By now you should be familiar with using SQLAlchemy to work with a relational database. We covered the benefits of using a relational database and an ORM, configured a Flask application to connect to a relational database, and created SQLAlchemy models. All this allowed us to create relationships between our data and perform queries. To top it off, we also used a migration tool to handle future database schema changes.

In Chapter 3, Templates and Views we will set aside the interactive interpreter and start creating views to display blog entries in the web browser. We will put all our SQLAlchemy knowledge to work by creating interesting lists of blog entries, as well as a simple search feature. We will build a set of templates to make the blogging site visually appealing, and learn how to use the Jinja2 templating language to eliminate repetitive HTML coding. It will be a fun chapter!
