Why Aren't Passwords Hashed for Custom Users Created via the Admin Site?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm having an issue with my custom user model where only the superuser's password is hashed, and regular user passwords are stored as plaintext. I suspect it's because the passwords aren’t being hashed when creating new users through the admin site. I've also tried designating some users as superusers, but they still can't log in, which leads me to believe the problem is with the password hashing process.

Below are the relevant code snippets:

PYTHON
class CustomUser(viewsets.ModelViewSet):
    serializer_class = UserSerializer
    queryset = CustomUserModel.objects.all()

PYTHON
class CustomUser(AbstractUser):
    ACCOUNT_TYPE = [(‘1’, ‘Student’), (‘2’, ‘Teacher’)]
    accountType = models.CharField(max_length=1, choices=ACCOUNT_TYPE, default=‘1’)
    classCode = models.CharField(max_length=30, blank=True)
    objects = CustomUserManager()  # new
    def __str__(self):
        return self.email

PYTHON
class CustomUserManager(BaseUserManager):
    def create_user(self, email, accountType, classCode, password):
        if not email:
            raise ValueError(‘Users must have an email address’)
        user = self.model(
            email=self.normalize_email(email),
            accountType=accountType,
            classCode=classCode,
        )
        user.save(using=self._db)
        return user

I've attempted to implement a CustomUserManager in models.py, but there’s no evidence that it’s hashing the passwords. How can I ensure that passwords are properly hashed when creating new custom user accounts?

Password Hashing Issue in Custom User Model

I can see the issue in your CustomUserManager implementation. The problem is that you're not setting the password using Django's password hashing mechanism before saving the user.

The Problem

In your create_user method, you're creating the user object and saving it, but you're not actually setting the password with Django's built-in password hashing. This is why regular users have plaintext passwords while superusers (likely created through createsuperuser command) have properly hashed passwords.

Solution

You need to modify your CustomUserManager to use the set_password() method, which properly hashes passwords using Django's password hashing system:

PYTHON
class CustomUserManager(BaseUserManager):
    def create_user(self, email, accountType, classCode, password=None):
        if not email:
            raise ValueError('Users must have an email address')
        user = self.model(
            email=self.normalize_email(email),
            accountType=accountType,
            classCode=classCode,
        )
        if password:
            user.set_password(password)  # This properly hashes the password
        user.save(using=self._db)
        return user
        
    # You should also implement create_superuser method
    def create_superuser(self, email, accountType, classCode, password=None):
        user = self.create_user(
            email=email,
            accountType=accountType,
            classCode=classCode,
            password=password,
        )
        user.is_staff = True
        user.is_superuser = True
        user.save(using=self._db)
        return user

By using the set_password() method, Django will automatically hash the password using the algorithm specified in your PASSWORD_HASHERS setting (by default, this is PBKDF2 with SHA256).

Make sure you also implement the create_superuser method as shown above to ensure consistent behavior when creating superusers.

After making these changes, new users created through your custom manager will have properly hashed passwords, allowing them to log in successfully.
