I am using django 1.7 and I just added a custom user model. When I run either python3 manage.py makemigrations or python3 manage.py migrate I get t
python3 manage.py makemigrations
python3 manage.py migrate
Django 1.7.1 added support for the preserve_default param in AlterField. Therefore an upgrade of Django from version 1.7 will resolve the issue.
pip install django --upgrade python manage.py migrate
