django.db.utils.IntegrityError: UNIQUE constraint failed: rango_category__new.slug

Question

I\'m learning Django from Tango with Django but I keep getting this error when I type:

python manage.py makemigrations rango
python manage.py migrate
         


        

Answer 1

python manage.py flush 

Did the trick. Brutal but effective. Warning! All your data in database will be lost. You will have to create superuser and so on...
