Starlite development updates January ’23

Hello there fellow Pythonistas, do you have a moment to talk about the web framework of choice, Starlite?

In case you're wondering what the heck a Starlite is, here's a quick elevator pitch: Starlite is an ASGI web framework focused on building highly performant APIs quickly and with ease by providing many tools out of the box such as a stellar OpenAPI integration, ORM integration with SQLAlchemy, Piccolo and Tortoise ORM, type safety using rigorous typing, excellent Pydantic support, and many mechanism for customization.

## So what's new?

The first thing I want to highlight was a much requested feature: Starlite now includes a CLI, allowing to quickly run and inspect Starlite applications, featuring a smart autodiscovery that's not restricted by naming conventions.

The CLI is something we are planning to expand on, u/Goldziher for example is currently working on an TypeScript generator that can generate typing files directly from a Starlite app, using the OpenAPI schema!

In other news, Starlite has succumbed to carcinization; Our query string parsing is now done by a dedicated Rust library. Why? Performance.

As you can see, in this benchmark Starlite handily beats even blakchseep, a notoriously fast ASGI framework written in Cython

What Django admin theme do you use ?

We happily use Django in our company and the plan is that our Key Account Managers will be responsible to manage their customer accounts.

But the feedback I get a lot is that Django admin is scary.

It looks complex with its small button and old school look.

So I want to theme it to make it less scary.

I really like Jolie as a theme, but looking at their website, it looks dead to me. They are asking for 200$ for a beta licence, alongside a button to get notified when it gets live. And I think it's been like this for a year.

So what have you guys implemented to make Django admin less scary for non tech administrators ?

Thanks a lot.

Django authentication works locally but not in PaaS cloud server

I have deployed a Django/Django Rest Framework application to Render and it works well except for the authentication process. I am using PostgreSQL for the database.

​

Authentication is based on Django sessions, and it works in my local server but not in Render, where it returns a 500 server error when trying to log in with some user credentials.

All the other database interactions and APIs work in Render, including registering users in the database. I guess there is some server configuration problem.

​

Any idea about how to solve this?

Render **context as HTML in render_template?

Hello everyone! I'm in the early stages of developing a flashcard solution using Flask. The objective is to have users input HTML for both sides of their flashcards, which will then be rendered when reviewing cards. As a foundation, I have been attempting to develop a simple Flask application that takes an input and parrots it back, rendered as HTML.

I have encountered an issue in that when I return e.g. `flask.render_template("index.html", front="<h1>Hello World</h1>")` on a GET request, `front` here is shown as pure text (escaping tags) as opposed to being rendered as HTML. In other words, instead of a large "Hello World", it displays "<h1>Hello World</h1>".

Example code follows:

# main.py

import flask

app = flask.Flask(__name__)


@app.route("/", methods=["GET", "POST"])
def index():
if flask.request.method == "POST":
return flask.render_template("index.html", front=flask.request.form["front"])

return flask.render_template("index.html", front="Enter something!")

Hello all, i am a python beginner trying to make a portfolio website using flask to show some visualization i created using power bi .

The place "VAR" is originally coded as 0 in the MSFT example it make the page only show the first report i have in the list of report id .

I need to assign a value for var (like 0 , 1,2 ,3 for 1st 2nd , 3rd , 4th report) for different "section tag" to extract the corresponding report but i don't know how .

Thank you

`{% extends "template.html" %}{% block title %}mypage{% endblock %}{% block content %}<section id="report-container" class="embed-container col-lg-offset-4 col-lg-7 col-md-offset-5 col-md-7 col-sm-offset-5 col-sm-7 mt-5"></section>{% endblock %}`

Is it good way to send request whenever model update?

I have to post model data to some websites whenever specific columns of models changed.


1) write request function as override model update function.

2) add a function and use it in the view class.


If I apply 1), I don't need to check when I should add a new function to send requests or not. It'll work well whenever the model changes in every function. But It seems pretty dangerous..

2) I should write the code if I add a new function to handle the model. So if I miss writing the function, that'll not send a post request.

which is the better way..? Should I make a function to send a request? or override the update function in the model?

Best resources to learn Django

Hi,
in the past I only used Flask and I like it a lot. But I thought I will try Django too because it might get me to working applications faster.

What are some good resources to learn the newest Django version?

Most of the stuff I found isn't up to date and maybe you got some recommendations for me.

Run Celery tasks on Railway

I deployed a Django project in Railway, and it uses Celery and Redis to perform an scheduled task. The project is successfully online, but the Celery tasks are not performed.

If I execute the Celery worker from my computer's terminal using the Railway CLI, the tasks are performed as expected, and the results are saved in the Railway's PostgreSQL, and thus those results are displayed in the on-line site. Also, the redis server used is also the one from Railway.

However, Celery is operating in 'local'. I need the Celery tasks to be performed without my pc's terminal doing it. This is the log showing the Celery is running local, and the Redis server is the one up in Railway:
