可以将Django中的模型类型连接到一个对象中吗？

问题描述

例如，我有两个模型对象Person和Address。地址有个人id的引用。一个查询看起来像是将它们作为一个对象一起拖出来，还是不可能用Django？

解决方案

阅读，然后可以使用 person.address 获取地址。

For example I have two model objects, Person and Address. Address has a reference to a Person id. What would a query look like that pulls them out together as one object, or is that not possible to do with Django?

解决方案

Have a read of the Django docs on related objects. Going from a Person to related Addresses is equivalent to going from a Blog to its related Entries in the examples.

If you have a person, you can do person.address_set.all() to get all addresses for that person.

If each person has only one address, use a OneToOneField, and then you can use person.address to get the address.
