PyCharm users: Why do you prefer it over VSCode or other editors

After some very spirited arguments from VSCode users, I'd like to turn it around and ask PyCharm users the same thing: why do you use PyCharm and not VSCode or another modern text editor?

Is it deeper integration with language/framework features? Is it the plugin ecosystem? Or the shortcuts?

Disclaimer: I'm a PyCharm Pro user myself. ;-) But I must say, when I do anything outside of Python/Django, I use VSCode 95% of the time. Not that it's that much, but still.

Uploading file on local Storage for Flask on Heroku.

I've build this web app that takes pdf file from user and store it in a folder inside my project. My code is working fine on local server. Whenever I upload file, it gets uploaded in the designated folder but when I host my app on Heroku, I'm not being able to upload file anymore. Could you please help me in figuring it? Thanks.

How to export data from JSON file to database

models.py
class Stock(models.Model):
company = models.CharField()
sector = models.CharField()
per_asset = models.DecimalField()

serializers.py
class StockSerializer(serializers)
class Meta:
fields = '__all__'

views.py
class StockAPI(generics.ListCreateAPI):
queryset = Stock.objects.all
serializer_class = StockSerializer


I scraped down the stock informations for my model, in a dictionary and dumped dictionary to a JSON output file.
This is going to be one time scraping to load the data. But I am not sure what will be the next step going forward, how can I export the data from JSON file to my Stock model database?

Anyone used scipy.optimize?

Trying to get my head around the scipy optimize library and especially minimize function. Part of it is the bewildering assortment of methods like Brent and Krylow methods etc. Are their any good tutorials on using the multivariate versions of these? I am having trouble with the minimization terminating early without deviating far from my initial x0. Any thoughts?

Tutorial: React/SPA with httpOnly Django Sessions instead of JWT Authorization

Hey all, I've created an honestly somewhat-dysfunctional tutorial on how to integrate Django httpOnly cookie sessions with React for the sake of security and avoiding stateless authorization on browsers. I couldn't find any tutorials online that included httpOnly cookies, and honestly the DSF is pretty negative against JWTs (and JS accessible session cookies...). So here's a full breakdown tutorial!

https://github.com/Andrew-Chen-Wang/SPA-with-sessions

The demo is found here: https://acwpython.pythonanywhere.com/authenticated/ When you go to the authenticated URL, you'll find your session cookie and csrftoken set. (You can change the csrftoken to also be httpOnly in the settings). Static is deployed on GitHub pages every time you update the React app and does not delete old static files in case of delays in server deployment.

Please provide feedback! Also look at issue #3 of the repo. I just have haunting memories of working on SimpleJWT (disclaimer, I'm a maintainer) + JWT Authorization integration to becoming httpOnly cookies at PR #157.

Site themes: pitfalls to look out for?

I have a Django e-commerce project I am working on, and while I'm capable of getting the front-end all themed up nice and pretty, I'm looking at simply purchasing a pre-built theme from Themeforest or a similar provider.

Obviously I can't just go find a Wordpress or Shopify theme or something. I assume it should pretty much just be plain HTML+CSS+JS and I will have to modify the markup in their templates to be used with Django's templating syntax, but outside of that, is there anything specific I should avoid?

I've always just built my own front-end stuff but this time I'd like to skip that since I'm in a time crunch and pretty much any typical theme that has the basics will be good enough for me.

Django concurrent users estimate

I want to build an E-learning platform with Django and wanted to know aprox. how many concurrent users can an average Django web app handle right off the bat, with no optimization, since i want to make a pretty agressive marketing strategy and not feel bad about choosing Django. Want to host the app on linode, their 20$/40$ VM.


I know it depends on a lot of factors, but from your own experience?

Live flight sim tracker built in flask

I got fed up with the terrible visual map in Microsoft Flight Simulator.

I wanted a solution that would allow me to load a visual map of my plane location on a separate device - iPad, phone, chromebook, laptop.

So I built an app comprising: a small client which runs on the computer running the flight simulator, which sends flight data to a flask server which then serves up a visual map.

It uses flask, javascript, bootstrap and leaflet.js for the mapping.
