Programming Ruby 1.9 (3rd edition)

Ruby is the fastest growing and most exciting dynamic language out there. If you need to get working programs delivered fast, you should add Ruby to your toolbox.

This book is the only complete reference for Ruby 1.9, the very latest version of Ruby. (If you’re still using Ruby 1.8, you’ll want to check out the original PickAxe.)

2010 marks the 10th anniversary since the first edition of the PickAxe. We’ve updated the book for Ruby 1.9.2, and we’re making the ebook available in epub and mobi, as well as PDF. (Kindle owners—there’s a lot of code in this book, and the Kindle and code listings aren’t great friends.)

The Pickaxe contains four major sections:

• An acclaimed tutorial on using Ruby.
• The definitive reference to the language.
• Complete documentation of all built-in classes, modules, and methods.
• Complete descriptions of all 97 standard libraries.

This is the reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including all the new and changed methods introduced by Ruby 1.9 and 1.9.2). It also includes all the new and changed syntax and semantics introduced since Ruby 1.8. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, and the new block declaration syntax, among other exciting new features.

Security Update Released or WordPress 3.03

Why is it that WordPress updates are always released the minute before I want to go to bed? WordPress has just released a new update that brings the version of their popular blogging platform to 3.03. The update is a security update which makes it a mandatory update for all WordPress webmasters
hosting blogs on their own servers,

So what’s the security vulnerability about? The WordPress blog states that it is about issues “in the remote publishing interface, which under certain circumstances allowed Author- and Contributor-level users to improperly edit, publish, or delete posts”.

That in turn means that single-author blogs are not affected by the vulnerability directly. Webmasters should still consider updating right away to prevent future damage or indirect damage if someone manages to get access to user accounts on the blog or the ability to create them.

The issue affects sites that have remote publishing enabled. Sites that do not have it enabled are not affected. Then again, it is always a good idea to update to the latest release to close potential security issues right away.

WordPress admins can check if remote publishing is enabled by going to Settings > Writing in their WordPress admin interface.

The update is as usually available directly in WordPress. Users can update their blogs from within WordPress which is the fastest and most convenient solution, or by downloading WordPress from the official website and installing the update manually.

Continuous Testing with Ruby

Feedback. We’re always telling you that you need feedback, with a short feedback gap — the time it takes to get feedback on your decisions, your code, your designs. Well, what if you narrowed the feedback gap to near zero while coding? You’d have continuous testing, a powerful idea that lets you fix bugs while they’re still small and fresh.

Continuous Testing with Ruby shows you how to use a combination of tests, tools, and techniques to immediately detect problems in code, before they spread.

We’ll show you how to set up and run automated tests that check your work continuously as you write code. You’ll start with tools such as Autotest and Watchr, and see how to use them effectively in a continuous environment. You’ll discover the fundamentals of creating and maintaining a test suite that’s Fast, Informative, Reliable, and Exhaustive. You’ll use powerful techniques such as inline assertions—a much better alternative to debugging or console printing. You’ll even use Ruby’s metaprogramming features to quickly find and diagnose problems using existing tests.

But continuous testing isn’t limited to just Ruby; we’ll show you how to extend these ideas and tools to other languages and frameworks, including Ruby on Rails and JavaScript. You’ll be able to create feedback loops that validate decisions made outside of your code: you can automatically verify Rails migrations, instantly check changes to stylesheets and views, and quickly validate documentation, seed data, and other essential configuration and settings.

Many developers today struggle to gain all the benefits of automated testing, due to poorly written or incomplete tests. Continuous Testing with Ruby shows how you can improve the quality of your existing tests and ensure the new tests that you write will do the job. By giving you instant feedback about the quality of your code and the quality of your tests, continuous testing creates a visceral feedback loop that you can actually feel as you work.

Rails Test Prescriptions

Rails Test Prescriptions is a comprehensive guide to testing Rails applications, covering Test-Driven Development from both a theoretical perspective (why to test) and from a practical perspective (how to test effectively). It covers the core Rails testing tools and procedures for Rails 2 and Rails 3, and introduces popular add-ons, including Cucumber, Shoulda, Machinist, Mocha, and Rcov.

Ruby on Rails has unparalleled support for TDD. In addition to the tools that Rails has built-in, a large and thriving testing community adds new tools at an accelerating rate. Rails Test Prescriptions is your guide to the entire Rails testing ecosystem.

Containing both practical code examples and discussion of why testing works, this book starts with the most basic features delivered as part of core Ruby on Rails. Once you’ve integrated those features into your coding practice, you’ll want to use popular third-party testing tools such as RSpec, Shoulda, Cucumber, Factory Girl, and Rcov. Rails Test Prescriptions will show you how to use these tools and when they are appropriate. Rails Test Prescriptions will cover both the current Rails 2.3.x version as well as the initial 3.0 release.

Rails for .NET Developers

Rails for .NET Developers introduces the joy of Ruby on Rails development to Microsoft .NET developers. This book demonstrates the essential elements of both the Ruby language and the Rails application framework, geared especially for developers already fluent in the Microsoft .NET platform.

We then get to the heart of Rails development by showing how to tackle everyday tasks in Rails compared with typical ASP.NET implementations, with a tutorial focus. You’ll build a sample airline reservation system using Rails, learning essential techniques along the way. You’ll come to learn the joy and power inherent in the “convention over configuration” philosophy, the natural elegance of the MVC architecture, and the essence of REST-based design as you develop applications that accommodate web browsers, handheld devices, and even XML web service clients with unparalleled ease.

Along the way, you’ll see good agile development practices, explore test-driven development with Rails. You’ll be prepared for real-world application deployment, and we’ll give you a taste of how Ruby and Rails are reshaping the Microsoft application landscape, including a look at IronRuby.

Ruby on Rails Tutorial

To this day I still hear people complain that Rails has poor documentation. From where I’m sitting this seems far from the truth. Let me lay out the evidence piece by piece:

RailsTutorial.org
To learn Rails from scratch Michael Hartl recently finished his book Ruby on Rails Tutorial: Learn Rails by Example. The book teaches Rails 3 from the ground up and it’s available for FREE online. If you’d rather have a PDF or a book you can grab that as well (and he’s even working on some screencasts).
The source for the finalized book will be pushed to GitHub and released under a Creative Commons License shortly after Rails 3 is done. If you’d like to help translate the book to your language of choice, feel free to contact Michael and he’ll get in touch when it’s time to make it happen.

Rails Guides
If you’re not a Rails newbie don’t forget about the Rails Guides, which have been updated for Rails 3.

Rails API Docs
There are two main websites I use to do API lookups. The first is Rails Searchable API Doc, which has online and offline searchable documentation. The second is APIdock which is online only, but has the ability to comment and easily compare different versions of documentation.

 Rails 3 Free Screencasts
If you’re more of a visual learner (like me) then there are plenty of free screencasts to teach you about Rails 3. About 2 months ago I produced the Rails 3 Screencasts, which will get you started.
Ryan Bates has also produced an incredible amount of Rails 3 screencasts over on Railscasts.com. Ryan has been producing Railscasts for over 3 1/2 years, isn’t that crazy?
There’s also a few good free screencasts over on Teach me to Code by Charles Max Wood.

Keeping on the Edge
If you find yourself wondering how to keep up with all of the newest features / libraries for Rails 3, both the Ruby5 Podcast and the Ruby Show are going strong. Don’t listen to audio? It doesn’t matter, just subscribe to the Ruby5 RSS feed and get links with descriptions to all the newest libraries, tutorials, and more. You might also want to checkout Peter Cooper’s new Ruby Weekly, a Ruby email newsletter.

Need to upgrade a big app to Rails 3?
Jeremy McAnally’s Rails 3 Upgrade Handbook PDF is just $12. There’s also a few paid screencasts for the upgrade over on Thinkcode.tv and BDDCasts.

Need a Book?
There’s a bunch of books that will be coming out after the release, most of which you can start reading now. The Rails 3 Way by Obie Fernandez, Rails 3 In Action by Ryan Bigg and Yehuda Katz, Beginning Rails by Cloves Carneiro Jr and Rida Al Barazi, and of course the Agile Web Development with Rails:fourth edition by Sam Ruby, Dave Thomas, and David Heinemeier Hansson.

In conclusion
No more complaining about lack of good documentation! Seriously. If you want even more Rails 3 content, check out the blog post by Kevin Faustino on 34 Ruby on Rails 3 resources to get you started.

Upgrading to Rails 3

If you’re upgrading an existing application, it’s a great idea to have good test coverage before going in. You should also first upgrade to Rails 2.3.5 and make sure your application still runs as expected before attempting to update to Rails 3. Then take heed of the following changes:

1.1 Rails 3 requires at least Ruby 1.8.7

Rails 3.0 requires Ruby 1.8.7 or higher. Support for all of the previous Ruby versions has been dropped officially and you should upgrade as early as possible. Rails 3.0 is also compatible with Ruby 1.9.2.

1.2 Rails Application object

As part of the groundwork for supporting running multiple Rails applications in the same process, Rails 3 introduces the concept of an Application object. An application object holds all the application specific configurations and is very similar in nature to config/environment.rb from the previous versions of Rails.
Each Rails application now must have a corresponding application object. The application object is defined in config/application.rb. If you’re upgrading an existing application to Rails 3, you must add this file and move the appropriate configurations from config/environment.rb to config/application.rb.

1.3 script/* replaced by script/rails

The new script/rails replaces all the scripts that used to be in the script directory. You do not run script/rails directly though, the rails command detects it is being invoked in the root of a Rails application and runs the script for you.

1.4 Dependencies and config.gem

The config.gem method is gone and has been replaced by using bundler and a Gemfile, see Vendoring Gems below.

1.5 Upgrade Process

To help with the upgrade process, a plugin named Rails Upgrade has been created to automate part of it.
Simply install the plugin, then run rake rails:upgrade:check to check your app for pieces that need to be updated (with links to information on how to update them). It also offers a task to generate a Gemfile based on your current config.gem calls and a task to generate a new routes file from your current one.

You can see an example of how that works at Rails Upgrade is now an Official Plugin

Aside from Rails Upgrade tool, if you need more help, there are people on IRC and rubyonrails-talk that are probably doing the same thing, possibly hitting the same issues. Be sure to blog your own experiences when upgrading so others can benefit from your knowledge!

Ruby On Rails 2.3: Templates, Engines, Rack, Metal, Nested forms

Rails 2.3 is finally done and out the door. This is one of the most substantial upgrades to Rails in a very long time. A brief rundown of the top hitters:

• Templates: Allows your new skeleton Rails application to be built your way with your default stack of gems, configs, and more.
• Engines: Share reusable application pieces complete with routes that Just Work, models, view paths, and the works.
• Rack: Rails now runs on Rack which gives you access to all the middleware goodness.
• Metal: Write super fast pieces of optimized logic that routes around Action Controller.
• Nested forms: Deal with complex forms so much easier.

And that’s just the tip of the iceberg. We’ve put together a complete guide for the Rails 2.3 release noteswhat was deprecated with much more information. Be sure to checkout the section on when you’re ready to upgrade your application.

You install 2.3 with (the final version is marked 2.3.2):

gem install rails
 
If you’re running on Passenger, be sure to upgrade to 2.1.2 as well. Rails 2.3 doesn’t run on older versions of Passenger!

We hope you’ll love it.

Ruby on Rails 3.0 Release Notes

Rails 3.0 is ponies and rainbows! It’s going to cook you dinner and fold your laundry. You’re going to wonder how life was ever possible before it arrived. It’s the Best Version of Rails We’ve Ever Done!
But seriously now, it’s really good stuff. There are all the good ideas brought over from when the Merb team joined the party and brought a focus on framework agnosticism, slimmer and faster internals, and a handful of tasty APIs. If you’re coming to Rails 3.0 from Merb 1.x, you should recognize lots. If you’re coming from Rails 2.x, you’re going to love it too.

Even if you don’t give a hoot about any of our internal cleanups, Rails 3.0 is going to delight. We have a bunch of new features and improved APIs. It’s never been a better time to be a Rails developer. Some of the highlights are:

• Brand new router with an emphasis on RESTful declarations
• New Action Mailer API modeled after Action Controller (now without the agonizing pain of sending multipart messages!)
• New Active Record chainable query language built on top of relational algebra
• Unobtrusive JavaScript helpers with drivers for Prototype, jQuery, and more coming (end of inline JS)
• Explicit dependency management with Bundler

On top of all that, we’ve tried our best to deprecate the old APIs with nice warnings. That means that you can move your existing application to Rails 3 without immediately rewriting all your old code to the latest best practices.

These release notes cover the major upgrades, but don’t include every little bug fix and change. Rails 3.0 consists of almost 4,000 commits by more than 250 authors! If you want to see everything, check out the list of commits in the main Rails repository on GitHub.

WordPress 3.0.2

WordPress 3.0.2 is available and is a mandatory security update for all previous WordPress versions. Haiku has become traditional:

Fixed on day zero
One-click update makes you safe
This used to be hard

This maintenance release fixes a moderate security issue that could allow a malicious Author-level user to gain further access to the site, addresses a handful of bugs, and provides some additional security enhancements. Big thanks to Vladimir Kolesnikov for detailed and responsible disclosure of the security issue!

Download 3.0.2 or update automatically from the Dashboard > Updates menu in your site’s admin area. You should update immediately even if you do not have untrusted users.

WordPress 3.0.1

After nearly 11 million downloads of WordPress 3.0 in just 42 days, we’re releasing WordPress 3.0.1. The requisite haiku:

Three dot oh dot one
Bug fixes to make you smile
Update your WordPress

This maintenance release addresses about 50 minor issues. The testing many of you contributed prior to the release of 3.0 helped make it one of the best and most stable releases we’ve had.

Download 3.0.1 or update automatically from the Dashboard > Updates menu in your site’s admin area.

Note: If you downloaded 3.0.1 in the first 20 minutes of release (before 2200 UTC), you’ll want to reinstall it, which you can do right from your Updates screen. Our bad.

WordPress 3.1 Beta 1

It’s that time in the release cycle again, when all the features are basically done, and we’re just squashing bugs. To the brave of heart and giving of soul: Won’t you help us test the new version of WordPress? As always, this is software still in development and we don’t recommend that you run it on your normal live site — set up a test site just to play with the new version. If you break it (find a bug), report it, and if you’re a developer, try to help us fix it. (Especially you U.S. types who are taking a long weekend for Thanksgiving!)

If all goes well, we hope to release WordPress 3.1 to the world at large by the end of the year, though that is (as always) subject to change/dependent on how the beta period goes. The more help we get with testing and fixing bugs, the sooner we will be able to release the final version.

If you want to be a beta tester, you should check out the Codex article on how to report bugs. Some of the new features to check out include:

• Post Formats (#14746)
• Theme Search (#14936)
• Internal Linking (#11420)
• Admin Bar (#14772)
• Ajaxified Admin (#14579)
• Updated Tiny MCE (#12574)
• Multi-taxonomy Queries (#12891)
• Custom Post Type Index Pages (#13818)
• Admin CSS Cleanup (#14770)
• User Admin (#14696)
• Network Admin (#14435)
• Password Reset Redux (#5919)

There are also some known issues: things that aren’t *quite* finished, but that weren’t worth holding up the beta release. They will be fixed before 3.1 is released for general use. Note that as things get fixed, the beta release will update nightly. What you should know:

• Fatal error: Call to a member function is_page() on a non-object in /wp-includes/query.php. is_page() may be any conditional tag. This issue occurs when a theme or plugin is doing something wrong. Some code is checking the value of a conditional tag before we actually set up the Query, which means they don’t work yet. In 3.0, they silently failed and always returned false. In 3.1 Beta 1, this is throwing a fatal error. This will be handled in the final release, so use this opportunity to fix your plugins. (#14729)
• All known issues slated for fixing before launch are listed in Trac. Please check this list to see if a bug is already on the list before reporting it.

Remember, if you find something you think is a bug, report it! You can bring it up in the alpha/beta forum, you can email it to the wp-testers list, or if you’ve confirmed that other people are experiencing the same bug, you can report it on the WordPress Core Trac. (I recommend starting in the forum or on the mailing list.)
Theme and plugin authors, if you haven’t been following the 3.1, please start now so that you can update your themes and plugins to be compatible with the newest version of WordPress.

Note to developers: WordPress is built by the contributions of hundreds of developers. If you’d like to see this release come out on time, I encourage you to pitch in. Even if you don’t have time to do testing on the beta version, you could help us by contributing a fix for one of the many bugs we already know about.
To those of you in the U.S., have a lovely long holiday weekend, and if you’re looking for something to occupy your post-turkey hours, we hope you’ll take the beta for a spin!
