Initialisation using the app factory pattern, requires application context

[philliproso]

If I want to initialise flask-AppBuilder using an application factory pattern I get the standard out of application context error. I can solve this by initialising within the "with app.app_context():", is this continued expected behaviour?

Initialise extensions possibly in a separate file

db = SQLA()
appbuilder = AppBuilder()

Initialise app

app = Flask(name)
app.config.from_object('config')

Initialise extensions

db.init_app(app)
appbuilder.init_app(app, db.session)

Yes, this is the expected behaviour. When you init_app all security permission are checked and inserted if they don't exist. So you need db access on init_app.

I'm using it like this on init.py::

db = SQLA()
appbuilder = AppBuilder()

from app import views

def create_app():
    app = Flask(__name__)
    app.config.from_object('config')
    db.init_app(app)
    with app.app_context():
        appbuilder.init_app(app, db.session)
    return app

On run.py::

import sys
from app import create_app

config = 'config'
if len(sys.argv) > 1:
    config = sys.argv[1]
create_app(config).run(host='0.0.0.0', port=8080, debug=True)

This example accepts the config file as an argument, so you can easilly use diferent configurations for the same app.
