在Django Admin中，选项可以依赖于其他一些值吗？

I have 3 models in Django: Country, City, and Store.
When I create a new store in Django admin, I want to choose Country and City.
After I decide the Country, how can I make the options in City relate to the Country?

我在Django中有3个模型:Country,City和Store。当我在Django admin中创建一个新商店时,我想选择Country和City。在我决定国家之后,我如何让城市中的选项与国家相关?

Thank you so much!
