So all models are ready when connecting to the db and so our "db" object has all models listed on it, create a function to load all models from the media_types, etc. Call it in setup_database() Problem: This gives celery warnings, because celery is imported before being setup properly. No idea how to fix this now. So media-type loading is excluded from load_models for now.
