Ruby on Rails

Ruby on Rails Programming – An Inside Look

As Ruby on Rails has emerged as a popular agile web development framework, the Beta release of Rails 3.0 features an evolution of the platform. Whether you are a dedicated PHP developer interested in Rails or have actively used the framework, it is important to understand Rails 3.0 in the context of the larger web development framework. As impressive as version 2.3 was, 3.0 marks a natural evolution in the agile framework that extends and simplifies the development process with Ruby.

Streamlining the process of development, class dependencies are now properly included in the framework, making it much easier to integrate common Javascript libraries such as jQuery with helper classes. To understand the future directions of web frameworks, independent of your preferred coding language, the inner workings of Rails 3.0 can provide deeper insights into the development process. Rather than having to re-write your code base from scratch, the Ruby team built a dependency system known as Bundler, which quickly gets your installation up to speed with the latest framework standards in Rails 3.

While the core Rails libraries remain independent and can operate on their own, the management software can simplify the process or allow you to work on your own development path. As we look to future trends in web development in general, Rails 3 provides a roadmap for understanding broader trends in Model View Controller (MVC) frameworks.

How Rails 3 modernizes the MVC Model

Many developers struggle with understanding layers in an MVC framework, and Rails can help provide insights into the runtime status of various processes. Rails’ 3.0 integrated instrumentation features allow developers to benefit from the rich sources of information that logs can provide during testing and development.

Designed to streamline the entire development cycle, Rails continues its path toward a production-centric framework. In the desire to move toward a flexible development platform, Rails itself has become modular which is one of the most significant shifts in development frameworks in recent years. The core elements within the Rails framework such as Records, Controllers and Mailers have become independent extensions, allowing for easier framework customization based upon your requirements.

Optimization with Ruby on Rails

Increased demands on modern databases for web development require ongoing optimization of database queries. As a result, the Rails’ Active Record module has the ability to refine queries before they are built within SQL itself. With an intermediate step you can define sub-classes, allowing you to add conditions on the queries which can significantly improve load times.

If you look at a history of modern web development, both PHP and Rails point squarely toward a tighter integration with JavaScript and a more object oriented approach. With Rails 3.0, the applications themselves are an object within class Rails::Application, allowing you to centralize all your configuration parameters in a single file, config/application.rb.

With the active beta release of Rails 3.0, the Ruby on Rails team is focused on further refining libraries for development. The core of the framework is now more flexible and stable, helping Rails to emerge from a favorite of startups to an enterprise-level framework built to scale.
