null value in column "last_login" violates not-null constraint

Question

Having issues getting rid of this error.

I'm trying to use Digital Ocean to deploy my Django app. I configured Postgres, but when I'm trying to register a new user in my app, I get this problem.

I've tried running python manage.py makemigrations and python manage.py migrate and they work fine. The SQL migrations are completed upon migration.

Answer 1

Try add this to your imports:

from django.utils import timezone

Then wherever you grab the user's data to save the new user add before the save procedure:

<user_object>.last_login = timezone.now() 

Answer 2

I was upgrading from django 1.7 to django 1.10 when I ran into this. What it ended up being was I needed to run python manage.py migrate to update the database tables and columns.
