Help deploying my first project to production.

Hello,

I have a little experience with Django and Ive recently just finished developing my first solo django project. Its an art website for my dad’s paintings that features a home page, gallery, and contact page. I would like to host this website online but I’m not sure of the process to go about getting the project ready for production and deploying it. Ive found plenty online but id really appreciate if any experienced django developer could help me with the process.

Flask-SQLAlchemy, how to render supposedly easy query

Hi all,

I'm using SQLAlchemy in flask using flask-sqlalchemy as mostly suggested around the web but i'm facing some issues on basic queries (maybe it's something wrong on the model).

I have this model:

class Event(db.Model):
id = db.Column(db.Integer, primarykey=True)
timestamp = db.Column(db.DateTime(timezone=True),default=datetime.now(),serverdefault=func.now())
date = db.Column(db.Date(),default=datetime.now(),serverdefault=func.now())
environmentid = db.Column(db.Integer, db.ForeignKey('environment.id'))
sourceid = db.Column(db.Integer, db.ForeignKey('source.id'))
releaseid = db.Column(db.Integer, db.ForeignKey('release.id'))
event = db.Column(db.String(200))

def repr(self) -> str:
return '<Event {}:{}>'.format(self.id, self.event)


First issue is that I supposed that "date" field, using (db.Date()) column, would be a date without a time (e.g.: 2023-04-11) while in my database (sqlite3 in my desktop, shall be mysql once put into "production") is still a timestamp (e.g.: 2023-04-11 09:05:13). I Suppose that on mysql this would be rendered correctly?

Second issue, tied to

Best practise with django migrations in google cloud run.

Hi folks,

I've got a containerised django app in google cloud run. I've began the process of automating its release using github actions and all is going smoothly, but i've hit a bit of an issue that im not sure on the best practise on. When handling migrations, what would be the best way to do this?

I feel like the way to go is to, once i've deployed the new instance to cloud run, to get the CD pipeline to run `./manage.py migrate`, but i can't find much documentation on whether this is okay. I could also add this to the dockerfile, but i dont really want to be trying to migrate every time google spins up a new instance.

Note that im using a database hosted outside of google due to extensions required that google SQL Cloud doesn't support.

Track user interactions

I am writing a django app that has staff and client users, I want to be able to track various actions like "Client X filled out Y form" or "Staff X exported Y document" in a live updated feed on my management page. Is there a django package for something like this? If not I'll make it myself - I'm thinking of using HTMX polling.

Using Python and AI to query and ask question about your audio data

Hey there!

After receiving such a warm response to my last tutorial on extending OpenAI with new knowledge, allowing you to ask it anything your heart desires, I'm excited to share a brand new video on querying your audio data! Check it out here: **https://youtu.be/Klf9aIxh1Lc**

In this video, I tackle a super common use case that I bet many of you have faced. Give it a watch, and let me know if you've experienced the same issue!

I hope you enjoy it and find it helpful. But before you dive in, please keep in mind that you'll be sending your data to an API, so it's best not to use private or sensitive information.

Is anyone working on edge computing solutions targeting Python?

Many companies are now rolling out their WebAssembly based or isolated V8 edge computing serverless function solutions.

E.g.

[Supabase](https://supabase.com/blog/edge-runtime-self-hosted-deno-functions) (news in today)
Cloudflare

Most of these solutions target TypeScript/JavaScript developers. I wonder if anyone is working on edge computing solution that would target Python as the developer language? Either through WebAssembly compiled (widely supported today) or some specific Python isolation method.

Introducing Markdown Code Runner: Automatically execute code blocks in your Markdown files! 🚀

Hey r/Python!

I recently developed a Python package called Markdown Code Runner (markdown-code-runner) that allows you to automatically execute code blocks within a Markdown file, including hidden code blocks, and updates the output in-place. This can be super useful for maintaining Markdown files with embedded code snippets, ensuring that the output displayed is always up-to-date and accurate. It also enables generating content like tables, plots, and other visualizations directly from the code.

GitHub Repository: https://github.com/basnijholt/markdown-code-runner

Key Features:

- Automatically execute code blocks, including hidden code blocks, within a Markdown file
- Allows hidden code blocks to generate content like tables, plots, etc.
- Works with Python and Bash code blocks
- Keeps the output of the code blocks up-to-date
- Easily integrates with GitHub Actions
- No external dependencies and works with Python 3.7+

Why Markdown Code Runner?

When creating Markdown files with code examples, it's essential to keep the output of these code snippets accurate and up-to-date. Manually updating the output can be time-consuming and error-prone, especially when working with large files or multiple collaborators. In addition, there might be cases where hidden code blocks are needed to generate content such as tables, plots, and other visualizations without displaying the code itself in the Markdown file.

New release of FastKafka improves testability

We were searching for something like FastAPI for Kafka-based service we were developing, but couldn’t find anything similar. So we shamelessly made one by reusing beloved paradigms from FastAPI and we shamelessly named it FastKafka. The point was to set the expectations right - you get pretty much what you would expect: function decorators for consumers and producers with type hints specifying Pydantic classes for JSON encoding/decoding, automatic message routing to Kafka brokers and documentation generation.

https://github.com/airtai/fastkafka

The new release adds in-memory Kafka broker that can be used for testing without the need to install Java and start a broker. It allows you to write a simple-to-understand tests such as this one:

from fastkafka.testing import Tester

msg = IrisInputData(
    sepal_length=0.1,
    sepal_width=0.2,
    petal_length=0.3,
    petal_width=0.4,
)

# Start Tester app and create InMemory Kafka broker for testing
async with Tester(kafka_app) as tester:
    # Send IrisInputData message to input_data topic
    await tester.to_input_data(msg)

    # Assert that the kafka_app responded with IrisPrediction in predictions topic
    await tester.awaited_mocks.on_predictions.assert_awaited_with(
        IrisPrediction(species="setosa"), timeout=2
    )

I used Python to make a BizBuySell web scraper to get businesses for sale in a given state. I used aiohttp to fetch requests asynchronously. The code has a rate limiter as well!

Hey friends! Back again with another python web scraping project.

A founder reached out to me to know if it was possible to scrape BizBuySell for businesses for sale in a specific state. They needed the data for business development. I never scraped this site so I was up for a new challenge.

At first I ran into issues with bot blocking. They use Akamai CDN. However, with a bit more research, I managed to get the data. The site was not too difficult compared to others. No dynamic javascript which means no need to use selenium. I only fetched the first 12 pages to keep the demo short. Happy to answer any web scraping questions.

Nested LDAP groups for Flask not working



Hello!

I am currently using flask_appbuilder.security.manager in order to provide LDAP authentication for my Airflow instance(Version 2.5.0) . When doing the AUTH_ROLES_MAPPING
I have noticed that it only works for direct members of the active directory groups I am calling out. Has anyone been able to get this to work for nested groups?

Example:

in my current set up

AUTH_ROLES_MAPPING = {"CN=ADMINACTIVEDIRECTORYGROUP,OU=ResourceAirflow,OU=ResourceGroups,OU=!!sample,DC=sample,DC=sample" : ["admin"]

User A: member of ADMINACTIVEDIRECTORYGROUP
User B: member of ROLEGROUP which is a member of ADMINACTIVEDIRECTORYGROUP

Only User A would be able to login to my airflow instance as Admin since flask is not recognizing nested group membership

I have tried multiple variations of

member:1.2.840.113556.1.4.1941:=

memberof:1.2.840.113556.1.4.1941:=

to no avail.

Thank you for the help or insight if others have gotten nested AD groups working. This would be extremely helpful.
