This is an extremely simple way to disable Django's behavior of updating a user last_login field on login. You could use this to connect a Django app to a read-only database, such as a replica, and still having a more or less functional application.

- Add "nolastlogin" to your INSTALLED_APPS setting like this:
INSTALLED_APPS = [

'nolastlogin',

- Add this to the settings:
NO_UPDATE_LAST_LOGIN = True
