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
When trying to create a simple tag in django to reassign a variable in a django template, I am getting the error TypeError: issubclass() arg 1 must be a class. custom_templates.py: from django import template register = template.Library() @register.simple_tag def define(val=None): return val part of my settings.py: ...

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 -

External database in django Admin Panel

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. How then to architect these systems? I've been searching for a approach to deal with django project with UML tools, but without success. Keep in mind that I'm a beginner in Django. -
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! -

Django threaded comments (MPTT) optimization issue
I'm using MPTT model to build a nested comments system in my Django Rest project. Everything works so far but I experience a huge performance issue when querying a database for API response. The schema of comments layout: Root Comment / \ Comment Comment / \ Child Child Whenever I'm querying all comments as an array in API response recursively: { "comments": [ { "id": 1, "children": [ "id": 4, "children": [ "id": 5, "children": ... ] ] } In this case even with "prefetch_related" and "select_related" I'm getting over 50 queries for 2 parent(root) comments (which have children comments and so on). Is there an efficient way to optimize this query?

What options are available for performance tuning a soundx query?
I was recently asked about improving website performance for a peers website. What options are typically used for performance tuning sites enabled with Soundx? Overview Using the homophones Smith/Smythe, I was able to reproduce the behavior of the website query response time described. These are measured at the browser so there's a lot that could go into the number, but generally speaking the values were what we would expect, less for the non-Soundex search and more for Soundex search.

Using django_debug_toolbar alongside drf_spectacular
