Websocket not receiving messages from Django Channels
I'm currently working on a project using Django Channels for WebSocket communication. However, I'm facing an issue where the WebSocket connection is established successfully, but messages are not being received on the client side. WebSocket connection is established without errors. I've verified that the Django Channels server is sending messages. However, the client-side WebSocket does not seem to receive any messages my asgi.py import os from django.core.asgi import get_asgi_application from channels.routing import ProtocolTypeRouter, URLRouter from channels.auth import AuthMiddlewareStack from channels.security.websocket import AllowedHostsOriginValidator import transposys_main.routing import django os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'transposys_main.settings') django.setup() application = ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": AllowedHostsOriginValidator( URLRouter( transposys_main.routing.websocket_urlpatterns ) ), }) consumer.py import json from channels.generic.websocket import AsyncWebsocketConsumer import logging logger = logging.getLogger(__name__) logger.setLevel(logging.DEBUG) class DepartmentCreatedConsumer(AsyncWebsocketConsumer): async def connect(self): logger.info(f"WebSocket connected: {self.channel_name}") await self.accept() async def disconnect(self, close_code): logger.info(f"WebSocket disconnected: {self.channel_name}") async def receive(self, text_data): logger.info(f"WebSocket message received: {text_data}") try: text_data_json = json.loads(text_data) message_type = text_data_json.get('type') message = text_data_json.get('message') if message_type == 'department.created': logger.info(f"New Department: {message}") except json.JSONDecodeError as e: logger.error(f"Error decoding JSON: {e}") async def department_created(self, event): try: logger.info(f"Department created event received: {event['message']}") await self.send(text_data=json.dumps({ 'type': 'department.created', 'message': event['message'], })) except Exception as e: logger.error(f"Error sending WebSocket message: {e}") routing.py: from django.urls import re_path from .consumers import DepartmentCreatedConsumer websocket_urlpatterns … -

Django: Implementing fund reversal in post_save signal
I'm using django post_save signal to update the status of a transaction based on whether funds are received. The problem is that funds_received is not working as expected. The issue is in using .exists(), because, it checks if there is any account with the exact balance equal to the transaction amount. If anyone has suggestions or knows of a better way for checking if funds are received, I would greatly appreciate the guidance. from django.db.models.signals import post_save from django.dispatch import receiver from .models import Transaction, Account @receiver(post_save, sender=Transaction) def transaction_status(sender, instance, created, **kwargs): if created: amount = instance.amount sender_account = instance.sender.account receiver_account_number = instance.account_number receiver_account = account.objects.get(account_number=receiver_account_number) check_if_funds_received = Account.objects.filter(account_balance=amount).exists() funds_received = check_if_funds_received if funds_received: instance.status = 'Reversed' instance.save() else: instance.status = 'Reversed' instance.save() # return funds to sender sender_account.account_balance += amount sender_account.save() My Models: class Account(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) account_number = models.BigIntegerField(unique=True) account_balance = models.DecimalField(max_digits=12, decimal_places=6) account_id = models.CharField(max_length=15, unique=True) user_qrcode = models.ImageField() first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) account_status = models.CharField(max_length=50, choices=ACCOUNT_STATUS) pin = models.CharField(max_length=4) def __str__(self): return str(self.user.first_name) class Transaction(models.Model): STATUS = ( ('Success', 'Success'), ('Reversed', 'Reversed') ) sender = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='sender') receiver = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='receiver') amount = models.DecimalField(max_digits=12, decimal_places=6) account_number = models.BigIntegerField() first_name … -
stocks quantity only decreasing not increasing
after updating the data, the stocks. Quantity is only decreasing does not matter if we only increase the quantity or decrease the quantity. I want when we update the data the stocks quantity will also be updated for ex-, we increase 2 points then only 2 quantities will be decreased. suppose we have 5 unit of shoes in cart and stocks have 10 quantities left so if we increase 2 so the total quantity will in cart 7 and left quantity in stocks will be 8 quantity shoes and if we decrease 3 quantities so the total quantity in cart will be 4 and total quantity in stocks are 11. for ex-, we increase 2 points then only 2 quantities will be decreased. suppose we have 5 unit of shoes in cart and stocks have 10 quantities left so if we increase 2 so the total quantity will in cart 7 and left quantity in stocks will be 8 quantity shoes and if we decrease 3 quantities so the total quantity in cart will be 4 and total quantity in stocks are 11.

POST data not registering in Django custom admin action with intermediate form
I am trying to add a custom admin action do my Django model. The goal is to show a form to the user where they can select a group which will get linked to all my selected candidates.

How to join multiple models with OnetOne relationship in Django?
I have a main model with several fields and a few other models that serve as extra information which varies depending on user input. The main model will always be related to one of these. I want to retrieve all the information between the main models and the models with extra information. Here's an example of the relationship: class MainModel(models.Model): MAIN_MODEL_CHOICES = [(1, "Extra info 1"), (2, "Extra info 2"), (3, "Extra info 3")] name = models.CharField(max_length=100) description = models.CharField(max_length=100) choice = models.IntegerField(choices=MAIN_MODEL_CHOICES) class ExtraModel1(models.Model): main_model = models.OneToOneField(MainModel, on_delete=models.CASCADE) extra_text_info = models.TextField() class ExtraModel2(models.Model): main_model = models.OneToOneField(MainModel, on_delete=models.CASCADE) important_number = models.IntegerField() class ExtraModel3(models.Model): main_model = models.OneToOneField(MainModel, on_delete=models.CASCADE) important_bool = models.BooleanField(default=False) I have tried MainModel.objects.prefetch_related("extramodel1", "extramodel2", "extramodel3") and MainModel.objects.select_related("extramodel1__main_model", "extramodel2__main_model", "extramodel__main_model") but the retrieved queryset doesn't include the extra models, only the main one. -
Celery Tasks not Running on Mac M2 (Process 'ForkPoolWorker' exited with 'signal 11 (SIGSEGV)')
I am encountering an issue while trying to run Celery tasks on my Mac M1 machine. The error message I'm getting is as follows: The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec(). Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__() to debug. [2023-11-20 15:51:19,174: ERROR/MainProcess] Process 'ForkPoolWorker-8' pid:5547 exited with 'signal 11 (SIGSEGV)' I am using Celery for my Django app task processing, and this issue seems to be related to forking on the M2 architecture. I initially attempted to resolve the issue by exporting OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES, which seemed to work for a brief period. However, the problem has resurfaced, and this solution no longer has any effect. It's worth noting that I am currently running MacOS Sonama 14.2 Beta on my machine. Interestingly, I encountered and successfully resolved this problem once before while on the same beta program. Any insights or suggestions on how to resolve this issue would be greatly appreciated. -

Django does not load the maps in the admin panel
I need to upgrade the Django version of a project that uses GeoModelAdmin for displaying maps in the admin panel. The recommended class to be used is ModelAdmin as stated in the documentation: Deprecated since version 4.0: This class is deprecated. Use ModelAdmin instead. However, when I use ModelAdmin the maps do not load at all. And I get this error in the console: GET https://gitc.earthdata.nasa.gov/wmts/epsg3857/best/BlueMarble_ShadedRelief_Bathymetry/default/%7BTime%7D/GoogleMapsCompatible_Level8/8/92/146.jpg 500 (Internal Server Error) Is there a configuration that I missed or there are problems with the server? In the past I used OSMGeoAdmin which was exactly what I needed, but got it deprecated in Django 4.0. Now is suggested to use GISModelAdmin instead. When I use GISModelAdmin the maps are loaded, but I want to configure the zoom level and if I set the gis_widget_kwargs according to the documentation, nothing changes. gis_widget_kwargs = { "attrs": { "default_lon": 5, "default_lat": 47, "default_zoom": 3, } } -

The problem is that all the script logic only works if I open a specific page. That is, I opened the “Camera1” page, saw the video stream from it and the script detects and counts the objects in the frame. If I open "Camera2" - the same. I need these scripts to work even when the page is not open. That is, for example, after rebooting the server, the Django application is automatically launched and, as it were, the opening of all pages from the cameras is simulated so that the scripts start working. In a word, I need the script to work even if it is not called directly on the page. Is this possible and if so - how? Thank you -
