I use Flask and Flask-SQLAlchemy for a while now. Doing so i spent a lot of time in searching for the solutions for different problems. See this as my notebook of helpfull snippets. I will update this post from time to time because i don’t want to create a new blog post for each line of helpfull code.

Querying a certain year by a datetime column:

This return all invoices from 2012.
