create django user who can not login

Question

I want to create a user whom I'm using as a ForeignKey and i don't want those users can login to system. I have no idea how to go on. (about setting set_unusable_password() or None, and how to perform it):

my accounts.py file is as

class User(AbstractBaseUser):
    GENDER = (("MALE", "Male"), ("FEMALE", "Female"))
    
    user_type = models.CharField(max_length=50, choices=Types.choices, default=Types.PATIENT)
    full_name = models.CharField(max_length=255, blank=True, null=True)
    phone = models.CharField(max_length=255, unique=True)
    email = models.CharField(max_length=255, blank=True, null=True, unique=True)
    active = models.BooleanField(default=False)
    gender = models.CharField(max_length=15, choices=GENDER)
    admin = models.BooleanField(default=False)
    staff = models.BooleanField(default=False)
    timestamp = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    USERNAME_FIELD = "phone"  # username
    REQUIRED_FIELDS = []
    objects = UserManager()

thanks in advance guys. <3

Answer 1

you can use the is_active field of the user record

is_active Boolean . Designates whether this user account should be considered active. We recommend that you set this flag to False instead of deleting accounts; that way, if your applications have any foreign keys to users, the foreign keys won't break.

Answer 2

In View you should also check whether the user is active or not. For Eg:

def user_login(request):
    if request.method == "POST":
        username = request.POST.get("username")
        password = request.POST.get("password")
        user = authenticate(username = username,password = password)
        if user is not None and user.active:
            login(request,user)

As you have overide your user model and changed active field from is_active.If active field is False then it will not allow the user to log in if the user is active it will allow user to log in.
