Personal offline kanban workflow

Hi all,

I realized that most of the kanban software on the market doesn't have an offline option and can't be exported. So I built my own: xBan

Here's a quick demo of it.

Any advice would be appreciated. Thank you!

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).
