Learn to build dynamic, interactive web applications using the two most important approaches to web development today: Ajax and the phenomenally efficient Ruby on Rails platform. This book teaches intermediate to advanced web developers how to use both Ajax and Rails to quickly build high-performance, scalable applications without being overwhelmed with thousands of lines of JavaScript code. More than just recipes, you also get a thorough, low-level understanding of what's happening under the hood. Beyond the how-to, Ajax on Rails helps you consider when Ajax is (and isn't) appropriate, and the trade-offs associated with it. For those new to Rails, this book provides a quick introduction, the big picture, a walk through the installation process, and some tips on getting started. If you've already started working with Rails and seek to deepen your skill set, you'll find dozens of examples drawn from real-world projects, exhaustive reference for every relevant feature, and expert advice on how to "Ajaxify" your applications.
I bought this book in the big book sale in San Francisco fort mason to support the community and I have been interested in reading Oriely Books. In general, they approach teaching computer science by providing many great links and examples that live beyond the book’s life, and this one is no except. Although RJS is no longer used, it is great to see how they were approaching having JS and rails together. Some of the early segments of the books talk about link_to_function which I use still now a days and its interesting to see what happens in the source code. Although most of the book is not applicable now, and the book no longer supports digital updates, it was a cheap find and cool to reminisce in rails improvements. Get it for the history, not for rails 4+ dev for sure
