class BmUserManager(BaseUserManager):

    def create_user(self, useremail, display_name, password=None):
        if not useremail:
            raise ValueError('Users must have an email address')

        user = self.model(useremail=BmUserManager.normalize_email(useremail))
        user.display_name = display_name
        user.email = useremail
        user.set_password(password)
        user.save(using=self._db)
        return user

self.model(useremail=BmUserManager.normalize_email(userremail)) 有什么用？
