I had a perfectly running django project.
But today it started getting stuck at collectstatic
On the production env it does not get ahead of collectstatic command and remain freezed forever.
While the collectstatic command runs fine when I run it locally.
My static dir and all are correct as the project was working fine with static files since last few months.

Hey men I created a project on Django, pushed it on github on Ubuntu 20. I made pipenv also. Now, when downloading it on to my Windows computer, I try executing 'pipenv shell' but it says 'Failed to create virtual environment'. It causes Filenotfounderror - can't find python way. Can you please help me with it? Thanks

Did you use STATICFILES_DIRS or in urls.py added some dirs as 'urlspatterns = [ ] + ...' ?

get queryset is not a create method of instances

If I fetchall in Postgresql, there is only one result, but there are 2 records in the database. What could be the reason?
def topadders(self,chat_id):
cur = DB().connect()
cur.execute("SELECT * FROM table WHERE group_id = '"+str(chat_id)+"' ORDER BY soni DESC LIMIT 20;")
curr = cur.fetchall()

Hi. Is the async support in Django 3.1 deals the same thing as the ASGI capability in Daphne?
I mean, if I turn from ASGI/Daphne to Apache mod_wsgi, will the async support in Django 3.1 be turned off?

imacat
Yes
Well, thanks. I shall turn from Daphne to mod_wsgi, since the 3.1 async support breaks my code and I cannot find a simple way to fix it.

I shall try to turn to mod_wsgi tonight first, and then study how to adapt async in Django 3.1. It does not make sense if I have to adapt codes that I can only test and verify on the production server.

Is there a way to block django superuser from doing things that a normal(non-staff/non-SU) can do?

I think 'groups' and permissions is a way to achieve this but can anyone guide me and give me some specifics on the permission that I'll need to set to do so

It doesn't make sense imho, a superuser is a superuser so it's aim is to handle everything

didn't make sense to me too, but my seniors think that allowing superuser to do normal stuff sometimes messes up things on the long run when the project scales

They're from java(spring hibernate) background, maybe there's such problem in java frameworks but not in django?

It doesn't mess up anything if the superuser privileges are assigned to smart people
Tell your seniors there's a reason why we call it superuser, if they don't wanna give all of this privileges , create a user with proper permissions

Do anyone have knowledge of mongodb?
Mr. D @
hey,
what do prefer to use with django?
Nginx with Gunicorn OR openlitespeed (or apache..)?
with openlitespeed there is not need for gunicorn and some benchmarks shows its faster.
what do your think?
Sh
Assalamu alaikum.
I read this article
Task Queues: Another example is when a database query would take too long during the HTTP request-response cycle. The query could be performed in the background on a fixed interval with the results stored in the database. When an HTTP request comes in that needs those results a query would simply fetch the precalculated result instead of re-executing the longer query. This precalculation scenario is a form of caching enabled by task queues.
Any examples for that?

nice. did you setup/configured yourself? used a docker image or script?
uWsgi seems hard to configure.

there's plenty of free resources to learn django.
personally I've bought a course on udemy for a few sheckels - ended up following a course on youtube (by "the net ninja", if admin allows me to link it, I'll pass it on).

You can find it on lib genesis if available

Celery is the most used solution for this kind of scenario in python infrastructures. It is a general approach that is used ETL, ELT, and ESB scenarios that will feed an enterprise Business Intelligence platform too. Some of the SQL level calculations or Big data (Hive, Spark etc.) calculations take much time. A task queue mechanism -such as celery- runs a long-running task in its workers -in background-. You can schedule these jobs in order to cache possible outputs on an interval.

good and very understandle👍
after calculation big sql, do I need simply save date to db for caching?
Mehmet
It is up to your needs actually. If your result set is high dimensional, you may use OLAP cubes or relational backend. If it is pointer-based data such as the calculated rank of every single user, you may use NoSql solution or cache backend such as Redis.
Andrej

uWsgi seems hard to configure.
The book "High Performance Django" helped me a lot to configure uWsgi and speed up my application.
Biagio
Just one question: is there a django framework that allows me to have a backend just like WordPress? Or simply let me skip some development phases?

Mehmet how did you learn Django? I want to learn but i cant find any source extremely
I have learned Django after professional development experience in Java Spring MVC/Spring Boot on some enterprise projects for insurance companies in Turkey. I have only used https://www.tutorialspoint.com/django/index.htm in order to get used to Django's design patterns. Following that all I did was re-implementing some of my personal projects in Django and using stackoverflow to solve my basic problems, reading up Medium articles to learn pythonic ways of handling advanced webapp issues such as task queueing, authentication authorization pipelines, Db performance tweaking, caching strategies. I love reading articles on metrobusses in Istanbul and all I did was reading. I personally cannot integrate myself into a tech stack without using it in a real project with time/cost/scope constraints 😂
Mehmet
It is against the rules of the group to promote a page I guess. I write a blog in Turkish about python.
Enes
Wow that's good mehmet. I am also in Istanbul. But i wasn't thought you are in Turkey

You have a history of programming. This is an advantage for you. You are luck
