In this chapter, we created a full CRUD application. We started by creating a database schema inside of SQLite. Then, we created a Catalyst model for accessing this database. As SQLite doesn't handle foreign key relations by itself, we added information about the relations between tables directly to the DBIC schema files. Once that was set up, we customized the TTSite View and created a page that listed all people and addresses in the database. Then, we created a Controller to edit, add, and delete people. The edit and add actions were simple forms, so we used Catalyst::Controller::FormBuilder to generate and validate the forms automatically. After this Controller was built, we created a similar one to add, edit, and update addresses, again using FormBuilder to generate the form HTML and JavaScript for us.

Overview of this book
<p>Many web applications are implemented in a way that makes developing them difficult and repetitive. Catalyst is an open source Perl-based Model-View-Controller framework that aims to solve this problem by reorganizing your web application to design and implement it in a natural, maintainable, and testable manner, making web development fun, fast, and rewarding.<br /><br />This book teaches you how to use Catalyst to weave the various components involved in a web application, using methods and tools you personally prefer along with recommendations and details on the most popularly used objects like the DBIX ORM, TT2 Template, and Moose.<br /><br />This book will take you from how the MVC pattern simplifies creating quality applications to how Catalyst allows you to tap this power instantly. It explains advanced design patterns and concludes with the improvements that Moose brings to all this. It also incorporates valuable suggestions and feedback received from the community members and our customers. By the end of the book, you will be able to build clean, scalable, and extendable web applications. This book embodies Catalyst's philosophies of Do It Yourself and Don't Repeat Yourself.</p>
