How to create a similar to "setUp" method in unittest using pytest fixtures and django
I have the code below in my test files and trying to refactor it.

Heroku config for a Django app that requires a Firebase JSON?
I have a Python Django app deployed on Heroku that uses Firebase through the drf-firebase-auth library (which I must use for a number of reasons). I know that configuration shouldn't be checked into version control, but I'm not sure how to avoid it in my case. The drf-firebase-auth library requires the Firebase credential JSON file to be saved in my code's directory structure. How can I pass this JSON essentially via Heroku environment variables without needing to commit the JSON file to my git repo (and push to Heroku), so that I can have a proper config setup for staging/production/etc? The drf-firebase-auth library instructs me to add this to my settings.py and also to save my very sensitive firebase.json file to my codebase: DRF_FIREBASE_AUTH = { 'FIREBASE_SERVICE_ACCOUNT_KEY': 'project/config/firebase.json' } The implementation within this 3rd party library looks a bit like this: import firebase_admin from drf_firebase_auth.settings import api_settings ... firebase_credentials = firebase_admin.credentials.Certificate( api_settings.FIREBASE_SERVICE_ACCOUNT_KEY ) firebase = firebase_admin.initialize_app(firebase_credentials) ... The problem is that I would like to avoid committing this Firebase JSON to git in order to deploy to Heroku. -
Proper way to run nameko service(s) inside a Django application?
If I have a vanilla Django REST (DRF) application and I would like to integrate a nameko service (specifically an event_handler event listening service), what's the best way to achieve this? I cannot simply nameko run a service if it's part of a Django application. I'm considering running the nameko service via a custom Django management command, but would I lose some of nameko's features, say, scalability? Eg. nameko maintains a pool of 10 workers per nameko run (if I remember correctly). -
