Catalyst 5.8: the Perl MVC Framework

By: Antano Solar John

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>

Environment setup


Before we start writing our new application, we'll need to create a skeleton again. We can create it using the following commands:

$ catalyst.pl AddressBook
$ cd AddressBook/

We'll also need two more CPAN modules for this chapter. These can be installed from CPAN using the following command:

$ cpan Catalyst::Controller::FormBuilder Catalyst::Controller::BindLex

Note

This should really use FormHandler, which is a Moose-based form handling framework that allows one to use nice object-oriented classes. FormHandler is actively maintained while FormBuilder hasn't been updated since 2007. BindLex has also been deprecated for a while, I think even by its author.

The previous command will ensure that the latest version of each module is installed on your system. After installing the modules, we'll add a special Template Toolkit View called TTSite to our application, using the following command:

$ perl script/addressbook_create.pl view HTML TTSite

TTSite will automatically generate...
