I can't find where is the the customer id when I receive an avent from Stripe webhooks after a transaction was made: @csrf_exempt def StripeWebhookView(request): CHECKOUT_SESSION_COMPLETED = "checkout.session.completed" payload = request.body sig_header = request.META["HTTP_STRIPE_SIGNATURE"] endpoint_secret='whsec_o0T4qLvSeI0kjhpUs2JcHq9F0Ik9VUeY' try: event = stripe.Webhook.construct_event( payload, sig_header, endpoint_secret ) if event["type"] == CHECKOUT_SESSION_COMPLETED: **customer_id_stripe = event["data"]["object"]["customer"]** print('customer_id:', customer_id_stripe) I have tried to fetch the customer id by using this line of code: **customer_id_stripe = event["data"]["object"]["customer"]** but when I print customer_id_stripe it print None and to be honest, when I check out the full object I recieved from Stripe this is what I get: { "id": "evt_1MqMKgESXHNK1nmVaYJeR1PX", "object": "event", "api_version": "2022-11-15", "created": 1679947678, "data": { "object": { "id": "cs_test_a1A15S4eEOZc3WPfyTT5aJeGhhXRi5DK8xQiRnbgs8iG16rZ8oN032V8rm", "object": "checkout.session", "after_expiration": null, "allow_promotion_codes": null, "amount_subtotal": 50, "amount_total": 50, "automatic_tax": { "enabled": false, "status": null }, "billing_address_collection": null, "cancel_url": "http://127.0.0.1:8000/discovery/", "client_reference_id": null, "consent": null, "consent_collection": null, "created": 1679947653, "currency": "usd", "custom_fields": [ ], "custom_text": { "shipping_address": null, "submit": null }, # **"customer": null,** "customer_creation": "if_required", "customer_details": { "address": { "city": null, "country": "IL", "line1": null, "line2": null, "postal_code": null, "state": null }, "email": "anon@gmail.com", "name": "asdasd", "phone": null, "tax_exempt": "none", "tax_ids": [ ] }, "customer_email": null, "expires_at": 1680034053, "invoice": null, "invoice_creation": { "enabled": false, "invoice_data": { "account_tax_ids": … -
When using Django's Prefetch object, it makes one query per related object
So I've been developing with Django for a while. I am familiar with prefetch_related and was noticing some strange behavior today when working with Prefetch objects. I was under the impression that a queryset executed with prefetch_related would make 2 queries, 1 for the parent objects, and another for the children filtering on the parent object ids. However, when I print the queries being executed using pretch_related with a Prefetch object, I noticed that one query was being made per related object which diminishes the desired effect of prefetch_related. Can anyone fill me in to why this is happening based on the following code and returned SQL. Schedule.objects.prefetch_related("shifts") # SQL returned [{"sql": 'SELECT "schedule"."id" FROM "schedule" LIMIT 21', "time": "0.033"}, { "sql": 'SELECT "shift"."id" FROM "shift" WHERE "shift"."shift_id" IN (1, 2) ORDER BY "shift"."order" ASC', "time": "0.062", } ] The above is what I expected Now the problem queryset Schedule.objects.prefetch_related( Prefetch( "shifts", queryset=Shift.objects.filter( state__in=[StopPointStates.COMPLETED, StopPointStates.PENDING] ) .order_by("assigned_at", "priority", "order") .only("id"), ) ).only("id") # SQL returned [{"sql": 'SELECT "schedule"."id" FROM "schedule" LIMIT 21', "time": "0.009"}, { "sql": 'SELECT "shift"."id" FROM "shift" WHERE ("shift"."state" IN (\'completed\', \'pending\') AND "shift"."shift_id" IN (1, 2)) ORDER BY "shift"."assigned_at" ASC, "shift"."priority" ASC, "shift"."order" ASC', "time": "0.015", … -

gdal required on django but why?
I imported 3 tables on to my postgresql. These tables have the names of countries, regions, cities and then IP to countries. They are pretty old but very exhaustive. In my models I have not created any geo field or any point field, the latitude and longitude were expressed as float fields and I did that precisely to avoid having to install libraries. Yet, when I was writing makemigrations, I got an error that I needed to install gdal library. Reluctantly I did, but then it asked me that I needed to install GLIBCXX_3.4.30 library. It turns out they are not available for Fedora. What is this lousy break? I am using Fedora 37 and I am pretty annoyed at this, because, why would django tell me that I have to install that? Has it detected that the tables in postgresql have city names, latitude and longitudes? they are expressed as float fields in the table cells. -

AJAX performs its function, but the page refreshes

What is difference between explicit pk and auto pk in Django, which one is preferred?
→ Shows warning when using auto pk. (Auto-created primary key used when not defining a primary key type, by default) → Problem get saved pk in explicit defined: 19 class Post(models.Model): 20 id = models.IntegerField(primary_key=True) 21 timestamp = models.DateTimeField(auto_now_add=True) 22 content = models.TextField(max_length=4096) 23 user = models.ForeignKey(User, on_delete=models.PROTECT, related_name="userPosts") The problem in: post = Post.objects.create( content = data.get("post"), user = request.user ) print(post.pk) Returns: None If comment line 20 above, Returns: 82 Why using auto-pk has warnings? While the explicit cant returns after saving the object? (Are there any solution?)
