How to code it is so that section 1 automatically links to discussion a. I'm using topic 1,2,3 to organize the discussions and the {%for post in page.get_parent%} in the template to make a navigation system. I want section 1 to always link to discussion a.

Best way to load initial data and maintain it in production ?

We develop surveys for regulatory purposes and we expose them via an API (DRF).

Each survey has questions and we'll have different set of questions for each of our client (wording and number of questions can vary).

We are going live soon, and we haven't settled yet on how to initially load thatdata and how to maintain it (ie. wording may change over time, new question can be added, etc...).

Here's our feeling so far:

Fixtures: We use them extensively in our unit tests and our test environments but it doesn't feel right for production for several reasons:
No tracking of what has been run or what has not yet been run
Force us to deal with PKs
One fixtures can easily be forgotten
Migrations with raw SQL: idea would be to have a folder for each client with the different scripts to be run
Harder to generate and maintain (no loaddata / dumpdata)

What's your take on this ?

Thanks

Aggregate posts from your Mastodon timeline (built with Django)

Hey all, I built https://fediview.com/ with Django. It surfaces posts from your Mastodon timeline with a very simple algorithm -- super useful to just "catch up" on posts you might have missed.

Hopefully it's useful if anyone is on Mastodon. I'd love to hear any feedback!

How long will data be stored in RAM?

Since I use notebook as a demo for images and plots when I do data analysis, I often have my jupyternotebook on and leave it on for weeks incase I need to use/check certain notebooks ocassionally.

​

In the jupyter notebook, there are often multiple cells, and there are some variables being stored and pass to the next cell. And my question is that, how long will the intermediate data be kept, and can I run the cell even after weeks and trust the output as long as there is no error reported?

​

My guess is that if the RAM throws away certain groups of data, then I should not be able to run the cell since the intermediate data it needs is no longer available, which means, as long as it can run, the data is still there.

Also, I am using m1 Macbook, which I know will use the hard drive as RAM in certain cases, not sure if this means the intermediate data will be kept on some temporary files on the hard drive, which sounds to be a safer place to store.

Parsing and validating pyproject.toml files with msgspec

The upcoming release of msgspec
(my fast & friendly
serialization library) adds builtin support for YAML & TOML formats, on top of
the existing JSON & msgpack support.

To demonstrate this, I wrote up a quick example of parsing and validating
pyproject.toml files using msgspec:

https://jcristharif.com/msgspec/examples/pyproject-toml.html

It applies the following standard msgspec workflow to the pyproject.toml file
format:

1. Define a schema using standard python type annotations. If you're already a
dataclasses/attrs/pydantic user this should feel pretty familiar. msgspec
supports a wide selection of common stdlib
types. Any
additional needed types can also be added via an extension mechanism.

2. Pass that schema to one of the supported decode functions (here we're
using msgspec.toml.decode). The decoder will parse and validate that the
input data matches the schema. If it's valid the specified type is returned,
otherwise a user-friendly error message is raised detailing where the data
is malformed.


The same technique can be applied for any of the formats msgspec supports,
allowing msgspec to be a one-stop-shop for serialization & validation in
Python.

Note that unlike the existing JSON & msgpack support, these new formats rely on
external parser libraries (msgspec includes a fast, custom JSON parser). This
has a

# Improvements:

Here are some of the notable improvements we implemented. Along with these were many bug fixes to get Pynecone more stable. 

Components/Features:

🪟 Added Windows support! 
📈 Added built-in graphing libraries using Victory.
Added Dynamic Routes. 

Performance:

⚡️Switched to WebSockets (No more new requests for every event!)
Compiler improvements to speed up event processing.

Community:

⭐️ Grown from \~30 to \~2400 Github stars.
70 [Discord](https://discord.gg/T5WSbC2YtQ) members.
13 More contributors.

Testing:

✅ Improved unit test coverage and added integration tests for all PRs.

Next Steps:

Add components such as upload and date picker.
Show how to make your own Pynecone 3rd party libraries.
And many more features!

Add Watermarks To PDF, JPG & PNG files with no restrictive licensing

I created a small Python package to add watermarks to PDF, JPG & PNG files.

**Why?** Most Python PDF packages have licensing that requires you to release your source code which isn't ideal for everyone. In this package, I've utilised PIL (open source HPND License) & Pypdfium2 ( either Apache-2.0 or BSD-3-Clause, at your choice. ) and the code itself is released under MIT license.


Check it out - [https://github.com/bowespublishing/pythonwatermark](https://github.com/bowespublishing/pythonwatermark)
It can probably be massively improved but it works :)

## Installation

Installing the latest PyPI release (recommended)

python3 -m pip install -U pythonwatermark

This will use a pre-built wheel package, the easiest way of installing pythonwatermark.

## Dependencies

pythonwatermark uses two awesome open source python packages to work it's magic they are...

Pillow - [https://github.com/python-pillow/Pillow](https://github.com/python-pillow/Pillow)

Like PIL, Pillow is licensed under the open source HPND License

Pypdfium2 - [https://github.com/pypdfium2-team/pypdfium2](https://github.com/pypdfium2-team/pypdfium2)

PDFium and pypdfium2 are available by the terms and conditions of either Apache-2.0 or BSD-3-Clause, at your choice.

These are both fantastic packages and are liberally licensed meaning unlike with other options you don't need to release your source code to the public.

## Usage

Import watermark utils

from pythonwatermark import watermarkutils

Add watermark to file

watermarkutils.put_watermark(inputfile, outputfile, watermark,

Am I over thinking this question?

Just for some context, this is my first coding class and read what I am supposed to read in the text book. All it taught us was how to use print and how to set up basic math.

This is the first question on the homework, this question seems complex for the first question. How am I supposed to know how to set this up with knowing little to no nothing about coding?

Message Queueing: Using Postgres Triggers, Listen and Notify as a replacement for Celery and Signals

A common pattern in modern web development is the requirement to process data asynchronously after some user action or database event. In the article below, we describe via a concrete example a traditional approach to solving this problem for a Django/Postgres based application using django signals and Celery. We then proceed to discuss some of the shortcomings of this approach and demonstrate how using PostgreSQL triggers alongside the PostgreSQL LISTEN/NOTIFY protocol can offer a more robust solution.

Skinny models and fat views? Where should I be writing this code?

Hey folks,

I'm writing an app using Django that has fairly minimal locally stored data and is heavily dependent on hitting an external API for data, taking the returned data, manipulating it and mixing it up with locally stored object, before sending it back to the API.

I'm doing a lot of the work in my views.py file, even though what gets rendered to the client side is nearly irrelevant to the project ("here's a sign up form", "you've signed up for X" or "success, you've unsubscribed from y")

So that, combined with there being a) not a ton of local objects being used and b) a lot of taking external data and manipulating it for my needs means I'm getting relatively large views -- more logic happening there than in my models, for sure.

So I'm wondering if there's an inherent problem with writing 'skinny models, fat views' in a case like this? Or if convention or something suggests I should pull some/much of my code into a separate file (a utils.py or bad_architecture.py or whatever) file and just import at runtime? Is there any reason I should be doing that besides DRY when/if that becomes an issue?

Hopefully that makes sense
