Django 发送 API 请求最佳实践：内部模型保存还是序列化程序？

Question

I have a model called Customer , and in the model save method, I send a request to the Stripe API to create a customer whenever a customer instance is created on my application. Another way I could do it is in the serializer.py file. That is, when a user creates a Customer instance on my application, it will automatically send a request to stripe to create a customer on that end. Which of these is the better practice? I believe, for "updating" customers, I will have to send the request to stripe from my serializers.py file. So might as well do the create customer from that file too. Any help would be appreciated.

Answer 1

Your both approaches are correct either request Stripe in save method or after user creates a customer. And you don't need serializers for updating customers. Simply you can do this, just an example for updating card.

def update_card(request):
    if request.method == 'POST':
    """
        replace old card with new
    """

        customer = Customer.objects.get(user=request.user).stripe_cust_id
        # Customer is my custom table that recored stripe customer information

        stripe.Customer.modify(
            customer,
            source=request.POST['stripeToken'],
        )

my template

 <form action="{% url 'subscriptions:update_card' %}" method="post" id="payment-form">{% csrf_token %}
                            <div class="card-input-wrap m-4">

                                    <label for="card-element">Credit or debit card</label>
                                    <div id="card-element">
                                        <!-- a Stripe Element will be inserted here. -->
                                    </div>

                                    <!-- Used to display form errors -->
                                    <div id="card-errors" role="alert"></div>


                            </div>
                                <button type="submit" class="btn btn-primary ml-4 mb-4">Save Info <i class="la la-save"></i></button>
   </form>
