def save(self, *args, **kwargs):
self.slug = slugify(self.user)
super(Profile, self).save(*args, **kwargs)
@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):

instance.profile.save()
>Solution :
You cannot use CreateView to Edit existing object. To Edit profile you should use UpdateView, because CreateView is trying to create NEW Profile object with request.user object, that already has got corresponding Profile object.
