Riding Rails: Rails 3.0: Beta release

Rails 3.0: Beta release

Posted by David February 05, 2010 @ 03:33 AM

You thought we were never going to get to this day, didn’t you? Ye of little faith. Because here is the first real, public release of Rails 3.0 in the form of a beta package that we’ve toiled long and hard over.

It’s surely not perfect yet, but we were out of blockers on the list, so here we go. Please give it a run around the block, try to update some old applications, try to start some new ones, and report back all the issues you find.

I’m really proud of this moment, actually. We’ve had more than 250 people help with the release and we’ve been through almost 4,000 commits since 2.3 to get here. Yet still the new version feels lighter, more agile, and easier to understand. It’s a great day to be a Rails developer.

There’s plenty to get excited about here. A few of the headliner features are:

Brand new router with an emphasis on RESTful declarations
New Action Mailer API modelled 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

But please take a look at the full release notes and enjoy the latest!

To install:

gem install tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n
gem install rails --pre

Notes: The first line is required because RubyGems currently can’t mix prerelease and regular release gems (someone please fix that!).

But the weekend is a whole day away! Massive thanks to the Rails team, really exciting stuff! Fun time to be a Rubyist.
Jeremy Kemper on 05 Feb 03:46:

You can use gem install rails3b to grab the whole list of beta dependencies at once.
David Chelimsky on 05 Feb 03:47:

Looks like there is also a dep on i18n before you can add rails—pre.
Chris on 05 Feb 03:48:

Great news. I’m really looking forward to testing it out on some existing apps.

Thank you!!
Tony Pitale on 05 Feb 03:55:

Important to note another dependency that has been mentioned in every other post on Rails 3: Ruby 1.8.7 is required. Just in case.
Dillon on 05 Feb 03:56:

Martijn van Brandevoort on 05 Feb 09:29:

It looks like this release is going to be all it was promised to be and more. Very impressive! Congratulations.

Now there’s no excuse left to upgrade those ancient Rails 1.2 applications..
iceskysl@gmail.com on 05 Feb 09:53:

Due to a rubygems bug, you must uninstall all older versions of bundler for 0.9 to work
Adrioano on 05 Feb 10:08:

Very good. Thanks very much.
Juanma Cervera on 05 Feb 10:13:

First of all, Great work guys, and thanks.

And then, one problem, just after building a new app for following Jeremy McAnally’s last tutorial, when I try to start the server with ‘rails server’ mongrel hangs, but webrick works fine.

I left here a log of the problem. http://gist.github.com/295698

Maybe anybody has some idea of what’s happening?

Thanks again.
itsme on 05 Feb 10:21:

Thanks for all the hard work!

There are a lot of gems that have to be updated to run with rails 3. E.g. paperclip, subdomain-fu, thinking-sphinx, ...

Yes I know it’s beta, but is there a compatibility list of running gems?

Thanks!
Fabio on 05 Feb 10:43:

@itsme: http://wiki.rubyonrails.org/rails/version3/plugins_and_gems
Bakastyle on 05 Feb 10:49:

Finally!!!!!! Great day!
Michael van Rooijen on 05 Feb 10:51:

I just ran these commands:

gem install tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n gem install rails—pre

And last night I was thinking: “I wonder when Rails 3 beta will be released.”

Thanks! Can’t wait to mess with this!
Sunil on 05 Feb 10:53:

great work! Proud to be a rails developer :)
RailsBlob on 05 Feb 10:59:

I just farted!
grigio on 05 Feb 11:20:

Even “rake” is requied, thanks for the beta!
Great on 05 Feb 11:23:

That’s great but I really fear that the decoupling will lead to more complexity like in J2EE where you can choose whatever framework for persistence, templates, etc… so awful that made me go for rails

I would have preferred to see Rails closed in it’s core architecture.
Mike Williamson on 05 Feb 11:52:

“It’s a great day to be a Rails developer.”

So say we all.
Michael Johann on 05 Feb 12:02:

With Rails 3 coming close it’s time to start writing the JRuby chapter of our Rails 3 book.
Wonderful ! on 05 Feb 12:23:

You guys rocks !

Thanks for providing us such a good framework that transforms programming into climax :) on a daily basis !
bmsatierf on 05 Feb 12:34:

Also requires i18n gem.
Maurizio De Magnis on 05 Feb 12:50:

Great Work! Thanks!
Martin on 05 Feb 12:55:

Awesome!
BurmajaM on 05 Feb 12:55:

I had problem installing Rails 3 beta. gem install rails—pre asked for rack >= 1.0.0 though I had rack 1.1.0 installed. After manual installation of rack 1.0.1 previous install instruction installed rails 2.3.3. Problem was in gem sources. I had http://gems.rubyonrails.com there. Just remove it and rails 3.beta will be installed.

Just my 2 cents.
Juanma Cervera on 05 Feb 13:03:

@Juanma Cervera (that’s myself, but it may be interesting for somebody with same problems)

I could make mongrel start adding these gems to Gemfile

gem “cgi_multipart_eof_fix” gem “fastthread” gem “mongrel_experimental”

All these gems ar require in mongrel.rb with statements like Mongrel::Gems.require ‘mongrel_experimental’

This might have meaning for someone.

Wiehann on 05 Feb 13:05:

thanks for this guys!!! try it out as soon as I have time!
Wheres_the_beef on 05 Feb 14:23:

Is this going to solve the speed issues now? Will it work with Apache without all that configuration bull** I used to do? Will it work out of the box without configuring FastCGI or having to learn what the hell Mongrel is.
Chris A. on 05 Feb 14:25:

Tax refund and Rails 3 in one day… can this be? Or am I dreaming?
Andrea on 05 Feb 15:35:

The scaffold didin’t change at all, why didin’t you guys used:

respond_to :html, :xml, :json and respond_with(@users = User.all)

to make it better?
Cs on 05 Feb 15:40:

Excellent job guys, we are very proud of you!
Artur on 05 Feb 15:44:

Arse on 05 Feb 17:54:

I have a problem, i’m developing my first rails 3 app, but if i don’t do javascript_include_tag(:defaults) and include all the prototype libraries i can’t use the method => :delete in my links… but i’m using jquery! I’m forced to include prototype all the time?
Carl Lerche on 05 Feb 18:14:

@Arse try generating a new app with rails—jquery
Kevin Elliott on 05 Feb 18:23:

Congratulations! I have to thank you for all the hard work that the 250 volunteers put in. Without this community (including all the participants in the forums, irc channel, mailing lists, guides, etc) I can’t imagine that Rails would be as successful. It’s this community that makes Rails that much more pleasurable to use.

Thanks everyone!

Chris on 05 Feb 19:05:

Thanks for all of your hard work! I’ve really been looking forward to this.

@Carl Lerche Hi Carl, i get a “command not found” error with rails—jquery, the help don’t talk about this command :(
John T on 05 Feb 19:29:

Having a problem on Windows XP (yeah, yeah…) after using the rails command to create a new test app, then from within the app’s directory, trying to use the rails command (rails console, rails generate, etc.) returns an error:

Johannes Jörg Schmidt on 05 Feb 21:37:

Oh my god. Those Rails related Sites like Github and Gemcutter are down or not responding, gem is reporting

ERROR: http://gems.rubyforge.org/ does not appear to be a repository

and I can’t wait to try that biggest Rails release since 0.9. hanging with an empty /var/lib/gems/1.8/gems/rails3b-3.0.0/ for whatever reason.

Great work! Keep on going, Thank you all!

Greetings Johannes
Johannes Jörg Schmidt on 05 Feb 21:44:

The biggest but tinyest Release in one I would say…
Jerod Santo on 05 Feb 22:47:

Great release everybody!

How can I get my hands on a rails.js that relies on jQuery instead of Prototype? I Tried rails new_app—jquery to no avail. Are there some external generators I need or something?
Arse on 05 Feb 22:56:

@Jerod Santo You can find it here http://github.com/rails/jquery-ujs/. The helpers work fine, too bad that :method => :delete seems bugged, so the destroy links don’t work. Maybe this we’ll be fixed tomorrow :)
Frank on 05 Feb 23:37:

Cutting my way through all this butt kissing, and hoping that my little message will get noticed. I apologize deeply for disturbing the group masturbation over this tiny release, but has anyone actually tried to upgrade the simplest of 2.3 projects? The rails upgrade plugin is the biggest joke since somebody’s alter ego said that Rails scales well. Starting a server with an empty test app, generated by rails 3, is a journey through the jungle, dangerous and moist. No, it’s not the humidity in the jungle air, it’s the tears I shed before I was “[w]elcome[d] aboard” and notified that I was “riding Ruby on Rails.” I must offer my heartily congratulations on giving a new meaning to the word “Beta”.

In the end, I can do nothing but quote David, “Note: [...] someone please fix that!”
Wheres_the_beef is an idiot on 05 Feb 23:57:

No one owes you anything…

Arno.Nyhm on 06 Feb 01:12:

1) is there an easy way to upgrade ruby 1.8.6 to 1.8.7

2) whats prefered? to run it on 1.8.7 or on 1.9.1?
Khalid Shaikh on 06 Feb 05:08:

Great job guys!!! I just installed it!
Mikey on 06 Feb 11:02:

119, Arno.Nyhm:

You can look at the gem rvm which do it easy to run multiple versions.
Phil McClure on 06 Feb 11:38:

When I try to start the server with “rails server—debugger”, I get an error “You need to install ruby-debug…”. However, I already have ruby-debug installed.

Testing www.co2cut.com on rails 3
-jul- on 06 Feb 16:54:

So far rails 3.0.0.beta and ruby 1.9.1 are not friends. In order to install rails, you need rubygems 1.3.5, but ruby 1.9.1 has rubygems 1.3.1 bundled. According to rubygems developers, hand-upgrading it causes errors: http://rubyforge.org/tracker/index.php?func=detail&aid=27087&group_id=126&atid=575
mgutz on 06 Feb 17:57:

@jul been learning 3.0 pre and 3.0 beta on 1.9.1p378 . works for me
Trys on 06 Feb 18:45:

For windows users who have problems with “exec” try replacing in file <path_to_ruby>\lib\ruby\gems\1.9.1\gems\railties-3.0.0.beta\bin\rails

line

exec(Dir.getwd + ’/script/rails’, *ARGV)

with

load Dir.getwd + ’/script/rails’

Should get you started.
Matthew Ratzloff on 06 Feb 19:45:

Things that would be nice: if the code checked for the existence of dependencies before trying to use them, and returned helpful messages instead of exceptions if they are missing. :-)

Francois on 07 Feb 00:28:

I am looking forward to taking rails 3 for a spin. The list of improvements looks great. Hats off to all of you who worked on this.
mark mcdonald on 07 Feb 05:19:

Re-wrote a complete app in rails 3. Works excellent! So far I have used resource_controller and formtastic as plugins which both work without conflicts. Thanks for all the hard work everyone.
Al on 07 Feb 11:15:

Is there anyone getting this error when running script/server? “Cannot find gem for Rails =1.2.6.0:” Thanks
Andy on 07 Feb 14:20:
@Ruby1.9 Users Before installing Rails 3, upgrade your system, i.e.,:
```
gem update --system
```
If you used `rubygems-update’ instead, then you might want to uninstall that first:
```
gem uninstall rubygems-update
```
```
gem update --system
```
Now you should be ready for Rails 3!

Is there some kind of roadmap for Rails 3 – i.e.: When will Rails 3 be finished?

I just recently started to juggle with Ruby on Rails and do not want to learn it 2 times :-D
Fred on 08 Feb 05:44:

Merb is cool than ror, but now its ror!

Wow, I have to try this now ;-)
Dabazz on 08 Feb 09:39:

Awesome
Gary Taylor on 08 Feb 10:35:

This is a major milestone. I too would feel proud of this release. I stepped through the startup code and per request code yesterday, and it is that clearly written and well structured – it feels like you wrote it yourself 5 minutes ago. Very easy to understand and hopefully will be quick.

Well done to all of those contributors.

Eric J Gruber on 09 Feb 06:50:

I’m concerned about the use of “rails server” et. al., instead of “ruby script/server”.

You’d better make sure you’re in the right directory, or you’re going to generate a new app in a subdirectory if you make a mistake.

Is that a fair concern, or is there a safeguard built in to prevent that from happening?

Any idea ?

It surely is a great day to be a Rails developer :)

Great Work!

Thank you。rails在中国的应用会越来越多的。
Charles on 10 Feb 14:27:

After updating my rails to the beta I can’t create a project in a previous version of rails (example: rails 2.3.5). I tried the old way (rails 2.3.5) to create a project in a previous version of rails but I have a message indicating this ==> /Library/Ruby/Site/1.8/rubygems.rb:827:in `report_activate_error’: RubyGem version error: railties(3.0.0.beta not = 2.3.5) (Gem::LoadError) from /Library/Ruby/Site/1.8/rubygems.rb:261:in `activate’ from /Library/Ruby/Site/1.8/rubygems.rb:68:in `gem’ from /usr/bin/rails:18

Is that a missing command in the beta or will it be impossible to create a new project with a previous version of rails after Rails 3.0 ?
Jim on 10 Feb 15:32:

Awsome! Can’t wait to try it out.

Is there a version of api.rubyonrails.org updated for 3beta yet?
daniel on 11 Feb 01:19:

the command to install it doesn’t work as rack-mount needs to be exactly 0.4. so run

gem install rack-mount—version=0.4.0

before gem install rails—pre
Tex on 11 Feb 10:15:

1 Trillion of trillions of thanks !!!
Dobril on 11 Feb 12:16:

Awsome! Thanks
Blacky on 11 Feb 12:29:

Is there a roadmap for the Release Candidates of Rails 3 ?
Shibumi on 11 Feb 21:14:

Installs without problem on Mac OS X with jruby 1.4.0 except rack-mount v-0.4.0 exception which is fine after fixing version issue, thanks to daniel…
Samiron on 12 Feb 12:55:

I faced somewhat similar problem of daniel. rack-mount and rake should be of a specific version. I had to run following two commands additionally
```
gem install rack-mount -v 0.4.0
```
&
```
gem install rake 0.8.3
```
Anyway, thanks a lot for the post :)
Alex on 12 Feb 16:47:

That’s great!

Thank you

What happened to subdomain support in routes? :(
what wrong on 14 Feb 14:18:

$ rails server

.../config/boot.rb:6:in `require’: no such file to load—bundler (LoadError)

$ gem list

bundler (0.9.5, 0.9.4)
noname on 14 Feb 19:13:

might add sqlite3-ruby to the first gem install line since rails -v breaks without it
Ajin Nikam on 15 Feb 15:53:

Thanks guys Great job

Abhishek shukla on 18 Feb 05:24:

Thanks guys… it’s going to be fun.
Duane Johnson on 18 Feb 06:10:

This worked for me on Mac OS X Leopard, with a clean install of Ruby 1.9.1 (installed with MacPorts):

$ sudo gem install thor text-format mail i18n tzinfo builder memcache-client rack rack-test erubis rake

$ sudo gem install rack-mount -v 0.4.0

$ sudo gem install rails—pre

Awesome work!
Adrien Lamothe on 18 Feb 20:59:

Will Rails 3 have the planned new plugin architecture? I don’t see mention of that in the current release notes.

Congratulations!

Adrien
Eddie Cianci on 19 Feb 16:45:

@adrien Plugin changes are in the release notes:

http://guides.rails.info/3_0_release_notes.html#rails-architectural-changes

They also link to http://yehudakatz.com/2009/07/19/rails-3-the-great-decoupling/ for more information.
Wickyd on 23 Feb 09:35:

No-one has answered the most pressing of questions.

Will there be an improvement in speed?

Will a rails 3 web application “feel” faster?
Yaok on 24 Feb 14:15:

where is the Rails 3.0 guides
Westy on 24 Feb 16:34:

Hello,

When will the stable version of rails 3 be available?

I’m new to rails. What’s the impact on my current application, which is built on 2.3.3.

Cheers
David Pan on 25 Feb 03:53:

Congratulations…

I really love the features of Rails 3.0
Black Programma on 02 Mar 00:47:

i think rails 3 is racist cuz it dont have the language we can unda stand. i think u should include sum ebonics in it – aint ever thing white people u know. some people aint like you. be open minded.

Grrr…as usual very frustrating to get RAILS on Windows XP. Here are the steps I used to be able to start developing: 1) Downloaded the RubyInstaller for 1.8.7-p249 (cannot find 1.9.2 anywhere?) from http://rubyinstaller.org/download.html and ran it. 2) Issued command: ruby -v | confirmed 1.8.7 3) Issued command: gem install tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n | Which failed on bundler because it requires RubyGems 1.3.6 4) Issued command: gem update—system | This updates Gems to 1.3.6 5) Issued command: gem install bundler | to finish rails requirements 6) Issued command: gem install rails—pre | 7) Issued command: rails myapp | to create sample app 8) Issued command: rails server(which I think will be an issue) | recieved the following error: c:/ruby/lib/ruby/gems/1.8/gems/railties-3.0.0.beta/bin/rails:2:in `exec’: Exec format error – C:/Ruby/apps/myapp/script/rails (Errno::ENOEXEC) from c:/ruby/lib/ruby/gems/1.8/gems/railties-3.0.0.beta/bin/rails:2 from c:/Ruby/bin/rails:19:in `load’ from c:/Ruby/bin/rails:19 9) Thanks to @Trys I did the following: edit <path_to_ruby>\lib\ruby\gems\1.8\gems\railties-3.0.0.beta\bin\rails at line: exec(Dir.getwd + ’/script/rails’, *ARGV) replace with: load Dir.getwd + ’/script/rails’ 10) Issued command: rails server(which I think will be an issue) | recieved the following error: c:/ruby/lib/ruby/gems/1.8/gems/bundler-0.9.10/lib/bundler/resolver.rb:163:in `resolve’: Could not find gem ‘sqlite3-ruby (>= 0, runtime)’ in any of the sources. 11) Issued command: gem install sqlite3-ruby | finsihes but gives alot of no definition for * messages 12) Issued command: rails server | server started but sqlite3.dll gives a popup error 13) Download sqlite3.dll from http://www.sqlite.org/sqlitedll-3_6_10.zip and place in \WINDOWS\system32 14) Issued command: rails server | success 15) Browsed to http://localhost:3000 | Rails Screen! Yeah that was painful!

I experienced this on 2 different machines….I really like programming Rails but setting up and upgrading components has always been a headache.
Otto on 04 Mar 20:05:

Part of speed is in database and the way you are using it.

So, I’m not sure the new engine is the only thing to help you speed up your app.

From what I’ve seen it really helps in time development and usage. Speed is quite complex to measure and depends on so many factors (CPU, memory tuning, server, etc.)

I’ve seen application waisting time just with “simple” request to a database that was not properly configured or tuned.

Let’s enjoy the new features, stability and speed will come

If Rails 3 uses:

rails console # instead of script/console

... and …

rails g scaffold post title:string # instead of script/generate scaffold post title:string

... but we still create a Rails app with:

rails myapp

... then would it be beneficial to create a Rails app with something like:

rails a myapp

... or …

rails app myapp

... or something like that to avoid name-space or key word collisions (e.g.: in case I wanted to create a Rails app called “console” or “server”)?
