如何在 Django 中将多个参数传递给 url

Question

HTML 页面有 2 个按钮来处理付款，我需要将 2 个参数传递给 url 是有原因的。以下是我尝试过但不起作用的方法。有人可以帮我吗..？

<a href="{% url 'process-payment' order.id button.id %}"   id = "CashOnDelivery" class="btn btn-warning"> Cash on Delivery</a> 
<a href="{% url 'process-payment' order.id button.id %}"  id = "Card" class="btn btn-warning">Pay through Card</a>

views.py

def process_payment(request, order_id, button_id):
    if id == CashOnDelivery
     # directly take order
    return redirect (reverse('update-records', kwargs={'order_id': order_id}))

    else 
     # process the card payment then update transaction 
    return redirect (reverse('update-records', kwargs={'order_id': order_id}))

urls.py

urlpatterns=[
 path('payment/<order_id>/<button_id>',views.process_payment, name='process-payment'),
]

Answer 1

这是因为你的变量没有定义。

<a href="{% url 'process-payment' order.id 'CashOnDelivery' %}" id = "CashOnDelivery" class="btn btn-warning"> Cash on Delivery</a>.

<a href="{% url 'process-payment' order.id 'Card' %}" id = "Card" class="btn btn-warning">Pay through Card</a>.

另外你似乎没有检查正确的 ID。

def process_payment(request, order_id, button_id):
    if button_id == CashOnDelivery
     # directly take order
    return redirect (reverse('update-records', kwargs={'order_id': order_id}))

    else 
     # process the card payment then update transaction 
    return redirect (reverse('update-records', kwargs={'order_id': order_id}))```
