django | My personal opinionated django template | GraphQL library

I am making simple image of my python Django app in Docker. But at the end of the building container it throws next warning (I am building it on Ubuntu 20.04):

After upgrading to Django 4.0, I get the following error when running python manage.py runserver

Question in short

I have migrated my project from Django 2.2 to Django 3.2, and now I want to start using the possibility for asynchronous views. I have created an async view, setup asgi configuration, and run gunicorn with a Uvicorn worker. When swarming this server with 10 users concurrently, they are served synchronously. What do I need to configure in order to serve 10 concurrent users an async view?

Question in detail

This is what I did so far in my local environment:

• I am working with Django 3.2.10 and Python 3.9.
• I have installed gunicorn and uvicorn through pip
• I have created an asgi.py file with the following contents

I would like to send a PATCH request to my app but I'm not sure how to consume the request in Django. I am currently getting the following error.

I am using MongoDB(Mongo Atlas) in my Django app. All was working fine till yesterday. But today, when I ran the server, it is showing me the following error on console

I would like to automatically generate some sort of log of all the database changes that are made via the Django shell in the production environment.

We use schema and data migration scripts to alter the production database and they are version controlled. Therefore if we introduce a bug, it's easy to track it back. But if a developer in the team changes the database via the Django shell which then introduces an issue, at the moment we can only hope that they remember what they did or/and we can find their commands in the Python shell history.

Example. Let's imagine that the following code was executed by a developer in the team via the Python shell:

I'm trying to get a django project up and running, which depends on GDAL library. I'm working on a M1 based mac.

Following the instructions on official Django docs, I've installed the necessary packages via brew

We have deployed a django server (nginx/gunicorn/django) but to scale the server there are multiple instances of same django application running.

Here is the diagram (architecture):

Each blue rectangle is a Virtual Machine.

HAProxy sends all request to example.com/admin to Server 3.other requests are divided between Server 1 and Server 2.(load balance).

Old Problem:

Each machine has a media folder and when admin Uploads something the uploaded media is only on Server 3. (normal users can't upload anything)

We solved this by sending all requests to example.com/media/* to Server 3 and nginx from Server3 serves all static files and media.

Problem right now

We are also using sorl-thumbnail.

When a requests comes for example.com/,sorl-thumbnail tries to access the media file but it doesn't exist on this machine because it's on Server3.

So now all requests to that machine(server 1 or 2) get 404 for that media file.

One solution that comes to mind is to make a shared partition between all 3 machines and use it as media. Another solution is to sync all media folders after each upload but this solution has problem and that is we have almost 2000 requests per second and sometimes sync might not be fast enough and sorl-thumbnail creates the database record of empty file and 404 happens.

Thanks in advance and sorry for long question.

I'm build Django app, and it's work fine on my machine, but when I run inside docker container it's rest framework keep crashing, but when I comment any connection with rest framework it's work fine.

• My machine: Kali Linux 2021.3
• docker machine: Raspberry Pi 4 4gb
• docker container image: python:rc-alpine3.14
• python version on my machine: Python 3.9.7
• python version on container: Python 3.10.0rc2
