Django/Whitenoise collectstatic causing Permission Denied Error
I have been struggling with this for weeks and have hit a brick wall. Im trying to deploy a Django App and Im using Whitenoise to handle Static Data. When I run collectstatic I get “Permissions Denied” Error. How do I run collectstatic so that it can run without Permission problems. Django is installed in a virtualenv so running it as sudo doesn’t work. The error happens when using Whitenoise to handle static file using collectstatic when DEBUG is True or False and whether I use the Whitenoise STATICFILES_STORAGE or the Django version. $ python3 manage.py collectstatic “ File "/home/artillery/a1_lounge/web_dev/webdesign_biz/Portfolio/React/Vite/django/.venv/lib/python3.10/site-packages/django/core/files/storage/filesystem.py", line 106, in _save fd = os.open(full_path, self.OS_OPEN_FLAGS, 0o666) PermissionError: [Errno 13] Permission denied: '/home/artillery/a1_lounge/web_dev/webdesign_biz/Portfolio/React/Vite/django/hotdog/staticfiles/admin/js/admin/RelatedObjectLookups.js'” settings.py INSTALLED_APPS = [ 'hotdog_app', 'corsheaders', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'whitenoise.runserver_nostatic', # Whitenoise serves static in Dev and Prod 'django.contrib.staticfiles', ] MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', # Enable Whitenoise 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_STORAGE = "whitenoise.storage.CompressedManifestStaticFilesStorage" Normally creating a file will give standard permissions eg (.venv) $ touch test.txt -rw-rw-r-- 1 artillery artillery 0 Nov 8 13:00 text.txt On first run of collectstatic (.venv) $ python3 manage.py collectstatic PermissionError: [Errno 13] Permission denied: … -

How do I keep persistent web socket connections with another API in my Django app?
I'm developing a Django application that requires a persistent WebSocket connection to continuously fetch live data from a crypto market API. I need to keep this WebSocket connection active throughout the application's lifecycle to update my local data as new information arrives. This updated data will later be displayed on the front end, so I anticipate needing a separate WebSocket connection between the front end and back end (one connection for backend-to-crypto market API, and another for backend-to-frontend). I'm new to this type of setup and would appreciate guidance on the best practices for implementing it. I've explored Django Channels, Uvicorn, and Daphne. Although Django Channels might be suitable for the frontend-backend WebSocket connection, I'm more focused on maintaining a robust event-loop structure for the backend-to-crypto API connection to ensure it remains alive and responsive. I'm considering building a custom event-loop manager to handle this, but I'm unsure if it's the best approach. Could you suggest any established methods, libraries, or patterns for maintaining a continuous WebSocket connection for real-time data updates in a Django application? Thank you in advance! -
How to handle pre-selection of related fields and ensure proper update of many-to-many relationships in Django REST Framework?
I am working on implementing a Role-Based Access Control using Django and Django Rest Framework. I want to create a role with a set of permissions through the DRF browsable API. Additionally, I need the functionality to update those permissions, including adding new ones and removing existing ones. When displaying a role in the browsable API, I want the associated permissions to be pre-selected for clarity, while also showing all other available permissions for easy addition.

Multi tenant structure where frontend is custom domain : Cookies set as thirdparty
For some context - using django on backend and nextjs on frontend. On frontend, there is option to connect custom domains. When backend saves a session cookie in the browser, it is set as a third-party cookie (even though it is for/from the same service) Now chrome does not allow third party cookies in incognito which breaks my flows in incognito window. Is there a way around this using the existing system? OR Will I have to implement this on my own? Thanks in advance -

Django: the Celery signal, Redis Channel and AsyncWebsocket stack is not working

having generic fields based on model objects in forms.py in django

Sending messages to all user's devices with django channels
I have been developing project. It uses django channels for websockets. And I meet a problem with sending ws messages to all device of the same account that is logged in. It is not a rare situation when many users use same accounts while project is under developing. So when one user is logged in and the other user is logged in and then he is logged out the first user does not receive messages. I tried to count devices but that method changes nothing. My consumer is: class NotificationConsumer(AsyncWebsocketConsumer): def __init__(self, *args, **kwargs): super().__init__(args, kwargs) self.user = None self.pool_name = None async def connect(self): self.user = self.scope["user"] self.pool_name = f"user_id_{self.scope['url_route']['kwargs']['user_id']}" await self.accept() # Join pool created = await self.add_online_user() if created: await self.channel_layer.group_add( self.pool_name, self.channel_name, ) async def disconnect(self, close_code): # Leave room group removed = await self.remove_online_user() if removed: await self.channel_layer.group_discard(self.pool_name, self.channel_name) # Receive message from WebSocket async def receive(self, text_data): text_data_json = json.loads(text_data) message = text_data_json["message"] # Send message to room group await self.channel_layer.group_send(self.pool_name, {"type": "read_message", "message": message}) # Receive message from room group async def notification_message(self, event): message = event["message"] await self.send(text_data=json.dumps({"message": [message]}, ensure_ascii=False)) @database_sync_to_async def add_online_user(self): online_user = OnlineUser.objects.filter(user=self.user).first() if not online_user: OnlineUser.objects.create(user=self.user, counter=1) return … -
Eager vs Lazy Loading: Best Data Fetching Strategies for Large-Scale Web Apps?
I'm building a large-scale web app with Django in Python (I might switch to Flask), and I'm trying to optimize how I fetch data. Specifically, I’m debating between eager loading (fetching all data upfront) and lazy loading (fetching data on-demand) for large datasets with complex relationships (e.g., nested data, foreign keys). My main challenges are over-fetching (retrieving too much data upfront), N+1 query problem (multiple unnecessary queries), user perceived latency (delays in loading data). What are the trade-offs between these approaches, and how can I decide when to use one over the other? Any tips on optimizing data fetching for performance while handling large volumes and real-time updates? TL;DR: How do you decide when to use eager vs lazy loading for large-scale apps with complex data and real-time updates? -

Django IntegrityError: Unique Constraint Violation
I'm working on a Django project using Django Rest Framework (DRF) and PostgreSQL, with a Scan model that tracks different phases of a label scan. I've set a unique constraint on the combination of label_id and phase fields to prevent duplicate scans for the same label in the same phase.

My nginx site config is as follows: server { listen 80; server_name 10.4.0.189; root /home/wagtail/apps/my_site; charset UTF-8; error_log /home/wagtail/apps/my_site/nginx-error.log; location = /favicon.ico {access_log off; log_not_found off;} location static/ { root /home/wagtail/apps/my_site/; } location / { proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://unix:/run/gunicorn.sock; } } I have tried multiple block location configurations including alias.

Problem with user authentication in django
For a reason unknown to me, when authenticating a user, I enter the following data: email and password, as a result, super users are authenticated, but ordinary users are not.
