У меня есть ссылка на локальную переменную перед ошибкой назначения, и я перепробовал множество способов, которые я могу использовать, чтобы исправить это. Любая помощь будет очень признательна

Это мое Views.py (ошибка после верхней части второго оператора if)

 def call_back_url(request):  reference = request.GET.get('reference')  # We need to fetch the reference from PAYMENT  check_pay = PayHistory.objects.filter(paystack_charge_id=reference).exists()  if check_pay == False:  # This means payment was not made error should be thrown here...  print("Error")  else:  payment = PayHistory.objects.get(paystack_charge_id=reference)  # We need to fetch this to verify if the payment was successful.  def verify_payment(request):  url = 'https://api.paystack.co/transaction/verify/' reference  headers = {  'Authorization': 'Bearer ' settings.PAYSTACK_SECRET_KEY,  'Content-Type' : 'application/json',  'Accept': 'application/json',  }  datum = {  "reference": payment.paystack_charge_id  }  x = requests.get(url, data=json.dumps(datum), headers=headers)  if x.status_code != 200:  return str(x.status_code)    results = x.json()  return results  initialized = verify_payment(request)  if initialized['data']['status'] == 'success':  PayHistory.objects.filter(paystack_charge_id=initialized['data']['reference']).update(paid=True)  new_payment = PayHistory.objects.get(paystack_charge_id=initialized['data']['reference'])  instance = Membership.objects.get(id=new_payment.payment_for.id)  sub = UserMembership.objects.filter(reference_code=initialized['data']['reference']).update(membership=instance)  user_membership = UserMembership.objects.get(reference_code=initialized['data']['reference'])  Subscription.objects.create(user_membership=user_membership, expires_in=dt.now().date()   timedelta(days=user_membership.membership.duration))  return redirect('subscribed')  return render(request, 'payment.html')   def subscribed(request):  return render(request, 'subscribed.html')  

Обратная связь, которую я получаю:

пробовать:
