Overview
This is a personal note from researching how to keep edit history in Django.
As shown in the following message, by default, edit history is recorded for changes made through the admin interface, but not for changes made through other interfaces.
This object doesn’t have a change history. It probably wasn’t added via this admin site.

So I tried using the following package.
https://django-simple-history.readthedocs.io/en/latest/
I was able to use it without issues by following the quick start page below.
https://django-simple-history.readthedocs.io/en/latest/quick_start.html
References
As shown below, tables related to edit history were added, and edit history is now being recorded.

Additionally, edit history like the following can now be viewed from the admin interface. I was able to confirm change history from screens other than the admin interface.

Summary
I hope this serves as a useful reference for keeping edit history in Django.
