A complete REST API example

In this recipe, we will convert the API structure created in the previous recipe, Creating a SQLAlchemy-independent REST API, into a full-fledged RESTful API interface.

Getting ready

We will take the API skeleton from the previous recipe as the base to create a complete functional SQLAlchemy-independent RESTful API. Although we will use SQLAlchemy as the ORM for demonstration, this recipe can be written in a similar fashion for any ORM or underlying database.
