Redirect back in Flask
I'm using the helper function which is recommended here: http://flask.pocoo.org/docs/reqcontext/
def redirect_url(default='index'): return request.args.get('next') or \ request.referrer or \ url_for(default)Use it in in the view
def some_view(): # some action return redirect(redirect_url())Without any parameters it will redirect the user back to where he came from (request.referrer). You can add the get parameter next to specify a url. This is useful for oauth for example.
instagram.authorize(callback=url_for(".oauth_authorized", next=redirect_url(), _external=True))I also added a default view if there should be no referrer for some reason
redirect_url('.another_view')
The snippet you linked basically does the same but more secure by ensuring you cannot get redirected to a malicious attacker's page on another host.
