Django not deleting session id in mongoDB database when logging out

[keshavadk]

I have integrated the MongoDB database with CVAT.
I get "Could not login" Error when I try to login second time into CVAT portal.
I get below error in browser console
"FAILED SQL: INSERT INTO "auth_user_groups" ("user_id", "group_id") VALUES (%(0)s, %(1)s)"
I know that this is because django has not deleted the session id in database in auth_user_groups collection for first time login-logout.
How can I fix this issue and make sure I will be able login-logout multiple times without having to manually delete session id in mongoDB ,auth_user_groups collection.

Hi, we have never tried to use a database backend that Django does not natively support, and we have no plans to support MongoDB in the future. CVAT doesn't have the logout logic implementation and use Dgango rest auth package for this https://github.com/openvinotoolkit/cvat/blob/6e49f1b36b78fddbfd88646132ddde0b3e407bf1/cvat/apps/authentication/urls.py#L17. So I would suggest asking the authors of this package about your issue.
P.S. Why postgres doesnt meet your requirements and you want to use MongoDB?
