celery nested task (tasks inside tasks)
I wrote 2 update_all_rss task but don't know which one is better. can someone explain it which one should I use? Info: each task is independent and doesn't need other task result.

Inner funtion gives error in Django Rest Framework
I have inner functions inside the main function with an IF statement but when the if condition is applied it gives this error (AssertionError: The request argument must be an instance of django.http.HttpRequest, not rest_framework.request.Request.)

Django: set filter manager at runtime
My Django app stores the same sets of data for multiple different chat servers. Each model has a server as a ForeignKey to track which server the data is from. In my views.py, I have a bunch of manager/model functions like this: def index(request) context = { 'most_pinged': User.objects.get_most_pinged_user(), 'top_emojis': Emojis.objects.get_top_emojis(user1), 'top_channels': Channels.objects.order_by('-messages')[:10] } etc. The problem: I want to make it so that these functions only operate on the data of ONE server at a time, and filter out all of the data from other servers. I'd have to write a bunch of filters, like so: def index(request, server_id): context = { 'most_pinged':User.objects.get_most_pinged_user(from_server=server_id), 'top_emojis': Emojis.objects.get_top_emojis(user1, from_server=server_id), 'top_channels': Channels.objects.filter(server__id=server_id).order_by('-messages') } Is there any way to make it so that instead of having to write a bunch of filters for my manager methods and such, I can just have User/Emoji/Chnanel.objects filter out all of the other server's data from the get-go? Managers can be used to filter data, but not dynamically like this (afaik). I'm willing to be flexible! -
Unable to setup webhook for Whatsapp Cloud API
I am trying to configure my django app url as a webhook in Whatsapp Cloud API to receive messages. On setting up the webhook, the whatsapp sends a request to the url with certain parameters and we have to return one of them to verify our url and then it is added as webhook. The problem is my app's url is not receiving any request from whatsapp. The app is hosted on pythonanywhere. I hit the same url from my browser and its working fine. I ran the same code on my local machine using ngrok and try to set up the url as webhook and it received the request from whatsapp. Furthermore i tried another flask url on pythonanywhere on another account and it also received the request. Hence it's not an issue with code or pythonanywhere also the url is accessable from browser. I am really confused. -

Django: Validate DateTimeField based on another DateTimeField
I'd like to validate a DateTimeField based on another DateTimeField in the same mode, like so: class Operation(models.Model): machine = models.ForeignKey(Machine, on_delete=models.CASCADE) start = models.DateTimeField(auto_now_add=True) end = models.DateTimeField( null=True, blank=True, validators=[ MinValueValidator(start) ] ) I get a TypeError exception when POSTing: '<' not supported between instances of 'datetime.datetime' and 'DateTimeField' These are the variables: a datetime.datetime(2023, 1, 10, 0, 25, 29, tzinfo=zoneinfo.ZoneInfo(key='America/Sao_Paulo')) b <django.db.models.fields.DateTimeField: start> self <django.core.validators.MinValueValidator object at 0x104ded4d0> I suppose I need to extract the datetime.datetime from the field, but I can't seem to do it from inside the model validator. Any tips? Thank you. -
Detecting if a site is refreshed on a mobile phone
I developed this js code, that should detect when a site is loaded for the first time or is refreshed. I send this information tho a django view. The problem is that it works on PC but not on mobile devices like phones, tablets, etc... Here is the javascript code: window.addEventListener('load', function() { // Check if the page has been reloaded var isReloaded = sessionStorage.getItem('isReloaded'); if (!isReloaded) { // It's the first visit or a new session sessionStorage.setItem('isReloaded', 'true'); // Perform actions for the first visit here } // Send the reload information to the server var isRefreshed = isReloaded ? 'true' : 'false'; var csrfToken = '{{ csrf_token }}'; $.ajax({ type: "POST", url: '', data: { 'is_refreshed': isRefreshed, 'csrfmiddlewaretoken': '{{ csrf_token }}' // Include CSRF token for security }, dataType: 'json', success: function(data) { // Handle the response from the server here, if needed console.log(data.message); }, error: function(xhr, status, error) { // Handle errors here, if needed console.error(error); } });// Replace with your CSRF token // Make an AJAX request here to send 'isRefreshed' and 'csrfToken' to the server. }); -
Django TypeError: issubclass() arg 1 must be a class when trying to create a simple tag

Messing up the event handler in django, help me figure it out
My models: class Product(models.Model): name = models.CharField(max_length=255) owner = models.ForeignKey(User, on_delete=models.PROTECT, related_name='owner') allowed_users = models.ManyToManyField(User) def __str__(self): return self.name class Lesson(models.Model): name = models.CharField(max_length=255) link = models.URLField() time = models.PositiveIntegerField() products = models.ManyToManyField(Product) def __str__(self): return self.name class UserLessons(models.Model): user = models.ForeignKey(User, on_delete=models.PROTECT) lesson = models.ForeignKey(Lesson, on_delete=models.PROTECT) is_view = models.BooleanField(default=False) view_time = models.PositiveIntegerField(default=0) date_view = models.DateField(null=True) def __str__(self): return f'{self.user.username} - {self.lesson.name} I am implementing an event handler that should create a record in the DB when creating a Lesson record @receiver(post_save, sender=Lesson) def create_user_lessons(sender, instance, **kwargs): products = instance.products.all() allowed_users = [] for product in products: for user in product.allowed_users.all(): if user not in allowed_users: allowed_users.append(user) for user in allowed_users: UserLessons.objects.create(user=user, lesson=instance) But I came across the fact that instance.products.all() outputs an empty QuerySet, although it is not empty when creating a record. What is the reason for this behavior and how to solve it? I tried to redefine the save() method, but it didn't help in any way, but an important clarification appeared, instance.products.all() gives an empty qs only for the record that was created at the moment, the rest of the records work fully, when choosing another, everything is saved as needed -

DJANGO HTML Elements and Javascript
I'm trying to implement a "hover image" effect on a website drive by Django. Each model in my database contains 2 distinct images. I'd like to have the image change when the user hovers over the "default image" and have it change to the "hover image". What's happening instead is only the first image is changing to the hover image. If the user hovers over any other image on the page, the first image at the top of the page is the one that changes. Here's my HTML {% for element in records %} <div class = "model"> <img src="{{element.default_image}}" onmouseover="hoverImage();" onmouseout="defaultImage();" width="120"></div> Here's my JS const imgElements = document.querySelectorAll('.model'); for (let i = 0; i < imgElements.length; i++) { const currentElement = imgElements[i]; function hoverImage() { currentElement.src = '{{element.hover_image}}'; } function defaultImage() { currentElement.src = '{{element.default_image}}'; } } This only changes the first element in the model no matter what image the user hovers over -
Why don't frameworks like Django, Express and others often use class diagrams with UML?
Which software engineering and systems design tool to use in framworks like Django? I see that languages like Java, C# and C++ use UML class diagrams. But I don't see it in Python and Javascript.

Response times long for multiple users in Cloud Run for a Django application
I have a Django Rest Framework application which is hosted in Cloud Run. The normal response times for requests are around 100-200ms but no matter what I try I cannot get the same response times for multiple users. I have conducted load testing with Jmeter: for 200 users the best I can get is 1500ms average response time and for 500 around 4000ms (these are for "hot" instances). I have tried setting different values for gunicorn workers and thread (such as setting the max concurrency the same as # of cores * # of threads and setting the workers count the same as the number of CPUs and 2 * # of CPUs + 1) as well as trying with different CPU, memory and max instances and concurrent requests settings. I also checked that the Cloud SQL has sufficient CPU. What could be the bottleneck here? -

Django HttpResponseNotFound Not Displaying Correctly in View
I am working on a Django project where I have a view called 'chapterPage' that is supposed to display a specific chapter. If the chapter with the given primary key (pk) doesn't exist, I want to return an HttpResponseNotFound response. However, I am encountering an issue where the "Chapter not found" is not being displayed when the chapter is not found. Code snippets: views.py: from django.http import HttpResponseNotFound from .models import Chapter def chapterPage(request, pk): try: chapter = Chapter.objects.get(id=pk) except Chapter.DoesNotExist: return HttpResponseNotFound("Chapter not found") urls.py: urlpatterns = [ path("chapter/<str:pk>/", views.chapterPage, name="chapter"), ] The chapter link on the other webpage: <div> <a href="{% url 'chapter' chapter.pk %}">{{chapter.number}}</a> </div> I made sure that the chapter exists in the database with the intended pk. Also, when I'm trying to search for a chapter using the URL 'http://127.0.0.1:8000/chapter/5933/' the terminal returns 'Not Found: /chapter/5933/m' or 'Not Found: /chapter/5933/n', basically an intended URL with a random character afterward. I am expecting to get HttpResponseNotFound("Chapter not found") if the chapter is not found. P.S. I have just started learning so any help is apreciated! -
