So I made the ultimate error. I put a BooleanField in my models.py, when I
made migrations I set default col value to the empty string ''.. Then I
migrated and got a validation error. However, I have tried to delete the
model containing BooleanField, delete my database file, and I even ran
manage.py flush and cannot seem to get rid of this error. If anyone has
any experience with BooleanField errors please help. My traceback from my
terminal is below:
