Practical Rails Projects 65

Posted by samzenpus
from the read-all-about-it dept.
Sean Cribbs writes "There are many beginning and advanced Ruby on Rails books available, from the authoritative Agile Web Development with Rails to the cookbook-style Rails Recipes. However, healthy guidance for intermediate-level developers is lacking at best. Ironically, this is the most crucial stage in the process of becoming proficient with Rails because one must begin to learn why, not just how. Eldon Alameda's Practical Rails Projects effectively fills that gap. I know Alameda from our local Ruby User Group and spoke with him frequently while he wrote this book. His expertise with Rails definitely shines through in the hefty 621-page volume." Keep reading for the rest of Sean's review.

summary A strong book for the intermediate Rails developer
Practical Rails Projects has a unique and effective approach. Instead of spoon-feeding contrived code snippets, Alameda teaches by example, leading the reader step-by-step through the design, creation, enhancement, and analysis of several full-fledged projects. Each project introduces new techniques to the intermediate Rails developer carefully and with plenty of explanation — from caching to generating graphs to RESTful application design and much more. Rather than regurgitating documentation that is occasionally unclear or misleading, each application begins with a clean Rails project and is built up step-by-step with detailed commentary on how and why each step is taken. Alameda's format reflects the reality that real-life projects never have a straight development path; at each step one must make tough decisions, watch for pitfalls and take risks. There are no leaps-of-faith or "just trust me" moments, everything is explained. In the final chapter of each project, Alameda also suggests ways that the project could be improved and how to apply the newly learned techniques to previous projects in the book.

The text is clear and uncomplicated with an approachable style. Projects even makes Rails' least fun framework, ActionWebService (which helps you create SOAP and XML-RPC services), easy to understand. While there are some glaring proofing mistakes, such as "Ruby" uncapitalized and some malformed URLs to external resources, the code snippets are practically error-free and all source and binary resources are available via the Apress website.

One controversial decision made by Alameda was to use the ExtJS Javascript library extensively in one project to build an administration interface for a legacy site. ExtJS is a powerful high-level library that simplifies the creation of desktop-like interfaces in the web browser. Instead of spending a lot of time hand-crafting HTML/ERb templates and CSS, Alameda quickly creates an interface in ExtJS and uses Rails to generate XML and JSON that drives the almost entirely client-side application. While some may find this outside the spectrum of what should be in a Rails book, many developers are now creating their interfaces in Flex, SilverLight, and other client-side technologies. With the recent official release of ActiveResource, I believe we will see more web-service-focused Rails applications as time goes on. Alameda's choice is also practical; with a small number of users having access to the interface, he can place greater requirements on them in order to deliver the application more quickly.

Overall, I believe Practical Rails Projects is a strong book for the intermediate Rails developer. It provides an introduction to more advanced concepts of the framework without being preachy or obtuse. It lacks any discussion of test- or behavior-driven development with Rails, but the breadth and depth of the topics it covers makes up for this weakness. Like any book that covers a rapidly-changing open-source project like Ruby on Rails, Projects will date quickly, but in the near-term it should be of great help to developers looking to gain constructive experience.

      You should have used modrails [modrails.com]. Suddenly, Rails deployment is as easy as PHP deployment. I no longer hesitate to put up little toy apps [infoether.com] since now I don't have to worry about mongrel clusters and init scripts and all that rot. Great stuff!
      • Do you find configuring Mongrel Clusters (usually just a command-line switch or two) difficult? Strange, nobody else seems to. And I am also curious: why do your "little toy apps" need init scripts in the first place?

    This book was published in October, 2007, and Rails 2.0 was released December, 2007. According to the description on Amazon, only the last example deals with 2.0 at all.

    Since there were some rather significant changes introduced in Rails 2.0, it is likely that many of the examples will no longer work as described. I know that is the case with current version Agile Web Development with Rails.

      I guess that would depend on your definition of current. There is a new version in beta [pragprog.com] that has already been largely updated, and continues to actively follow Rails development.

      I was thinking the same thing, in particular ActionWebService has been replaced by ActiveResource, and much of the controller/routing code seems to cater to REST URLs.

    I've found that Rails documentation falls into two categorys: (1) The annoyingly pedantic tutorial which falls apart if anything whatsoever goes wrong on your system, since the tutorial lacks any depth; and (2) Advanced docs that are moderately impenetrable to people not already very familiar with the relevant technologies.

    I'm an experienced Perl and C guy who just wants to find a better way than CGI::Ajax to build slick web applications, but I found that I spent more time being annoyed with the documentation than actually learning. Intermediate indeed; Rails needs this.

      I tried learning rails from Agile Web Development with Rails first, and I found that AWDwR has a huge deficiency: it frequently fails to explain the fundamental Ruby concepts and structures that it's using. (For example, I remember typing in the :symbol syntax for several chapters without having any idea what it actually was.).

        David Black's Ruby For Rails [manning.com] is a great book for this; David explains the way Rails leverages all sorts of Ruby techniques to do what it does. Another good one is Advanced Rails [oreilly.com], which has an excellent section on the changes that Rails makes to various Ruby core classes - e.g., Symbol.to_proc.

    The Art of Rails [amazon.com] covers intermediate Rails topics quite nicely, and just came out so it had the chance to cover some of the Rails 2.0 developments (particularly related to nested routes and REST services). I've been reading through a copy and have found it really helpful so far -- especially the three chapters on advanced Ruby development patterns.

  • After playing around with ruby on rails, I just didn't find that it was all that useful. Mostly I found it was just a painful exercise in learning exotic ways of doing things that I already knew how to do correctly. SQL, for example. Don't get me wrong, I see some merit in the rails way of doing things, but overall rails just seems like two steps back for anyone savvy enough to comprehend ruby in the first place.
    Ruby, on the other hand, rocks out loud.

      Convention over configuration and ActiveRecord are hardly exotic. I must admit I loved it when I discovered the Dynamic finders.
    • I did not "get" Rails at first either. But now that I am familiar with it, I can do things in moments that it used to take half a day programming to do.

      True, there is strong incentive to "go with the flow", and learn the "Rails Way" to do things... but most of the time that actually helps rather than hinders.

      ActiveRecord doesn't do SQL "correctly" for very good reasons. If you have a reason why you need to use SQL like it was designed, you probably shouldn't be using ActiveRecord at all. However, that does not preclude you from using the rest of the Rails framework.
