【问题描述】：

我正在使用 django 构建一个电子商务网站。一旦用户按下结帐，就会弹出一个 html 计费表单并提示用户输入地址、电子邮件等。

我还传递了电子邮件等数据，它运行良好。但是当我尝试它没有通过的金额时

我如何将金额传递给支付网关？

def CartView(request):

    cart = Cart(request)
    total = str(cart.get_total_price())
    total = total.replace('.', '')
    total = int(total)



    return render(request, 'payment/payment_form.html',)

【参考方案1】：

您没有将这些变量 total 和 cart 传递给模板上下文

改变这个

return render(request, 'payment/payment_form.html',)

到

return render(request, 'payment/payment_form.html', 'total': total, 'cart': cart)
