How to present only one data with foreign key in Django?

In Django and DRF, why would an api route request.user return an AnonymousUser instance, while django.contrib.auth.get_user(request) return the user?
Let's take a very simple route: class Highscore(APIView): def get(request): user = request.user highscore = user.highscore return Response({"highschore":highscore}) For some unknown reason, there are cases in which request.user despite having the user authenticated and logged in (!) return an Anonymous User instance rather than the user itself. However, this can be bypassed by using get_user util function from django.contrib.auth. from django.contrib.auth import get_user class Highscore(APIView): def get(request): user = get_user(request) highscore = user.highscore return Response({"highschore":highscore}) What could be the cause of that? Important note: The user is for sure logged in. So much so that when opening the admin website in a different tab, it recognizes the correct user just from the session. If it is and admin it presents the admin content and if not if give the "you are logged in as ... but this view is reserved for admin users". -

Full text search in MySQL in Django application
I have written Django app and I am using MySQL in it. I'd like to implement full text search but from what I see full text search is supported only for PostgreSQL.

Google Cloud Storage access via service account
I've been repetitively hitting my head against the proverbial brick wall of GCP's Storage API. I'm trying to apply the django-storages module to connect with a GCP bucket for my static files and anything else I want to use it for in the future. According to the django-storages documentation (https://django-storages.readthedocs.io/en/latest/backends/gcloud.html#usage), if you are running in the GCP virtual environment, you set your service account to have Storage permissions via the IAM interface and everything should work like tickety-boo. So, my GCP cloud build runner builds the docker images then runs python manage.py migrate and python manage.py collectstatic before deploying my docker image to CloudRun. The build runner uses a service account called XXXX@cloudbuild.gserviceaccount.com, so going into IAM, I add the “Cloud storage – Storage admin” role, and just to be sure, I also add the “Cloud storage – Storage object admin” role. Now I trigger a re-run of my cloudbuild and ... at the migrate stage I receive the error: ...
