Stripe; Webhook that triggers when the current subscription gets ended (not cancelled)
I know that there is a webhook type customer.subscription.deleted that gets triggered when a user cancels the subscription (that is they don't want the subscription to be auto-renewed after it ends) so at this webhook event, we just update the users subscription state to cancel but they still have the subscription active (and that is expected) but is there any webhook event that gets triggered when the subscription ends or we have to do that manually? I saw this webhook event but i'm not sure if this is the one I'm searching for subscription_schedule.completed Any guidance would be helpful, thank you :) -
Display the number of comments of each post related to the same post in django
Hello friends I am building a blog and I have encountered a problem. My problem is that when I want to display the number of comments for each post, on the main page of the blog number of comments displays all posts that have comments, but the number of comments for each post is the same. In the event that post 2 has 3 comments and the other has 1 comment. You can see in this picture. Image This is my models.py class Comment(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE) name = models.CharField(max_length=100) email = models.EmailField() comment = models.CharField(max_length=500) active = models.BooleanField(default=False) created_date = models.DateTimeField(auto_now_add=True) def __str__(self): return "{} by {}".format(self.comment, self.name) This is my views.py def post_list(request): posts = models.Post.objects.filter(status='published') paginator = Paginator(posts, 4) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) comment_count = models.Comment.objects.filter(active=True).count() context = { 'page_obj': page_obj, 'comment_count': comment_count, } # print(posts) return render(request, "post_list.html", context=context) And this too post_list.html <article class="col-12 col-md-6 tm-post"> <hr class="tm-hr-primary"> <a href="{{ post.get_absolute_url }}" class="effect-lily tm-post-link tm-pt-60"> <div class="tm-post-link-inner"> <img src="/{{ post.image }}/" alt="Image" class="img-fluid"> </div> <h2 class="tm-pt-30 tm-color-primary tm-post-title">{{ post.title }}</h2> </a> <p class="tm-pt-30"> {{ post.body|slice:254 }} </p> <div class="d-flex justify-content-between tm-pt-45"> <span class="tm-color-primary">Travel .

I have almost 10 million rows of data for Model1 and Model2, I'm not sure if it related to the issue but maybe it could help. -
Django raises set-returning functions are not allowed in WHERE with annotated value
I need to query orders where the shipping address's postcode is between a certain range. In order to do this, I have to cast the postcode (charfield) to a integer by removing the non numeric values. I have written this database function for that which works: class NumericPostcode(models.Func): """ Removes characters from field and converts to integer """ function = "REGEXP_MATCHES" template = "CAST( (%(function)s(%(expressions)s, '\\d+'))[1] as INTEGER )" output_field = models.IntegerField() Then I do the following query: orders_qs = Order.objects.annotate( numeric_postcode=NumericPostcode(models.F("shipping_address__postcode")) ).filter(self.get_range_query()) The get_range_query is a method that builds a dynamic query: def get_range_query(self): """ Build the range query dynamically based on all postcode ranges linked to this transporter https://docs.djangoproject.com/en/dev/ref/models/querysets/#range """ query = models.Q() for postcode_range in self.postcode_ranges.all(): query |= models.Q(numeric_postcode__range=(postcode_range.min_postcode, postcode_range.max_postcode)) return query However, this query raises the error: NotSupportedError at /admin/shop/reports/ set-returning functions are not allowed in WHERE Without the .filter(self.get_range_query()), I can print the annotated field fine and it also works.

file.truncate doesn't clear file content
I'm using python and django for an application, and I have to stock informations in a text file. So I've done this : def write_in_file(data): stock_file = open(os.path.join(sys.path[0], "static/imported_data.txt"), "w") stock_file.truncate() stock_file.write(data) stock_file.close() It's working like I want and my file contains 'data'. But when I refresh the page, the content of the file is not cleared, and 'data' is rewrited at the end of the file. And when I print something to debug, I see that the function is called every time I refresh the page. The only time my file is properly cleared is when I modify the 'write_in_file' function. Does anyone know from where this might come from ? -

Order queryset based on condition from fields in different table
I have some resources that a user can subscribe to, for added advantages. My challenge is in sorting them, where the resources with subscriptions come first and the rest follow. Initially, the resources were stored like this. from django.db import models from django.utils import timezone class Entity(models.Model): has_subscription = models.BooleanField() created_at = models.DateTimeField(default=timezone.now) # other fields and I would sort them like this, Entity.objects.all()order_by("-has_subscription", "-created_at") which worked. I decided to move to a different way of storing it that would favor a time bound subscription. I came up with this. from django.db import models from django.utils import timezone class Entity(models.Model): created_at = models.DateTimeField(default=timezone.now) @property def has_active_subscription(self): if ( self.entity_subscriptions.filter( start_date__lte=timezone.now(), end_date__gte=timezone.now() ).count() > 0 ): return True return False class Subscriptions(model.Model): entity = models.ForeignKey( Entity, on_delete=models.CASCADE, related_name="entity_subscriptions", related_query_name="entity_subscription", ) start_date = models.DateTimeField() end_date = models.DateTimeField() How can I sort the queryset in such a manner that the resources with subscriptions come first. -

I was following a YouTube tutorial about how to connect my django backend to Swift and when I finished following along, I just get a blank grey area where the phone preview should be. Anyone know why this would happen? Here's my Model file and my View. import Foundation struct Account: Codable, Hashable { var email: String var username: String var first_name: String var last_name: String var is_venue: Bool var date_joined: Date var last_login: Date var is_active: Bool var is_admin: Bool var is_superuser: Bool } And View import SwiftUI struct AccountView: View { @State var accounts = [Account]() var body: some View { ForEach(accounts, id: \.self) {item in HStack { Text(item.first_name) } }.onAppear(perform: loadAccount) } func loadAccount() { guard let url = URL(string: "http://127.0.0.1:8000/api/account/") // URL is the endpoint of API else { print("API is down") return } var request = URLRequest(url: url) request.httpMethod = "GET" request.addValue("application/json", forHTTPHeaderField: "Accept") request.addValue("Basic amZsb3JlbmNlMEBnbWFpbC5jb206QmEka2V0YmExMUZsMEppbW15ITEh", forHTTPHeaderField: "Authorization") URLSession.shared.dataTask(with: request) { data, response, error in if let data = data { if let response = try? JSONDecoder().decode([Account].self, from: data) { DispatchQueue.main.async { self.accounts = response } return } } }.resume() } } struct AccountView_Previews: PreviewProvider { static var previews: some View { AccountView() } }
