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).

I created a webapp to help find new fantasy football team names. Feedback appreciated!

xpost from r/fantasyfootball

In my spare time I build things. I created [Fantasy Name Search (fantasynamesearch.com)](http://fantasynamesearch.com/) to help managers find new team names based on their current roster of players or any other key terms. I wrote everything in Python and used the pool of Yahoo's 2019 public leagues as source data for all 500,000 team names. I hope you find it somewhat useful in finding a new team name, if not just for fun to find the most outrageous team names. Let me know what you think!

For those more programmatically literate, I wrote an article describing the guts of the project and process in a little more detail: [https://medium.com/swlh/in-search-of-a-fantasy-football-name-5656e8af5944](https://medium.com/swlh/in-search-of-a-fantasy-football-name-5656e8af5944)

[N] Microsoft teams up with OpenAI to exclusively license GPT-3 language model

"""OpenAI will continue to offer GPT-3 and other powerful models via its own Azure-hosted API, launched in June. While we’ll be hard at work utilizing the capabilities of GPT-3 in our own products, services and experiences to benefit our customers, we’ll also continue to work with OpenAI to keep looking forward: leveraging and democratizing the power of their cutting-edge AI research as they continue on their mission to build safe artificial general intelligence."""

Should I split my API and Worker?

I have a flask api that currently puts jobs on rq queues to be processed. The api and the "processing engine" is all part of the same flask code base and I launch it all together in a single docker container (with docker-compose). Let's say I have this app deployed on an EC2.

I am confused on how to scale this when there is a bottleneck on jobs and not the API. If I scale the EC2 instances directly, I'll have multiple APIs running, but the bottleneck is in the queues.

So should I instead split my API and Queues into separate docker instances? And then deploy each of those on separate servers? That way I can load balance the queue servers separately but the API can still run on a single instance.

Just want to make sure I am thinking about this correctly.

New easy to use JWT token based Authentication for Flask Apps

​

​

[Flask JWT Router](https://preview.redd.it/kljqppppiro51.png?width=4113&format=png&auto=webp&s=bb193e7ff953351f4267807cae44f530aa8c2ed1)

Please try out a new token based Authentication library for flask. Great for apps that provide data for Single Page apps (React, Angular, Vue.js etc.)

[https://github.com/joegasewicz/flask-jwt-router](https://github.com/joegasewicz/flask-jwt-router)

It directly hooks up to Flask-SqlAlchemy, so your logged in user is accessible on Flask's global context object (Please see the docs)

Solution for allowing API access from external apps?

Hello!


I have a django webapp and wanted to hear some suggestions for api access for external applications. I would like to allow users to be able to make protected API calls into my platform with best security practices.

What I had in mind was giving a token for external platforms and setting up an API urls route for all the calls that they may need. But that is about the most I can think of. Any one with a system with great suggestions?

[D] Snapchat Anime Filter

If you don't know what I'm talking about, take a look [here](https://comicbook.com/anime/news/snapchat-anime-filter-viral-manga-2020/#10).

As soon as I saw how stable the generation of the filter was, I started experimenting with it and trying to figure out how they did it.

My current belief is as follows. They manually hooked up the features from their face detection/recognition algo into an anime face GAN. So you can think of as those sliders that control age/hair colour/skin colour on the face generation website but hooked up to features from facial recognition.

SC definitely has singled out which algo features correspond to which facial features because they use hair colour/length in other filters.

This approach leads to the more generic anime faces seen in the filter, but is way more stable than something like https://selfie2anime.com/ that does image-to-image conversion.

Aside from that, the filter just does a simple posterisation and overlays the face in the right spot.

Thoughts?

Implementing social authentication for Django web application??

Hello everyone, I can't for the life of me figure this out.

I am creating a web application that will use private Yahoo! API's.

From this, I would like to have a log in button for Yahoo!, that will authenticate the user using Yahoo! OAuth2. Once authenticated, I want to retrieve the access_token so that I can make API requests for the given user...

I have exhausted many pages of google tutorials, I can't figure this out...

This website here does exactly what I want to do: https://yfantasysandbox.herokuapp.com/

Where the user simply logs in through Yahoo! and I can store their token to make future API requests...

Can anyone point me in the right direction regarding this???

Need help to find ways to generate reports

I'm building an app using Django. In this app, I would like to generate pdf reports using weasyprint package.

In my app, I have views to get data from my models and process this data (I do this by calling functions that I wrote in a separate module) then pass it to the templates to display it.

In these templates, I have a button to download the pdf report, when clicking this button it will redo (re-call functions from the module) which some functions take time (in case of year report) to return the result.

I would like to know if there are other ways to generate the report without recalling these functions?

And how about sending the result data from templates using AJAX to the view that generates the pdf report? This is a right way? There are other ways?

Below views that I use to display the day and last year stats (the first and second one) and to generate pdf (the third).

def day_period_stats(request, period):
day = timezone.now() if period == 'today' else timezone.now().date() - timedelta(1)
result = get_tasks_info_of_day(day)
return render(request,
