如何修复 Django 中“无效的密码格式或未知的哈希算法”错误？

Question

Have a good day!

I created a custom user model in Django. When I try to create a admin user pofile - all is ok. But when I try to create a simple user profile, I see "invalid password format or unknown hashing algorithm" error in the admin interface. How to fix it?

class UserProfileManager(BaseUserManager):

    def create_user(self, email, date_of_birth, password):
        """
        Creates and saves a User with the given email, date of
        birth and password.
        """
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
            date_of_birth=date_of_birth,
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

Answer 1

When I tried to create new user, I used get_or_created method. But I forgot to override it. Now it works!))

Answer 2

try this

from django.contrib.auth.hashers import make_password
...
def create_user(self, email, date_of_birth, password):
    """
    Creates and saves a User with the given email, date of
    birth and password.
    """
    if not email:
        raise ValueError('Users must have an email address')

    user = self.model(
        email=self.normalize_email(email),
        date_of_birth=date_of_birth,
    )

    user.set_password(make_password(password))
    user.save(using=self._db)
    return user

def create_superuser(self, email, date_of_birth, password):
    """
    Creates and saves a superuser with the given email, date of
    birth and password.
    """
    user = self.create_user(email,
        password=make_password(password),
        date_of_birth=date_of_birth
    )
    user.is_admin = True
    user.save(using=self._db)
    return user

   ...
