！
