How to make a fullstack mobile application which handle comments like Facebook
I have a huge question, Do you have any ideas how to make infinite comments area in a flutter mobile application ? For the backend it's seems quiet easy to structure the database. But for the flutter part, I am struggling with the fact that I have to create 'comment' widget dynamically when the user is using the app (when he clicks on 'show more' for example). I think that I should use indexes to structure all the datas and retrieve them in my Flutter application so I can call my backend with the right Id to fetch data. But after when i receive the data how could I incorporate it dynamically in the right place and right order. My casual way to handle things in Flutter is to have a provider how actualize the data everytime I fetch some but I am always fetching all the datas that my provider need. I need to find a way to fetch only few comments and insert them between other comments. I don't know how I can store those potentials infinite data for my comments. With basics Flutter class it seems hard, I was also thinking about making functions which render the … -

when POST order summary, how do i assign quantity to each product mentioned
Im building e-commerce app. During checkout, the id of products inside the cart (and other info) get POSTed to ORDER table on my backend. My ORDER table has many-to-many relation with PRODUCT table, I cant figure out a smart way of saving on the server, how much of each product was in the cart during the checkout I was thinking of adding a second HelperORDER table where i would combine quantity and product.id but that doesnt seem very elegant. Here is how the structure of ORDER looks when you GET it "id": 11, "product": [ { "id": 1, "name": "gloomhaven" }, { "id": 2, "name": "mtg" } ], "order_date": "2022-11-14", "notes": "testaasdasdsadadadaaaaORDER", ideally it would look like this but i cant figure out how to handle it elegantly "product": [ { "id": 1, "name": "gloomhaven" "quantity" 2 }, { "id": 2, "name": "mtg" "quantity" 3 } ], -

How is "secret_key.txt" more secure in Django project?
I apologize if this is a duplicate question but I can't find an answer online. In Django Checklist Docs I see the following to keep secret key secure. with open('/etc/secret_key.txt') as f: SECRET_KEY = f.read().strip() My project is deployed with AWS EBS. I've created a separate file called "secret_key.txt" which holds the key. How is this more secure than keeping the key in the settings.py config file? If someone can access my projects settings.py file to access the key, would they not be able to access the "secret_key.txt" file as well? How is creating a "secret_key.txt" file more secure? I've checked Google and Stack Overflow for reasoning but can't find an answer. Currently all sensitive information is protected using an .env file and including this file in .gitignore. -
Correct way to close down RabbitMQ and Celery?
I'm using Django to call a Selenium script through Celery and RabbitMQ as a message broker. The problem I'm having is often changes I make to my Selenium script aren't actually changing anything when I rerun my Django server. It sounds weird but I feel like something is still using my old code, not the one with the changes I make. My guess is that this is something to do with RabbitMQ being kept running while I make changes to my Selenium script? Do I need to 'refresh' it somehow each time I make changes or re-start the process? Also, I just ctrl+C to close everything when I'm finished, is there a 'proper' way to close down each time? -
