How can a Django app on a Raspberry Pi safely trigger an upgrade of itself using apt and systemd?
I'm distributing a Django/Python web application as a Debian package on a Raspberry Pi. I’d like to implement an "Upgrade" button in the web UI that triggers a sudo apt update && sudo apt -y install my_app to upgrade the application package. The challenge is that the app is trying to replace itself while it's still running — the very code initiating the upgrade is part of what will be upgraded. What I've tried: The Upgrade button sends a POST to the Django backend. The backend uses python subprocess to start a oneshot systemd unit (gui-package-update.service) that runs the upgrade commands (via sudo). The Django app itself is started on boot using another systemd service and runs as a non-root user. I've configured sudoers to allow the Django user to run sudo systemctl start gui-package-update.service without a password. A second POST api call is used to monitor the state of the upgrade, those states being: running - the server is up and running upgrading - the server has received the POST command to start an upgrade 404/500 - the server is currently rebooting The 404/500 errors are caught in the JS front end and interpreted to mean that the server … -
How to solve "X-Csrftoken HTTP header has incorrect length" error from React Native with Django API?
The program should make a POST Request to logout a React Native client (Android with Expo Go), ending it's session. The program stores both user's session id and CSRF token from Django response after login, with React Native asyncStorage. And when trying to make the logout request by sending both session id and CSRF token as headers, the program shows the title error. Logout Request const postRequestLogout = async () => { try { //getting both sessionid and csrftoken from asycStorage const sessionid_value = await AsyncStorage.getItem('sessionid') const csrftoken_value = await AsyncStorage.getItem('csrftoken') console.log("Session: ",sessionid_value) console.log("Csrf: ",csrftoken_value) //Here these values are passed to headers const requestOptions = {method:'POST',headers: {'Content-Type': 'application/json','Authorization':sessionid_value,'X-CSRFTOKEN':csrftoken_value}} await fetch( 'http://myIP/user_account/api_logout_user_account/', requestOptions) .then(response => { response.json() .then(data => { Alert.alert("Sucesss"); console.log(data) }); }) } catch(e) { console.log(e) } } Login request const PostRequestLogin = () => { const email = "myemail" const password = "mypass" setSessionId = async (value) => { try { await AsyncStorage.setItem('sessionid', JSON.stringify(value)) } catch(e) { console.log(e) } } setCsrfToken = async (value) => { try { await AsyncStorage.setItem('csrftoken', JSON.stringify(value)) } catch(e) { console.log(e) } } const requestOptions = { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ email:email,password:password}) }; const postRequestLogin = async () => … -
Verifying user location for an action in a site [closed]
I am building an Employee Management system using django and angular (that's what I am most proficient with). Now pretty much every thing is implemented except the verification for check in that proves users are actually in the office. I have two options, checking if the user is connected to the company's wi-fi(a starlink router) and checking the user's geographical location. We eliminated the option for a QR code not to need an extra device(convenience). The option of using the company network is kind of off the table because you can not get any unique information about the router from the browser(non that i know of). But for the geo location, I have used the geoip2 on django and it was not good enough. I have also used the HTML5 geolocaion from the browser but it is only accurate on mobile devices. Is there any better geoapi(preferably free. I am an just an intern), or any other way I can achieve this? I am open to any feasible ideas -
CSS Static Files Not Updating After Successful Deployment
I'm experiencing an issue with my Django application deployed on Railway where CSS changes are not being reflected on the live site, even after successful deployments and clearing browser caches. Project Setup: Framework: Django Static Files Serving: Whitenoise (whitenoise.middleware.WhiteNoiseMiddleware and whitenoise.storage.CompressedManifestStaticFilesStorage are configured) Repository Structure: Standard Django layout with manage.py, Procfile, requirements.txt in the root. settings.py/wsgi.py are in comparaplan/comparaplan/. Static source files are intended to be in comparaplan/static/. Railway Root Directory Setting: / (Repository Root) Deployment Process & What Works: Builds complete successfully. The Pre-deploy Command is set to: python manage.py migrate && python manage.py collectstatic --noinput --clear The deployment logs clearly show both migrate and collectstatic running successfully during the pre-deploy phase. collectstatic reports copying files (e.g., XXX static files copied to '/app/staticfiles'). The Start Command is set to: gunicorn comparaplan.comparaplan.wsgi --bind 0.0.0.0:$PORT --log-file - (or it's correctly defined in the Procfile and the start command field is empty). The runtime logs show Gunicorn starting successfully and listening on the correct port. The application loads without 5xx errors. The Problem: Despite the above, CSS changes made to files (specifically tested with comparaplan/static/styles/global.css) are not visible on the deployed site. Troubleshooting Steps Taken: Confirmed CSS changes were committed and pushed … -
.show() not displaying <div> on click, despite confirmed event trigger and DOM presence

Django Autocomplete reversed ForeignKey field

I try replace FilteredSelectMultiple widget to AutocompleteSelectMultiple widget, but AutocompleteSelectMultiple do not work without many-to-many field in Group model. I try override AutocompleteMixin class to create custom AutocompleteSelectMultiple widget, but I didn’t succeed: the AutocompleteSelectMultiple widget still required a many-to-many field in Group model.

New media files not found at django website hosted on azure
A Django website works correctly both locally and on PROD. PROD is azure app service. Since it's deployed to a temporary storage (container, I presume), which is overriden with each deploy, I don't want media files to be overriden every time. So I've moved them to the media folder outside of deployed website folder, but it's inside site/wwwroot, so that I can use it via ftp as well. And those files that where already in the folder site/wwwroot/media, are working fine. But new ones return 404 error on attempt to read them. I've checked and those new files exist and they are exactly in the same folder as old images. I've double checked and tried the same url from the old image, copy-pasted new image file name from ftp on PROD and pasted it into the browser, but it still gives me 404 error. So for some weird reason website can access file system to read and write, but on attempt to open in browser any image file that was uploded after deploy, it fails. It feels like it's just remembering a list of files there and doesn't even check if actual file exists if it wasn't there on deploy. … -
Authenticating to a django backend from a vite frontend on a different subdomain hosted on self-hosted coolify instance
Hello I am trying to deploy two applications to a self hosted Coolify instance and I am unable to authenticate from my frontend. They are on different subdomains as you can see from the example below: Vite frontend (format): https://project.mydomain.com/#/login Django backend (format): https://api.mydomain.mydomain.com/ (Also one thing to mention is that I am using caddy as my reverse proxy in Coolify) When I try to login from the frontend I get the following error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.mydomain.mydomain.com/api/api-token-auth/. (Reason: header ‘access-control-allow-origin’ is not allowed according to header ‘Access-Control-Allow-Headers’ from CORS preflight response) I have been reading about CORS for days and still cannot figure it out.

Djoser | password reset nightmare
I’m using Djoser + Django REST Framework for authentication and I’m getting a little frustrated about the password‑reset flow (JUST A LITTLE 🥲). My password‑reset emails generates links like: (http://localhost:8000/auth/users/reset_password_confirm/uid/token/) The problem is that this endpoint expects a POST with the user’s new password, but clicking the link issues a GET, so the request fails immediately. Most of the solutions I’ve found feel hacky, because they require either: Overriding the Djoser view to handle a GET (redirecting to my frontend) and then handling a POST to the same URL to set the new password Modifying Djoser’s email templates (which just feels bad to me) Does anyone know a cleaner way to work around this? Any alternative patterns, suggestions, or insights would be hugely appreciated! -
Implementing efficient data history/versioning in django + postgres
I'm trying to track changes to persisted data in a django + postgresql stack by saving operations on rows and 'replaying' events from the beginning (or a smaller number of snapshots) to restore an arbitrary past version. After some research I'm pretty sure I want this to be done via postgresql triggers and that one should store the pg_current_xact_id() value to get a logical order of transactions (is the latter correct?). Looking around for libraries that do this, django-pghistory seems perfect for this, but upon inspection of the data structures this library only stores UUIDs and timestamps. The former is not ordered and the latter seems prone to race conditions since two parallel transactions can start at the same time (within clock precision). Am I missing something here? Additionally, I find it essential for performance to save a full snapshot of an object/table after a large number of changes so that the execution time to jump to a specific version does not deteriorate with many changes. However, none of the available solutions I found seem to be doing this. Am I missing something here? Is the performance negligible for most applications? Do people start rolling their own version when it … -
How to prevent user from modifying data through Django DRF
My API endpoints are exposed to the browser via Django DRF which I'm aware is normal. However, the primary issue with this is that someone can perform any operation my API can perform without going through my application. I have validation for my endpoints but the user could delete payment records, for example, or POST invalid data, and other similar operations. I am using JWT auth but if the user is already logged in my application in the same browser they can see it. Is there any way to prevent this? -

Django downloads binary file from FastAPI (MinIO presigned URL), but the file is corrupted and downloaded with wrong name
I'm using Django (frontend) and FastAPI (backend) with MinIO as file storage. My setup: FastAPI generates a presigned MinIO download_url for the file. Django fetches metadata via FastAPI, then downloads the file using requests.get(download_url, stream=True) and returns it with StreamingHttpResponse. Here is my Django view for downloading the file: from django.http import StreamingHttpResponse, Http404 from django.utils.encoding import smart_str from urllib.parse import quote import requests def download_file(request, file_id): print(f'file_id = {file_id}') try: url = f"http://89.150.34.163:8000/api/v1/student/download/{file_id}" response = requests.get(url) if response.status_code != 200: raise Http404("Файл не найден") json_data = response.json() download_url = json_data.get("download_url") original_filename = json_data.get("original_filename", f"file_{file_id}") print(f'filename: {original_filename}') if not download_url: raise Http404("Ссылка на скачивание отсутствует") file_response = requests.get(download_url, stream=True) if file_response.status_code != 200: raise Http404("Ошибка при скачивании файла") filename_ascii = smart_str(original_filename) filename_utf8 = quote(original_filename) response = StreamingHttpResponse( streaming_content=file_response.iter_content(chunk_size=8192), content_type=file_response.headers.get("Content-Type", "application/octet-stream") ) response['Content-Disposition'] = ( f'attachment; filename="{filename_ascii}"; ' f"filename*=UTF-8''{filename_utf8}" ) return response except Exception as e: print(f"Ошибка при скачивании: {e}") raise Http404("Ошибка при скачивании файла") When I download the file via browser (pasting the download_url directly), it works perfectly — correct filename and contents.

I changed my Django App name and not DB names do not match
I am using Django and I wanted to change an app name from "project" to "projects" to make it cleaner and match the other models. So i did the usual Django stuff. Change config name, changed config Url, change App folder name. Even changed the apps.py and the urls to app_name = 'projects' The migrations went ok. Issue is the database is still showing everything as project_*** in the database. So now I am getting errors like these: ** error relation "projects_overview" does not exist LINE 1: SELECT "projects_overview"."a_id" FROM "projects_overview" It wants the new "S". how can I get the database to show the correct prefix of projects_ and not the old project_? will I have to use Postgres commands to change all the tables manually or did I miss some Django command. DBs are not my thing so very greatful for anyones kind help. Thank you. -

Django Undo Feature - Creating a single list of actions to undo changes in multiple models
I'm starting to add an "undo" feature to a Django Web App, and I'm not sure the best approach. I looked at some of the revisioning packages like django-simple-history but ran into issues: not all of them handle bulk_update and similar methods, and since the modals are all linked and an update here triggers a bulk-update there and delete loop there, the simplest approach seems to be undo-ing one step at a time. The packages I've found want to handle each model separately without an app-wide chronological list, so to properly roll back a change I need to query every history record and sort them by date, then roll back everything until I hit the desired position. This seems to be problematic, I feel like I'll run into issues with things being out of order, or simple speed issues while pulling the last 100 records for every historical object and merging/sorting them together into a chronological list. I'm leaning towards - making an audit log of every change app-wide, marking items for deletion instead of deleting them, etc., and pretty much rolling my own system. Am I falling victim to "not invented here"? Is there a simple process I'm missing? … -
Django JSONFIeld's widget for data input in format: forms.Select (key) - forms.TextInput (value)
I have a hard times to implement "user friendly" JSON input within a form. I have some Item model which contains attributes = JSONFIeld(). class ItemType(models.Model): title = models.CharField() class Item(models.Model): title = models.CharField() item_type = models.ForeignKey(ItemType) attributes = models.JSONField() To keep particular "schema" within a single ItemType I've added models: class ItemAttribute(models.Model): title = models.CharField(max_length=100, unique=True) class ItemAttributeSpec(models.Model): item_type = models.ForeignKey(ItemType) attribute = models.ForeignKey(ItemAttribute) required = models.BooleanField(default=False) choices = models.JSONField(default=list) So a goal for implementation: Provide a set of attributes' key/value pairs where key of JSON field will be forms.Select() or just label (doesn't matter much as I can manage implementation of this feature) and value is an input. So every single Item form instance would has all type-related attributes for input. Generally some kind of formset within a single form instance. Something like this: -

Django ImportExport: How to remove inline <ins> tag background color in import preview with Jazzmin admin?
I'm using Django with the Jazzmin admin theme and the django-import-export package to bulk import model data through the admin panel. When importing, the import preview page highlights newly added rows or changed fields using an inline tag like this: <ins style="background:#e6ffe6;">Paris</ins> This creates an unwanted green/purple background that conflicts with my custom admin styling. **What I've tried so far:** Created custom_admin.css at: project/static/admin/css/custom_admin.css Linked it correctly in admin.py: class Media: css = { "all": ("admin/css/custom_admin.css",) } js = ("admin/js/custom_tabs.js",) Added the following aggressive CSS rule: .import-preview td ins, tr.row-new td ins, .import-preview td > ins { all: unset !important; background-color: #fff !important; color: #000 !important; display: block !important; text-decoration: none !important; width: 100% !important; } Ran collectstatic and did a full cache refresh (Ctrl+Shift+R) Verified that custom_admin.css is loaded correctly via DevTools - Still, the inline style style="background:#e6ffe6" overrides everything. What I also attempted: Overriding the template import_preview.html (placed at project/templates/import_export/import_preview.html) with a custom version that removes the <ins> tag completely and wraps cells in <div> instead. But the default template still seems to load or my override isn’t being used. My setup: Django 5.1.1. django-import-export 3.3.5. Jazzmin admin theme. Static and template settings are configured properly. Question: How … -
