Ubuntu is not serving Static files from Django project. Getting Permission issue
I have a django project deployed on Ubuntu 23.04 and using nginx and gunicorn to serve the website. Static setting is defined as follows: STATIC_DIR=os.path.join(BASE_DIR,'static') STATIC_URL = '/static/' if DEBUG: STATICFILES_DIRS = [ STATIC_DIR, ] else: STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.StaticFilesStorage' We have Debug = False in Production. Gunicorn service [Unit] Description=gunicorn daemon Requires=opinionsdeal.socket After=network.target [Service] User=panelviewpoint Group=www-data WorkingDirectory=/home/panelviewpoint/opinionsdealnew ExecStart=/home/panelviewpoint/opinionsdealnew/venv/bin/gunicorn \ --access-logfile - \ --workers 3 \ --bind unix:/run/opinionsdeal.sock \ opinions_deal.wsgi:application [Install] WantedBy=multi-user.target nginx file server { server_name opinionsdeal.com www.opinionsdeal.com; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/panelviewpoint/opinionsdealnew; } location / { include proxy_params; proxy_pass http://unix:/run/opinionsdeal.sock; } } SSL lines have been removed from nginx file in this code only but it is already there in server. I am using Django 4.2 and python 3.11 We are seeing that website HTML pages are being served but static files like js, css and images are not being served. I have deployed similar projects in past on ubuntu 20 and worked well but this time it is not working. I have given permission for static folder to all users. Please suggest if there is any solution. -
Is it possible to have a conditional statement distinguish which model a Python variable is coming from? [duplicate]
In my Django view I have 3 models and I want to do a conditional based on where a variable is coming from. I have tried... if (type(variable)) is ModelA: do this... If I do... print(type(variable)) it prints out '<class 'app.models.ModelA'>' But the conditional never kicks in. I'm not sure what I am missing. -

How to migrate database django from postgresql to mysql
Please help me, yesterday I switched providers to deploy my django website, in the old provider I used postgresql as the database, but in the new provider only supports mysql, so inevitably I have to migrate my database to mysql. For the database settings in my django project I have adjusted as follows: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'achmadir_portfolio', 'USER': '**************', 'PASSWORD': ******************', 'HOST': 'localhost', 'PORT': '3306', } } I have previously backed up my database and I want to restore it in django on a new provider.

How can I add additional metadata into the django.server logs?
What I am trying to do is as given below, The current logs for the server requests look like the following. [29/Nov/2023 02:33:50] "GET /api/health/ HTTP/1.1" 200 31 The new format I need is as following. [29/Nov/2023 02:33:50] "GET /api/health/ HTTP/1.1" 200 31 user-id:<user_id> I tried to add a logs filter. "django.server": { "()": "django.utils.log.ServerFormatter", "format": "[%(asctime)s] %(levelname)s %(module)s %(message)s user_id:%(user_id)s ", } The following is my filter. class UserIdFilter(logging.Filter): def filter(self, record): user_id = None if hasattr(record, "request"): try: user_id = record.request.user.id except Exception as exp: user_id = "anon" if not user_id: user_id = "unknown" record.user_id = user_id return True The problem is the record object above is a socket.socket object and does not have any request http payload metadata. What could I do differently to find and append the request user_id to the logs? -
Django and staticfiles
I have a problem with Django static files. Let's assume, that the Django is configured to be server at www.example.com/app. When my configuration is: STATIC_URL = "/static/" MEDIA_URL = "/media/" STATIC_ROOT = "/home/hostxxx/domains/webpage.com/DjangoApp/static" MEDIA_ROOT = "/home/hostxxx/domains/webpage.com/DjangoApp/media" Then Django looks for: https://example.com/static/styles/style.css and it doesn't exist: GET https://example.com/static/styles/style.css net::ERR_ABORTED 404 (Not Found) but the file exists here: https://example.com/app/static/styles/style.css But when I change the static url: STATIC_URL = "/app/static/" Then it looks for a good url: https://example.com/app/static/styles/style.css but now the staticfile is available here: https://example.com/app/app/static/styles/style.css Update: urls.py: from django.contrib import admin from django.urls import path from mainapp import views urlpatterns = [ path("admin/", admin.site.urls), path("", views.lists, name="lists"), # MAIN VIEW ] but tried also this as urls.py: from django.contrib import admin from django.urls import path from django.contrib.staticfiles.urls import staticfiles_urlpatterns from mainapp import views urlpatterns = [ path("admin/", admin.site.urls), path("", views.lists, name="lists"), ] urlpatterns += staticfiles_urlpatterns() and base.html: {% load static %} <!DOCTYPE html> <html lang="en"> <head> <title>AAA</title> <link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" /> <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.11.5/css/jquery.dataTables.min.css" /> <link rel="stylesheet" href="{% static 'styles/style.css' %}"> # HERE ...

Django Migration Error with PostGIS: 'double free or corruption (out) Aborted (core dumped)
I am developing a web application using Django and encountering a critical issue during database migration with PostGIS. While migrations work seamlessly with the SpatiaLite engine, switching to the PostGIS engine leads to a crash. The error message I receive is: "double free or corruption (out) Aborted (core dumped)". This issue arises specifically when I attempt to make migrations with the PostGIS engine. My Django project settings for the database are as follows: DATABASES = { 'default': { 'ENGINE': 'django.contrib.gis.db.backends.postgis', 'NAME': 'geodesia_interoperable', 'USER': 'depiction', 'PASSWORD': '************', 'HOST': 'localhost', 'PORT': '5432', } } I have verified that PostgreSQL and PostGIS are correctly installed and configured, and the database credentials are accurate. The application runs as expected with SpatiaLite but fails when switched to PostGIS. Has anyone encountered a similar issue, or does anyone have insights into what might be causing this error with PostGIS in Django? Any suggestions for troubleshooting or resolving this problem would be greatly appreciated. -
React: 'map' function
I'm fetching a list of objects. Using map function should display a list but there wasn't. I checked if it was saved to 'useState' via console.log(posts), and yes there was a list of objects. My only problem is I cant display it to the browser. Also, I already attached the necessary scripts for 'react', 'reactDOM', and 'babel'. {% extends "network/layout.html" %} {% block body %} <div id="index"></div> <script type="text/babel"> const AllPosts = () => { const [posts, setPosts] = React.useState([]); React.useEffect(() => { fetch("/allposts") .then((response) => response.json()) .then((data) => { setPosts(data.posts); }) .catch((error) => { console.error(error); }); }, []); return ( <ul> {posts && posts.map((post, index) => { <li key={index}>{`Try ${index}`}</li>; })} </ul> ); }; const Index = () => { return <AllPosts />; }; const container = document.getElementById("index"); const root = ReactDOM.createRoot(container); root.render(<Index />); </script> {% endblock %} I wanted to return each object on the list in an li tag, however, there was no data when I inspected it on the browser. -

customize django admin panel login view
I Want to do a little job when an admin wants to log into the admin panel. and that's it: I have a gateway service and I want from that gateway to handle authenticating of my users and just give me a token and then I handle them with the help of that token. now I'm confused how can I add my preferred logic alongside with all the default logic of handling authentication and logging admins into admin panel of django. I tried to override the default method, or even copy & paste that logic all by hand :/ thanks for any help or recom.. :) -
Django floatformat: no unnecessary zeros
Django's floatformat filter has a few options for formatting decimals. However, none of them work for what I consider the "standard" way to represent decimals in non-programming fields, like math or science. Specifically, I'd like decimals to be displayed with "as many decimal places as needed", up to a defined limit. Here are some examples with a limit of 3: The decimal What I want floatformat floatformat:3 floatformat:"-3" 15.000000 15 15 ✅ 15.000 ❌ 15 ✅ 15.666667 15.667 15.7 ❌ 15.667 ✅ 15.667 ✅ 15.550000 15.55 15.6 ❌ 15.550 ❌ 15.550 ❌ 15.500000 15.5 15.5 ✅ 15.500 ❌ 15.500 ❌ Tests passed: 2/4 1/4 2/4 The closest filter for my goal is probably {{ thing | floatformat:"-3" }}, and that's what I'm using right now. All I would like is to remove the "trailing zeros" from this filter's output. Thanks a lot! -

Django 5.0 how to serialize class-based sessions without django.contrib.sessions.serializers.PickleSerializer
I saw Django 5.0 was released today and I am messing around with it, but I see that the PickleSerializer was removed. What is the preferred way of serializing class-based session data now? I see it states use JSON but that breaks my code as I store actual objects in the session for easy reference in some instances (so I get messages that Model object is not JSON serializable), is there an easier, yet still secure way to pickle sessions in Django? -- I store objects inside of sessions occasionally and it works really well for db related access and things of the sort as I don't need to recall the DB. In my settings I was using: SESSION_SERIALIZER = 'django.contrib.sessions.serializers.PickleSerializer' You can see it was depreciated in 4.2 and removed in 5.0 here: https://github.com/django/django/blob/stable/4.2.x/django/contrib/sessions/serializers.py As a note, I am trying to figure out if I should alter my code to not store objects via pickle in my session, or if it really matters given I validate and grab data based on my defined objects, not specifically user-defined input -

Trouble Parsing JSON Data in Python [closed]
I'm currently working on a Python project where I'm receiving JSON data from an API, but I'm facing difficulties parsing it correctly. The JSON data looks like this: "name": "John Doe", "age": 30, "email": "johndoe@example.com", "address": { "street": "123 Main St", "city": "Anytown", "zip": "12345', "skills": ["Python", "JavaScript", "SQL"] I'm trying to extract specific information from this JSON object, such as the person's name, age, and skills. However, I'm not sure how to correctly parse this JSON in Python to access this data. Could someone provide an example of how I can extract this information from the JSON object and store it into variables or access it directly? -
"MultipleObjectsReturned or ObjectDoesNotExist error when accessing 'google' provider in Django-allauth"
I'm encountering an issue when trying to access the 'google' provider in Django-allauth. I'm getting either a MultipleObjectsReturned or ObjectDoesNotExist exception. I have followed the documentation and tried various troubleshooting steps, but the problem persists. Here is the code snippet from my views.py file: from allauth.socialaccount.models import SocialApp from django.core.exceptions import MultipleObjectsReturned, ObjectDoesNotExist def home(request): try: google_provider = SocialApp.objects.get(provider='google') except MultipleObjectsReturned: print("Multiple 'google' providers found:") for provider in SocialApp.objects.filter(provider='google'): print(provider.client_id) raise except ObjectDoesNotExist: print("No 'google' provider found.") raise return render(request, 'home.html', {'google_provider': google_provider}) I have also imported the necessary modules SocialApp and MultipleObjectsReturned/ObjectDoesNotExist from allauth.socialaccount.models and django.core.exceptions respectively. I have checked my database, and there is only one entry for the 'google' provider in the SocialApp table. The client_id is correctly set for this provider. Despite taking these steps, I am still encountering the mentioned errors. I have made sure to restart my Django server after any code or database changes. -
Django : can't return redirect in a sub function exception. The first function continues

Did I miss something in my redirect or exception handling comprehension ? Because even if I set a redirect in all a functions' Exceptions, the behavior doesn't change. -
Issue with Django Migration - "Table already exists

Django capture traces of all invoked function Open Telemetry
I am a newbie to Open Telemetry and trying to see how traces are captured for a Django app. I am assuming that OTel should be able to provide traces of all invoked functions for a particular Django Request. E.g.I have a very basic Django app with a views.py as def log_console(): print("Print in terminal") def show_date(): now = datetime.now() log_console() return HTMLResponse() The url is configured to serve show_date My expectation js that when I configure manage.py with DjangoInstrumentor().instrument() In the console I should be able to see reference to the function log_console as it is invoked when serving the show_date But cant see any reference to log_console, not sure if this is a valid use case for Tracing in Open Telemetry -
Django's Very slow initial execution of select query on remote Oracle 11 database when table contain big blobs
I actually understand what is causing the problem but can't figure out a solution that works with Django. suppose you are trying to read 10,000 records from oracle database over network, normally that would result in 10,000 network connections being open and closed which causes bad performance. Oracle's answer to that is to send say 1000 records at once per connection, that significantly improve the speed. However in my case, each row contains blobs that are 1-2MBs, so trying to prefetch 1000 records means nothing happens until I've downloaded (and kept in memory) 1GB-2GB worth of data. oracle's sqlplus provides option to control that, either using the fast parameter or issuing set rowprefetch 10 but I can't find solution that works with Django. I only want to prefetch 10 records or so
