(Any comments would be helpful) How can I authenticate a user who belongs to another database through my other microservice in django rest framework?, i think there is a way to do token based authentication but not sure how to, any help with the resources would be appreciated.

Do you have this database listed in your DATABASES setting?
If you do, you can use User.objects.using('other_db') in a custom authentication class: https://www.django-rest-framework.org/api-guide/authentication/#example

@green dagger Thanks for the response, but the microservice does not access to the main database itself

Do you have the code to determine if a request is authenticated through your microservice?
If yes, wrap that in a custom authentication class as described in the link above.
You'll need to create a proxy user account to associate with it in your django application.
(I think)

Thats the problem, i dont have a method to authenticate the requests made to the microservice
green dagger
Why not? Sorry if that's an obvious question.

Okay maybe I am missing a few strings here, but how do i authenticate a microservice ?
green dagger
It depends on the microservice.
maiden pond
its a todo app

From my perspective you're asking, "how do I use X to authenticate my django app?". In the scenario that I understand X is already built and a known quantity. Is that correct?
maiden pond
yes
green dagger
Who built X / the microservice that you're supposed to be using for authentication?

it is like this situation : So far, I have two separate projects with two separate databases,
- To authenticate the user using simplejwt authentication. (todo_auth project with todo_auth database)
- To show the todo/task information specific to that user. (todo project with todo database)
in this case i want to authenticate apis of 2 using users of 1

Assuming todo_auth is done and is using django-rest-framework-simplejwt, you should be able to authenticate with something like their example: https://django-rest-framework-simplejwt.readthedocs.io/en/latest/getting_started.html#usage
You'll need to use requests or something similar instead of curl though. In your todo project, you'll create a custom authentication class as I linked originally, and make a request to your todo_auth DRF web service. You'll have to check that the token is valid, get the unique user identifer (maybe a separate web service or you'll have to customize the /api/token/ view). Then create a user for that token in todo's database and return that user from your authentication class.
That said, unless you're specifically trying to learn this I would recommend building a monolith.
