There is only a finite number of queries that can be made (~15.000). However, for technical reasons some queries sometimes fail, e.g. when a user misspells a query. In most cases everything is handled well but I do occasionally see some fringe cases that break the app and the users get a white screen. My question: is there some simple solution that could help me iterate over the list of possible queries (that I have) to check if they ever break the app? I can imagine that a bash script could do this and just list all cases which didn't return 200/OK from the server, but maybe there is a nicer way to do it? I already looked at http://flask.pocoo.org/docs/0.12/testing/ but have no experience with this and need some quick fix before I learn how to write proper Flask unit tests... I'll be thankful for any tips! Best, Piotr -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: Thanks Vladimir! I am already using Sentry (and I love it, I highly recommend it to anyone running Flask web apps). However, I wanted to take a proactive approach here and check before the users learn the "hard way". Maybe indeed the only way is to set up unit tests and check if returned response by the app is correct. If anyone has more ideas, I will be happy to hear them!

URL: From spaceman at antispaceman.com Fri Feb 16 07:42:59 2018 From: spaceman at antispaceman.com (spaceman) Date: Fri, 16 Feb 2018 12:42:59 +0000 Subject: [Flask] Flask-Login and Flask-Session Message-ID: <20180216124259.C79658B6@home.antispaceman.com> I wonder if anyone can help me as my knowledge of python isn't good enough figure this out: I am using Flask-Session with the RedisSessionInterface (works by itself) but I also trying to use Flask-Login with a custom session interface as specified here: https://flask-login.readthedocs.io/en/latest/#disabling-session-cookie-for-apis I am pretty certain the code specified there won't work with the RedisSessionInterface as it is using flask's default session interface. I tried this: class CustomSessionInterface(RedisSessionInterface): """Prevent creating session from API requests.""" def save_session(self, *args, **kwargs): if g.get('login_via_header'): return return super(CustomSessionInterface, self).save_session(*args, **kwargs) But the RedisSessionInterface requires arguments (three to be exact) to configure it properly. My initialization looks like: ... from flask_login import LoginManager from flask_redis import Redis from flask_session import Session, RedisSessionInterface ... redis.init_app(app) app.config['SESSION_REDIS'] = app.extensions['redis']['REDIS'] session.init_app(app) app.session_interface = CustomSessionInterface() login_manager.init_app(app) ... I need to take the session interface that initialized by Flask-Session and turn it into a CustomSessionInterface with the login_via_header set so that my api won't return a session cookie but still use the RedisSessionInterface, and my simple brain can't do that.

My initialization looks like: just decided provide the variables myself like so: app.session_interface = CustomSessionInterface(None, '', None) using the CustomSessionInterface.
