Django Admin comes with some Models registerd by default. There a some occasions where you might want to remove a Model from the admin pages.
This is done in the admin submodule. If your app wass created using manage.py startapp, the admin.py file should already lay in your app module. Otherwise create it.
#myapp/admin.py
from django.contrib import admin
from django.contrib.auth.models import User
admin.site.unregister(User)
