This is a demo site showing one way to use Flask to make a website. I used a SqlAlchemy non-declarative model, and simple sqlite test db. Semantic-UI for the front-end CSS HTML rendered server-side with the Jinja2 template engine. Vagrant upload, you can start the website starts with:
> vagrant up
? (enter password at prompt)
> vagrant ssh
> cd projects/todoapp
> python application.py
** Requires Virtualbox, Vagrant, & Git **
