Will Django channels good for to use asynchronous long running background functionality
While working on request where i need to do long running bulk operation on backend ( which takes almost 15-30 min now) for each individual user to avoid load on database.

I saw mostly its used for real time communication not sure will that used for my purpose also. Please suggest thoughts will that be right approach or any other option should i use to perform long running background functionality while using Django.

Linkedin 3-legged OAuth throws 'Not enough permissions to access: GET /userinfo'
I was trying to integrate social login for my Django application using linkedin OAuth2. I have followed steps described in their official page here. In step2, I have given 'profile' value for scope parameter, given below are the allowed scopes in my app. The scopes listed in my linkedin app page.

Questions regarding react in django or react as standalone
I am creating an website using react and Django. To combine Django and react there are 2 ways React in its own “frontend” Django app: load a single HTML template and let React manage the frontend (difficulty: medium) Django REST as a standalone API + React as a standalone SPA (difficulty: hard, it involves JWT for authentication) Now my questions are What are security concerns related to both and which of them is more secure way to do it. In Option-1 we can use both session and token based authentication while in Option-2 we must use token based authentication and XSRF header is needed. Is session based auth better and in what factors it effects If in future I plan to move to react Native for mobile app, which would be more suitable. (I could not find any example when using Option-1) Apparently, Instagram is using session based auth, which means they have used Option-1. Are Option-1 sites SPA based and is Insta SPA based. An extra unrelated question, which is better JWT token auth or Django knox auth. If JWT is better please refer any guide on integrating it with Django. -

Django giving error when trying to get path to static file

Modifying request contents in DRF
As far as I know request objects are immutable and it's bad practice to modify request through closed attributes like request._body or request._data. And since it described everywhere as bad practice, I'm lack of details to understand why it's should be avoided. What is the best approach to dynamically change request (for example if we need to decode value in request.body). As I alternative I can imagine custom Serializer with custom decode serializer.Field but maybe there's more clever solution? Thank you in advance! -
