Tengo la variable local referenciada antes del error de asignación y he probado muchas formas que puedo usar para arreglar esto. Cualquier ayuda sería muy apreciada

Este es mi Views.py (el error después de la parte superior de la segunda declaración 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')
