[Answer]-Why is the option "admin | log entry | Can change log entry" showing?

The history is a model that comes with django admin. It uses a generic foreign key so it can log actions for any object.

To view the history of an object click on the edit form, and then click on the history button on the top right. For example, in this screen (from chapter 6 of the djangobook website), you can see the history button on a user’s edit form.
