rdelon writes "TurboGears was previously mentioned here as "Python on Rails". It has since made tremendous progress and is now a popular Python web MVC framework (along with Django). IBM developerWorks just published a great article about TurboGears and a book is on the way. Unlike Rails and Django, TurboGears is made up of several pre-existing subprojects. One of the great features of TurboGears is the 'toolbox,' which allows you to configure and check various aspects of your application and database in a browser."

rdelon writes "Finally there is some movement in the hosting provider control panel department. cPanel and Ensim have been around for years but some people have grown increasingly frustrated with them. WebFaction has developed a new type of control panel. It offers an Ajax web interface that decouples the application from the domain: the root of a website might be served by Ruby on Rails while the /blog URL might be served by WordPress; reciprocally, multiple websites might be served from a single Django application, which reduces the resource usage on the server. A screencast demo of the control panel is available on their blog."

Robby Russell writes "ONLamp.com has published another article by Curt Hibbs titled, 'What is Ruby on Rails?.' In this article, Curt goes on to discuss all the major components of the popular Rails web framework and shows it does a lot of the heavy lifting for you. This article highlights all the major features, from Active Record to Web Services, which are going to be included in the upcoming 1.0 RC release of Ruby on Rails. With one book published already and four more on the way, do you think Rails will continue gaining as much popularity in the coming year?" An interesting follow-up to the two part tutorial from earlier this year.

matt_j_99 asks: "With all the talk about Ruby on Rails, I've been thinking about PHP frameworks. Ruby on Rails looks pretty cool, but frankly, I don't want to learn a new language. It seems that with all the slashdot discussion about RoR, somebody always makes the valid point that PHP is not a framework. But with PHP5's, Object Oriented features, a standard framework might emerge. Prado, Carthag, BlueShoes, and PHITE all seem like interesting frameworks. What PHP frameworks have you used in your applications? What were the pros and cons of each? Which framework do you think will have the best chance of long-term viability and maintenance?"

ucahg writes "Simon Willison has a post on his blog introducing Django, a rapid web development framework he and his colleagues are releasing into the wild. Hailed as Python's own version of a Rails framework, Django looks very promising. I'll be keeping a close eye on it as it gets more and more support..."

Robert J. Berger writes "The Ruby on Rails team announced that "After the longest gap between releases since Rails was made public and after more than 225 fixes and new features, the final major release before the 1.0 milestone has arrived." This is a major update to what is to many developers consider the new tool for developing sophisticated interactive database driven web applications. It integrates backend Model/View/Controller object-oriented model with AJAX based clients so that the developer can focus on the app and not on the details of basic mechanisms. You really can do much more with much less coding. The new release adds a completely rewritten visual effects engine, drag-and-drop capability including sortable lists, and autocompleting text fields to Rails. All building on top of an upgraded version of Prototype, the javascript foundation for Ajax in Rails ... Check out the very cool demos at script.aculo.us."

Ridgelift writes "Learning to develop web applications with Ruby on Rails has gained a huge amount of interest lately, but for people wanting to learn Rails there are no books on the subject. That's changed now with the pre-release of Agile Web Development with Ruby on Rails , the latest book from Dave Thomas and the author of Ruby on Rails David Heinemeier Hansson. It's really 3 books in one: a full Rails tutorial, an in depth guide to the components that make up Rails, and an introduction to developing applications using the Agile development model. There's even a quick introduction to Ruby, the language Rails is built with." Read on for an early review of the beta book. Full disclosure: Reviewer Miles K. Forrest points out that he has read earlier versions of the book's manuscript and provided critiques to the authors. Agile Web Development with Ruby on Rails author Dave Thomas and David Heinemeier Hansson pages 506 publisher The Pragmatic Programmers, LLC rating Excellent reviewer Miles K. Forrest ISBN (Book still in beta) summary A complete primer to developing web applications with Ruby on Rails

At just over 500 pages, Dave Thomas' new book manages to cover a lot of ground in a concise, readable manner. One problem at the outset -- the book is not finished. Knowing that the Ruby on Rails community has been chomping at the bit for morsels of information, Dave and David (DHH) have answered the call by releasing the forthcoming book early. "The book has not had a full technical edit, so it will contain errors. It has not been copy edited, so it will be full of typos. And there's been no effort spent doing layout, so you'll find bad page breaks, over-long lines, incorrect hyphenations, and all the other ugly things that you wouldn't expect to see in a finished book. We can't be held liable if you follow our instructions, expecting to create a Rails application, and you end up with a strange shaped farm implement instead. Despite all this, we think you'll enjoy it!"

And enjoy it I did. The "Getting Started" section of AWDRoR provides a whirlwind overview of the Ruby on Rails' architecture. I found Rails to be very intimidating at first. You can't just cut-and-paste a couple lines of code like you can in PHP. Rails generates all kinds of directories and files, making it feel like your first trip to Disneyland -- you know there's fun to be had, but it's a big place and you don't know your way around. The reason for all this is because, in programming, short simple scripts are easy and simple, full blown Web applications are not. Many LAMP projects developing in perl/Python/PHP and any number of templating engines have started simple, but grown into unruly messes that are difficult to maintain. While trying to grok Ruby on Rails, topics like Model-View-Control and Object-Relational Mapping really don't stick at first. Add to the confusion that many of us are also struggling to learn Ruby and a RDBMS (such as MySQL; Rails works with others databases as well). The overview of Rails is necessary, but I found it to be a lot more helpful rereading it after completing the tutorial section. So if you read through this first section and feel lost like I was, just know that the material will become familiar to you and press on, because it gets a whole lot easier from here on in.

I really enjoyed the Tutorial section, a narrative designing a shopping cart application for a customer. Dave says it best: "Does the world need another shopping cart application? Nope, but that hasn't stopped hundreds of developers from writing one. Why should we be different? More seriously, it turns out that our shopping cart will illustrate many of the features of Rails development. We'll see how to create simple maintenance pages, link database tables, handle sessions, and create forms. Over the next seven chapters, we'll also touch on peripheral topics such as unit testing, security, and making our pages look nice."

Dave begins not with lofty design plans, but with a tool most real programmers use: napkin drawings. Many of us sit down over coffee with a customer and talk about what they need, sketching out ideas with paper and pencil, not some complex software planning tool. Each chapter in the tutorial section allows a story to unfold, where the customer works alongside the developer. Real life situations like changing direction or refactoring code are covered as each programming session is done. You really see why Rails is becoming so popular. It wasn't written by a team of programmers trying to hammer out an arbitrary list of features, but rather Rails was built around a real application (Basecamp). Pragmatic considerations such as developer time, feature creep, and maintenance issues have all been skillfully addressed in Rails. The tutorial reflects this, and at the same time it also gently, almost unknowingly, teaches principles as outlined in the agile manifesto. Some of the goals include:

• Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan

AWDRoR can get away with this because Rails itself was designed around the principles of Agile software development. The tutorial is probably the best I've ever read. You really come away from it knowing not only what you've written, but why, as well as picking up a few expert developer tips along the way.

The third section, "Rails in Depth," dives into the inner workings of Rails. Components such as ActiveRecord, ActionController, ActiveView, and Web Services (Ajax) are all covered well. There are even chapters on securing and deploying your applications properly. These chapters, in conjunction with the API docs found on www.rubyonrails.org, give a full overview of Rails. Most helpful in this section are the notes and diagrams which help pull everything together. The appendices that cap off the book also provide the full tutorial source code, as well as a brief introduction to Ruby, the language that makes all the magic happen.

In short, Rails is a brilliant architecture, and Agile Web Development with Ruby on Rails is a great book. I'm reluctant to point out its shortcomings as it's still in beta, but it's really hard for me to find much to complain about. It took me some time for the light to come on with Rails, but once it does, you see that Rails could not exist without Ruby, the language it's inextricably woven into. As Dave Thomas is quoted on www.rubyonrails.com, Rails is probably "the framework to break Ruby into the mainstream." Whether you believe the hype or not of "super productivity," "Ten times faster development," and "Better than anything else," Ruby on Rails is a great tool to add to your belt. In fact, I find myself using it exclusively for Web apps, and I catch myself using python and PHP less and less and Ruby more and more for my day to day programs.

If you want to learn Ruby on Rails, Agile Web Development with Ruby on Rails is a great choice, and will probably be the definitive book on the subject.

Paradox writes "Java developer Justin Gehtland recently tried re-implementing one of his web applications in Ruby on Rails instead of his normal Java Spring/Hibernate setup. His analysis of overall performance and application size was startling, to say the least. The Java app's configuration alone was nearly the size of the entire Rails codebase, and Rails application was significantly (15%-30%) faster! At the same time, the Ruby community is abuzz because Ruby is getting a new optimized bytecode compiler for its upcoming 2.0 release. Will Ruby on Rails become even faster as a result?"
