Symfony2 + Doctrine2实体未映射(结果为null)

Symfony2 + Doctrine2 entities not mapped (result is null)

本文关键字：结果 null 映射 Doctrine2 实体 Symfony2 | 更新日期: 2023-09-27

我有两个实体TBag和TCustomer, TBag实体包含对TCustomer的引用，但是当我试图获得我的TBag实体时，相关实体为空。

使用doctrine命令行doctrine:generate:entities从数据库生成实体

谢谢你的时间:-)

TBag data:

id;extn_id;bagNumber;customer_id;store_id;delivery_date;order_remarks;currency;t_bag_status_id
1;;1;3;1;2015-08-25;test;1;0

客户数据:

id;name;firstName;email;phoneNumber;address;postalCode;city;country_id;birthDate;ipAddress;localization   
3;Quentin;Test;quentin.test@outlook.com;0655555555;30 rue 123;86360;Poitiers;0;1994-11-06;192.168.1.24;FR

看起来你创建了一个单向关系你需要创建一个双向关系

从手册:

一对多关联必须是双向的，除非您使用额外的连接表。这是必要的，因为一对多关联中的外键是在"多"端定义的。Doctrine需要一个多对一的关联来定义这个外键的映射。

这个双向映射需要OneToMany关联上的mappedBy属性和ManyToOne关联上的inversedBy属性。

在下面的链接中，你会找到如何做到这一点的例子:
