Using Django JWT authorization for FastAPI endpoint
I have a Django app where I use SIMPLE_JWT to authenticate users. I use Django to work with the admin panel, in addition, I use the Django rest framework to transfer data to the React frontend application. During authorization, the React application receives a JWT token, which is then passed along with any requests to Django rest framework endpoints. Now there is a need to create a new FastAPI endpoint. Is there any way to make FastAPI use the same JWT tokens that the Django application accepts (and creates) to check whether the user is authorized and has access rights to the FastAPI endpoint? How to do it most correctly? -

Safely store data from GET request - Django
Alright, Let's say we need to create a website with Django where people can book a lodge for the weekends. We add a search form on the homepage where people can fill in the check-in and check-out date to filter for all available lodges. We use a generic Listview to create an overview of all the lodges and we overwrite the queryset to grab the search parameters from the GET request to create a filtered view. views.py class ListingsView(ListView): """Return all listings""" model = Listing template_name = 'orders/listings.html' def get_queryset(self): """ Visitors can either visit the page with- or without a search query appended to the url. They can either use the form to perform a search or supply an url with the appropriate parameters. """ # Get the start and end dates from the url check_in = self.request.GET.get('check_in') check_out = self.request.GET.get('check_out') queryset = Calendar.objects.filter( date__gte=check_in, date__lt=check_out, is_available=True ) return queryset Now this code is simplified for readability, but what I would like to do, is store the check-in and check-out date people are searching for. Updated views.py class ListingsView(ListView): """Return all listings""" model = Listing template_name = 'orders/listings.html' def get_queryset(self): """ Visitors can either visit the page with- or … -

DJango admin is serving static files from /media instead of /static
When I run my django app in production mode (ie without DEBUG), my admin site tries to serve static files from "/media" instead of "/static", which causes 404s This is what it's trying to serve. GET https://<domain>/media/admin/css/base.css But if I manually type in https://<domain>/static/admin/css/base.css It serves the static file correctly. So my "collectstatic" is working fine, but somehow the admin site is trying to serve from /media. I don't understand what settings would cause this. Everything I search for related to this is from before django 1.4 where there was a specific setting for admin media url. Other than that I don't see anyone else having this issue. I'm loosely following https://github.com/cookiecutter/cookiecutter-django and I'm on the latest version of django right now. I'm not sure what else to look for -

cannot connect to the backend server running port 8000 using nginx, django and docker
I've spent two days trying to figure this out. I'm running docker containers that host a django+react website from a docker compose file. I can access the website on port 80 (IP: http://52.90.163.11:80), but I can't seem to access the django admin panel on port 8000 (IP should be http://52.90.163.11:8000 but it doesn't work).

Django ORM not releasing memory even when garbage collector is called explicitly
