How do you handle dynamic interactions
So I'm building a sass app where my productivity is pretty much my main concern. Since I have extremely limited time server rendered html with Django is my choice. It's going great for me even if I am quite new to the framework.
Problem now is there are a couple cases where I need a bit more interaction. Way back I used to do this with Ruby on Rails with jQuery AJAX where the server returned a small chunk of html that got swapped out on the existing page. I was thinking of doing the same thing again, but I was wondering if anybody has any better solutions or pointers.
I definitely want to minimize JavaScript and absolutely want to avoid adding react and a whole lot of other stuff (state, router, ...) For example. I'm looking for a minimal solution that's quick to develop.
Main use case for me is something like an invoice where the user can add items dynamically. This means some kind of modal pop-up type thing where they can search/filter/sort through items to add the correct one.
Any ideas appreciated!

I cannot even begin to get %load magic to work without an absolute path.
My personal ‘Scripts’ folder is in both my Path and PYTHONPATH environment variables (Windows), and I can even import files in that directory in Jupyter Lab with no problem.
I’m trying to `%load` a file there called `first_cell.py`. I’ve tried all these variations:
%load first_cell.py
%loadpy first_cell.py
%load first_cell
%loadpy first_cell
I get this error (after a big stack trace):
ValueError: 'first_cell' was not found in history, as a file, url, nor in the user namespace.
or:
ValueError: 'first_cell.py' was not found in history, as a file, url, nor in the user namespace.
Putting the complete absolute path (`%load C:\Users\atimh\Scripts\first_cell.py`) *does* work, but it’s a giant pain. It’s not portable, and it defeats the purpose: it should be something easy to remember and quick to type, else why even do it?
I know I can just run the file, but showing all my preferred imports every time communicates far more clearly what’s going on.
And being forced to stick it in some “special” folder hidden away somewhere is not a good solution. I don’t want to be forced to scatter all my Python scripts to the four winds.

Need help with how Django does URL reversing
[https://docs.djangoproject.com/en/2.2/topics/http/urls/#reversing-namespaced-urls](https://docs.djangoproject.com/en/2.2/topics/http/urls/#reversing-namespaced-urls)
With the docs that I have linked, *step 1* seems pretty clear cut.
Take the example of `'polls:index'`:
* *First, Django looks for a matching* [*application namespace*](https://docs.djangoproject.com/en/2.2/topics/http/urls/#term-application-namespace) *(in this example, 'polls'). This will yield a list of instances of that application.*
After that I'm unclear on *step 2*. What exactly would be a current application if there is a list of application instances as stated in *step1*?
* *If there is a current application defined*, Django finds and returns the URL resolver for that instance.

Getting Flask app to work on VPS.
I just got a VPS service to host my flask app on Hostinger.
When I get flask apps running on my local machine, it’s as easy as just doing :
$ python flask_app.py
On my VPS, I can run the same command, but I can’t access the app from outside the server. All instructions online are quite arcane, so I ‘m hoping someone could point me in the right direction!
Context: I used to host my app on Pythonanywhere, but they often have downtimes so I’m forced to look for a more stable option.

Implement Vue into an existing Django (but not djangorest) project?
Hey, I'm still not a very advanced developer, but I was looking into learning a front end framework...with the primary goal of doing some on-the-fly data filtering in a form. Essentially I want to, when a user selects an option from a dropdown, filter another dropdown based on some parameters that are too cumbersome to have loading with the page.
So I figured I need some kind of framework to handle that, and I had a few questions:
1. Is Vue a good option for this, generally speaking?
2. Is there another, simpler way to do this? Have a small section of the page make calls to either a function in my Django project or straight to the database to retrieve some data.
3. If Vue IS a good option, how do I get around the fact that they both use the { } syntax? Am I going to have to rewrite my django templates to not actually include Django?
Any other insights would be great! I want to fully learn Vue or React soon, but thought maybe a simple implementation into a real-world existing project would be a nice way

Burnout & Personal Projects
I've been developing web apps using Django as my main tool for about 4 years now.
It started with needing to solve a problem at an old job (requiring a relatively simple CRUD db app with some vaguely interesting front end stuff) and Django seemed like a great tool. I read tutorials and the Django docs and taught myself the basics over a few weeks, refined and expanded the app, read some more, bought a copy of TwoScoops, asked lots of questions on Stack Overflow and on /r/django (shoutout pydanny), and refined it some more. Had some ideas for personal projects that interested me, learned how to use REST APIs, built a reddit bot, read about ML, put a small portfolio together on github and ended up getting headhunted to be the lead developer at a company with some interesting tech problems to solve and a Django codebase that was in desperate need of some TLC.
Fast forward a few years and professionally things have been great, the money has grown, but so has the responsibility and mental energy required.
I just realised its now been months since I touched a personal project or did any development outside of
