How to deploy Django on VPS?

I purchased a VPS in Hostinger in order to deploy a django app, I haven't found any updated guides except this one: https://holamundo.io/2023/06/09/como-desplegar-tus-apps-de-python-con-hostinger-y-github-actions/

Still, I got to the part where I have to make the LiteSpeed point to my project:

Google ads API not running on admin pod but is running on celery worker

So basically the title,

I am working on a project where I need to run a custom method in Django admin of some model, in this method I am acquiring a connection to the Google ads API and making a request to create something. While running this method in the admin pod, the process got stuck, but when I made a celery task it was fine and worked just as I expected, this is not the first project that this problem happened to our team, I couldn't find any explanation and I was wondering why did it happen, would love to get you insight on it.

miniloop: a minimal, pedagogical event loop implementation

https://github.com/roee30/miniloop

The PEPs introducing the async/await syntax don't specify exactly how event loops work, considering it an implementation detail. If you are curious about how event loops work in Python, you might have noticed that reading through asyncio's code is challenging, to say the least.

That's why I have created a minimal event loop implementation with step-by-step explanations. It shouldn't be used for anything other than learning purposes. It is 362 lines in size, but many of them are documentation. Before diving in, make sure you understand generators. You can use the server.py script to see the loop in action.

The implementation is inspired by asyncio, but I only added what was necessary in order to make a simple server work. In particular, my Task and Future are roughly analogous to asyncio's, but I didn't find a need to implement Handles (perhaps because I didn't implement the call_* methods).

I learned a lot writing this and I hope it will be useful to others as well.

Deploy Flask-app on IIS?

Hi all,

I have a simple Flask-app with the following structure that works fine locally on my machine:

\- app.py
\- static (folder)
\- scripts.js
\- styles.css
\- templates (folder)
\-index.html

app.py looks like this:

from flask import Flask, render_template

app = Flask(__name__)

# Ensure templates are auto-reloaded
app.config["TEMPLATES_AUTO_RELOAD"] = True

# Define the index page
@app.route("/", methods=["GET"])
def index():
resources = ['listhere']
instances = list(range(1,100))

# Add leading zero to first 10 digits

instances[i] = "0" + str(i + 1)

# Sort all lists just in case

Django GraphDB

Hi everyone - never did a big Django project before but now I plan to start one which might grow in the future. It is an internal app and it will need to do some operations with Neo4j. My question is: is Django my best option or should I use another framework? I will need the basic admin over users etc but in terms of ""additional"" databases, I need to build a knowledge db with Neo4j (or any alternative graphdb). thanks in advance :)

pytest parametrize vs highly repetitive code?

In pytest ... or, for that matter, in the world of QA automation ... the coder is usually given the ability to parameterize variables that control the test cases. But at what point of adding successive parameters does this become overkill? What are your rules-of-thumb when deciding to write another test function or add a parameter (and perhaps an if-statement or more) to an existing test function?

I've always leaned toward the parameterize approach, only to, in the end, wish I hadn't made the primary test function so complicated and full of special-case if-statements. Having four or even eight nearly-identical test functions goes against the code-reuse theme that permeates s/w engineering. But sometimes code repetition is both easier to read and maintain - particularly in the domain of writing test automation.

Which one is preferred: self.state.adding VS not self.pk?

I'm going to do some checks before object is saved in DB and I just came across this:

if self.state.adding: # do something

which I never used before. I only used:

if not self.pk: # do something

are they functionally equivalent for identifying new model instances? Does one method have advantages over the other in certain scenarios? Seeking insights on best practices and functional differences, if any.

Which one is preferred generally?

How to configure django-markdown-editor to save upload images to local storage

Hi there,

Here is what is working:

* Create an new Django app, installed & configure with django markdown editor ([https://pypi.org/project/martor/](https://pypi.org/project/martor/)). register the application at [https://api.imgur.com/oauth2/addclient](https://api.imgur.com/oauth2/addclient) to get IMGUR\_CLIENT\_ID & IMGUR\_API\_KEY. It is working with no issue when uploading image but it saves to imgur's website ([https://i.imgur.com/dqHGHXp.jpg](https://i.imgur.com/dqHGHXp.jpg))

&#x200B;

Here is not working:

I tried to configure & save the uploaded images to local storage based on it's wiki but it does NOT work

[https://github.com/agusmakmun/django-markdown-editor/wiki](https://github.com/agusmakmun/django-markdown-editor/wiki)

I have the following in my app's [urls.py](https://urls.py) but it never call "markdown\_uploader" function

\# [urls.py](https://urls.py)

urlpatterns = \[path('api/uploader/', markdown\_uploader, name='markdown\_uploader\_page'),\]

\# [views.py](https://views.py)

\# @ login\_requireddef markdown\_uploader(request):

print("got here???")

....

Has anyone able to save the upload images to either local storage or AWS S3?

htmx or basic javascript?

almost finished a js course, and want to dive into learning django. was thinking of doing react until I found out about htmx. Here's the thing, can I skip htmx completely and just focus on basic js, since from some of the posts on this sub I hear that while htmx is great its not comprehensive like js. so if i've already invested time in js, can I just focus on that as everything htmx can do - js can do, but everything js can do - htmx can't do?

really knew to this stuff, dont want to invest time in something that i don't need.

Flask-Muck: Flask REST Framework that generates complete CRUD APIs for your SqlAlchemy models in as little as 9 lines of code.

"With Flask-Muck you don't have to worry about the CRUD.

Flask-Muck is a batteries-included framework for automatically generating RESTful APIs with Create, Read, Update and Delete (CRUD) endpoints in a Flask/SqlAlchemy application stack."

Links: GitHub \- Documentation \- PyPi

&#x200B;

After years of working in Flask/SqlAlchemy/Marshmallow apps I felt like there was a large gap in the tooling for creating standard REST APIs that perform basic CRUD operations. Especially when comparing it to the Django ecosystem. I'm hoping this can remove large amounts of boilerplate for folks and get some projects bootstrapped and off the ground much more quickly.

The library has just been released so I'm leaving the beta tag on the pypi releases for a bit until I get some strong feedback. I'm currently looking for early adopters to use it in personal/side projects.

If anyone would like to take it for a spin and report back on any missing features or bugs I'd love to work with you. I don't have much to offer but would be happy to credit you as a contributor to the project.
