How do you drop all tables from an app in Django 1.8+?
I am upgrading Django 1.4 to 1.8, and there are some 3rd party applications whose schema changed dramatically to support the upgrade. I want to reset these applications so I can recreate the corresponding tables from them. In the previous Django iterations, I can do either
./manage.py sqlclear appname
./manage.py reset appname
But both sqlclear and reset are already deprecated in Django 1.8. Is there a clean way to do this aside from manually erasing the tables from the database?
As of Django 1.8+ migrate appname zero unapplies all the migrations and deletes the tables docs
