I built a platform for helping Django developer to find a new job.. and it's work pretty well !

Hey r/Django :),

I'm a freelance Django dev and I'm making some side projects (Big fan of the indie hacking movement)

My last one is a platform for helping Django developers to find a new job or a new freelance contract (https://www.djangotop.com).It's 100% free. I put it online 1 month ago and I already have 70 devs that are signed up :D (and 2 found a job !)

Do not hesitate to give feedback and if you are interested, create your profile ! It helps me to be able to bring back more traffic from companies interested in Django developers !

If you want to test it out you can dm me and I will send you an invite link.

Any feedback on the landing page is welcomed. I kinda need some help to figure out how to make it better.

Related object is literally being saved immediately above but still getting "ValueError("save() prohibited ... unsaved related object 'url'.")

Django==4.0.7 (I can't use 4.1 yet because of django-celery-beat not working with 4.1)


Getting this error for a updateorcreate() using a related object (code line 392). Django thinks it's unsaved but it's literally being saved right above it. This only happens when the get() fails and I'm creating the object after URL.DoesNotExist is caught. If the get() works the updateorcreate() is handled without issue.

How can I save it more than it's already being saved? :-)

(Traceback is at the bottom of this post)

Code:

How to reformat IPYNB files for JSON compatability?

When dragging and dropping the .IPYNB file in Jupyter Notebooks, I get an error...

The error was: SyntaxError: Unexpected end of JSON input

when inspecting the properties I see:

\-------------

Type of file: IPYNB

Location: 04/demos/demo/titanic/notebooks/

size: 82 KB

compressed: 25 KB

Method: Deflated

CRC-32: 5570B0C4

Index: 420

\--------------

How can I reformat these files with the correct JSON input so I can use IPYNB files in Jupyter Notebook?

Update DB with new table with SQLAlchemy

So I'm using SQLAlchemy with my Flask web app for database stuff. I tried adding another class to my "models.py" file to make another table for the database, but that didn't work. So, I'd like to ask the proper way of adding new tables to databases with SQLAlchemy.

Cross Data-Base joins on Jupyter Notebook?

Hey all!

I want to create a data extract by joining multiple tables from different databases in order to create a Tableau dashboard. The problem is on Tableau it takes painfully long time to do so. My teammate suggested Jupyter Notebook.


How to do it?? Can someone provide an example?? This will be greatly appreciated! Thanks.

Is it time for Python to have a statically-typed, compiled, fast superset?

I love Python. Really enjoy writing code and cracking problems with Python. I’m by no means an expert (not even close), but have been writing Python for the past 7 years or so (happily).

Now, a few things caught my attention during this time. The first was Rust. It’s amazing how much of a difference it makes to have a powerful compiler and static types and low memory consumption and speed. Sure, Rust is the extreme, but still, a lot to learn here. Not to criticize Python, since the errors have improved drastically, MyPy has evolved significantly, the language is getting faster. But yeah, Rust in a whole new level in several aspects (reinforcing: this is NOT a comparison, but rather a reference).

The other thing that was interesting to me, was the potential of type annotations to help make for a faster, safer experience on the compiler end of things. One example is seen in Meta’s Cinder project, on the docs it explains how typing can be used to reduce the number of steps for the compiler ([cinder/static_python.rst at cinder/3.8 · facebookincubator/cinder · GitHub\](https://github.com/facebookincubator/cinder/blob/cinder/3.8/CinderDoc/static\_python.rst)), making it more effective.

The ecosystem definitely is not lacking on projects: Cinder, MyPyC, Nuitka, PyPy, Pyston,

What do you use to run Jupyter notebook?

I just started learning ML with Jupyter notebook, I am not sure which IDE to use

Jupyter notebook with anaconda seems the simplest but lack intellisense, so I am kinda gravitating toward PyCharm or VS studio code. any suggestion?

I've built an app to show how to build a complete web app

I've built tozo.dev to demonstrate how to build a (Progressive) web app with a Python-Quart backend, and a Typescript-React frontend running in AWS. I've included in the repository, github.com/pgjones/tozo everything needed to reproduce it i.e. all the code, the CI/CD actions, and the Terraform infrastructure definitions.

The commits are ordered and explained, and I hope that you can follow them to build you own app, alternatively you can just take code as a blueprint.

The app itself manages to-dos, but this is just as an example. If you remove this functionality you have an app including user management ready to go.

I use this to help train engineers, and I use (and have used) the stack for production projects.

(I did post about this earlier in the week but I don't think I explained it very well).

Python Turtle (Quick and easy way to visualize, code inside)

Dear Friends,

Wanted to share with you this nice visualization I did with the Python Turtle library.

In this video, I show how to visualize the famous Zeno's Mice problem.

At first, I qualitatively describe the problem,

then show visualization with Python Turtle, code available in the description of the video.

It is mostly based on the code of the python turtle academy.

Then I also show that those curves are actually all around us.

Finally, I show a simple and elegant solution to a system nonlinear system of coupled ordinary differential equations. Using symmetry we can reduce the system to a single equation.

Complex numbers also help simplify the solution.

Finally, I show how such behavior happens in ants in real life.

Enjoy:

Deploying a relatively resource intensive, pre-trained ML model with Django

Hey there Django community!

I have a relatively resource intensive pre-trained ML model as well as a Django website. (Not deployed)

Currently, the inference from the ML model is done in its own .py file in one of the Django apps.

I am wondering if I can deploy the Django website like this without encountering major bills from AWS? Or is there any smarter way of doing it?

I’m new to AWS and deployment in general.

Thanks so much!

Edit: spelling

Django Rest Framework - how to change initial data of a serializer before validating and saving ?

**Intro -** A text snippet has a title, body, author and some tags associated with it. In the post request I send the data like this -

{
title : 'Hello world',
body : 'Some random text',
tags : 'Horror'
}

There are two tables - 1. tags - to store the different tag names and 2. snippet - to store the text snippets. They are linked by a table snippet\_tags which has snippet and tag id as FK.

class Tags(models.Model):
name = models.CharField(max_length=256)
active = models.SmallIntegerField(default=1)
owner = models.ForeignKey(User, on_delete=models.CASCADE)

class Snippet(models.Model):
text = models.TextField()
body = models.TextField(null=True)
owner = models.ForeignKey(User, on_delete=models.CASCADE)
tags = models.ManyToManyField(Tags)
