=========
|
|
Centralised application configuration.
|
|
|
|
All environment variable reads happen here — once, at startup.
|
|
Blueprints and helpers that need a config value use:
|
|
|
|
from flask import current_app
|
|
value = current_app.config['KEY']
|
|
|
|
Or for values needed at module import time (before app context):
|
|
|
|
from config import Config
|
|
value = Config.COMPANY_NAME
