Now that you've deleted the sample row that you added when you created the database, we'll need to implement methods for adding (and editing) a person. As creating and validating HTML forms is a repetitive and boring task (you can write your forms in HTML just like before if you like to), we're going to use Catalyst::Controller::FormBuilder to automatically build our forms. All we have to do is create a definition of the form, and FormBuilder will generate the HTML and validate it when the user submits it. If there's a problem with one of the fields, FormBuilder will return the form to the user with an appropriate message. If the user's browser supports JavaScript, FormBuilder will validate the form on the client side to save a round-trip. (The data will be validated again on the server and rejected if it's bad. This prevents users from turning off JavaScript and submitting bad data.)

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>
