我有两个实体TBag和TCustomer，TBag实体包含对TCustomer的引用，但是当我尝试获取我的TBag实体时，关联实体为空。
使用doctrine命令行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
感谢您的时间： - ）
TBag数据：
id;name;firstName;email;phoneNumber;address;postalCode;city;country_id;birthDate;ipAddress;localization

看起来你创建了一个你需要创建双向的方向关系
来自手册：
除非您使用其他连接表，否则一对多关联必须是双向的。这是必要的，因为在“许多”方面定义了一对多关联中的外键。 Doctrine需要一个多对一的关联来定义这个外键的映射。
此双向映射需要OneToMany关联上的mappedBy属性和ManyToOne关联上的inversedBy属性。
在下面的链接中，您将找到如何操作的示例：
