我正在建立一个在线商店。
我的订单数据存储在请求中。我的观点有以下一般结构:
payment.py
def payment(request):
order = request.order # Getting the order instance
# do some stuff
return render_to_response("payment.html")
我使用django-paypal
。我关注this tutorial。 PayPal调用以下函数,它告诉我付款已成功。
payment_paypal_ipn_signal_handler.py
# Almost entirely copied from the django-paypal tutorial
from paypal.standard.models import ST_PP_COMPLETED
from paypal.standard.ipn.signals import valid_ipn_received
def payment_paypal_ipn_signal_handler(sender, **kwargs):
ipn_obj = sender
if ipn_obj.payment_status == ST_PP_COMPLETED:
# WARNING !
# Check that the receiver email is the same we previously
# set on the business field request. (The user could tamper
# with those fields on payment form before send it to PayPal)
if ipn_obj.receiver_email != "receiver_email@example.com":
# Not a valid payment
return
# ALSO: for the same reason, you need to check the amount
# received etc. are all what you expect.
# Undertake some action depending upon `ipn_obj`.
if ipn_obj.custom == "Upgrade all users!":
Users.objects.update(paid=True)
# Here I should add the code that handles a successful payment
request.order.paid = True # How do I get my 'request' here?
else:
#...
valid_ipn_received.connect(show_me_the_money)
但是,我仍然需要我的order
实例才能将其设置为付费。如何在PayPal调用的函数中获取我的数据?

我找到了解决方案。您可以通过custom
参数中的PayPalPaymentsForm
属性传递信息。
<强> payment_paypal.py 强>
def payment_paypal(request):
paypal_dict = {
"business": ...,
"amount": ...,
...,
# Pass any information you want HERE!
"custom": request.order.order_number,
}
form = PayPalPaymentsForm(initial=paypal_dict)
context = {"paypal_form": form}
return render(request, "payment_paypal.html", context)
<强> payment_paypal_ipn_signal_handler.py 强>
def payment_paypal_ipn_signal_handler(sender, **kwargs):
ipn_obj = sender
# Retrieve the order_number previously passed
order_number = ipn_obj.custom
# Get the order :D
order = Orders.objects.get(order_number=order_number)
...
在处理IPN信号的视图中检索订单号(或其他信息)。
