Tkinter looks notoriously ugly, but did you know that you can make it look just as fancy and modern as Windows 11?

I'm pleased to announce that today I've released a new version of my gorgeous Sun Valley theme, with which you can make your Tkinter/ttk application look like Windows 11.

Clarification on DRF Serializers

I'm still not a 100% on how serializers work. I get that they're used for serializing and de-serializing but WHY are they used for creating and updating models too?! Doesn't this break the Single Responsibility Principle? Anyway, my questions are:

​

1. When we "exclude" a field what does it actually mean?
1. Is it not serialized and de-serialized only or does it mean that it won't be saved when we call serializer.save()? The reason why I ask this is because this field is something I need to be setting in the backend python code instead of being passed in from the user.
2. Does read-only field mean they are passed back to clients but not required when getting data from clients / in api calls?

Templating for HTMX out-of-band swaps

I'm trying out HTMX in a new project, and really enjoying it so far. One thing I'm struggling with though is how HTMX handles updating content in other areas of the page.

With the hx-swap-oob attribute, the default behaviour is to include the other updated areas of the page in the same template partial.

The problem this leads to is having multiple copies of the same snippet, or different snippets returned than the original partial being displayed.

I'm aware of the approach of using django-render-block as shown in the recent BugBytes video. Does anyone else have another approach they prefer for out-of-band swaps?

Thanks!

Pergunta: alguém conhece um Framework CSS para impressão?

Eu tenho gerado alguns relatórios com R e com Python em pdf. Para isso estou usando LaTeX, mas tem sido bastante difícil fazer algumas coisas nele.
Uma alternativa seria gerar em html e converter para pdf.
Então eu procuro um Framework CSS focado em impressão.
Não é necessário ter suporte a paginação ou features avançadas, só uma tipografia já seria o bastante.

Optimization of the Django count() query.

Hey!
Anyone can help me on the django count query thing.


for large databases, the count query takes so much time, leading to the user's waiting.
total_count = catalog_items.count()
Like this query is alone taking 8858ms.


Does anyone help me to optimize this query in the database or at any level?
It will be a great help.

Recruiter asking how much experience is development vs. scripting

Most of my python experience is in scripting and automation, about 5+ years. I am self taught, on the job learner. I have a recruiter asking me to clarify how much of my experience is in pure development.

I have about a year working on a django app, which I guess that would qualify. I assume they would want to grill me on concepts in the interview I might not know well. Such as data structures/algorithms/etc. Or maybe solve a problem on the spot.

I do study some off the clock. If I do get an interview, what would be the best way to prep?

Best Practice for multi-framework project

Say there's a project with the following schema ->

|-backend (Django)
|-frontend (React)
|-external (custom data mining scripts in python)

Some of the rules I set for the project were:
- external mines relevant data from the internet and feeds them into my local postgresql db
- All creation and altering of DB schema would be done through Django (backend)
- external sanitizes the data; backend sorts, analyzes etc data
- DRF is used to send data from backend to frontend

It's come to the point where I really want to start utilizing some Django functionality (models) in my external package.

I was going to research exactly all I'd have to do to simply use python import functionality to bring the models into the module and then it hit me that I could also use the DRF API in external where external could C, U and D the data and frontend could only R it

In some of you folks' experience what is the best way to do this? Import the models or use the API?

Near-Earth Objects - Project Part 7: The Opposition Effect

Hey Pythonistas,

video #7 of my space science related Project "Near-Earth Objects" is out! Last time, I showed you how one can compute the brightness of an asteroid using an empirically derived formula called the "H-G-function". This time I want to show you some strange behaviour of these stony worlds: The Opposition Effect.

What's that?

Well, the brightness of asteroids depends on miscellaneous parameters and geometric considerations, like e.g., the distance between the Sun and the asteroid, as well as the asteroid and the observer (us, the Earth). Additionally, the phase angle between the asteroid - Sun - Earth must be taken into account, too!

For example, a phase angle of 0 degrees corresponds to an imaginary straight line, where the Sun - Earth and asteroid lay on it.

For very small phase angles, the brightness of asteroids "surges" exponentially, but only for a veeery short time: The Opposition Effect.

And in this tutorial I'd like to show you this effect using the corresponding equations.
