transaction 'atomic' block error

[uhurusurfa]

My project has been using DDF for almost a year now and has worked great. Just tried ugrading to 3.* version and this error shown below is thrown. It seems to happen with most invocations of the G() constructor running Django 2.2.8 and Python 3.7.5 (works fine with DDF 2.0.0). Has anyone got any ideas?

I will take a look into this, fix and create a new release! Thanks for reporting!

There is an error in the test/ddf, maybe an IntegrityError. The first step is having a better error message to understand what is going on, so you can try to use the new TransactionTestCase class.

from django.test import TransactionTestCase as TestCase

Please, re-open the issue after you get more details.

Also, please try the version 3.0.3.
