Django SocketIO Connection Fails After RDS Restart – How to Handle Database Connectivity Issues?
I'm developing a Django application using SocketIO for real-time communication, and I'm encountering an issue where SocketIO connections fail after an RDS (Relational Database Service) restart, while my Django HTTP APIs continue to work fine. Problem Description My Django application integrates with SocketIO for real-time features. After an RDS instance restart, the HTTP APIs function normally, but SocketIO connections encounter issues and fail to access database models. Specifically, I get errors related to database connectivity when attempting to handle SocketIO connections. Code Snippets Here's how I configure my ASGI application and handle SocketIO connections: ASGI Configuration (asgi.py): import os from django.core.asgi import get_asgi_application import socketio from backend.socketio import socketio_server os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'backend.settings.dev') django_asgi_app = get_asgi_application() application = socketio.ASGIApp(socketio_server=socketio_server.socketio_server, other_asgi_app=django_asgi_app) SocketIO Connection Handler: async def on_connect(self, sid: str, environ: dict): try: query_string = environ['asgi.scope']['query_string'] token, chat_id = get_token_chat_id_from_query(query_string=query_string) if not token or not chat_id: raise ConnectionRefusedError("Invalid connection parameters.") user = await get_user_from_token(token=token) chat_obj = await get_chat_from_id(chat_id=chat_id, user=user) await update_all_chat_redis(chat_obj=chat_obj) async with self.session(sid=sid, namespace=self.namespace) as session: session['user_id'] = user.id session['chat_id'] = chat_obj.machine_translation_request_id await self.enter_room(sid=sid, room=chat_id) except ConnectionRefusedError as e: logger.error(f"Connection refused: {e}") raise except UserErrors as exc: logger.error(f"User error: {exc.message}") raise ConnectionRefusedError(exc.message) except Exception as e: logger.error(f"Unexpected error: {e}") raise ConnectionRefusedError("An unexpected error … -

DRF Response field shows List of String with backslashes
I'm creating Polls feature using DRF where users can create a poll. The Response object in postman for the 'options' field shows the List of strings with backslashes.

Django Grappelli Custom Dashboard not showing App Models
Django 5.0.1 & Grappelli v4.01 Have site running on local runserver host and the custom dashboard works as expected. Site has been pushed to Azure as an App Service. The custom dashboard only shows the Groups, Sites and Users Models from auth. I am logging in as a superuser in both cases and both the local runserver and app service instances are pointed to the same backend database on Azure. I suspect permissions but not sure why the core models appear but the app based ones don't on the App Service. What am I missing? thanks in advance. -

How should I learn Django? [closed]
I have tried learning Django in the way I was learning Flask. Looking into documentation and googling phrases like 'Django user', but I find it a lot harder to get what I want. Google shows me links to documentation where there is some info about the topic and a lot of information about anything related. For example when I tried looking for how to implement User model to project I found django.contrib.auth.models - User and links to authentication, but a bit later looking for some examples I found AbstractUser, which I didn't see on the page of documentation I were on... so my question is how should I learn Django? Should I follow some tutorials instead of what I am doing now (trying to make a webpage along learning from documentation)? What is the best way to learn Django? -

Join tables and retrieve columns in Django

I want to write a join: SELECT mt.child_id, mt.child_qty, ct.name, ct.property FROM mapping mt, child ct WHERE mt.parent_id = 1; that gives result: child_id child_qty name property 1 5 name1 prop1 2 3 name2 prop2 4 4 name4 prop4 I wrote this: my_qs = Mapping.objects.select_related('child').filter(parent_id=1).values() print(my_qs) # [{'id':1, 'parent_id': 1, 'child_id': 1, 'child_qty': 5}, # {'id':2, 'parent_id': 1, 'child_id': 2, 'child_qty': 3}, # {'id':3, 'parent_id': 1, 'child_id': 4, 'child_qty': 4}] What do I modify in my ORM query so that: I don't see 'id' and 'parent_id' in the output I see 'ct.name and ct.property' in the output (with our without 'ct.' prefix) -

Updating object attribute from database in Django
Let's say I have a model representing a task: class Task(models.Model): on_status = models.BooleanField() def run(self): # obj = Task.objects.get(id=self.pk) # self.on_status = obj.on_status if self.on_status: # do stuff I run this task with Celery and I have a dashboard running on Gunicorn both using the same database. app = Celery("app") app.conf.beat_schedule = { "run_task": { "task": "run_tasks", "schedule": 5.0, "options": { "expires": 6.0, }, }, } tasks = Task.objects.all() @app.task def run_tasks(): for task in tasks: task.run() I can change on_status from my dashboard, but then I need to update self.on_status of the instance inside Celery process. I could create a new instance with get() and read value from that, but it doesn't seem right. Is there a command to update attribute value from database or is there a different approach? -
