Put location field in django admin

Hi everyone, I hope you are fine.
I want to put a location field in a django model in admin that the admin can set a location and then the latitude and longtitude will be saved without using google map api.
I will thank if anyone give me a piece of guidance.

What do you mean by “set a location”? If you’re talking about selecting a name, then you need some kind of data source showing the relationships of those names to their respective lat & lon values.
