How to implement audit trail in django?
I need to maintain the audit trail of all the actions and the user responsible for them, in Django. How should I implement it? It will also be great if I have the ability to revert my system to a previous state and replay the actions during an audit. One way is to add some sort of log in every API call. Is there more scalable way? And how to achieve database reversion? -
Which is Better Framework, in terms of handling Large Volume of Data, among Django, Flask, and FastAPI?
I want to know which python framework among Django, Flask, and FastAPI will be best in terms of performance (compute) and speed (latency), for building an API which will be able to handle database with millions if not not billions of records.

How to implement OPA with Django microservices?
I am starting a project where there'll be a bunch of microservices in Django. I want to implement a separate Authentication and Authorization system that all the microservices will talk to for end-user auth. So, my doubts are: What approach should I take? I have looked at OPA and it seems promising but I can't seem to figure out the implementation. I also looked at some other authorization systems like Google's Zanzibar. Is it any good? -
How much people can Django's developement server handle (is suitable for 6 or 7 user at the time)?
I´m currently working on a project using Django, and everything seems to be working fine using the developement server for testing the app in one device (the same device where the command runserver is executed), and this Django project is configured with Xampp's MySQL But now I would like to test my app in several devices for acquiring information from several different users as the project main purpose is to captured certain data (the user write it manually). Would be about 6 or 7 people, so, can I move my project to a desktop computer (by example) and test my app with that amount of people using only the developement server ? or this number of users is more than the developement server can handle ? -

Can't connect Postgres container with Django container on Docker

Postgres shows that it is listening this address listening on IPv4 address "0.0.0.0", port 5432 But Django (psycopg2-binary) shows error django.db.utils.OperationalError: could not connect to server: Connection refused Is the server running on host "0.0.0.0" and accepting TCP/IP connections on port 5432?

Dynamically creating tables using SQLite and django
I am given a task for a web im developing currently. The task is to dynamically create tables as long as the 'save' button is pressed in my web. I am using SQLite for my database. Currently, my codes allow me to do the necessary saving to the existing tables but I am unsure of how to do the following task. Example: I have the fields of 'name' and 'something'. So user type Test for name field and Hello for something field. Upon saving, this name is stored in a existing table and register under a id of 1. At the same time, i want to be able to create a new table with its own field. This table will be named as example_(id). So in this case it will be example_1. Im a beginner in Django and SQL so if anyone can guide/help me in any way, thank you! -

Django Form - How to create a custom form template with a loop for one field?
I'm creating a web app which uses Django's templating engine. Having said that, one of my models is called Order. The Order model, aside from the other models, also uses a model Food - this is a ManyToMany relationship. Food model uses model Category to define food categories (which should contain food categories like Pizza, Burgers, Wine, Beers, etc.) - this is a ManyToMany relationship, as well. Now, I'm trying to create a form where the user will be shown a form with separated categories. As of now, all of the foods from the Food model are just shown one by one, one below another one. They are not categorized in the form template. Currently, they are shown by default, as a simple list of foods where user can choose any of them. I want the user to choose any foods they want, but display them categorically (all of the pizzas under the Pizza category, all of the burgers under the Burgers category, etc.). My models.py looks like this: class Category(models.Model): """ Model for food categories """ name = models.CharField(max_length=100) description = models.TextField(max_length=300) date_created = models.DateTimeField(auto_now=True) def __str__(self) -> str: return f"{self.name} / {self.description[0 : 50]}..." class Food(models.Model): """ Model … -
