How to check user type after login ? DJANGO

Question

I have two user types in my application. How do I check user type after login? My login view extends django's LoginView. In my Login View, i tried with form_valid, but I think it does validation before authentication.

models.py

class CustomUser(AbstractUser):
    is_client = models.BooleanField(default=False)
    is_supermarket = models.BooleanField(default=False)

    def __str__(self):
        return self.username

views.py

class LoginView(LoginView):
    
    
    def get(self, request, *args, **kwargs):
    #check if the user is logged in and redirect to home page
        if request.user.is_authenticated:
            return redirect('produtos:home')
        return super(LoginView, self).get(request, *args, **kwargs)

Answer 1

Is this what you need?

class LoginView(LoginView):
    
    
    def get(self, request, *args, **kwargs):
    #check if the user is logged in and redirect to home page
        if request.user.is_authenticated:
            return redirect('produtos:home')
        if request.user.is_supermarket:
            return redirect('supermarket-login') #your unique login page for supermarket user
        return super(LoginView, self).get(request, *args, **kwargs)

Answer 2

I don't know if it's the best approach, but I get the expected behavior

class LoginView(LoginView):
        
    def get(self, request, *args, **kwargs):
        if request.user.is_authenticated:
            return redirect('produtos:home')
        return super(LoginView, self).get(request, *args, **kwargs)
    
    def form_valid(self, form):
        if form.get_user().is_supermarket:
            self.request.session.flush()
            logout(self.request)
            return redirect('login')
        return super().form_valid(form)
