Symfony 1.3 Web Application Development

Overview of this book

With its flexible architecture, the Symfony framework allows you to build modern web applications and web services easily and rapidly. The MVC components separate the logic from the user interface and therefore make developing, changing, and testing your applications much faster. Using Symfony you can minimize repetitive coding tasks, optimize performance, and easily integrate with other libraries and frameworks. Although this framework contains with many powerful features, most developers do not exploit Symfony to its full potential. This book makes it easy to get started and produce a powerful and professional-looking web site utilizing the many features of Symfony. Taking you through a real-life application, it covers all major Symfony framework features without pushing you into too much theoretical detail, as well as throwing some light on the best practices for rapid application development. This book takes you through detailed examples as well as covering the foundations that you will need to get the most out of the Symfony framework. You will learn to shorten the development time of your complex applications and maintain them with ease. You will create several useful plug-ins and add them to your application and automate common tasks. The book also covers best practices and discussions on security and optimization. You will learn to utilize all major features of this framework by implementing them in your application. By the end, you should have a good understanding of the development features of Symfony (for Propel as well as Doctrine editions), and be able to deploy a high-performance web site quite easily.

Preface

Chapter 3. Adding the Business Logic and Complex Application Logic

In the previous chapter we generated the project and modules, built our database, generated the ORM layer, and created a working wireframe of our milkshake application. Now, we can start to generate a working prototype that uses the database.

By the end of this chapter, you will learn how to:

  • Pre-populate the database with test data using Propel

  • Create business logic within the ORM

  • Use an ORM to increase productivity

  • Create more complex routing rules

  • Download and install a plugin

  • Separate chunks of template code into partials

The generated models

Although we have only created five tables, looking in the lib/model folder, and the subfolders of om/ and map/ reveals that there are a total of 25 files. The files that we are interested in are located in the lib/model and lib/model/om folders. The files generated in the lib/model/om folder contain all of the base classes, and the files in the lib/model folder contain the custom classes...
