Open Source Django Projects for Study

Hello everyone,

I'm looking for open source projects made using Django, preferably Django REST Framework, that fix real business problems, and whose code I can analyze, get ideas and learn from.

So far I've got GitHub repositories of Saleor, Django CMS, Wagtail, and a few more, but I would like to see a solution like an inventory management system of a company, HR system, an API that manages data of a game server, something like that, but I guess anything you find interesting or worth seeing could help.

I know that companies wouldn't release their code like that, but there are probably open-source solutions released to the public somewhere on the internet.

So, are there any repositories you could recommend for analyzing, and learning Django a little more in-depth?

Thanks!

Web app with JavaScript

Hi!

I need some advice. For my portfolio I want to build a web app for my national sports team. A bit like a news website but with some more features. I know Flask already and want to work on my JS skills also. I get confused when reading to use Flask for the backend and JS for frontend. I built Flask only apps without any JS. What will be different when using JS too? Are redirects, form submissions, validations, etc.. still handled by Flask? Do people still use jinja and what would be things I've done normally with Flask and now with JS?

Thank you!

Is it Bad to have gunicorn --reload option enabled in Production?

Is there any downside to having the --reload option enabled for Gunicorn in production? For example, does it require additional memory or CPU or anything? I imagine it must have to poll for changes to files.

I created some code to test the search functionality for elasticsearch to have a better understanding of the code. I wrote the code quickly so it is crappy code but it mostly runs . The problem is when I run the code and click search nothing appears. I assume it is the html causing the problems.

Can someone help fix the errors?

​

I am following this tutorial https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-xvi-full-text-search

​

​

​

To save time here is my environment.yaml code

name: py
channels:
- defaults
dependencies:
- python
- flask-wtf
- flask-sqlalchemy
- flask-login
- elasticsearch
- flask-migrate
- bcrypt
prefix: C:\Users\user\Anaconda3\envs\py

Also of important note I just want to state that I manually added the Post columns by using the code below in the command line.

​

from app import db, app
from app import User, Posts
with app.appcontext():
post = Post(title='The Second Posts', body='Here is the body text')

​

I also tested to see if the column was added and it seems to be by using the example below.

​

from app import Post
post = Post.query.filterby(body='Here is the body text').first( )
print(post)
print(post.title)

stacked quantiles

This is going to be niche, but just in case. I use this code a lot, so I uploaded it. For those of us who work with pixels and such where you might have 10k of the same value.

ShayHill/stacked\_quantile: Treat weighted values as multiple values. (github.com)

​ 'Stacked' quantile functions. Close to weighted quantile functions.

These functions are used to calculate quantiles of a set of values, where each value has a weight. The typical process for calculating a weighted quantile is to create a CDF from the weights, then interpolate the values to find the quantile.

These functions, however, treat weighted values (given integer weights) exactly as multiple values.

So, values (1, 2, 3) with weights (4, 5, 6) will be treated as

(1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3) If the quantile falls exactly between two values, the non-weighted average of the two values is returned. This is consistent with the "weights as occurrences" interpretation. Strips all zero-weight values, so these will never be included in such averages.

If using non-integer weights, the results will be as if some scalar were applied to make all weights into integers.

This "weights as occurrences" interpretation has

A heavily tested (2k lines) and commented classic Red Black Tree implementation in Python and Ruby. Great for learning the material.

Back when I was trying to implement the structure, I could not find any open source implementations that were well written and commented.
I did not manage to find any implementation that had any significant amount of tests and as such was not sure if it even worked correctly.
I tried my best to describe the different operations needed thoroughly and have written a lot of tests (functional too) covering all operations, with drawn out trees in comments.

Using Gaussian Elimination instead of a Monte Carlo simulation?

Using Python or R (or another program), let’s say I have two CSV sheets. One has a sample and the other is a reference sheet ( illustrated here: https://i.imgur.com/duNFu3w.jpg <-Sample

https://i.imgur.com/Ar9lO9Y.jpg <- Reference ). The sample is represented by numbers under element categories (Iron, Copper etc).

I want to get the sample classified in terms of percentages of the reference sheet categories. The output would be something like this for example: sample is “ 71% Category15, 8% Category9, 21% Category6. “

I have an existing Monte Carlo simulation in R and the process is slow and doesn’t yield results that are too accurate.
What alternatives exist to using a Monte Carlo simulation on this?


An existing Monte Carlo simulation would run combinations of the categories in the reference sheet to reach a combination similar to that in the Sample, so preferably the alternative would have a computationally similar output.

Can Flask Simply Run My Python Code?

Hi all,

I have a fairly simple python script (its a single class, about 200 lines) that helps me do my job and I want to share with members of my team and am unsure the best way to do this.

Some (important?) details:

1. The program does have a few user inputs and will return a single word/number (based on the inputs)
2. The other members of my team are NOT technical users - I would not trust them with having to install python or running anything from the terminal or an IDE.
3. security is not any security concerns here - anyone can see the source code (but am curious if you are able to see source code in flask)

I'm fairly proficient in python, but have never wanted to share a program with someone who's unable to run a .py file. I think a web app might be the best way to allow the non-technical users to access the program, but am unsure what might be the simplest way to create that? Currently I run the program in my terminal if that helps.

Would this be a good use case for Flask? Most tutorials I see online for flask seem to be blogs
