The self.slug has default = ""
so in the save method it doesn’t enter the condition, so the super doesn’t work, I recommend modifying the save method for that:
def save(self, *args, **kwargs):
if self.slug is None or self.slug == "":
year = datetime.today().year
self.slug = slugify(str(year) + '-' + str(self.category) + '-' + str(self.title))
super(Blog, self).save(*args, **kwargs)
