Extracting common functionality in Django management commands
I went with app_name/manangement/helpers.py.  No issues.
What is the generally accepted way for isolating functionality that is shared between multiple management commands in a given app?  For example, I have some payload building code that is used across multiple management commands that access a third-party API.  Is the proper location app_name/manangement/helpers.py which would then be imported in a management command with from ..helpers import build_api_payload?
I don't want to put it at the root of the app (we typically use app_name/helpers.py for shared functionality), since it pulls in dev dependencies that wouldn't exist in production, and is never really used outside the management command anyways.
