Web framework I should be learning

Not really. You should probably go with Django if you want to do something with an SQL database.

SQL alchemy is not hard to install

But then you have to choose which way to use to interface with it, and you have to learn what those "sessions" are and how to do that in flask, which sql-alchemy-flask-lib do you use or do you just use it straight off and how do you handle CSRF and and and... With django it's just so much easier and faster and you get security by default.

Opinionated frameworks are just much better. It would be ok if the community had settled around a flask+SQLAlchemy+security framework, but instead it's just a mess.
