Pro Active Record

This book walks readers through every step from the basics of getting and installing the ActiveRecord library to working with legacy schema to using features specific to each of today's most popular database engines, including Oracle, MS SQL, and MySQL.

Pro ActiveRecord for Ruby picks up with ActiveRecord where most books on Ruby and the Rails framework leave off. Readers begin by learning about all the built-in assumptions that make it so wondrously easy to create freshly-built Rails applications from scratch. Next, readers learn how to adapt ActiveRecord to work with databasesand this includes just about all preexisting databasesthat were designed without those assumptions in mind. Readers go on to learn how to tie ActiveRecord in with database-specific features such as stored procedures and large objects, how to migrate legacy database designs to work better with ActiveRecord, and how to extend ActiveRecord to provide new and innovative database functionality to their applications. Readers who absorb the knowledge given in this book will have a significant competitive advantage over those with only a superficial knowledge of the topic.

Only book on the market to attack the topic of ActiveRecord, a key component of the Ruby on Rails framework, in such depth Shows how to adapt ActiveRecord to existing databases, which is key to the continued growth of Ruby on Rails Written by recognized experts from thoughtbot, Inc. and Falicon, Inc, experts who will promote the book from their websites, online, and in conference presentations

Pro Active Record helps you take advantage of the full power of your database engine from within your Ruby programs and Rails applications. ActiveRecord, part of the magic that makes the Rails framework so powerful and easy to use, is the model element of the Rails Model-View-Controller framework. It's an object-relational mapping library enabling you to interact with databases from both Ruby and Rails applications. Because ActiveRecord is configured with default assumptions that mesh perfectly with the Rails framework, Rails developers often find they hardly need think about it at all. However, if you are developing in Ruby without Rails, or are deploying against legacy databases designed without Rails in mind, or you just want to take advantage of database-specific features such as large objects and stored procedures, you need the in-depth knowledge of ActiveRecord found in this book. In Pro Active Record, authors Kevin Marshall, Chad Pytel, and Jon Yurek walk you through every step from the basics of getting and installing the ActiveRecord library to working with legacy schema to using features specific to each of todays most popular database engines, including Oracle, MS SQL, MySQL, and more! You'll come to a deep understanding of ActiveRecord that will enable you to truly exploit all that Ruby, Rails, and your chosen database platform have to offer.
