`python manage.py qcluster` doesn't work on Windows 10, but the same project works on Linux
The problem is that I fetched a new part of the project related to qcluster from my colleague. I merged it with my project, but when I tried to use it with PS C:\Users\b2b\Desktop\tech\squirll> python manage.py qcluster I received this error: PS C:\Users\b2b\Desktop\tech\squirll> python manage.py qcluster 19:32:12 [Q] INFO Q Cluster pip-september-tennessee-papa starting.

Where is the parameter 'request' used in view.py in django
A newbie in Django web development. I've got a tiny but puzzling question about request / response in views.py. I self-learn Django online and here comes the http request / response section. The code is as follows: #from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("<h1>123</h1>") I understand that the index page is requested and django creates a response which shows 123 in the index page. My questions are: with the request as the parameter of the function, isn't it used in the body of the function, just like def math(x): return x+1? Also, why does render become redundant in this trunk of code, where it should be used to produce output? Thanks for answering. -
Using django select_for_update for not updating but creating new records
I am using Django==2.2 and trying to create some new records for an object in django only if an upper limit is not reached. I was checking with unused_count = Account.objects.filter(field1__isnull=True, field2__isnull=True).count() vacancies = UPPER_LIMIT - unused_count if vacancies > 0: *create (vacancies) new accounts here* however we faced a case where this is not being respected and double the max limit accounts got created, and most probably seems like a concurrency issue. Just wanted to confirm that using unused_count = Account.objects.select_for_update().filter(field1__isnull=True, field2__isnull=True).count() will suffice and prevent this issue or not? The whole method is wrapped in @transaction.atomic -

This is what i want! I have a view and i want to send the API JWT Token along with request i want to verify if the token is valid or not if it is Valid it gives the responce Response({"gpcars": gpSerial.data, "featuredCars": featSerial.data, "recentcars": RecentSerial.data}, status=status.HTTP_200_OK) and if its not valid so the user is unauthenticated then this should be the responce Response({"gpcars": gpSerial.data, "featuredCars": featSerial.data, "recentcars": RecentSerial.data}, status=status.HTTP_401_UNAUTHENTICATED) Basically i want to determine if the user is logged in or not along with the request.

Django consumer frequently get disconnected and reconnected on different pods on K8S
big brothers! I deployed my Django app on K8S pods. I implemented websocket server with websocket consumer using Django channels package. And the problem is, I found K8S would frequently close and reconnect websocket connection, that's to say K8S would frequently new consumer objects on the same websocket connection URL on different pods. I have cached data inside consumer object, and this situation really bothers. How can I keep websocket connection in K8S? -

Adding a Threaded Comment functionality in my Django blog using FETCH API
Please I am stuck on a problem I've been trying to solve by myself for up to a month now. I am at my wit's end. So I have a Django blog and I am trying to implement a threaded comment functionality using FETCH API to avoid a page refresh each time a comment is submitted. Also, I intend to limit the number of comments shown first to just 10 with a "load more comments" button at the bottom that when clicked would reveal the next 10 comments, and so on until there is no more comment to be shown at which point the "load more comments" button disappears. You see, I successfully implemented this feature with FETCH API for only single parent comments. But I am trying to take my blog further by adding a threaded comment, or rather, to make it possible for parent comments to have child comments. However, I can't seem to successfully implement the above functionalities asynchronously. Only after reloading the page do the parent comments and child comments show on the page, but I want the comments to show immediately after hitting the comment submit button. I believe the problem is with my Javascript … -
How to make text remain on page even after user exits and opens again?
Using js,it is possible to make text remain on screen when user submits the text, but I want that it remains even after user exits or lets say opens the website on a different device. I think databases would be involved. Can we use Django for this purpose? I am trying to make a website like a common notepad type thing. Anyone who opens the site can add text and leave and it stays there until he himself or any other person removes the number. How should I proceed with this idea? -

Why do we need to install pytz package when we want to use Django with MondoDB?
After many research, i found that to use Django with MongoDB, we have to install pytz and downgrade pymonngo to 3.12.3, because the new version of pymongo (4.0 from 29.11.2021) is not supported by Djongo 1.3.6. But what's the interest of pytz ? When i try to use Django with MongoDB without installing pytz, it doesn't work. -
How do I fix a database configuration error when securing Django Admin with two factor authentication using custom user model and database?
I am trying to add two factor authentication to the Django Admin Site as an extra layer of security using django-otp (version 1.2.2) and qrcode (version 7.4.2). Both have been installed as part of django-two-factor-auth (version 1.15.4). Furthermore, I have set up a custom user model in a custom Postgresql database. For the setup of the custom user model and database, I followed the tutorial Django Real Estate App Using Multiple Users & Databases by Brian Brkic (especially parts 1, 2, 3, and 10). For the implementation of the two factor authentication, I have started with the tutorial Towards Django Two Factor Authentication Integration by Very Academy, but continued with Django Two Factor Authentication Example because I thought I could avoid all the extra forms. The migration to the custom database python manage.py migrate --database=users worked well and the Admin Site at localhost:8000/admin is presented properly, including the field for the OTP code. However, when I fill in the username, password and OTP code in the login form and hit send, I get the error ImproperlyConfigured at /admin/login/ settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details. I came across this type of error … -

Getting custom User details from access token in API(DJANGO)
