Overview of this book

<p><br />All businesses have processes that can be automated via computer applications, thereby reducing costs and simplifying everyday operations. This book demonstrates that a modern web application framework makes an ideal platform for such applications. It shows how the attributes that make the Rails framework so successful for Internet applications also provide great benefit within a business intranet. These attributes include easy roll-out and update of applications, centralized processing and data handling, simple maintenance, straightforward code development, and scalability.<br /><br />Ruby on Rails is an open-source web application framework ideally suited to building business applications, accelerating and simplifying the creation of database-driven websites. Often shortened to Rails or RoR, it provides a stack of tools to rapidly build web applications based on the Model-View-Controller design pattern.<br /><br />This book covers topics such as installing Ruby, Rubygems, and Rails on Windows, Linux, and Mac OS X; choosing and installing a database; installing an IDE for Rails development; setting up a Subversion repository to manage your code; creating a new Rails application; understanding Rails models; understanding controllers and views; improving user interfaces with Ajax; using Rails plugins to manage file uploads; using Capistrano to manage application deployment; techniques for scaling Rails applications, such as caching and using Apache to proxy through to the Mongrel server. The example application is straightforward to develop, easy to roll out, and simple to maintain.</p>

Summary


The aim of this chapter has been to show more of the depth and usefulness of Rails, while at the same time demonstrate how to extend an existing application with new functionality. The beauty of Rails is that it is easy to tack new functionality on with extra components, whether new actions for existing controllers, new actions for all controllers, or new models and plugins.

This chapter has hopefully given you the confidence to grow your application to meet new requirements and some guidance about how to go about adding new functionality.

In the next chapter, we'll see how to improve the efficiency and performance of a Rails application: making use of caching, using Capistrano for automating repetitive tasks, and setting up the infrastructure for large scale deployment.
