I'm using python-social-auth but my app isn't logging out when the user logs out of Google
I have python-social-auth working to authorize my app and everything works great. I can log into my app via OAuth2 and log out via typical Django logout. My problem: if a user logs out of Google (from GMail, for example), it does not log me out of my Django app. I am still authorized as the Google user even though Google is logged out. I have tried refreshing tokens via the load strategy below to "force" a check to make sure Google is still logged in and that isn't working. social = request.user.social_auth.get(provider='google-oauth2') access_token = social.get_access_token(load_strategy()) social.refresh_token(load_strategy()) I feel like I'm going down the wrong road. All I want to do is validate that Google is logged into still so I can consider my OAuth2 session valid. Is there a way to do this integrity check? What am I doing wrong or do I need to do? My research so far suggests what I want is not even possible - I don't like that answer so hoping for a different one here. -

Django Foreign Key to Filtered Object got errors: django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet
I have problem that i never face before.

Make, migrate model programmatically, and reload / repopulate django application's new settings / configurations
I am making a model programmatically using the following code: modelObj = type(m.get("name"), (models.Model,), m.get("attrs")) After that I am trying to run the makemigrations, migrate, and autoreload command using the following code. def migrate_and_reload(): management.call_command("makemigrations") lm = MigrationRecorder.Migration.objects.filter(app=modelObject._meta.app_label).last() management.call_command("migrate", modelObject._meta.app_label, lm.__dict__.get("name"), "--database==test") from django.utils import autoreload autoreload.restart_with_reloader() But: And, get the Message from autoreloader that the server port is already use If I comment the autoreloader then Migration is not run into the database. However, Makemigration works and a migration file is created in the app's migration folder) My basic goal is to register the dynamic model programmatically, make respective migrations (handle any errors if there), migrate it to Db, and reload the server I will prefer not to reload the server, but seems like I have no other options to reload all the settings or populate the configurations in Django 3.0.3.
