Проблема с регистрацией пользователя Django: «Произошла ошибка. Повторите попытку». ⇐ Html

[Anonymous]

Я пытаюсь реализовать регистрацию пользователей и войти в свой проект Django с помощью AJAX. Однако, даже когда я правильно вводился по всей информации, я продолжаю получать сообщение об ошибке:
«Произошла ошибка. Пожалуйста, попробуйте еще раз». Ответ Ajax в консоли браузера, но он всегда возвращает сообщение об ошибке без указания того, что пошло не так.def login_and_register(request):
login_form = LoginForm()
register_form = CustomUserRegistrationForm()
schools = School.objects.all()
graduation_years = GraduationYear.objects.all()

if request.method == 'POST':
if 'register_submit' in request.POST:
register_form = CustomUserRegistrationForm(request.POST)
if register_form.is_valid():
try:
user = register_form.save()
login(request, user)

if request.headers.get('x-requested-with') == 'XMLHttpRequest':
return JsonResponse({
'success': True,
'redirect_url': reverse('school_login'),
'message': "Registration successful! Please add your school information."
})

messages.success(request, "Registration successful! Please add your school information.")
return redirect('school_login')

except Exception as e:
print(f"Registration error: {str(e)}")
if request.headers.get('x-requested-with') == 'XMLHttpRequest':
return JsonResponse({
'success': False,
'errors': [f"An error occurred during registration: {str(e)}"]
}, status=400)
messages.error(request, f"An error occurred during registration: {str(e)}")

print("Form invalid:", register_form.errors)

Что может быть проблемой?
Я не вижу никаких ошибок проверки в register_form.errors. < /p>
Метод .save () работает внутри блока Try-Except, но он не поднимает никаких конкретных исключений. Эта проблема и как я могу отлаживать его дальше? Заранее спасибо!
