with transaction.atomic() not working for Azure SQL Database - django

Question

I use django-pyodbc-azure 2.1.0.0 for the connection with an Azure SQL database which works fine.
When I understand the documentation of django-pyodbc-azure correctly, transactions should be supported.
However, this code immediately updates the row. I would expect, that the row is updated after 20 seconds.
from django.db import transaction
from myapp.models import MyModel
import time
with transaction.atomic():
MyModel.objects.filter(id=1).update(my_field='Test')
time.sleep(20)
Am I doing something wrong? Do I need to specifiy certain settings on the Azure SQL database?
When I set AUTOCOMMIT = False in my database settings, then the following code will not update the row at all.
MyModel.objects.filter(id=1).update(my_field='Test')
time.sleep(20)
transaction.commit()
My current settings.py
'azure_reporting': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'reporting_db',
'HOST': 'xxxxxx.database.windows.net',
'PORT': '',
'USER': 'xxxx#xxxxxx.database.windows.net',
'PASSWORD': 'xxxxxx',
'OPTIONS': {
'driver': 'ODBC Driver 17 for SQL Server'
}
}

Please make sure you have set the AUTOCOMMIT=true on database settings:
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'HOST': 'yourserver.com',
'PORT': '1433',
'NAME': 'your_db',
'USER': 'your_user',
'PASSWORD': 'your_pw',
'AUTOCOMMIT': True,
'OPTIONS': {
'driver': 'ODBC Driver 13 for SQL Server',
},
},
}
No error happened, the only things what we can do is recheck the configuration of django-pyodbc-azure.
As you said: When I set AUTOCOMMIT = False in my database settings, then the following code will not update the row at all.
I think the transactions should works well.
Hope this helps.
