Django multiple forms as popups and AJAX!!!

In my project I have a page where all the multiple user types are listed as cards and I was trying to add a detail view to each card with update and delete options within the card detail display. So this basically calls for AJAX calls. But I can't seem to figure out how to nest views within templates and style each forms according to my needs. Any advice?

Needed python packages and versions of jupyter notebook

I want to retrieve all the pip packages and versions what is needed in a specific jupyter notebook so I know what packages are required to execute the notebook without errors.

Is there such a library or one liner to achieve this.

The problem with "pip freeze" is that it will show all installed packages what is more than needed for a minimalistic environment.

[D] Deconstructing the GPT-3 economy

As we all know, OpenAI plans to commercialize GPT-3 come October. But will the massive language model actually become a profitable language model?

I had a deep dive into the costs of developing, running, and maintaining GPT-3. There's a lot we don't know about the process and the possible deals between OpenAI and Microsoft that might have cut down the costs.

Here's my take, based on what we do know. I would be glad to have your opinion on it:

[https://bdtechtalks.com/2020/09/21/gpt-3-economy-business-model/](https://bdtechtalks.com/2020/09/21/gpt-3-economy-business-model/)

Key points:

* The costs of developing GPT-3 are in the eight-figures ($10M+)
* The costs of running GPT-3 are in the five-figures ($10K+/month)
* There are costs for staffing, support, legal, ethics, privacy, security, etc
* Model decay will probably require retraining or fine-tuning every once in a while ($1M+/year?)

If it works, it could be huge, a new application development platform that could be as huge as the cloud maybe. If it doesn't, it will be a great woe for the OpenAI team, who are under intense pressure to turn in profits to secure the next round of funding.

Weird Requests from Foreign IPs; Should I be worried?

Hello! Thanks for reading and any help is appreciated!

Background:
I created my first web API, and I feel so empowered! My router has a DNS service, and I am able to obtain a free sub domain via the brand company of the router, so I spun up the Flask development server via Python and port forwarded outside requests to my PC via the router.

I have only shared the URL with family and friends, but I noticed foreign IPs sending odd requests after reviewing the the first day’s log. Some attempt Linux shell commands and one even attempted to post a .cgi file, but they all received 404 responses or HTTPStatus.BAD_REQUEST, so I assume whatever they were trying had failed.

Questions:
- How worried should I be about these odd requests?
- If my server is returning 404 to these requests, am I then protected from these hacks?
- Related to the above question, does the Flask werkzeug or a WSGI server provide the benefit of trapping bad requests? It seems like if my site was just a index.html file, some of these Linux shell commands would get executed on my server.
- Is there a resource of best practices I can read to

How does secret_key help?

This isn't the flask subreddit but I thought I could get some help here. In flask, you are forced to have a secret\_key to prevent cookie manipulation and session hijacking. I don't understand how does the secret\_key help and work under the hood, to prevent such breaches.

Not sure if my Django virtual environment is set up correctly.

I've set up a Django virtual environment. And when I start it by running:

>workon my\_django\_environment

The prompt then displays as follows:

>(my\_django\_environment) pi@raspberrypi:\~ $

Is this correct? Should the pi@raspberrypi:\~ still be there?

If I do this:

>(my\_django\_environment) pi@raspberrypi:\~ $ ls

Then it lists everything in my actual non virtual environment Home folder. But when following guides for setting this up - when they use ls it only shows the files in the virtual environment folder?

I'm confused...

django best way to manage CRUD

I am performing a way to Delete/update/get in a same view like

​

class APICRUDVIEW(APIView):

def get(self,request,id):

....



def put(self,request,id):

....

​

def delete(self,request,id):

....



​

​

So that thing doesn't violate \`SRP\` (Single Responsibility Principle ). Like according to that a class strictly should perform a single task. Or its best way to include all these in a class in django ?

I need an IDE for Django that supports SSH.

I have a dev server, on which I intend to learn Django/Python. I would use VSCodium but it looks like the Python extension has the telemetry which I use VSCodium to avoid. And when it comes to PyCharm the community version doesn't support SSH...

Any recommendations?

Three alternative ways of deploying Django

These are the notes from my talk at DjangoCon EU last week:

[https://gist.github.com/tomdyson/025be30855262287ae048bf4371d26f8](https://gist.github.com/tomdyson/025be30855262287ae048bf4371d26f8)

In 30 minutes I built a very simple Wagtail site and deployed it three times: on Dokku, Netlify and Google Cloud Run. Hopefully the instructions are enough for others to recreate the steps. Some caveats:

* although this demo uses Wagtail, any Django app with a working Dockerfile should work in the same way
* the steps are designed for a quick, impressive demo, and are not intended as best practice reference :)
* in particular, the Cloud Run steps are not complete - pushing a Docker-enabled app is really easy, but database connections and shell access (e.g. for running management commands) is annoyingly fiddly.

I believe the DjangoCon EU organisers will release talk videos in the next few weeks, but in the meantime here are the [slides from the talk](https://docs.google.com/presentation/d/e/2PACX-1vTP9sof4pZO6E9f6gnAVyrP0OW7y42npYdNCWYDMv2NmYivMXCvLdaO8y4eMBDdOh2otgrT-IqmfgNH/pub?start=false&loop=false&delayms=3000#slide=id.g98cee58a9e_0_41).
