webrtc shows extra stream with only one peer connection
I am trying to allow my webrtc video call meeting app have multiple peer connections and have the stream appear on the remote video call dynamically using javascript. I have only two tabs in two windows open on the video test room url. One is incognito and one is regular google chrome browser but both are google chrome browsers. They are both logged in to superusers. The problem is, the remote videos are shown twice of the same user of the remote user.

Google OAuth 2.0: Login with Google works on localhost, but it doesn't work on hosting
I have a small Django website, and I've connected OAuth 2.0. It worked just fine on localhost. (In the Google Console, the authorized redirect URIs were: URI 1: http://127.0.0.1:8000/ URI 2: http://127.0.0.1:8000/google/login/callback/) Now I have moved the website to hosting and changed the URLs to: URI 1: https://yukkiewqr.eu.pythonanywhere.com/ URI 2: https://yukkiewqr.eu.pythonanywhere.com/google/login/callback/ However, when I'm trying to log in through Google, I see the following error: "Access blocked: This app’s request is invalid. You can’t sign in because this app sent an invalid request. You can try again later or contact the developer about this issue. Learn more about this error. If you are a developer of this app, see error details. Error 400: redirect_uri_mismatch." On my website, I am using the Django Framework and the AllAuth plugin to connect to Google. I would be very grateful if anyone knows how to fix it -
Why is my email template in Django sending the whole model and not just the values input
I'm trying to email a copy of my contact form when the form is saved, but the template tags seem to be pulling the full model not just the inputs. I have no idea what I'm doing wrong here. My email template.txt file Hi!

Asyncio coroutine execution stopped and didn't return any error
I'm facing an odd behavior on one of my applications. So I have an application that has an POST entrypoint that receives a list of order id's and after processing each order it must inform an external API about the monetary value of each order. So what we did was the following: round_details_tasks = [ asyncio.create_task( self.launch_individual_order_details(order), name=f"task_order_{order.id}", ) for order in active_orders ] results = await asyncio.gather(*order_details_tasks, return_exceptions=True) for task, result in zip(order_details_tasks, results): if isinstance(result, Exception): print(f"⚠️ Task '{task.get_name()}' raised an exception: {result}") else: print(f"✅ Task '{task.get_name()}' succeeded with result: {result}") The launch_individual_order_details(order) function does the following stuff and other non I/O logic before this block: logger.debug(f"Sending order details with success for order: {order.id}") await order_service.send_order_request(order) Inside send_order_request we create a entry on a table called Transaction with the order id and the corresponding order amount and in pending state and send http request using aiohttp.CLient library. Afterwards we update the transaction status to Success if the request response is succesful and to error if the request fails. So the problem we are facing is that when our system is with a relative amount of load in our pods when the pod uses 70% of the CPU limits … -
User getting added to multiple permission groups instead of the one
In my application, when a user registers, they are identified as either a lecturer or a student. These are categorised as auth_groups, and users are assigned to one with these methods... def register_student(self, data): user = User.objects.create( user_id = data["user_id"] ) students_group = Group.objects.get(name = "students") user.groups.add(students_group) return user def register_lecturer(self, data): user = User.objects.create( user_id = data["user_id"] ) lecturers_group = Group.objects.get(name = "lecturers") user.groups.add(lecturers_group) return user On the surface, this appeared to work fine, but when I went to write the test suite, the following issue occurred: When register_student is called, the user is added to both the lecturer and student groups in the line user.groups.add(students_group). I want to mention that "students" have more permissions than "lecturers". Why is this happening? Thank you for any help! -
How to Restart a Django App via API After Modifying settings.py?
I am working on a Django project where I dynamically add new languages via an API. The workflow is as follows: Add a new language via the API (http://localhost:8000/core/swagger/). Via API /generate/ Generate the .mo and .po files after adding the language. The new language is added to languages.json, which is loaded into settings.py at startup. To apply the new language, Django needs to be restarted. I have tried several approaches to restart Django automatically via an API: ✅ Clearing Django's cache before restarting. ✅ Using a .sh script to kill the process and restart Django. ✅ Manually stopping and restarting Django (this works fine manually, but not via the script). Issue: When calling the restart API, Django stops successfully but does not restart. The restart only works when I manually stop the server and restart it from the terminal. The script kills the PID but doesn’t properly relaunch Django. What I Need Help With: What is the best way to restart Django from within an API call? Is there a more reliable way to restart Django inside Docker as well? Why does manually stopping Django and then restarting work, but the script approach does not? Relevant Repo with explaination … -
Django - PostgreSQL docker - authentication issue
I've been trying to set up my first Django and PostgreSQL project with Docker containers. I followed this setup and everything went as expected: https://learndjango.com/tutorials/django-docker-and-postgresql-tutorial Opening my Django admin portal worked without any issues on: http://127.0.0.1:8000/admin/ However I also wanted to connect to my 'db' (via DBeaver or in the terminal). However, I keep getting this error: FATAL: password authentication failed for user "postgres" FATAL: password authentication failed for user "postgres" Does anyone have any experience with this issue? DBeaver connection docker-compose.yml settings.py I first tried to only have my PostgresQL database in docker and keep the Django project outside, locally. However, that was the first time I bumped into the issue of 'password authentication'. I figured it was because I didn't set up both the Django project and my PostgresQL in Docker containers. But unfortunately, adding both in Docker containers did not help. I also tried to: Change the pg_hba.conf authentication Method to 'host all all all md5' instead of 'host all all all scram-sha-256'. But that didn't do anything either. -

Embedding a Web Application Using an Iframe
I have a Django application (A), and one of my clients wants to embed it within their application (B) using an iframe. The client application can be built with any framework, and we have no control over its code. Additionally, both applications are hosted on entirely different domains. To enable this setup, we need to fine-tune the settings in our Django application A to allow embedding within client application B. Below is a test HTML code snippet used to embed the web application, which I have hosted using a free hosting service. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>URL Loader</title> <style> body { font-family: Arial, sans-serif; text-align: center; margin: 20px; } iframe { width: 100%; height: 80vh; border: 1px solid #ccc; } </style> </head> <body> <h2>Loaded URL in iFrame</h2> <iframe id="urlFrame" src="https:/xyz.com" ></iframe> </body> </html> Django Configuration: Python 3.6 Django: 2.2.5 Changes made: Updated Django settings to permit the domain to load the application.

Prevent Multiple Users from Booking the Same Table at the Same Time in Django
I have a Booking model where users can book a restaurant table for a specific date and time. However, I want to ensure that multiple users cannot book the same table at the same time. Here’s my model: class Booking(TimeStampWithCreatorModel, TerminalMixin, SoftDeletableModel): table = models.ManyToManyField(RestaurantTable, related_name="booking_table") customer = models.ForeignKey(Customer, on_delete=models.CASCADE, related_name="booking_customer") no_of_people = models.IntegerField() booking_date = models.DateField() booking_time = models.TimeField(null=True, blank=True) note = models.TextField(blank=True) accept_terms_and_conditions = models.BooleanField(default=False) receive_emails = models.BooleanField(default=False) class Meta: ordering = ("-created",) What I've Tried I attempted to use select_for_update to lock the rows while making a booking, but when multiple users try to book the same table at the exact same time, duplicate bookings are still created in some instances. Here’s the approach I used: from django.db import transaction def create_booking(customer, table_ids, booking_date, booking_time, no_of_people): with transaction.atomic(): tables = RestaurantTable.objects.filter(id__in=table_ids).select_for_update() if Booking.objects.filter(table__in=tables, booking_date=booking_date, booking_time=booking_time).exists(): raise ValueError("Table already booked for this time slot.") booking = Booking.objects.create( customer=customer, no_of_people=no_of_people, booking_date=booking_date, booking_time=booking_time ) booking.table.set(tables) return booking The Problem Despite using select_for_update, when multiple instances try to book at the same time, the check Booking.objects.filter(...) does not prevent race conditions properly. I assume this happens because Django’s ManyToManyField does not lock relationships the same way ForeignKey does. Expected Outcome Prevent … -

Django css not rendering in Production
In my Django5 app everything works fine in development under venv but once I load the application into a Docker container with Debug=False I don't seem to get my CSS rendered properly. Whats really wierd is the CSS loading appears to be correct, I just don't get my custom css hero image and colors, and the admin css is also broken. I'm using gunicorn with nginx serving static data. I do see my favicon.ico which is served from the same /static/ folder and the css, js, etc. folders all exist in the nginx container as expected.

How to Implement Media File Upload Limits and Through Models in Django API for Large Real Estate File Management System?
I am building a large real estate file management system using Django API. I have created a separate app for media handling, and in my model, I want to enforce the following limits: A single featured image A gallery with a maximum of 10 images A maximum of 2 video uploads, each with a cover image A maximum of 2 music files A maximum of 2 PDF files For these, I've used a Through Model to connect the media model to the main model, such as a "listing" or "project" model. My question is: Should these upload limits be handled within the Django serializer, or is there a better approach? Is this the best way to connect models, especially when the main models might have multiple foreign keys? I’m concerned about performance and scalability. Since speed is critical and I need to connect media to models across multiple apps, what would be the most efficient way to implement these restrictions? Thanks in advance! my code : Model.py from django.db import models from django.core.validators import FileExtensionValidator import os from django.utils.translation import gettext_lazy as _ import uuid from django.core.exceptions import ValidationError from src.core.models.base import BaseModel def upload_media_path(instance, filename): ext = filename.split('.')[-1].lower() return … -
Why is my Django serializer returning only Match data and not including related Score data in the API response?
I'm working with Django REST Framework and trying to create an API endpoint that returns live match details along with their associated scores. I have two models, Match and Score, where Score has is associated with Match with a foreignkey. However, when I serialize the Match model, the response only includes match details and does not include any score information. Here’s what my serializers look like: class ScoreSerializer(serializers.ModelSerializer): class Meta: model = Score fields = ['id', 'run', 'wickets', 'overs'] class MatchSerializer(serializers.ModelSerializer): scores = ScoreSerializer(many=True, read_only=True) class Meta: model = Match fields = '__all__' Here is my view code: def livematch(request): live_matches = Match.objects.filter(match_mode='Live') serializer = MatchSerializer(live_matches, many=True) return Response({'success': True, 'data': serializer.data}) -
How to structure a Django DRF project for handling multiple tests and responses
I am working on a Django project using Django REST Framework (DRF), where I need to define a list of tests. Each test consists of multiple questions, and there are corresponding answers for those questions. My initial idea is to create an app called tests and use two CSV files: One CSV file containing all the questions for different tests. Another CSV file containing all the answers. However, I am concerned that this approach might make the code confusing and difficult to maintain. Questions: What is the best architecture for implementing this feature in Django DRF? Is storing test questions and answers in CSV files a good approach, or should I use models and a database instead? If there are any existing similar open-source projects on GitHub, could you provide references? I would appreciate any guidance or best practices on how to structure this project effectively. -
Chaining filter with django filter and django autocomplete light
I am trying to combine Django Filters (DF) with Django Autocomplete Light (DAL). I also want to chain the filter on a few fields in my model. For instance, before applying the DF to my model, I'd like to accomplish the following: Select a certain country. Filter all regions within the selected country. Filter all the cities within the selected region. I have implemented DF and DAL separately and have no issues, which indicates that my views are working as intended. Therefor I don't see any point to share the URLs. I can the see the following response in the console when manually testing DAL in another form: This means that the forwarding in DAL works. However, when I try DF together with DAL: I see that the dictionary values are not set. Which is correct because in the drop-down form I don't see any filtering. I can only auto complete my search for the country field. The region and city fields are not working properly. Views: class CountryAutoComplete(autocomplete.Select2QuerySetView): def get_queryset(self): qs = Country.objects.all() if self.q: qs = qs.filter(name__istartswith=self.q) return qs class RegionAutoComplete(autocomplete.Select2QuerySetView): def get_queryset(self): qs = Region.objects.all() country = self.forwarded.get("country", None) if country: qs = qs.filter(country=country) if self.q: qs … -
Django translation for uz-cyrl return uz instead
I have configured my django LANGUAGES like import os from django.utils.translation import gettext_lazy as \_ from config.settings.base import BASE_DIR LANGUAGE_CODE = "en" USE_I18N = True LANGUAGES = ( ("uz", _("Uzbek")), ("uz-cyrl", _("Cyrillic")), ("ru", _("Russian")), ("en", _("English")), ("ar", _("Arabic")), ) LOCALE_PATHS = [os.path.join(BASE_DIR, "locale")] I have translated texts in all .po files and compiled them. In local runserver it works with Accept-Language: uz-cyrl properly, but through docker-compose it returns uz translation instead, what might be the reason? I have used different base docker images like python3.11-slim, python3.11 itself but not worked.
