更改Django模型的related_name属性是否需要向南迁移？ [英] Does changing a django models related_name attribute require a south migration?

问题描述

我有一个带有外键的简单Django模型

I have a simple django model with a ForeignKey

class FooModel(models.Model):
    foo = models.ForeignKey('Foo', related_name="foo_choices")
    bar = models.CharField(max_length=50)

related_name属性已经存在，但是我想更改它。此更改是否需要任何形式的迁移？当我在修改related_name之后运行schemamigration管理命令时，我得到似乎什么都没有改变，但我想验证。

The related_name attribute exists already, but I'd like to change it. Will this change require a migration of any kind? When I run the schemamigration management command after modifying the related_name I get the "Nothing seems to have changed" but I wanted to verify.

推荐答案

否您不需要迁移。

相关名称是用于从相关对象返回到该对象（反向关系）的关系的名称。

Related name is the name to use for the relation from the related object back to this one (the reverse relationship).

related_name 与数据库无关。它由Django的ORM占用以获取查询集结果，因此，如果在模型字段中更改 related_name 属性，则无需迁移。

related_name has nothing to do with the database. It is consumed by the Django's ORM to fetch queryset results, so you dont need a migration if you change the related_name attribute on a models' field.
