QUESTION
I get this Error when I try to install Pyodbc , I have already install visual studio and I have Microsoft Visual C++ 12 , 15-19 in my machine but still its giving this error.
...ANSWER
Answered 2021-Nov-12 at 13:38The current release of pyodbc (4.0.32) does not have pre-built wheel files for Python 3.10. The easiest way to get it installed at the moment is to download the appropriate wheel from
https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyodbc
and then install it. For example, if you are running 64-bit Python then you would download the 64-bit wheel and use

You could create a user and install to that users's home directory by doing something like this;
QUESTION
After upgrading to Django 4.0, I get the following error when running python manage.py runserver
ANSWER
Answered 2022-Jan-10 at 21:38django.conf.urls.url() was deprecated in Django 3.0, and is removed in Django 4.0+.
The easiest fix is to replace url() with re_path(). re_path uses regexes like url, so you only have to update the import and replace url with re_path.
QUESTION
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
gunicornanduvicornthrough pip - I have created an
asgi.pyfile with the following contents
ANSWER
Answered 2022-Feb-06 at 21:43When running the gunicorn command, you can try to add workers parameter with using options -w or --workers.
It defaults to 1 as stated in the gunicorn documentation. You may want to try to increase that value.

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.

QUESTION
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
...ANSWER
Answered 2021-Oct-03 at 05:57This is because of a root CA Let’s Encrypt uses (and Mongo Atals uses Let's Encrypt) has expired on 2020-09-30 - namely the "IdentTrust DST Root CA X3" one.
The fix is to manually install in the Windows certificate store the "ISRG Root X1" and "ISRG Root X2" root certificates, and the "Let’s Encrypt R3" intermediate one - link to their official site - https://letsencrypt.org/certificates/
Copy from the comments: download the .der field from the 1st category, download, double click and follow the wizard to install it.
QUESTION
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:

Answered 2022-Jan-19 at 09:20You could use django's receiver annotation.

QUESTION
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.
...ANSWER
Answered 2021-Dec-26 at 19:53You should use an object store to save and serve your user uploaded files. django-storages makes the implementation really simple.
If you don’t want to use cloud based AWS S3 or equivalent, you can host your own on-prem S3 compatible object store with minio.
On your current setup I don’t see any easy way to fix where the number of vm s are dynamic depending on load.
If you have deployment automation then maybe try out rsync so that the vm takes care of syncing files with other vms.

Install django
You can use django like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
