I've some models from models.Model in django and wish to know if I change it and extend to BaseModel will occur some error when I make migrations. 我在Django中有来自models.Model的模型，希望知道是否进行更改并扩展到BaseModel时会发生一些错误。 Thanks 谢谢

2 个解决方案

否。如果您的BaseModel扩展了models.Model 。

If BaseModel is abstract, then changing a model to inherit from models.Model to BaseModel will not require a migration. 如果BaseModel是抽象的，则更改模型以从models.Model继承为BaseModel将不需要迁移。

If BaseModel is not abstract, then you are switching to multi-table inheritance, and migrations will be required. 如果BaseModel不是抽象的，则您将切换到多表继承，并且将需要迁移。

See the Django docs on inheritance for more info. 有关更多信息，请参见关于继承的Django文档。
