Php Symfony2/条令，通过关系找到了一个新实体

在持久化RoomsConfig之前，请尝试使用
findOneBy
查找BookingRequest，或使用任何方法查找实体，然后在持久化RoomsConfig之前，使用
setBookingRequest
设置找到的实体，尝试使用
findOneBy
查找BookingRequest，或者您用于查找实体的任何内容，然后使用
setBookingRequest
将找到的实体设置为“我不需要对城市和BookingRequest关系产生级联效应”，但您的映射明确说明了这一点。您能告诉我们更多关于您的型号吗？BookingRequest包含一个预订请求：用户信息（姓名、电话、城市）、预订的房间数，我已经在数据库中找到了我需要的所有城市，这就是为什么我不能在城市和BookingRequest之间产生级联效应。RoomsConfig是为每个预订的房间配置的，它的配置就像用户希望在这个房间里有一台电视，在另一个房间里有一台空调“我不需要对城市和BookingRequest关系产生级联效应”，但您的映射明确说明了这一点。您能告诉我们更多关于您的型号吗？BookingRequest包含一个预订请求：用户信息（姓名、电话、城市）、预订的房间数，我已经在数据库中找到了我需要的所有城市，这就是为什么我不能在城市和BookingRequest之间产生级联效应。RoomsConfig是为每个房间预留的，它的配置，就像用户希望在这个房间里有一台电视，在另一个房间里有一台空调有什么办法可以避免这个解决方案？因为如果一个实体有一系列关系。我必须把它们都放好吗？为什么条令认为实体是新的？@Oscar我不知道为什么会发生这种情况，但是如果你不想在数据库中进行findOneBy，这意味着你需要在数据库中进行另一个查询，你可以尝试使用getReference方法，它只准备实体id的对象，如：$this->\u em->getReference（'WhateverBundle:EntityName'，$entity\u id）；有没有办法避免这种解决方案？因为如果一个实体有一系列关系。我必须设置所有这些关系？为什么条令认为实体是新的？@Oscar我不知道为什么会发生这种情况，但如果你不想让它成为findOneBy，这意味着你需要在数据库中进行另一个查询，你可以尝试使用getReference方法，它只对用实体id重新编写对象，如下所示：$this->\u em->getReference（'WhateverBundle:EntityName'，$entity\u id）；
