jinja IF statements not working for me
Hello
once again i must turn to the best community i know :D
​
I am trying to have a status bar for my website, where it changes color and text depending on the status message that was posted.
I am doing a FOR loop to check for messages, then i use IF statements to check for type of message.
When a condition is met i change the text varible for the Div element and use <style></style> to set the background-color.
​
but right now it shows the color of critical(red) but the text for no issues detected ("Ingen problemer")
what am i doing wrong ? maybe you guys can help me out.
​
{% for post in posts %}
{% if post.pstatus=='Kritisk' %}
{% set ptext='Kritisk' %}
<style>
.statusDiv {
background-color: red;
}
</style>
{% elif post.pstatus=='Advarsel' %}
{% set ptext='Advarsel' %}
<style>
.statusDiv {
background-color: yellow;
}
</style>
{% else %}
{% set ptext='Ingen problemer' %}
<style>
.statusDiv {
background-color: green;
}
</style>
<div class="container-md statusDiv">

Best Practice for Duplicate Application with Different Routing?
The post title is probably confusing but I will try my best to explain what I am looking for...
Currently, we have a Flask application that is hosted on AWS with a domain name (I will call it foo.bar.edu as my example). It is basically an organization registration system, which sends its data to a Google Sheet. My mentor wants to present and demo this software to other companies. As a result, he wants foo.bar.edu/membership and foo.bar.edu/demo as separate instances. The /membership route will be for organizational use, and the /demo route will be for presentations. They will have the same backend logic, but the main difference is that the /demo version will have different frontend and point to a different Google Sheet.
I could think of different ways for doing this, but I wanted to ask what is the best practice. Should I just be copy pasting the blueprints then changing route names? Should I be running them on separate ports? Running two separate Flask instances multithreaded?
This part also hurts my head to think about, but if someone could answer then that would be great... with Flask-admin, how would I be able to achieve foo.bar.edu/membership/admin and foo.bar.edu/demo/admin? I know I could

Make table break across pages in PDF
How do I make a table start immediately instead of on a new page when I print the HTML as PDF. (The HTML>PDF is less strict about starting on new pages than direct>PDF but I would like it to never start on new pages.)

Is there a way to cross-reference a pandas dataframe output on Jupyter Notebook?
I was reading this section:https://jupyterbook.org/en/stable/content/references.html#reference-tables
I want to create automatic references/indexes for some printed pandas df but I don't want to paste the text in the cell to use the {table} chunk. Is there a way I can directly reference the output of some Python code?
EDIT: I can't render/reproduce the glue examples from this page: https://jupyterbook.org/en/stable/content/executable/output-insert.html#the-glue-figure-directive

Is OOP required before learning Django?
I want to create a web app with a minamalistic design. I understand I’ll need to know HTML / CSS. On the backend, from what I’ve researched, I’ll need to know Django.
How much OOP knowledge is required before learning Django? I’m assuming I’ll have to learn OOP, then learn Django if I want to be able to create my web app, correct?

Show text after post was made.
So, I don't want to use messages. I want to show a <p> html tag after a request.
​
I'm trying to do so like this
return render(request, 'index.html', {"form": form, "buttondisabled": buttondisabled,
"songinformation": songinformation.songinformation})
with song\information.song_information being the element I'm trying to pass in as text.
​
{% if songinformation %}
<p>{{songinformation.songname}} </p>
{% else %}
<p>Song information...</p>
{% endif %}
However, once it's refreshed the text set through song\information is reseted with the page. Is there a way to set text once a post request is called?

How to exporte notebook (.ipynb) from jupyter to PDF?
I’m m trying to export a (.ipynb) file to a pdf in jupyter and the steps are: File-> Download as -> PDF via LaTex (.pdf) but when I do this appears this error: nbconvert failed: xelatex not found on PATH, if you have not installed xelatex you may need to do so. Find further instructions at https://nbconvert.readthedocs.io/en/latest/install.html#installing-tex.
I use a macOS and I already installed the MacTeX (I’ve only installed it, I’m not sure if I need to do anything else) and it keeps giving me the same error.
Thanks in advance!

In Matplotlib, is it possible to specify positional x,y coords for text on a plot (not relatively to axes)
ax.text(x, y, "My Text", fontsize=10, ha='left', va='top') <-- x, y here refer positions on the data axes and so will be different for each plot.
​
Is there a way to generically say "top left". ha, va seem to be ignored.
Cheers!

Creating Dynamic URLs from Form Submission.
Hello guys,
I've tried for too long, creating dynamic urls, that are supposed to be extra simple - yet I've been trying for days now and nothing changed.
TL;DR - A user accessed the Form template on ('hunting'), inserted details inside the form, when pressing "Submit" he will be redirected towards "localhost:80/hunting/<int:pk>"
Longer version:
Views.py:
class Hunting(LoginRequiredMixin, View):
contextobjectname = 'huntlist'
def get(self, request):
form = HuntForm()
randomid = random.randint(1,100)
obj = HuntingModel.objects.get(id=randomid)
print('Access Hunting')
return render(request, 'home/hunting.html', {'form': form})
def post(self, request):
model = HuntingModel
randomid = random.randint(1, 100)
obj = HuntingModel.objects.get(id)
form = HuntForm(request.POST, request.FILES)
name = request.POST'name'
limit = request.POST'limit'
os = request.POST.getlist('os')

High performance profiling for Python 3.11
I am delighted to announce the 3.4 release of Austin. If you haven't heard of Austin before, it is an open-source frame stack sampler for CPython, distributed under the GPLv3 license. It can be used to obtain statistical profiling data out of a running Python application without a single line of instrumentation. This means that you can start profiling a Python application straight away, even while it's running in a production environment, with minimal impact on performance.
https://github.com/P403n1x87/austin
The Austin VS Code extension provides a smooth interactive profiling experience, with interactive flame graphs straight into the text editor to allow you to quickly jump to the source code with a simple click. You can find the extension on the Visual Studio Marketplace and install it directly from VS Code:
https://marketplace.visualstudio.com/items?itemName=p403n1x87.austin-vscode
To see how to make the best of Austin with VS Code to find and fix performance issues, check out this blog post, which shows you the editor extension in action on a real Python project:
https://p403n1x87.github.io/how-to-bust-python-performance-issues.html
This latest release builds on top of the significant performance improvements introduced in the 3.3 release. Benchmarking figures (see https://github.com/P403n1x87/austin/pull/126#issuecomment-1279765640 for some of the numbers) show that Austin 3.4 continues to provide a high sample rate at low sampling

Looking at Django for future work
Hi! I've been looking at jumping into the world of Python and Django for some personal projects and (hopefully) use it for doing some freelance/side projects. I work a full time job as a developer and this would be separate from my 9-5. I've worked as a developer / IT generalist for 20+years but never thought to look at python. I've done a bunch of Ruby on Rails and Grails over the years and I expect Django is in the same ballpark. As far as learning it I dont think that will be an issue - I enjoy digging into something new (for me)! As far as future freelance-type opportunities go do you think Django is a good choice nowadays?

Hi Django developers friend, my name is Brandon a Django developer too, I just finished working on djangojob.com and now I'm looking for my next project to work on, but this time instead of building the first idea that comes to my mind and jumping into the code right away, I would like to start asking the community what is the biggest challenge you face as a Django developer every day?

OKTA SSO for Django
Hi, has anyone here configured an sso for django backend using Okta?
I have a django backend and a flutter frontend and am trying to set up a sso for it on Okta. I am having trouble understanding how to connect my django auth system with Okta. I have a lot of permission based APIs so in order to maintain that with flutter I need to set up some sort of auth between my django backend and flutter frontend. I would really appreciate it if someone could point me towards helpful resources or if I could talk to some one who has already worked on it. Thanks!

Prettier for Django templates
Really started loving Prettier to auto-format HTML / JavaScript on save in PyCharm. However it doesn't seem to play nice with the Django templating language – curious what everyone else is using to auto-format their Django templates on save.
tl;dr: What to use instead of Prettier with Django templates?

Machine Learning with Django
Hi All!
Today I updated my website with a tutorial on how to deploy Machine Learning models with Django (DRF), and I would like to share it with you.
This tutorial covers the basics which should be enough to build your ML system:
- can handle many API endpoints,
- each API endpoint can have several ML algorithms with different versions,
- ML code and artifacts (files with ML parameters) are stored in the code repository (git),
- supports fast deployments and continuous integration (tests for both: server and ML code),
- supports monitoring and algorithm diagnostic (support A/B tests),
- is scalable (deployed with containers),
