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.

RepostSleuthBot - Now Public

I've been working on this project for the last 2 years. It has gotten super popular and I've had a ton of requests to open the code up. I was always resistant since I considered it kind of a mess. I decided to take some time to clean it up a bit and make the repo public.

It has a lot going on, but nothing very complicated.

It makes heavy use of Celery for scheduling jobs and runs \~20 Docker containers for the various services.

It's not something you would easily be able to deploy on your own, however, I figured some people might be interested in seeing the workings.

Rock Paper Scissors by a Beginner

Just a little game I programmed to test and improve my skills and I am pretty much satisfied with the end-product.

My first program where input function hasn't been used so no need to press ENTER key and you can play it by pressing "R", "S" and "P" keys.

How to disable "searching..." message in django-autocomplete-light dropdown

Hey everyone,

I've been struggling with something I guess should be simple: I'm using django-autocomplete-light and django-taggit to autocomplete a tag select. The dropdown briefly shows a "searching ..." message at the top of the result list, even when all the results are already there.

I'd like to disable it, but have difficulties figuring out how.

It's possible that I should overwrite a javascript function, but I'm not sure and my javascript knowledge is limited, so debugging is hard. Any pointers would be greatly appreciated.

Thanks!
