IIS django static files not showinvg
i try to deploy my Django app on IIS for work but is not serving my static files. i watched this tutorial: https://www.youtube.com/watch?v=APCQ15YqqQ0.

Design DB to calculate prize based on distance of cities
I am working on a side project to calculate the prize of the service based on the city distances. In my prize table I have values like below: CATEGORY DISTANCE VALUE Category A < 100 km 10EUR Category A From 100 km to 300 km 50 EUR Category A > 300 km 100 EUR My idea is to prepare a DB structure like below: CATEGORY DISTANCE_FROM DISTANCE_TO VALUE Category A 0 100 10 Category A 100 300 50 Category A 300 x 100 Is this the right approach? I am also wondering how to later get the correct value if for example distance is 150 km? The project will be build in Django, any help appreciated. -
Django login_required doesn't work with multiple gunicorn workers
So I have a project which contains multiple micro-services, the entry point is the Django micro-service(with user login & authentication). All other Apis are wrapped with the @login_required decorator by Django. I've deployed it using ngnix, gunicorn inside a kubernetes pod. Everything works fine with 1 worker(sync) but I obviously want multiple workers, so when I increase my number of workers and threads(gthread), it doesn't let me login redirects to login/?next=/login/5/. After spending some time, I figured out the following: Since the default value of keepalive of a worker is 2s, the worker closes connection and a new worker is assigned & since they don't share common memory,my session cookie isn't carried forward. I tried increasing the keepalive time to 10s , now it lets me login but if someone tried to login when the worker is about to expire(around 10s), same, doesn't login & redirects to login/?next=/login/5/. Another direction I found was about fixing the secret key as in this post, but I just using the default standard value which I even hardcoded in settings.py, but no luck. I'll attach my gunicorn config/logs below: config: ./gunicorn.conf.py wsgi_app: None bind: ['0.0.0.0:8000'] backlog: 2048 workers: 2 worker_class: sync threads: 4 worker_connections: … -

Converting a static HTML website into a fully fledged Django project
I am just getting started with Django. I have a situation where I have a project consisting of a large number of static HTML Pages compiled over time. Now I am in a situation to use a framework and I have opted for it. However I can't just write the whole project in Django because the large number of pages is being a problem for me and my team. As you know maintaining each one is a tedious task and not practical at all for me. So if anyone could suggest a tool or a script to convert entire static website into a Django project will save me a lot of time. Every solution is appreciated. -
Azure B2C : Error in the callback after the edit profile when it tries to get a new token
I try to implement an azure B2C authentication in Django. Unfortunately, there is not much documentation in Django on this topic. However, I managed to write the functions and views to get an id_token and store the user's information in the session. I wanted to integrate the edit profile with the specific authority. The page is perfectly redirected to update the user information. However, after the validation of the new data, I get an error message in the callback when I try to get a new token (function _get_token_from_code). {'error': 'invalid_grant', 'error_description': 'AADB2C90088: The provided grant has not been issued for this endpoint. Actual Value : B2C_1_signupsignin_20220810 and Expected Value : B2C_1_profileediting\r\nCorrelation ID: xxxxxxxxxxx nTimestamp: 2022-08-31 14:58:54Z\r\n'} So it implies the following error in the python execution : _store_user(request, result['id_token_claims']) KeyError: 'id_token_claims' However the new information of the user are correctly saved in the azure. Since I am newbee in this authentication process ? Do we need to generate a new token for the edit profile user flow ? Where does come from this mistake ?

How to compute cumulative sum of a count field in Django
I have a model that register some kind of event and the date in which it occurs. I need to calculate: 1) the count of events for each date, and 2) the cumulative count of events over time.
