Django-allauth change password not working
first time poster be gentle. I have created a project using allauth with the documentation including adding bootstrap elements. My login/logout/sign up pages all work but when I do change or forgotten password I get a confirmation saying password is changed successfully but only the old password still works. I even span up a fresh project with nothing else added such as custom user etc and this still happens and I can't figure out why it doesn't work out if the box. Any ideas? -

Generate html to pdf using xhtml2pdf in django project
I have an HTML page containing multiple tables. When converting it to a PDF using xhtml2pdf, it works fine if only a few tables are expanded. However, if I expand more tables, I run into a size limitation where the PDF turns out blank if the content exceeds a certain size(30Mb).

Accessing MEDIA_URL & trailing slash redirect
In order to access {{ MEDIA_URL }} from templates, I added + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) to my urlpatterns. Recently I noticed that this breaks the default APPEND_SLASH functionality in Django. I.e. I get a 404 when the trailing is missing, unless I remove + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) from urlpatterns, in which case it correctly redirects to the URL with the trailing slash. I think I'm missing something fundamental, because it seems to me that accessing MEDIA_URL from templates is a basic requirement to display media correctly, without breaking other basic functions in Django. -
Custom GraphQL String Field Parameter
I'm required to sanitize all my inputs coming in via the GraphQL endpoint and remove potential malicious stuff (No the Django build-in mechanism are not enough, it shall be actively removed). As I do not want to add the sanitization for every mutation manually, I thought about creating a custom graphene.String() class called clean_string.String() including nh3.clean() for the sanitization so I must only exchange singe lines: import graphene import nh3 from graphql import StringValueNode, Undefined class String(graphene.String): @classmethod def parse_value(cls, value): if isinstance(value, str): cleaned_value = nh3.clean(value) else: cleaned_value = value return super(String, cls).parse_value(cleaned_value) @staticmethod def parse_literal(ast, _variables=None): if isinstance(ast, StringValueNode): return nh3.clean(ast.value) return Undefined In my schema.py I have then import clean_string class CreateUser(graphene.Mutation): user = graphene.Field(UserType) class Arguments: email = clean_string.String(required=True) password = clean_string.String(required=True) @staticmethod def mutate(_, info, email, password) # sanitized email & password But this does not get called at all. When I have inputs like <img>password</img> and do the sanitation manually the result will be <img>password but with my custom class nothing happens. Does anyone have a clue how to resolve this? Thanks in advance! -

Switching from WSGI to ASGI (Gunicorn + Uvicorn) in Django Production – Site Not Loading
I recently built a Django application using Django Channels for WebSocket support. My asgi.py is set up for handling both HTTP and WebSocket connections, and everything works perfectly in development using Daphne and Uvicorn. In Productin initially, my app was running on Gunicorn (WSGI), but since I need WebSocket support, I switched to Uvicorn (ASGI). To achieve this, I modified my gunicorn.service file to use UvicornWorker instead of the default WSGI worker. I encountered the error: Django can only handle ASGI/HTTP connections, not lifespan. To fix this, I created a custom worker class based on a solution from older Stack Overflow answers: from uvicorn.workers import UvicornWorker class MyUvicornWorker(UvicornWorker): CONFIG_KWARGS = {"lifespan": "off"} Then, I updated my gunicorn.service file: [Unit] Description=gunicorn daemon Requires=gunicorn.socket After=network.target [Service] User=django Group=www-data WorkingDirectory=/home/django/my_project ExecStart=/home/django/my_project/venv/bin/gunicorn \ --limit-request-line 8190 \ --access-logfile /var/log/gunicorn/access.log \ --error-logfile /var/log/gunicorn/error.log \ -k project.uvicorn_worker.MyUvicornWorker \ --workers 3 \ --env DJANGO_SETTINGS_MODULE=project.settings.base \ --bind unix:/run/gunicorn.sock \ --log-level=debug \ project.asgi:application ExecReload=/bin/kill -HUP $MAINPID [Install] WantedBy=multi-user.target After restarting gunicorn.service, everything appears to be running fine, gunicorn.service and nginx.service are active ping mysite.com is working No errors in /var/log/gunicorn/error.log -
Django: Migrations not detecting changes after manually deleting migration files in production app
What happened: I had an app called app with migrations up to 0012. I mistakenly deleted migration files, including 0001_initial.py. Now, when I run python manage.py makemigrations app, no new migration files are detected, even though I have made changes to the models. This issue is persisting even in a newly created app called comments, where no migration files are being detected either, despite having added new fields to the models. What I’ve tried: I’ve ensured that the app is listed in INSTALLED_APPS. I’ve run python manage.py makemigrations app to generate migration files, but no changes are detected. I can’t drop the database as it is a production environment, and I need to preserve existing posts and data. What I need help with: I need to figure out how to properly reset or re-sync the migrations without losing any production data. For now i have empty migrations folder with init.py innit that doesnt create any migration file. Specifically, how do I: Recreate missing migrations after deleting files manually (i.e., to match the state of the database, which still has migrations applied up to 0012). Ensure that any new apps or changes to models are correctly detected and have corresponding migration … -
Encrypt and decrypt the data that can be seens in the Swagger of the Django when making any Rest API
I am making a django project and using DRF to make the API's also using the Swagger UI to make it interactive for the backend testing Image of the Swagger Request which can be seen So in this image i want to make the "-d" to be encrypted and also in the frontend when i want to encrypt the data when you go see it in the networks also decrypt the data when API is using making the CRUD operations with the database. I am using the serializers here. How can i implement the encryption and make changes in the serializers or the curl "-d" option so that i can only see the encrypted Data in swagger. Shall i make a middleware to encrypt the data? How i can also encrypt the data whenever my response is being given by the API. So that on frontend when using inspect it is encrypted Data. Thanks in Advance and for your suggestion to make my project better and secure!! -
Can't read "csrftoken" from cookies (Django)
I am working on a Django backend. The backend is deployed on Render, and I am testing email validation logic by sending OTP but for that i need to send "csrftoken" for the POST request. At first the cookie was not getting set in cookies in firefox (but was getting set it chrome), since it was asking for the cookie to have partitioned attribute set, since django does not yet support it, i had to include a custom middleware to do it.

Why is request.user not being populated in Django when using custom JWT middleware?

Django Scraper Matching Issue: match_maker Only Returns 4 Members Instead of 150
Question: I'm working on a Django project that uses Scrapy to scrape member profiles from a website. The scraped data is processed by a method called match_maker. However, I'm encountering an issue where match_maker only returns 4 members, despite having 150 members in the database (excluding 3 staff members). Details: Database: Contains 153 members; 3 are staff members, leaving 150 regular members. Profile Types: Each member has a profile_type of either 'Man', 'Woman', 'Trans', or 'Couple'. Issue: In the match_maker method, there's a loop that processes rooms and assigns them to members. A set named used_rooms is used to track assigned rooms to ensure each room is only assigned once. The relevant code snippet is: if room["username"] in used_rooms: continue When this condition is active, only 4 members are returned. If I comment out this check, the method processes all 150 members, but the number of available rooms exceeds one million, which is incorrect. Objective: I need each room to be assigned to only one member, ensuring no more than one member owns a particular room. I'm looking for guidance on how to resolve this issue so that match_maker correctly processes all 150 members without assigning multiple members to the … -
Django Streaming Video / Audio - RangedFileResponse
Folks, For ages I've been using RangedFileResponse to enable streaming (particularly with Safari), but to allow ranged streaming with Django. (Please note, it's been forked quite heavily, the one I've been using is from https://github.com/devmonkey22/django-ranged-fileresponse. Now, I've been always wondering if there was a more up-to-date way to do this, since there hasn't seemed to be a better answer? I just recently started to use django-extensions more fully, and bumped into the Werkzeug extensions when I enabled SSL for the Dev environment. But I also found that Werkzeug can help with the Ranged file response. This is what I came up with, and it seems to be faster than using the django-ranged-fileresponse. Sometimes significantly faster. from werkzeug.http import parse_range_header from django.http import FileResponse, HttpResponseNotAllowed, HttpResponseBadRequest def stream_video(request, fqpn, content_type="video/mp4"): file_size = os.path.getsize(fqpn) if request.method != 'GET': return HttpResponseNotAllowed(['GET']) if request.is_secure(): range_header = request.META.get('HTTPS_RANGE') else: range_header = request.META.get('HTTP_RANGE') ranges = parse_range_header(range_header) if not ranges: return FileResponse(open(fqpn, 'rb')) # For simplicity, handle only single range requests start, end = ranges[0] with open(fqpn, 'rb') as file_to_send: file_to_send.seek(start) data = file_to_send.read(end - start + 1) response = FileResponse(data, content_type='application/octet-stream') response['Content-Length'] = len(data) response['Content-Range'] = f'bytes {start}-{end}/{file_size}' response['Accept-Ranges'] = 'bytes' response.status_code = 206 # Partial … -
Why transition-duration along with transform scale could not be set via js/css? (But could be set via DevTools)
The problem is setting transition-duration along with transform scaling results in transformation with zero duration (although style shows up in DevTools as expected) if being set through css, js or html style. But results correctly if being set manually through browser DevTools (changing aforesaid style in DevTools). The MRE is just: <div style="transform: scale(~times~); transition-duration: ~time~"> sandy </div> Working through Django latest version. In the meantime, opacity trasition-duration works as expected, so the trouble is about scaling. Checked the issue in firefox, edge and chrome Though the MRE works as expected in fiddle -

How to store images
I store various image files in my media file in the Django framework and I use MongoDB to store my data, but as far as I understand, storing photos directly in MongoDB is not a preferred method. What path should I follow at this point to get a more efficient result? I thought about using tools like AWS S3, but I'm not sure if this is the right way, and I'm inexperienced in data management. I would appreciate it if you could briefly explain how to do it.
