Hi everyone, we are trying in our application to support multiple Django versions, specifically 1.7 to 1.9. But we encountered a problem with `User.last_login` field. We use custom User model based on `AbstractBaseUser` as specified by the documentation. Everything was fine in Django 1.7, but we got stuck when we wanted to add support for Django 1.8, where the `last_login` was modified to allow NULL values. As recommended by https://docs.djangoproject.com/en/1.10/topics/migrations/#supporting-multiple-django-versions we have migrations generated in Django 1.7 (lowest supported version) an thus `last_login` is NOT NULL, but that causes tests to fail when run in Django 1.8/1.9, since code allows `last_login` to be NULL.
We can't even redefine the field in our model, which would be the most straight forward solution, but that's not allowed by Django either. What's the correct solution for this problem? It looks to us like there are some unresolved issues regarding the model and migrations design.
