Description (last modified by )
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.

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 me locally, only on Heroku.
Upgrading to Django 1.11 fixed the issue.
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.
