Intermediate Django Learning

Hello all, I’m looking for advice. I’ve learned the basics of both Django and Node/Express/Mongodb. I want to get more advanced, and python is my main language, so I wanted to continue with Django.

My problem comes with higher level concepts like middleware, cookies, and more (I don’t know what I don’t know), but I cannot find any tutorials or books for getting good at Django intermediate topics. Can anyone recommend any? I’ve found a bunch of tutorials for the JS stacks, but none for Django, and if none really exist I have to continue with JS.

If anyone has any links or tutorials (I’m partial to Udemy courses but have love for books and other types of resources), please let me know, or let me know if this is a bad question for some reason. Thanks in advance!

Quick question about injection vulnerability

I'm very new to this framework so this is probably an easy question. Somehow hard to google, though.

Do I have to worry about injections when using render_template with user input? Let's say I have an index.html file with a <p>Hello { name }</p> section, and then use

return render_template('index.html', name=request.json['name'])

on POST requests.

Django Relationship



Please can anyone help me with this?

I’ve created two models to send data to my database.

A programmer model that stores the values of a programmer like name and age with other stuff.

Then another model that stores the code a programmer writes.

I’ve created the templates for both models - details and everything.

I want to be able to give users the ability to click on a programmer name then see the codes he’s written, note the programmer model is a foreign key on the code model.

How do I achieve this, it’s in Django 🙏.

Spend 1 minute a day to improve your Python skills

I have a youtube channel called ProgrammingWithYash where I publish a short Python tutorial every day. My goal is to teach a common pattern or technique in under 60 seconds.

I try to be respectful of the viewers time and make the videos terse and clear with as little unnecessary fluff as possible. The content is mostly aimed at beginners, I hope it can help some of you to get into the habit of learning something new every day.

As I'm just starting out with this youtube thing, I'd love to hear your feedback regarding the format, content, anything... (topic suggestions are highly appreciated as well).

So I Accidentally Made a (Harmless) Virus...

I was messing around with python (specifically pynput) and got bored, and thought "wouldn't it be cool if I made a virus?" Now, when I thought this, I was doing purely for shits and giggles, and I had/have no harmful intent.

So the virus consists of a basic forever loop, which just takes control of your mouse, and prevents you from moving. Really basic, I know. So I run the file, and to my surprise is works! Except I didn't implement a fail safe, so nothing would work to stop the program. I obviously couldn't use task manager, and Alt + F4 didn't work. So I ended up just turning off my PC lmao. I wanting to see if my computer would detect it as a virus, and it sure did. It didn't delete it, but it did warn me, which is reassuring but also funny.

But yeah I didn't send the code to anyone or anything, just a harmless thing that took me less than 5 minutes.

SQLAlchemy - calculate a default value during instance creation

Hi all,


I'm creating the following table.
I would like to automatically populate the value for createdAt from the period DateTime + a time delta from duration in seconds. (I want to avoid doing this in my PGCRs instantiation).

So this would look like, outside the DB table:

createdAt = period + datetime.timedelta(seconds=duration)


Here is my model for reference:

class PGCRs(SurrogatePK, Model):
"""
A table to store a list of players PGCR's.
PGCR's are linked back to user via 1 to many relationship.
"""

tablename = "pgcrs"
instanceId = Column(db.Integer, nullable=False, default=666)
duration = Column(db.Integer, nullable=False, default=666)
period =

How to embed a simple-prompt ipython?

How ca I pass the --simple-prompt argument in IPython.embed()?

If I add to my code

from IPython import embed ; embed()

This drops me into a standard ipython which causes issues for me, while a simple prompt version would work OK.

Thank you!

Why you should use Django in 2021

Building a backend for a web application is tricky. It involves selecting a language that you are comfortable with and then picking a web framework built on top of that language to avoid writing things from scratch.

There are a ton of web frameworks out there, each designed to address specific needs. The Django web framework addresses all of those needs to a reasonable extent and hence it is preferred by companies like Spotify and Instagram.

## What is Django?

Fun fact: Django was named after the jazz guitarist *Django Reinhardt*.

Django is an open source web framework built on top of python. The primary purpose of Django is to enable super fast development of backend applications. 

A backend application is nothing but an interface to a database meant for reading the data models and presenting it to a user in a form that they understand. It is also responsible for creation of new entries in the database and updating existing data.

Why use a web framework?

If one has to do this from scratch here is what will happen. First you will realise that raw SQL queries would have to be written to manipulate the database and this stops scaling pretty quickly.

You might then resort to

We made a tool to prevent merge conflicts before they even happen - GitHub app + VSCode extension, would love feedback from the Python community

Hi everyone, I’m Kiril and together with my co-founder we are building developer tools we wish existed.

Our og idea was building a new version control system (and we do have it bootstrapped), but now we are making tools that are easier to be plugged into an existing workflow.

We built two tools we heard from other devs might be cool:

​

A plugin for VSCode that detects in real time if your \_local\_ and even \_uncommitted\_ code conflicts with other on your team. Check it out here [http://getsturdy.com/](http://getsturdy.com/)

A Pull Request bot that will write a comment in the PR if it conflicts with other PRs https://getsturdy.com/changelog

The thinking there is by giving early heads up about conflicts, people can make more informed decisions (eg. pull latest code, work on another file, coordinate with colleagues etc.)

The tool installs as a GitHub app and similar to a CI tool it requests access to code to do it’s job (responding to web hooks and continuously making checks).

The VSCode plugin is open source https://github.com/sturdy-dev/sturdy-vscode and we would like to have the backend open source too, as soon as we clean up the code.

I would be super thankful for any feedback the community might
