Rails 3.0: It’s ready!

Posted by David August 29, 2010 @ 06:28 PM

Rails 3.0 has been underway for a good two years, so it’s with immense pleasure that we can declare it’s finally here. We’ve brought the work of more than 1,600 contributors together to make everything better, faster, cleaner, and more beautiful.

This third generation of Rails has seen thousands of commits, so picking what to highlight was always going to be tough and incomplete. But here’s a choice selection of major changes for Rails 3:

New Active Record query engine
Active Record has adopted the ARel query engine to make scopes and queries more consistent and composable. This makes it much easier to build complex queries over several iterations. We also delay the actual execution of the query until it’s needed. Here’s a simple example:

users = User.where(:name => "david").limit(20) users = users.where("age > 29")  # SELECT * FROM users  # WHERE name = "david" AND age > 29  # ORDER BY name # LIMIT 20 users.order(:name).each { |user| puts user.name }

Read more in new Active Record guide and watch the Dive into Rails 3: ARel video.

New router for Action Controller
When we switched to a REST-based approach for controllers in Rails 2, we patched on the syntax to the existing router while we were waiting to see if the experiment panned out.

It did and for Rails 3 we’ve gone back and revamped the syntax completely to favor the REST style with less noise and more flexibility:

resources :people do resource :avatar  collection do get :winners, :losers end end  # /sd34fgh/rooms scope ':token', :token => /\w{5,5}/ do resources :rooms end  # /descriptions # /pl/descriptions # /en/descriptions scope '(:locale)', :locale => /en|pl/ do resources :descriptions root :to => 'projects#index' end

Read more in the new routing guide.

New Action Mailer
Action Mailer was born with a split-personality of half model, half controller. In Rails 3, we’ve made the choice to make it all controller. This means that the feel and functionality will be much closer to Action Controller and in fact they now share a bunch of underlying code. Here’s a taste of what it looks like now:

class Notifier < ActionMailer::Base default :from => "Highrise <system@#{APPLICATION_DOMAIN}>"   def new_project(digest, project, person) @digest, @project, @person = digest, project, person  attachments['digest.pdf'] = digest.to_pdf attachments['logo.jpg']   = File.read(project.logo_path)  mail( :subject => "Your digest for #{project.name}", :to => person.email_address_with_name ) do |format| format.text { render :text => "Something texty" } format.html { render :text => "Something <i>texty</i>" } end end end

The new Action Mailer is built on top of the new Mail gem as well. Say goodbye to TMail headaches.

Read more in new Action Mailer guide.

Manage dependencies with Bundler
Managing all the dependencies of a Rails application has long been a hassle of patchworks. We had config.gem, Capistrano externals, custom rake setup tasks, and other incomplete solutions.

Bundler cleans all that up and allows you to specify the libraries, frameworks, and plugins that your application depends on. All Rails 3 applications are born with a Gemfile to control it all. See more on the Bundler site.

XSS protection by default
The internet is a scary place and Rails 3 is watching out for you by default. We’ve had CRSF protection with form signing for a while and SQL-injection protection since the beginning, but Rails 3 ups the anté with XSS protection as well (hat tip to Django for convincing us).

See the Railscast on XSS video and the Dive into Rails 3: Cross-site scripting video for more.

Say goodbye to encoding issues
If you browse the Internet with any frequency, you will likely encounter the ? character. This problem is extremely pervasive, and is caused by mixing and matching content with different encodings.

In a system like Rails, content comes from the database, your templates, your source files, and from the user. Ruby 1.9 gives us the raw tools to eliminate these problems, and in combination with Rails 3, ? should be a thing of the past in Rails applications. Never struggle with corrupted data pasted by a user from Microsoft Word again!

Active Model: Validations, callbacks, etc for all models
We’ve extracted quite a bit of commonly requested Active Record components into the new Active Model framework. This allows an ORM like Mongoid to use Active Record’s validations, callbacks, serialization, and i18n support.

Additionally, in the rewrite of Action Controller, we removed any direct references to Active Record, defining a clean, simple API that ORMs can implement. If you use an API-compliant ORM (like DataMapper, Sequel, or Mongoid), you will be able to use features like form_for, link_to and redirect_to with objects from those ORMs without any additional work.

Official plugin APIs
We also rewrote Railties with the express goal of using the new plugin API for all Rails frameworks like Active Record and Action Mailer. This means that Rails plugins like the ones for DataMapper and RSpec have access to all of the integration as the built-in support for Active Record and Test::Unit.

The new Railtie API makes it possible to modify the built-in generators, add rake tasks, configure default Rails options, and specify code to run as early, or as late as you need. Rails plugins like Devise were able to add much better integration in the Rails 3 version of their plugin. Expect to see a lot more of that in the months ahead.

Rewritten internals
We rewrote the internals of Action Pack and Railties, making them much more flexible and easier to extend. Instead of a single monolithic ActionController::Base, Rails 3 exposes a number of modules, each with defined APIs, that you can mix and match to create special-purpose controllers for your own use. Both Action Mailer in Rails and the Cells project make heavy use of this new functionality.

You can also take a look a this blog post by Yehuda (from last year) to see how the new architecture makes it easy to implement Django-style generic actions in Rails by leveraging Rack and ActionController::Metal.

The Rails generator system is got a revamp as well. Instead of monolithic generators that know about all of the Rails frameworks, each generator calls a series of hooks, such as :test_framework and rm, that plugins can register handlers for. This means that generating a scaffold when using rSpec, DataMapper and Haml will generate a scaffold customized for those plugins.

Agnosticism with jQuery, rSpec, and Data Mapper
The rewritten internals and the new plugin APIs have brought true agnosticism to Rails 3 for all components of the framework. Prefer DataMapper to Active Record? No problem. Want to use jQuery instead of Prototype? Go ahead. Eager to test with rSpec instead of test/unit? You got it.

It’s never been easier to Have It Your Way™ with Rails 3. And at the same time, we’ve made that happen without making using the excellent default stack any more complicated.

Documentation
Rails 3 has had a long development cycle and while that might have lead to some impatience, it has also given book and tutorial authors a chance to catch up and be ready. There’s a wealth of great Rails 3 documentation available already and more is coming shortly.

The Agile Web Development with Rails 4th Ed book is almost ready and there are plenty more books coming. Check out all the new guides, the new official videos, new Railscasts, and a new tutorial. See the recent recap of documentation sources for more.

Installation
gem install rails --version 3.0.0.

We also have a Rails v3.0.0 tag and a 3-0-stable branch.

Rails 3.0 has been designed to work with Ruby 1.8.7, Ruby 1.9.2, and JRuby 1.5.2+.

Gratitude and next steps
I’m personally incredibly proud of this release. I’ve been working on Rails for more than 7 years and the quality of the framework we have today is just astounding. This is only possible as a community effort and Rails 3 has seen so many incredible developers step up and help make this our best release ever (wink). Many thanks to all of you.

We’ll continue to develop Rails 3.0 with fixes and tweaks via the stable branch and Rails 3.1 is already cooking on master.

64. Jessy on 30 Aug 00:23:
    

    Lot’s of things I don’t understand from reading the announcement:

    1. Is Rails 3 thread safe?

    2. Since the Merb team did all the work, why didn’t they get the privellege to writing this post, instead of DHH … especially given that the Merb team was brought in the fix all of DHH fundamental Rails problems.

    3. How does performance compare to Rails 2?

65. ????? ????? on 30 Aug 00:27:
    

    Congratulations Rails team, really great work and very well done.

66. DHH on 30 Aug 00:30:
    

    Chris, Jessy, it long since stopped being about a Rails and a Merb team. Today there’s just a Rails 3 team where everyone is working together for the improvement of the framework.

    See http://contributors.rubyonrails.org/contributors?window=this-year for work done this year. More than 350 people who has commits this year. No factions, just collaboration.

67. Slartibartfast on 30 Aug 00:30:
    

    Thanks guys, I’m getting old you know but I’m still amazed at what the young folk of today can achieve. Though Deep Thought was was pretty impressing I must say so indeed!

70. Rafael on 30 Aug 00:32:
    

    Congratulations! I’m starting a new app right now, with the right foot. Thank you all so much!

71. DHH on 30 Aug 00:32:
    

    Jessy, Rails has been thread safe since 2.3 (so yes). Speed is up in a lot of areas, probably down in a few too. It will depend on your application.

72. Mason on 30 Aug 00:32:
    

    Thanks to all the community efforts, it’s really wonderful!

73. Casey Helbling on 30 Aug 00:33:
    

    Very cool – and very excited to get going with it – great job core team. Thank you very much!

    —-——- One quick note – I think there is something funky going on with the api.rubyonrails.com documentation.

86. Yehuda Katz on 30 Aug 01:11:
    

    I just wanted to say a few things.

    First of all, this is a huge milestone for Rails. From my perspective, this work is three or four years in the making, from the beginning of the Merb efforts, through the merge, and on until the final release of Rails 3.

    From a personal perspective, this release is huge closure for me; I feel like I’ve been working on Rails 3 (and associated projects, like Thor and Bundler) for years.

    When the Merb team merged into the Rails team, we very quickly got to work. The previous animosity actually melted away rather quickly, to be replaced with the somewhat tense, but productive give and take of a core team.

    One of the really amazing things to come out of the last couple of years is a whole slew of new committers to Rails (in addition to Carl and me): José Valim, Aaron Patterson, Xavier Noria and Santiago Pastorino. Rails 3 would still be limping along if not for these guys, who really went above and beyond the call of duty in the past few months to get things past the finish line.

    In light of all this, I really haven’t thought much about the old Merb/Rails party lines in a while. I’ve been too focused on Rails and Bundler, and the rest of the core team (old and new alike) have been busy helping.

87. Dmytrii Nagirniak on 30 Aug 01:13:
    

    NEXT STEP WOULD BE ENSURING ALL THE PLUGINS ARE UP TO DATE.

    I wish we could just `s/not-yet-rails3/already-rails-3/g`

    But I believe WE, the community, will help with that.

    Thanks for the great news!

    Great work! I’ve been waiting and waiting for 3.0.0 final, and here it is

93. Theo Mills on 30 Aug 01:42:
    

    Rails has again surpassed every other software framework with version 3.

    Much like the first version of Rails shook up the software development world, I think Rails v3 will be influencing new frameworks for years to come.

    Thanks for giving this to everyone.

     Though it’s been stable for quite a few releases now, Rails 3.0 was much awaited. one question, the Lighthouse seems to have 55 tickets still for the 3.0 milestone.

     I don’t care too much, because 3.0 works perfectly for me, but I was wondering about their status (are they punted till 3.1, addressed in a patch, or just to be ignored).

     Thanks, and “beyond thanks” for all your magnificent work, Nate

125. xiao on 30 Aug 02:59:
     

     Great job! But,when i use chenese line “redirect_to(@post, :notice => ’’ ??” in controller ,i still get an errror as “invalid multibyte char (US-ASCII)”.do i must add ”# encoding: utf-8” in the controller??

     Kudos to the team on a most excellent release.

     Rails 3 pulls together a lot of discrete goodness into an elegant wholeness that is FUN to use.

     I’ve been using Rails 3 through the Summer and have been very impressed with the evolution of the framework. The improvements strike a fine balance between performance, modularity, and ease of use.

     Your monumental efforts help make this an exciting time to be in software development!

Gratzz !!!

cies on 30 Aug 08:43:

see here a comment from ezmobius of merb fame:

http://news.ycombinator.com/item?id=1644995

i believe rails3 is -technology wise- better named merb2. and the fact that the merb team is so humble to merge with the rails team, and giving up their name in the process is an act of selflessness clearly for the greater good of the ruby webframework eco system.

@DHH: you are right that there is now no longer a merb team and a rails team. true. but this is the big release that was possible only because of the merger, so they deserve to be mentioned/ honoured/ credited, especially in this announcement!

congratulations with the great release. respect to the merb guys for giving up name and fame in order to prevent the ‘fractions’ that DHH talks about in his comment.
