Overriding Save but database is not updated
I have a model, containing a save overide, that uses a function to set whether a sync is required based on a comparison of dates. The save is called by update_or_create which is in turn called by a management command For the purposes of debugging this issue sync_required is set to True regardless. class Site(models.Model): # LastEditDate & LastEditTime LastEditDate = models.DateField(blank=True, null=True) LastEditTime = models.TimeField(blank=True, null=True) ... # System Specific date_modified = models.DateTimeField(auto_now=True, null=True) last_synced = models.DateTimeField(blank=True, null=True) sync_required = models.BooleanField(blank=False, null=True, default=False) # Function to calculate if sync required. def is_sync_required(self): ... return True def save(self, *args, **kwargs): self.sync_required = self.is_sync_required() logger.info( f"Site/Save: LED:{self.LastEditDate}, LET:{self.LastEditTime}, DM:{self.date_modified}, LS:{self.last_synced} = SR:{self.sync_required}") super(Site, self).save(*args, **kwargs) In full operation the method is producing the correct output: A001 Site/is_sync_required/Return for A001= True with MinutesSince>=0 84659.0 Site/Save: LED:2024-02-29, LET:09:06:04.174000, DM:2024-09-27 08:19:27.430154+00:00, LS:2024-01-01 14:06:28+00:00 = SR:True A002 Site/is_sync_required/Return for A002= False with MinutesSince<0 -25449.0 Site/Save: LED:2024-08-14, LET:16:51:17.732000, DM:2024-09-27 08:20:33.720193+00:00, LS:2024-09-01 08:00:00+00:00 = SR:False A003 Site/is_sync_required/Return for A003= True with last_synced_none None Site/Save: LED:2024-09-02, LET:08:25:50.232000, DM:2024-09-27 08:18:35.456365+00:00, LS:None = SR:True A004 Site/is_sync_required/Return for A004= True with MinutesSince>=0 51517.0 Site/Save: LED:2024-08-06, LET:09:43:40.257000, DM:2024-09-27 08:21:40.917783+00:00, LS:2024-07-01 14:06:28+00:00 = SR:True However, the result of sync_required is not being saved … -
How to test the websocket connection in django channels
I need to test the success of the websocket connection. When connecting, the query_string parameter is checked. If it is transmitted, the connection is allowed. If not, the connection is closed.

Django Static Files Not Loading from AWS S3 After Running collectstatic
I'm working on a Django project where I want to store and serve static files using AWS S3. I have followed the usual configuration steps and set up my settings.py to use S3 for static files.

Django Framework CSRF verification failed with 403 Forbidden error. Request aborted for non-HTML python script
I am using Django Framework with DRF to generate APIs at the backend. I am using python script as an standalone windows based application to retrieve and send data to the backend server which is Django. It is not HTML application and no Cookies are involved.

CSS styling for individual paths not working

How can I annotate my Django queryset with a count of related objects
I have 3 django models; Machine, Component, and Part. I am trying to annotate a machine queryset to include the count of unique parts used in that machine. In the example below, ps1 is used to make f1. ps1 and ps2 are used to make f2. f1 and f2 are used to make r1. Therefore, 2 unique parts are used to create r1 and this is the value I want to use to annotate r1. So far my code is outputting 3 in this case. # |------------+---------------------+----------------+--------------+--------------| # | machine | component | part | expected | result | # | | | | parts | parts | # |------------+---------------------+----------------+--------------+--------------| # | r1 | f1 | ps1 | 2 | 3 | # | | f2 | ps1 | | | # | | | ps2 | | | # |------------+---------------------+----------------+--------------+--------------| Part has a ManyToManyField of Component. Component has a ForeignKey to Machine. This is the function I am working with to try and accomplish this. def annotate_machine_query_with_num_parts(machine_query): count_subquery = ( Parts.objects.filter(pk=OuterRef("pk")) .annotate(count=Count("id", distinct=True)) .values("count") ) sum_subquery = ( Parts.objects.filter( Q(component__machine_id=OuterRef("pk")) ) .annotate(count=Subquery(count_subquery)) .values("count") .annotate(num_parts=Sum("count")) .values("num_parts") ) return machine_query.annotate(num_parts=Coalesce(sum_subquery, 0)) This works for many test cases but fails when a … -
Django in Azure - CSRF Errors for existing URL in CSRF_TRUSTED_ORIGINS list
Deployed as web app in Azure and added my custom purchased domain name, lets call it 'i-heart-java.com'. I added the URL into the ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS lists, both as https and http, including with extra 'www.' entries. App pulls up successfully on those URL's and my page works for the most part, except when logging into any part of the app ONLY WITH MY CUSTOM DOMAIN, otherwise login works fine with the azure default domain.

Neon branching with Django pytest
I want to use Neon’s branching feature to create a new branch (a copy of the main database branch on Neon) every time the test suite runs. In the project I’m working on, we use pytest-django, PostgreSQL as our database, and Django as the backend. Pytest allows specifying a live database for testing (pytest-django docs). I’ve been trying to dynamically create a branch and a compute endpoint using the Neon APIs (Neon API docs). My goal is to use the newly created HOST for the test run, but the tests always run in the test_[DEFAULT_DB_NAME]. Here’s what my conftest.py file looks like: @pytest.fixture(scope='session') def django_db_setup(): logger.info("Creating new test db branch") neon = NeonAPI(api_key=os.environ.get('NEON_API_KEY')) project_id = "project_id" branch = neon.branch_create(project_id=project_id) settings.DATABASES['default'] = { 'ENGINE': 'django.db.backends.postgresql', 'NAME': os.environ.get('PGDATABASE', ''), 'USER': os.environ.get('PGUSER', ''), 'PASSWORD': os.environ.get('PGPASSWORD', ''), 'HOST': 'soemthing', 'PORT': os.environ.get('PGPORT', '5432'), } But this does not seem to have any effect at all. -
django is displaying debug 404 page when DEBUG is False
My django app is not using custom 404 page or handler. In my local dev environment when DEBUG is False I get a standard 404 page but on my deployed app on Render.com I get the django debugging 404 page. I have verified that DEBUG is indeed False there. I don't understand at all how this could be happening. My site is otherwise working well so I know ALLOWED_HOSTS is correct, etc. This is really strange. I have no idea how to troubleshoot this further except maybe trying a different hosting provider. I am using CloudFlare but I don't see how that would affect this. -

Managing all modules imports in a single file in Python/Django project, while avoiding circular imports
I’m working on a Django project that has numerous imported modules across various files, sometimes totaling up to 50 lines of imports per page. To reduce cluttering, I created a single file, "imports.py", to centralize my imports. Here’s a brief example of what it looks like: from datetime import date, datetime from typing import Any, Callable, Optional, Final, Type, TypeAlias, cast, Iterable from functools import wraps from cryptography.fernet import Fernet from requests.auth import HTTPBasicAuth from requests.models import Response from PIL import Image, UnidentifiedImageError from smtplib import SMTPRecipientsRefused from dotenv import load_dotenv from django.db import models, IntegrityError ... # a lot more __all__ = [ 'datetime', 'Any', 'Callable', 'Optional', 'Final', 'Type', 'TypeAlias', 'cast', 'Iterable', 'wraps', 'Fernet', 'HTTPBasicAuth', 'Response', 'Image', 'UnidentifiedImageError', 'SMTPRecipientsRefused', 'load_dotenv', 'models', 'IntegrityError',......] Then, in other files, I import everything from imports.py like this: from bi_app.py.imports import * While I know this might be unconventional, I find it more organized. This method works well for external modules and also for Linters, but when I try to include imports for my own project files, I often run into circular import issues. My question is: Is there a way to combine all imports from my own files, into a single file without … -
How to view Parallels VM Django webserver from Mac Sequoia host browser?
I've been running a Django webserver in an Ubuntu VM using Parallels (Standard Edition Version 20.0.1) on my M2 Mac. python manage.py runserver 0.0.0.0:8000 I then view the website in Chrome/Safari/Firefox on my Mac OS, pointing the browser to the IP of the VM at port 8000. http://ip.of.ubuntu.vm:8000 It's always worked great. But yesterday I upgraded my MacOS to Sequoia 15.0. Now I can't see the website served from the VM in the host browser anymore. I've tried switching VM > Configure > Hardware > Network > Source from Shared Network to Default Adapter, and also to WiFi, but those did not help. I can ping the VM's IP from the MacOS in Terminal and it finds it. But the browser cannot see the website. Chrome tells me: This site can’t be reached http://ip.of.ubuntu.vm:8000/donate/ is unreachable. ERR_ADDRESS_UNREACHABLE I've restarted everything. That hasn't helped. As a workaround, I can, of course, view the site in Ubuntu. That works properly. But I'd like to be able to see it in the host Mac also. Any suggestions? Thanks in advance! -
Nginx Displays Default Page Instead of Django App When Using uWSGI
I'm trying to deploy a Django application using Nginx and uWSGI on a Linux system (WSL2), but I'm encountering an issue where Nginx serves its default page instead of my Django application. I've confirmed that uWSGI is running and my Django app is functional by itself. Here's my current setup: Nginx Configuration: server { listen 80; server_name localhost; charset utf-8; location / { include /etc/nginx/uwsgi_params; uwsgi_pass unix:/var/run/uwsgi.webapppackage/master.sock; } } uWSGI Configuration (uwsgi.ini): [uwsgi] chdir = /mnt/c/Python/WonderPasNavi/wonderpasnavi home = /mnt/c/Python/WonderPasNavi/wonderpasnavi/.venv wsgi-file = /mnt/c/Python/WonderPasNavi/wonderpasnavi/wsgi.py module = wonderpasnavi.wsgi:application logto = /mnt/c/Python/WonderPasNavi/wonderpasnavi/uwsgi-my_app.log master = true vacuum = true pidfile = /var/run/uwsgi.webapppackage/master.pid socket = /var/run/uwsgi.webapppackage/master.sock processes = 2 die-on-term = true touch-reload = /mnt/c/Python/WonderPasNavi/reload.trigger lazy-apps = true Symptoms: Nginx serves the "Welcome to nginx!" page instead of the Django app. uWSGI logs indicate it's running without errors. No relevant errors in Nginx logs. I've tried restarting Nginx and uWSGI, checking the symlink in /etc/nginx/sites-enabled/, and clearing browser cache but no success. Could there be a configuration issue I'm overlooking, or is there a specific setting required for Nginx to properly forward requests to uWSGI? Any suggestions or guidance would be greatly appreciated! -

How do I maintain connection between Docker containers while having one of them connected to host machine?
I am currently deploying an application with Docker (version 27.2.1), using docker compose on debian 11. My docker-compose.yml file consists in defining 4 containers (app, api, db and ngninx). app and api are Django applications. db is a postgresql service. The whole is deployed on a machine that hosts an SMTP service on port 25. My Django app app needs to use this service to send emails to the users, but it also has to be able to connect with the other containers. For example, db is the host of the postgresql server that contains all the data managed by the Django models defined in app. I cannot find how my containers can be on the same network while having the app service in relation to the host machine. This prevents me from using the SMTP I need to use. From what I have read on this site and in the docs, it seems that it is not possible to have a service running on both network_mode=host and on a default bridge network. Here is the docker-compose.yml file. services: app: build: ./app depends_on: db: condition: service_healthy ports: - "8080:8080" volumes: ... extra_hosts: - "host.docker.internal:host-gateway" api: build: ./api depends_on: db: condition: … -
Meta Facebook Embedded Signup in Django Python
I work on a company that works with whatsapp chatbot. I created a page to make our clients signin with their facebook's business account to get permissions to send message on behalf of them. I'm implementing the embedded signup in a simple page just to get the access token. For test purposes, I created a simple backend in python to return the access token to the page. These are the codes I have: (I just replaced the ids with xxx,yyy and zzz because I think these are not needed here) Frontend <html> <head> <script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script> <script> window.fbAsyncInit = function () { // JavaScript SDK configuration and setup FB.init({ appId: "xxx", // Facebook App ID cookie: true, // enable cookies xfbml: true, // parse social plugins on this page version: "v20.0", //Graph API version }); }; // Load the JavaScript SDK asynchronously (function (d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "https://connect.facebook.net/en_US/sdk.js"; fjs.parentNode.insertBefore(js, fjs); })(document, "script", "facebook-jssdk"); // Facebook Login with JavaScript SDK function launchWhatsAppSignup() { // Launch Facebook login FB.login( function (response) { if (response.authResponse) { console.log("response", response); const code = response.authResponse.code; // Make a call to the … -

How do I deploy my containerized Nextjs and Django app to render?
I successfully containerized my Django and Nextjs apps with docker, these containers are running locally, but deploying to Render a hosting platform, I have an issue binding my service to a port, at least that's the log error message I am getting, Port scan timeout reached, no open ports detected. Bind your service to at least one port. If you don't need to receive traffic on any port, create a background worker instead.

Django-redis - Connection Closed errors after timeout set to 0
I am using Nautobot (Django-based application) that utilises Redis and Celery for asynchronous task execution. Randomly, when accessing the jobs page, I get the below error stating the Redis server connection was closed. Originally, I had Redis running in a container and later migrated to Google MemoryStore as part of the troubleshooting. Both platforms have the same issue. I've tried updating the redis configuration on both to disable timeouts: timeout 0 As well as setting the configuration in Django but the issue continues. # CACHE Configuration CACHE_RETRY = Retry(ExponentialBackoff(), 3) CACHES = { "default": { "BACKEND": "django_prometheus.cache.backends.redis.RedisCache", "LOCATION": f"{os.getenv('CACHE_BROKER_URL', 'redis://127.0.0.1:6379')}/0", "TIMEOUT": 300, "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", "PASSWORD": f"{os.getenv('CACHE_AUTH_STRING', '')}", "SOCKET_CONNECT_TIMEOUT": 10, "SOCKET_TIMEOUT": 0, "CONNECTION_POOL_KWARGS": { "ssl_cert_reqs": os.getenv('CACHE_CERT_REQUIRED', 'None'), "retry": CACHE_RETRY, "retry_on_timeout": True } }, } } CONTENT_TYPE_CACHE_TIMEOUT = int(os.getenv("CACHE_CONTENT_TYPE_TIMEOUT", "0")) REDIS_LOCK_TIMEOUT = int(os.getenv("CACHE_LOCK_TIMEOUT", "0")) CELERY_BROKER_URL = os.getenv("CACHE_BROKER_URL", "redis://127.0.0.1:6379") CELERY_TASK_SOFT_TIME_LIMIT = int(os.getenv("CACHE_TASK_SOFT_TIME_LIMIT", str(5 * 60))) CELERY_TASK_TIME_LIMIT = int(os.getenv("CACHE_TASK_TIME_LIMIT", str(10 * 60))) CELERY_BROKER_TRANSPORT_OPTIONS = { "ssl": { "ssl_cert_reqs": os.getenv('CACHE_CERT_REQUIRED', 'None') } } CELERY_RESULT_BACKEND_TRANSPORT_OPTIONS = { "ssl": { "ssl_cert_reqs": os.getenv('CACHE_CERT_REQUIRED', 'None') } } if os.getenv('CACHE_CERT_REQUIRED', 'None') == 'required': CACHES['default']['OPTIONS']['CONNECTION_POOL_KWARGS']['ssl_ca_certs'] = os.getenv('CACHE_CERT_LOCATION', '') CELERY_BROKER_TRANSPORT_OPTIONS['ssl']['ssl_ca_certs'] = os.getenv('CACHE_CERT_LOCATION', '') CELERY_RESULT_BACKEND_TRANSPORT_OPTIONS['ssl']['ssl_ca_certs'] = os.getenv('CACHE_CERT_LOCATION', '') # Construct the new URL for Celery schema, host = os.getenv("CACHE_BROKER_URL", "redis://127.0.0.1:6379").split('://') CELERY_BROKER_URL …
