我在Django应用程序中有多个用户模型，一个用于OLAROOM，另一个用于REALTOR。正如你所看到的，一切都很成功，但当我尝试验证他们并根据他们的角色重定向他们时，它不起作用。验证工作正常，但不是将Olaroom用户重定向到房间页面，它将我重定向到Realtor_Dashboard，并且用户角色不是房地产经纪人。使用下面的表单，根据保存函数中定义的内容创建用户。但是，当我尝试验证他们并根据他们的角色将用户重定向到页面时，它不起作用，我使用相同的方法，类似于以下内容：user.Role.REALTOR和user.Role.OLAROOM。请问我如何解决这个问题？

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})
