How to access app.config in a blueprint?

Question

I am trying to access access application configuration inside a blueprint authorisation.py which in a package api. I am initializing the blueprint in __init__.py which is used in authorisation.py.

__init__.py

from flask import Blueprint api_blueprint = Blueprint("xxx.api", __name__, None) from api import authorisation 

authorisation.py

from flask import request, jsonify, current_app  from ..oauth_adapter import OauthAdapter from api import api_blueprint as api  client_id = current_app.config.get('CLIENT_ID') client_secret = current_app.config.get('CLIENT_SECRET') scope = current_app.config.get('SCOPE') callback = current_app.config.get('CALLBACK')  auth = OauthAdapter(client_id, client_secret, scope, callback)   @api.route('/authorisation_url') def authorisation_url():     url = auth.get_authorisation_url()     return str(url) 

I am getting RuntimeError: working outside of application context

I understand why that is but then what is the correct way of accessing those configuration settings?

----Update---- Temporarily, I have done this.

@api.route('/authorisation_url') def authorisation_url():     client_id, client_secret, scope, callback = config_helper.get_config()     auth = OauthAdapter(client_id, client_secret, scope, callback)     url = auth.get_authorisation_url()     return str(url) 

Answer 1

Use flask.current_app in place of app in the blueprint view.

from flask import current_app  @api.route("/info") def get_account_num():     num = current_app.config["INFO"] 

The current_app proxy is only available in the context of a request.

Overloading record method seems to be quite easy:

api_blueprint = Blueprint('xxx.api',  __name__, None) api_blueprint.config = {}  @api_blueprint.record def record_params(setup_state):   app = setup_state.app   api_blueprint.config = dict([(key,value) for (key,value) in app.config.iteritems()])
