failed to authenticate multiple user in django

I have multiple user models in my Django app, one for OLAROOM and the other one for REALTOR. As you can see, everything is working successfully, but when I try to authenticate them and redirect them based on their role, it does not work. The authentication is working fine, but instead of redirecting the Olaroom user to the Rooms page, it is redirecting me to the Realtor_Dashboard, and the user role isn't a Realtor. Using the form below, the user is created based on what is defined in the save function. However, when I try to authenticate them and redirect the user to the page based on their role, it doesn't work, and I'm using the same method, something like this: user.Role.REALTOR and user.Role.OLAROOM. How can I solve this problem please?

def login(request):
    if request.method == 'POST':
        form = AuthenticationForm(data=request.POST)
        if form.is_valid():
            username = request.POST.get('username')
            password = request.POST.get('password')
            user = authenticate(username=username, password=password)
            if user is not None:
                if user.Role.REALTOR:
                    auth_login(request, user)
                    return redirect('Realtor_Dashboard')
                elif user.Role.OLAROOM:
                    auth_login(request, user)
                    return redirect('Rooms')
                else:
                    messages.error(request, 'Invalid Creadentials')
    else:
        form = AuthenticationForm()        
    return render(request, 'Login/login.html', {'form':form})

User Models

class User(AbstractUser):
    class Role(models.TextChoices):
        ADMIN = "ADMIN", 'Admin'
        REALTOR = "REALTOR", 'Realtor'
        OLAROOM = "OLAROOM", 'Olaroom'
    
    base_role = Role.ADMIN

    role = models.CharField(max_length=225, choices=Role.choices)
    username = models.CharField(max_length=15, unique=True)
    first_name = models.CharField(max_length=225)
    last_name = models.CharField(max_length=225)
    email = models.EmailField(unique=True)
    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']
    def save(self, *args, **kwargs):
        if not self.pk:
            self.role = self.base_role
            return super().save(*args, **kwargs)

    def __str__(self):
        return str(self.username)


class OlaroomsManger(BaseUserManager):
    def get_queryset(self, *args, **kwargs):
        results = super().get_queryset(*args, **kwargs)
        return results.filter(role=User.Role.OLAROOM)

class Olaroom(User):
    base_role = User.Role.OLAROOM

    company_name = models.CharField(max_length=225)
    address = models.CharField(max_length=225)
    phone_number = models.CharField(max_length=15)
    country = CountryField()

    olaroom = OlaroomsManger()

    def welcome(self):
        return "Only for Olaroom"

class RealtorManger(BaseUserManager):
    def get_queryset(self, *args, **kwargs):
        results = super().get_queryset(*args, **kwargs)
        return results.filter(role=User.Role.REALTOR)

class Realtor(User):

    base_role = User.Role.REALTOR
    address = models.CharField(max_length=225)
    phone_number = models.CharField(max_length=15)
    country = CountryField()
    state = models.CharField(max_length=225)

    realtor = RealtorManger()

    def welcome(self):
        return "Only for Realtor"

forms:

class OlaroomSignUpForm(UserCreationForm):
    class Meta(UserCreationForm.Meta):
        model = Olaroom
        fields = ['username', 'email', 'company_name', 'address', 'phone_number', 'country']

        def save(self, commit=True):
            user = super().save(commit=False)
            user.Role.OLAROOM
            if commit:
                user.save()
            return user

class RealtorSignUpForm(UserCreationForm):
    class Meta(UserCreationForm.Meta):
        model = Realtor
        fields = ['username', 'email', 'first_name', 'last_name', 'address', 'phone_number', 'country', 'state']

        def save(self, commit=True):
            user = super().save(commit=False)
            user.Role.REALTOR
            if commit:
                user.save()
            return user

the issue i'm facing is related to how i'm checking the user's role and trying to redirect them after authentication. In my code, i'm checking user.Role.REALTOR and user.Role.OLAROOM, but this is not the correct way to check the user's role based on my models.

Instead, I should check the role attribute of the user instance to determine their role and redirect accordingly.

def login(request):
    if request.method == 'POST':
        form = AuthenticationForm(data=request.POST)
        if form.is_valid():
            username = request.POST.get('username')
            password = request.POST.get('password')
            user = authenticate(username=username, password=password)
            if user is not None:
                if user.role == User.Role.REALTOR:
                    auth_login(request, user)
                    return redirect('Realtor_Dashboard')
                elif user.role == User.Role.OLAROOM:
                    auth_login(request, user)
                    return redirect('Rooms')
                else:
                    messages.error(request, 'Invalid Credentials')
    else:
        form = AuthenticationForm()        
    return render(request, 'Login/login.html', {'form': form})

In this updated code, Instead of using user.Role.REALTOR or user.Role.OLAROOM, I'm using user.role == User.Role.REALTOR and user.role == User.Role.OLAROOM which means: If the user's role is REALTOR, it logs in the user using auth_login and redirects to a Realtor_Dashboard page. If the user role is OLAROOM, it logs in the user and redirects to a Rooms page.
