Passing variable within string to TemplateTag?

Is it possible to somehow render a variable within a string when passing it into a template tag?

This is what I would like to do:

{% my_template_tag src="images/brand/{{ image_name }}.jpg alt="{{ image_name }} loading="lazy" %}

Or is the only way to rewrite the template tag to take in `*args` and then do something like this?

{% with src='images/brand/'|add:image_name|add:'.jpg' %}
#tag info here
{% endwith %}

Django-middleware based inventory management database.

Hello. I'm a newbie looking to do a university project. It involves an inventory management database that will have an interactive front end, with simplified functionality. The front end will focus on practicality and not optimization or style, it's there just for the interactivity with the data in my database.

I'll be doing a presentation on my laptop, so hosting the website on localhost is a viable option at this time of the post. I am also thinking of dockerizing the final product.

I'm currently looking into the type of stack I'll need to pull this off. Thus far, I've picked :

-Postgresql for the database

-Nginx for hosting

-Django to connect my database to the front end

-Html, CSS, and vanilla JavaScript for the front end, since I have no experience with JavaScript at all.

I've read I can also use Django's built in local hosting capabilities for my project, so I can skip apache / nginx and another http gateway. The most important thing for me is for the project to be doable and not have an impossible stack of technologies I need to learn in a couple of months. I have experience with python in automation, which is why I picked

Celery Worker, Beat & Redis - Best Practce in Production

Hello everyone,


I recently had an issue with my celery worker and beat, notifications stopped getting sent, I had to rebuild the docker images to get them to work.


The Issue:

After the rebuild, stale notifications started getting sent, including those that had already been sent before


My Question:

Are there recommended best practices for configuring Celery worker, beat and redis to prevent such an issue?

What would you generally recommend in setting up these services?

I used Flask to build this microblogging site in 6 hrs! It keeps your brain sane.

I grew tired of platforms like X and YouTube, noticing how they contribute to the decline of attention spans and critical thinking skills among my friends and others online. Keeping users hooked earn them a profit, not us.

NoHush is something where people don't stay confined within their own echo chambers. This is just a concept prototype, nothing fancy, but it gets the job done. It's UI is very brutalistic.

Special Feature is that you can share a post, and only that post will be shown, no distractions in between.

Discussion Are there specific technical/scientific breakthroughs that have allowed the significant jump in maximum context length across multiple large language models recently?

Latest releases of models such as GPT-4 and Claude have a significant jump in the maximum context length (4/8k -> 128k+). The progress in terms of number of tokens that can be processed by these models sound remarkable in % terms.

What has led to this? Is this something that's happened purely because of increased compute becoming available during training? Are there algorithmic advances that have led to this?

Hiring a Django back-end only dev

I have minimal experience with Django although I am able to recognize core functions due to some experience with Flask. I also have some experience with html/css/vanilla js.

I am have been in talks with a good backend Django developer who has minimal knowledge of FE development. Although I am confident I could develop the solution myself, I do not currently have the skills to develop at the speed that is required to produce an MVP.

However, my doubts stem from this developer's lack of experience with FE work. I thought I could just slap on a pre-built template like Metronic after the back-end views and models are complete but I am realizing this will still require a ton of work to configure, remove unused code, add graphs, tables etc etc. Am I overreacting or would it be smart to just hire another FE developer to assist with this or hire someone who has experience with both Django BE and Django templates?

Ruff 0.4.0 just dropped, with a faster parser and a new language server

Release notes here, seems to be a 20-40% improvement around the board.

This version features a new hand-written parser (rather than a generated one) that is much faster and offers better error messages. It also comes with a new rust-native language server inspired by rust-analyzer, that is multithreaded. I think they’re challenging Pylance’s throne, wouldn’t be surprised if the team goes after type checking next.

Project: An Interactive Python Dashboard For Data Storytelling UN Food Security

Python’s Plotly Dash is a powerful tool for creating interactive data visualizations. As a Comp Sci professor, I use it extensively for interactive dashboards.

Its usefulness lies in its ability to create web-based applications directly from Python code, without the need for additional web development skills.
Using UN food security data, let me show you an example of how you can create an interesting and useful Python Plotly dashboard that tells a data story using:

* **A bubble chart:** with variable-sized markers, a bubble chart can represent the severity of undernourishment within a given country. Each bubble visually represents the scale of undernourishment.
* **A horizontal bar chart:** with its rigid organized structure, a horizontal bar chart provides a clear ordered list that emphasizes the 10 most undernourished countries by percentage of population.
* **A dropdown menu:** by Year, allowing the user to see the changing story over a period of time.

These two data visualizations offer a dual perspective on the global picture of undernourishment: one that is geographically broad and another that is focused and comparative.

***Here's a step-by-step project on how to put this all together.***

I am trying to wrap my head around flask's capabilities. I am looking for live examples of websites using flask mostly by itsself with html/css but without javascript or with hardly any javascript or any other programing languages besides python. Huge bonus points if the code is open source.

Connecting Django to an existing database

Hey, so i want to create a simple web-ui for an existing database. It's a Flask page now but for learning purposes I want to move it to Django and now I'm stuck on 1 little thing. That database. It already exists and has quite a bit of data and no id column (as I know Django creates one). It also gets filled with more data by another program.

I'm not sure where to start with this as it would be very nice if it didn't ruin the existing database..

I don't mind reading documentation but I just don't really know what to look for so some key words or functions or whatever to search for would be very helpful already.

I can't be the only one wanting to do this.
