Я пишу базовый c код представления регистрации с помощью Django framework.
У меня есть следующий код:
def register(request):
if request.method == 'POST':
username = request.POST.get("username")
password = request.POST.get("password")
email = request.POST.get("email")
firstname = request.POST.get("firstname")
lastname = request.POST.get("lastname")
userObj = User.objects.filter(username)
if userObj.exists():
return HttpResponse("username already exists")
emailObj = User.objects.filter(email)
if emailObj.exists():
return HttpResponse("email already exists")
newUser = User.objects.create_user(username, email, password, first_name=firstname, last_name=lastname)
if newUser is not Null:
newUser.save()
# render main menu page
return HttpResponse("user successfully registered")
else:
return HttpResponse("error creating newUser")
Ошибка из-за линий userObj = User.objects.filter(username) и emailObj = User.objects.filter(email)
Вот часть трассировки:

Что можно сделать, чтобы избежать этого, потому что я делаю только базовую c Django регистрацию в соответствии с требованиями самой документации ..?
