Product Description
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 Rails model/view/controller framework. Its 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.
About The Author
Kevin Marshall is a software developer at heart. He is a consultant to a number of companies and currently runs 50+ sites of his own&emdash;many of which are now happily taking advantage of ActiveRecord with the Ruby on Rails framework, including the popular Draftwizard.com. As a technology writer, Kevin has published a short article, "Web Services with Rails"; contributed a few recipes to the Ruby Cookbook; and contributed a number of articles to the Association of Computing Machinery's periodical, Computing Reviews (available online at www.reviews.com).
Kevin is also a member of the Pro Football Writers Association, the Fantasy Sports Trade Association, and the Fantasy Sports Writers Association. When he's not deep into coding, building content, or talking football, he's generally off playing with his sons.

Customer Reviews & Comments
Right at the start of Pro Active Record the authors address a possible problem some may have with it: that there's not enough in Active Record to warrant a full book. They point out that the basics are well covered as sections elsewhere but that this is the first book to really dig into working with legacy schema and other `advanced' uses. That's fair enough, but after reading the book I am still left with the question of why, then, they dedicate the first half to covering ActiveRecord's most basic concepts? Judging from postings on the rails email list, there's certainly a lot of confusion about ActiveRecord, associations, observers, how to work with legacy table names and primary keys, and so on. But in a book with a title prefix of "Pro" I was expecting to jump straight into the nitty gritty of topics like compound/composite primary keys and performance tuning, probably with some real world examples, and maybe with a serious exploration of AR's internals. As it is, such topics only get a quick treatment in the final chapter (the compound/composite primary keys section is a paragraph referring users to a plugin). It's almost always instructive reading other developers' code and it would be unfair to claim that I didn't spot a couple of tips that may prove useful, but they were passing things. And sometimes I found myself wondering what happened to the tech review process, particularly in the coverage of the has_one association, where not only is the variable naming confusing, but they seem to be calling the each method on a single ActiveRecord instance. I'm left wondering what the audience is for this book. The title and blurbs suggest it's pitched at people who want to go deeper into ActiveRecord than they have before, but the content is better suited for someone with some database experience who wants to pick up ActiveRecord to write some scripts. As it is, if you've worked with ActiveRecord before your time will be better spent writing plugins and exploring the internals for yourself, and if you've not you'll get most of the same material from a decent Rails book and some time exploring. Disclaimer: I was sent a copy of this book for review by the publisher.
