Why doesn't the Django database record existence check work?

Question

Django

I need to check who the user is when entering the personal account. The code below is not working, please tell me why? All entries are in the database. Moreover, if instead of username_temp I enter a specific phone number in the code, then it will work and display my role in context.

def lk_point(request):
    context = {}
    username_temp = request.user.get_username
    context['username'] = username_temp
    if point.objects.filter(telephone=username_temp).exists():
        context['info'] = "Вы - пункт"
    elif client.objects.filter(telephone=username_temp).exists():
        context['info'] = "Вы - клиент"
    return render(request, 'lk_point.html', context)

Answer 1

probably because request.user.get_usernamethis is a method, not a field with a value, and it must be called
add brackets to call the method that will return the username
username_temp = request.user.get_username()
