Celery Broken After Upgrading DJ to 3.1

Hello everyone,

I was running Celery 4.4.7 when I upgraded Django to 3.1. This ended up breaking it, and in `/var/log/celery/proj_worker.log` I got the error `ImportError: cannot import name '_lazy_re_compile' from 'django.utils.regex_helper'`

To attempt to resolve this, I've upgraded celery to 5.0, but now none of my tasks work at all.

When I run `celery -A proj beat -l debug`, celery beat does not start, saying:

celery beat v5.0.5 (singularity) is starting.

os.path vs pathlib?

One short question, how and when do you use this modules?

​

For a very long time I only used os.path, but recently I discovered pathlib. My short answer:

os.path, if I just want to check if the path exists or just a few actions.

And pathlib for complicated tasks, like a base folder in various functions or class.

​

What do you think about this?

SimpleGUIBuilder - A GUI for designing Python GUI's for PySimpleGUI

Hello Python people :)

I don't really like doing frontend but I really like the idea of giving my backend/terminal programs something more pleasurable to interact with and look at.

That's when I came across PySimpleGUI, a simple solution to quickly give my programs an interactive front. Shortly, it allows you to quickly create a GUI by designing its layout and then map it to your backend code.

But in checking it out I found I wanted more and had an idea: It would be nice if PySimpleGUI and therefore GUI making was in itself more interactive.

And that's how SimpleGUIBuilder came to be: A GUI for creating/designing GUI layouts for PySimpleGUI, made with PySimpleGUI.

I hope this will be useful to people :)

You can get it in the releases and check out more info here in github.

AF Questions on a github repo / second guessing myself for a job interview

Hello,

I’m interviewing for a flask developer position and part of the process is this:

“Use Case: Building a Cloud Portal

After looking around to leverage other gov code, you find an available repo to use as a portal for your future cloud portal. Before using it, you want to review the instructions, deploy the system locally to your computer, and provide technical feedback on the README.md file that you could use to streamline the local deployment of the application.

After getting the system running, you are excited to show your work and setup a demo for the application for us to see.

The repo is locating here: https://github.com/dod-ccpo/atst”

After attempting to deploy this application on multiple systems (mac os, windows, linux and docker) I’m unable to for a multitude of reasons,

My questions are the following: Is this code base fucked or what? What’s the point of using poetry (first time ive ever seen it) when better alternatives exist? Why reinvent the wheel? Why the hell would you want to use one script rules them all? Is this repo a test and it’s not meant to at work at all and they want to see what I say?

And also, for the record the docker deployment doesn’t

Show profile page after login

If possible I'd like some help with a little self-teaching project. So I was following flask's own tutorial to build a blog. See here. I've managed to get the login and registration pages up and running with a connection to a mariadb server sitting on a raspberry pi in my network.

So I decided to expand on it to create a profile page which requires the user to be logged in to view. I created a new py file and a new html page to display this profile page. However, when I add the @loginrequired to the blueprint route for the profiles page it throws an app.context error.

Profile page code snippet

@zerg.beforeapprequest
def loadloggedinuser():
userid = session.get('userid')

if userid is None:
g.user = None
else :
db = getdb()
cur = db.cursor()

My startup failed, so I open sourced the code. I hope someone finds it useful.

Best way to display python code and graphic outcomes in a Django site?

If I want to display some python code, and its resulting output and graphs as part of a Django page (I haven't decided if the visitors can or cannot modify the code, and rerun), what is the best way to do it? If I allow visitors to tweak the python code to see different output or graphs, is it really risky as a site security point of view?

Creating a scalable Flask Application

We have a large flask application containerized using docker, different services are exposed via different endpoints. The application has a total of 5 containers with multiple deep learning models

The system is supposed to get data in large bulk, so it should be able to use hardware at full capacity on heavy load

I researched and found some ways (mentioned below) to make application scalable but which one to choose

​

1. Gunicorn
2. Docker swarm
