I am trying to make connection with MS SQL with following settings
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'dbName',
'USER': 'userName',
'PASSWORD': 'password',
'HOST':'hostName',
'PORT': 1433,
'OPTIONS': {
'driver': "SQL Server"
}
}
}
I had to downgrade to : pip install 'django-pyodbc-azure<1.11' which was
otherwise giving me a error of No Server/DSN found. However after
downgrading when I execute "python manage.py makemigrations" or python
manage.py runserver.
Following is my error, which I am unable to understand. Any help would be
of great help.
Thanks in advance.

Comment:
First of all `django-pyodbc-azure < 1.11` is not compatible with Django
3.0, secondly it's a 3rd-party package so it's not an issue in Django
itself, and finally, please don't use trac as a support channel.

Comment (by Andrew Badr):
Commenting in case this helps anyone else. I hit this same error trying to
upgrade a simple Django 1.9.13 project from python 2.7 to python 3.8.
`RuntimeError: __class__ not set defining 'AbstractBaseUser' as <class
'django.contrib.auth.base_user.AbstractBaseUser'>. Was __classcell__
propagated to type.__new__?`
Not using `django-pyodbc-azure` or anything else unusual. This error seems
be coming from within Django itself.(File
"/app/.heroku/python/lib/python3.8/site-
packages/django/contrib/auth/base_user.py", line 49). What's strange is
that the error doesn't happen for my locally, only on Heroku.
Upgrading to Django 1.11 fixed the issue.
