You are trying to add a non-nullable field 'new_field' to userprofile without a default

Question

I know that from Django 1.7 I don\'t need to use South or any other migration system, so I am just using simple command python manage.py makemigrations

Answer 1

Do you already have database entries in the table UserProfile? If so, when you add new columns the DB doesn't know what to set it to because it can't be NULL. Therefore it asks you what you want to set those fields in the column new_fields to. I had to delete all the rows from this table to solve the problem.

(I know this was answered some time ago, but I just ran into this problem and this was my solution. Hopefully it will help anyone new that sees this)
