Use AWS Elasticache Redis as Celery Broker?
So we're using AWS to deploy our project, and using Celery for Event Driven Architecture, so celery workers are always up and running.
We wanted to use Redis as a broker, since SQS has no monitoring support from either Celery or Celery Flower. We tried using AWS MemoryDB Redis as broker, but were unsuccessful as Celery at the moment does not support clustered Redis architecture. So now we're using Elasticache Redis as the broker, but the AWS docs says that Elasticache is not persistent, and data loss might occur if the primary node fails, which means that some messages might be lost which would be really hard to recover.
So my question is that is Elasticache is a wise choice for using Redis as a broker, or we should look at something else?
Also, if someone here has used Elasticache Redis as their celery broker, please let me know your experience and if you would recommend it.

Rendering child templates with context
I am using class based views and my problem is that I have a base template for cards, which provides the styling and functionality for them. I also have multiple card view classes (Card1, Card2, etc) which each have context, and set the template_name to the base template for the cards. I want to be able to call each card class inside my home template, instead of using {% include BaseCardTemplate with..... %} because there is a lot of context. Is there a standard Django way to do this?
​
And if there is a standard way to do this in Django is it also applicable including templates that rely on models? For example if I have a button that when clicked, I want to display a window that gets its information from the app's model using the button's data attribute as the primary key, how is this done?

Is there a way to integrate djdt results with tests?
The problem is djdt is not suitable to be active during tests because it significantly slows down the tests and is unnecessary. But this means that before committing, manual work has to be done to check for query efficiency which is a waste of time and is the whole purpose of tests. I'm thinking it would be nice if there's a way to set a maximum number of duplicate queries/any other metrics, for each view and have it checked by a test. It still would be inconvenient to enable djdt over the entire suite just to enable running just a few tests. How do you usually approach this? I'm using

Learning more about forward and reverse relationships.
Hello there, I am relatively new to django and came to know about forward and reverse relationships and wanted to craft a real world problem. Let's say I have the following classes
class User(AbstractBaseUser):
phone_number=models.CharField()
class ClientPackage(models.Model):
user = models.OnetoOneField(User,,related_name='user_client_package')
package = models.ForeignKey(Package,null=True, blank=True)
expiry_date = models.DateField()
class NotificationSettings(models.Model):
user = models.OneToOneField(User, related_name="user_notification_settings")
master = models.BooleanField(default=True, help_text='set false turn off notifications.')
Now to get all the user\_id and phone\_number of currently active users who have set the master control for notifications to be true I can do it in three ways
1. User.objects.filter(
user_client_package__pacakge__isnull=False,
user_client_package__expiry_date=date.today(),
user_notification_settings__master=True
).values_list('id', 'phone_number')
2. ClientPackage.objects.filter(

HTMX and Wagtail
Hi, has anyone used HTMX with wagtail, I’m very new to using both but I’ve dabbled with HTMX and would love to use it in a wagtail project.
How do HTMX requests work with wagtail page models? As the views are all handled for you.
How does the wagtail admin deal with editing the partial temples?

Streamsync: UI editor + Python
Hello everyone, I've just released Streamsync, an open-source, pip-installable data apps framework.
You build the UI using a visual editor, you write the backend code in Python. No HTML, JS or CSS required. It's an alternative to Streamlit and Dash.

Automating the creation of Forms, Views, and Templates
I'm trying to use a couple loops to automatically build from the models each form, view, and url, and have a single template file render each list. I'm newer to python but I do know generating classes and functions like this is not best practice to say the least, however its something I wanted to try for my own project. What I'm interested in is playing with on the front end with my primary fact table and not the two dozen or so dimension tables, which may require frequent field additions or abstractions.
base/app/models.py
from django.db import models
from django.contrib.auth.models import User
#Create your models here.
class UserTypeModel(models.Model):
code = models.CharField(maxlength = 10, primarykey = True)
name = models.CharField(maxlength = 100, blank = False, unique = True)
def str(self):
return self.name

Review My Python Chat Room Project with Flask and SocketIO
Hey everyone, I just completed a Python chat room project using the Flask web framework and SocketIO library for real-time communication. The front-end was implemented with JavaScript. I would love to get some feedback on my code and project, so I'm sharing it here!
Project Overview: The goal of this project is to create a chat room web application where users can chat with each other in real-time. Users can join different chat rooms and send messages to other users in the same room. The chat room interface is implemented with HTML, CSS, and JavaScript using the SocketIO library for real-time communication with the server.
