Question

当我清除付款过程数据时，我的ipn数据库中没有数据。.它引发错误...字段'option_selection1'没有默认值。.

def home1(request):
    args = {}
    paypal_dict = {
        "business": "***&****",
        "amount": "1.00",
        "currency_code": "INR",
        "item_name": "police",

        "notify_url": request.build_absolute_uri(reverse('paypal-ipn')),
        #"notify_url": "http://13.233.99.180:8000/a-very-hard-to-guess-url/",
        "return": request.build_absolute_uri(reverse('api.views.paypal_return')),
