python - flask - how to redirect outside of app context -

i'm trying simple redirect function not decorated @app decorator, how can (presumably need create check_status() aware of app context)?

def check_status(): homecoming redirect("http://google.com") @dashboard_bp.route('/dashboard') @login_required def website_users(): check_status() homecoming render_template('website_users.html')

the context active globally. when phone call check_status() website_users(), context active.

not redirect() callable needs context; produce response() object, no context required.

you are ignoring homecoming value of check_status() however. perhaps need check if check_status() returning something:

status = check_status() if status not none: # redirect homecoming status

alternatively, create check_status() raise exception. can handle exception in view (and turn redirect response there), or can register errorhandler() function handle dedicated exception:

class statusdenied(exception): pass @app.errorhandler(statusdenied) def redirect_on_status_denied(error): homecoming redirect("http://google.com") def check_status(): raise statusdenied

python http flask
