We make changes to our app’s admin.py file to register a model with Django’s admin interface. In the app folder where our models reside, we must access the admin.py file. For example, if we have a polls app and want to register a model named “Question,” we should open “polls/admin.py” and import the Question model, then write: admin.site.register (Question). Our Question model will be registered with the admin site as a result of this.
