Run management commands on Django server in a Linux hosted App Service in Azure. Anything other than cronjobs?
Please Excuse me if this question has been posted before.I have a linux hosted App Service in Azure running a Django server. I want to run a management command periodically on the server. I am somewhat of an inexperienced person as far as cloud and architechure goes. So please be as elaborate as possible, mentioning the reasoning behind your recomendations, so that I can learn more. Tried using Cronjobs but it was not consistent and I did not have access to logs. Can't use Webjobs since the app service is on a linux machine and webjobs aren't supported on linux machines. Have read that funtions can be used. If so please point me in the right direction on how to setup and connect function to the App service and run command. -

user need to submit the feedback and in my models I'm having user field which is associated with User instance, now don't want to expose my user filed
Users need to submit feedback, and in my models, there's a "user" field associated with a User instance.

I implemented auto save function in my Django 4 web app using js and django view function but it keep saving new model instances at every interval
I have implemented auto save feature in my Django 4 web app using javascript and Django views.py function as the end point.I got it to save the form / model instances to database, bypassing the django forms validation. The problem now is that it keep saving new instances at every interval. The correct behavior is to create the first instance and at subsequent interval only update the database with new data if there has been changes since the last auto save. The problem is i don't know how to store the id of the model instance that was just created so that at every call of the auto save javascript i can check if this auto save request a new request or existing request. I have not tried anything yet at this point. Getting it to this point where I can save the unchecked form/model instance already took a lot of time for me. -

Django storing environment variables
I'm making a Django chat project in which all messages are encrypted when sent and decrypted when read. I have this task: “Use a standard cryptographic algorithm (such as AES) to encrypt and decrypt messages. The encryption key must be unique for each user session and stored in a secure location (for example, in environment variables or using a key management system)." I can't figure out how to store the per-session encryption key inside environment variables. My understanding is that static data like the secret key is stored inside environment variables, but it doesn't change on every session. How should I implement the functionality described in the task? -
How to redirect request from Django to FastAPI
I have a Django API and a FastAPI wrapper. Requests will be sent from clients to Django, but I want to redirect them to FastAPI to do some role check (I can't do it in Django for some reasons) then sent it back to Django. For now, I am able to sent request from FastAPI to Django using FastAPI's middleware; but I cannot write a proper middleware for Django to do the same (I am just started with Django for 1 week). Can someone please suggest a solution? -

How to implement caching for tokens in Django Rest Framework and Firebase Auth
I'm building an API using Django Rest Framework and I was thinking about using Firebase for authentication. I have some questions about how to implement the caching layer. **This is how the application works: ** A user logs in using the frontend (React.js), then when I make an API call to DRF and I pass the auth token sent back by Firebase. Using that token, DRF calls Firebase again to retrieve the user, and finally I retrieve the UserProfile for that user in DRF by querying a Postgres db. I want all this operations to result in the least amount of calls to Firebase, hence I was thinking about caching the (user token, user id) pair. However, I have never implemented caching in Django before and would appreciate any guidance. Also, what caching strategy and tool can you recommend me? Thank you -

Representing NFT wallet addresses in Django model fields
I'm building a Django app that involves working with NFTs, and I want to know the best way to represent NFT wallet addresses using a Django model field. NFT wallet addresses are typically hexadecimal strings, but I'm not sure how to design the model field to accommodate them efficiently. I think the best option is a customization of the CharField with a length constraint to store the hexadecimal address. But is there a recommended maximum length for NFT wallet addresses? I'd exclude UUIDField and TextField. I'd appreciate any examples and recommendations. Thank you!
