Looking for a Django package to quickly add a blog to my existing project
Hey everyone!
I'm currently running a Django project and would like to add a blog feature to it. Is there a package or app that I can install to quickly set up a blog? Ideally, I'd want something that is easy to integrate into my existing project and doesn't require a full rebuild. Any suggestions for good blog packages, or should I just build one from scratch? Thanks in advance!

Cannot send JSON with template
I have a problem where it keeps escaping the quotation marks.
This is my code:
@app.route('/')
def home():
gameslist = {"message": "Welcome to the Game Submission Page!"}
dump = json.dumps(gameslist)
return rendertemplate('index.html', initialdata=gameslist)
and in my html
<script>
const initialData = "{{ initialdata }}"
console.log(initialData)
</script>
Console.log(initialData) produces "{\'message\': \'Welcome to the Game Submission Page!\'}" regardless if I use json.dumps or not.
When I try "{{ initial_data | tojson }}" (also with "| safe") I get "Unexpected token '{'" when using json.dumps and without json.dumps I get "Unexpected identifier 'message'"
What am I doing wrong? Thanks.

ryp: R inside Python
Excited to release ryp, a Python package for running R code inside Python!
[https://github.com/Wainberg/ryp](https://github.com/Wainberg/ryp)
ryp makes it a breeze to use R packages in your Python projects.
**What My Project Does**
ryp is a minimalist, powerful Python library for:
* running R code inside Python
* quickly transferring huge datasets between Python (NumPy/pandas/polars) and R without writing to disk
* interactively working in both languages at the same time
**Target Audience**
Data scientists and engineers, bioinformaticians, Python package developers, ...
**Comparison**
ryp is an alternative to the widely used [rpy2](https://github.com/rpy2/rpy2) library. Compared to rpy2, ryp provides:
* increased stability
* a much simpler API, with less of a learning curve
* interactive printouts of R variables that match what you'd see in R
* a full-featured R terminal inside Python for interactive work
* inline plotting in Jupyter notebooks (requires the `svglite` R package)
* much faster data conversion with [Arrow](https://arrow.apache.org/) (also provided by [rpy2-arrow](https://github.com/rpy2/rpy2-arrow))
* support for *every* NumPy, pandas and polars data type representable in base R, no matter how obscure
* support for sparse arrays/matrices
* recursive conversion of containers like R lists, Python tuples/lists/dicts, and S3/S4/R6 objects
* full Windows support
ryp does the opposite of the [reticulate](https://rstudio.github.io/reticulate) R library, which runs Python inside R.

Any state machine fans out there? Got any fun/awful stories?
I first started to appreciate finite state machines about 15 years ago when I was creating a custom radio protocol for low speed long distance links. Nothing too fancy, but the protocol had retries and acknowledgements. Like a tiny TCP stack.
About 8 years ago I became a state machine nerd out of necessity at work. Sink or swim. Although it was hectic, it pushed me to create a very useful state machine tool.
# The frickin huge LCD GUI
My first project at a new company was very ambitious for a solo dev. In a short amount of time, I needed to create a custom user interface for a 2x20 character LCD that had a lot of different menu pages. 107 pages in total, arranged into different hierarchies. Some of the menus were calibration and setup wizards. Some showed live data. Some were interactive and allowed editing parameters. Each of those 107 pages also needed to support multiple languages (English, German, Russian, Spanish).
A previous developer (that quit before I joined) had tried a data driven menu approach. They defined the entire menu layout and page transitions in data. This made perfect sense for a while until the client started adding tricky requirements

Rant of the Day
3 years ago I was working in tax when I got a taste for the potential of Python for problem solving. I got hooked and spent as much time as possible to understand Python for data analytics. I love using Python, idk but the feeling I get when a piece of code (written shitty) actually works....ahhh its amazing.
Kinda like Frankenstein.... "IT LIVESSSS!" Basically i really enjoy creating and solving problems with it.
Fast forward 3 years, and I managed to get a position of Senior Manager on Data Management, thinking ah yes finally I get to work on the things I like.
8 months in and I have YET to write a piece of code. Literally my entire time is spent replying to emails, fixing problems other people cause, having to deal with office drama, never ending meetings and top management seem to never be able to decide on anything. The amount of issues that come up on a daily basis is nuts and I never have time to sit down and be creative. Yesterday I lost my shit during a useless 4 hour meeting that could have been solved easily with a well

Introducing ZipNN: A Python Library for lossless Compressing tailored for AI Models
**What My Project Does:**
ZipNN is an open-source Python library that enables lossless compression of AI models, **reducing their size by 33% with BF16 format (yes, also Llama3.2)**. Effectively cutting down download times and easing the load on servers. The library integrates smoothly with Hugging Face, with just adding a single line of code. The decompression is fast and there are already compressed Models on Hugging Face that you can try right away and save time.
**Target Audience:**
ZipNN is developed for **AI researchers, data scientists, and software developers** who manage large neural network models. It is particularly useful for those seeking efficient ways to handle model size constraints in both academic and production environments. The library aims to facilitate better resource management without sacrificing the accuracy of AI models.
**Comparison with Existing Alternatives:**
**ZipNN is tailored for AI models (the NN stands for neural network)** and gives both a better compression ratio and speed.
For example, with BF16, ZSTD (the current state-of-the-art) saves 21%, while ZipNN saves 33%, and compression and decompression are x1.5 faster.
**Additional Resources and Examples:**
* **GitHub Repository:** [Visit the ZipNN GitHub Repository](https://github.com/zipnn/zipnn)

CORS and CSRF Configuration for a Separate Frontend and Backend? Willing to Pay
I have a website I am working on that uses Django and Svelte. Django acts as an API using Django Ninja. The frontend uses Svelte's SvelteKit framework and makes API calls to the Django backed. I have already created a github repo to hopefully make this easier and quicker: https://github.com/SoRobby/DjangoSvelteCookieAuth/tree/main.
The site is intended to be hosted on Digital Ocean (DO) on potentially two separate domains. Example of this would be below, where the frontend and backend are on separate subdomains.
Backend: https://example-backend-8lntg.ondigitalocean.app/
Frontend: https://example-frontend-gbldq.ondigitalocean.app/
Issue: I have been experiencing CORS and CSRF related issues that I can't seem to resolve. The site will use cookie-based authentication.
I have reached my threshold and am willing to pay ($200, via paypal or venmo) the first person that is able to solve these issues without sacrificing security, while remaining on Digital Ocean and deploying as an app and not a Docker container.
----
More details about the problem:
On the backend in settings.py, I have configured CORS, CSRF Cookies, and Sessions.
I am experiencing an issue that I cannot resolve and it relates to an error message of Forbidden (CSRF cookie not set.). On the frontend in Svelte, inside the hooks.server.ts file, whenever the frontend page is loaded,

Get clean markdown from any data source using vision-language models in Python
I have found that quality data preprocessing for LLMs from raw data sources can be an incredibly difficult task, so I'm sharing a new project I began working on this summer to solve this problem.
What My Project Does:
The package in question is an open-source project designed to simplify the process of scraping clean data from various sources (PDFs, URLs, Docs, Images, etc). Whether you're working with PDFs, web pages, or images, it can handle the extraction into a clean markdown format. Unlike traditional scraping tools, it is able to understand the context and layout of documents, thanks to vision-language models. It even handles complex tables and figures.
The beauty of The Pipe is that it's not just a black box. It's open-source so you can peek under the hood, understand how it works, customize it to fit your specific needs, etc. The Python library is quite thoroughly documented for this kind of stuff.
Comparison:
Look at existing Python packages for document scraping such as PyPDF2, Unstructured, PyMuPDF (fitz), PDFMiner, Tabula-py, Camelot, pdfplumber, and marker. While these tools are great at basic text extraction, they often struggle with more complex tasks like handling scanned PDFs, irregular data tables, tables that span multiple pages, and documents

What are your thoughts on using Django as an SPA backend?
I’m leaning more towards FastAPI, so try and change my mind!
For context, the frontend would be a Nuxt SPA with SSR. I like the Django admin and ORM, but building a REST API with Django just seems easier in FastAPI. I’d be using Django Ninja as I don’t want to pay for Django Rest Framework if I monetize the app (I can’t get past the “strongly encouranged to sign up for a paid plan” if the app is commercial).
Would you use Django or FastAPI for building the backend for an SPA?

Beginner Question - Why API?
I've recently been learning Django via tutorials and books solely as a personal challenge as I don't use coding in my career. That said, I am struggling to understand why REST API's (or API's in general), exist. I have created a blog API in a tutorial, but why? Beyond extracting data from a huge database, why isn't a regular website with data presented in html sufficient? As a corollary, what would be a good personal project that could utilize an API vs./on top of a standard django website?

Why use Django when we have FastAPI for small userbase applications
People often mention that Django comes with ORM and admin support. However, I can use SQLAlchemy or raw SQL queries as well. While Django has built-in admin features, FastAPI offers a full-stack template repository with React, which has pretty decent features that meet most requirements. FastAPI is also fast due to its asynchronous nature and has a growing, enthusiastic community eager to help.
Am I wrong in saying this? Give me good reasons to use Django.

Paramorator – Simplify Parametrized Decorators, Make Type Checkers Happy ✅
In almost every project I work on I end up needing to create parametrized decorators at some point. That is, a decorator that can accept arguments before you tack it into the function or class you want to wrap. For example:
@database_session
def get_data(session: Session, key: str) -> dict[str, Any]:
...
@database_session(privileges="read_write")
def save_data(session: Session, data: dict[str, Any]) -> None:
...
It's not exactly rocket science, but to do this in a way that will make type checkers and IDEs happy can be a bit of a pain. [Paramorator](https://github.com/rmorshea/paramorator) is a dead simple (<100 line) library I created that makes that process a little easier. Here's how you could use it to implement the `database_session` decorator above:
from functools import wraps
from typing import Callable, Concatenate, Literal, ParamSpec, TypeVar
from paramorator import paramorator
from sqlalchemy.orm import Session
P = ParamSpec("P")
R = TypeVar("R")
