Access Flask config outside of application factory

Question

I\'m currently using the Flask Application Factory pattern with Blueprints. The issue that I\'m having is how do I access the app.config object outside of the application fa

Answer 1

There is no need to use global names here, that defeats the purpose of using an app factory in the first place.

Within views, such as in your example, current_app is bound to the app handling the current app/request context.

from flask import current_app

@bp.route('/')
def example():
    servers = current_app.config['CUPS_SERVERS']
    ...

If you need access to the app while setting up a blueprint, the record decorator marks functions that are called with the state the blueprint is being registered with.

@bp.record
def setup(state):
    servers = state.app.config['CUPS_SERVERS']
    ...
