When I run...
$ script/generate
I get a list of installed generators and a message saying "More are available at http://wiki.rubyonrails.org/rails/pages/AvailableGenerators." However, the indicated wiki page says "This topic does not exist yet."
Does there exist some central repository of downloadable Rails generators?
In particular, I'd like one that creates the Rails scaffolding, but uses Haml instead of ERB.
It would also be neat if it would generate the Test::Unit tests but using the Shoulda enhancements.
That wiki was a wonderful resource back in the day, but it's long gone. I threw up a archive containing that page from when the wiki started wobbling. It's dated but you can at least see what was there.
As for now, look for gems (especially plugins) to provide the generators rather than expecting them as isolated resources. The gems command can be used to find whats available.
A lot of plugins come with their own generators. The one that springs to mind is restful_authentication because I have used it quite a bit.
Edit: Did you google here?
There's Rails Boost, which is a template generator. In fact, the template you want has already been generated -- that one uses HAML and Shoulda.

I have installed CKeditor for my Rails app and while doing the Formatting, the Formatted code does not display in the screen, instead, HTML is rendered, like this
<h2><strong>In this project</strong> you’ll create a simple blog system and learn the basics of Ruby on Rails including: Models, Views, and Controllers (MVC) Data Structures & Relationships Routing Migrations Views with forms, partials, and helpers RESTful design Using Rails plugins/gems The project will be developed in five iterations. I0: Up and Running Part of the reason Ruby on Rails became popular quickly is that it takes a lot of the hard work off your hands, and that’s especially true in starting up a project. Rails practices the idea of "sensible defaults" and will, with one command, create a working application ready for your customization. Setting the Stage First we need to make sure everything is set up and installed. See the Environment Setup page for instructions on setting up and verifying your Ruby, Rails, and add-ons. This tutorial was created with Rails 4.0.0, and may need slight adaptations for other versions of Rails. Let us know if you find something strange! From the command line, switch to the folder that will store your projects. For instance, I use /Users/jcasimir/projects/. Within that folder, run the rails command:</h2>
Use the html_safe method
So, something like:
puts my_variable.html_safe

I'm learning RSpec for a while and reading some articles, books and other resources. But I wonder if is there any complete real life Rails project, that using RSpec, with source codes available to examine. I study some gems and Ruby projects but still I think it would be better to see a Rails project's source code in action.
Discourse is a large, real world project you could take a look at.
They use RSpec and you can view all their testing code here.
Another huge open source rails app using rspec is spree commerce https://github.com/spree/spree
I have a nice set of fixtures that I use for testing. When a request test fails it is handy to run the app interactively with the test fixtures loaded. But if I run the full server with -e test I get all kinds of crazy errors, probably having to do with the pipeline.
-- edit --
When I visit the home page I get this in the browser:
I say it's crazy, because I don't understand it :) In particular, I am using twitter-bootstrap and I am unclear about sass/scss/css work with Twitter Bootstrap + Rails so it's highly likely that I have some detail wrong in how I am using them together (or that the gem twitter-bootstrap-rails has some bug.)
Ah, much better question :-).
The twitter-bootstrap-rails gem uses LESS, which is similar to SASS in what it does, but not the same. SASS is the default for Rails, and a good choice. If you want to use SASS, (and based on the error, it appears you are), then use the Bootstrap SASS gem instead, linked here. It may be possible to use both LESS and SASS together, but that seems like a Bad Idea to me.
Check out Ryan Bates' excellent RailsCast which covers using Twitter Bootstrap in Rails. It covers both alternatives. And then fork over the $9 to get Pro access to his continued RailsCast with more details.
I want to get into rails by examining well built code
where can i find typical open source rails project that i can download
and learn from ?
i'm interested in facebook connect integration (facebooker), tag clouds, searching in
my website
I'm not looking not tutorials or screen casts
Thanks!
This question gives a good list
a list of projects with good test-suites
a list of open source rails apps to learn from
Have a browse of ruby tool box and download some open source. For example there's refinery and zena, two content management systems and Rboard, a forum. Depends what you want really but there's plenty out there. Ruby toolbox entries are ordered by github watchers and forks to give you an idea of their popularity.
I really like looking at the commits in teambox.
I find it a bit more complicated. But there's also spree.
There's also devise which is really interesting to look at too.
Finally, I'd recommend you to follow the rails commits (it's the only commits feed I have in my Google Reader).
Gady, this is an extremely rich topic you're asking about and resources are all over the internet. Try starting at http://rubyonrails.org/.
You should be able to find tens of questions just like yours (asked and answered) by searching SO at the top bar.
For Rails, part of it is the building process, so one feasible approach is to read a tutorial like http://railstutorial.org/book
then when in Chapter 2, you will use Scaffold, and at that time, you will have some basic code to look into how a basic Rails app is.
I also suggest you use source control like Git, Mercurial, or SVN to commit different phases of the project, from creating the rails project and then after each step, so you can diff what the changes are during each step.
If you already have Ruby 1.9.2, Rails 3.0.1, and sqlite3, then you can
rails new myproj
cd myproj
rails generate scaffold foo name:string salary:integer gpa:float note:text
rake db:migrate
rails server
and now you can use http://localhost:3000/foos to create, display, update, delete the foo records, and have quite a bit of source code to look at. Most of the customizable code is in app, with css and javascript in the public folder.
Ryan Bates has an excellent series of videos.

An extremely valuable resource.
Radiant is a CMS that you can download for free and see how it works. It is a great piece of code to look at and see how it works.
I guess that most open source Rails projects are shared on Github, so it may be interesting to browse its Ruby section and look for most watched or most forked projects:
http://github.com/languages/Ruby
Steady stream of new interesting projects to take a look at :)
And don't forget the official:
guides.rubyonrails.org
well there is one "bigger" project on github, waiting for downloading and contribution...
but it's a little controversial because of the security issued they have (had?)
It's still worth a look:

I'm learning ruby on rails on a linux box and dusting off my VIM skills (skillz?).
When I got started on VIM way back in my c++ days, I had a friend with a great vimfiles folder that had tons of stuff to get started. Starting from scratch, vim is great, but it feels like it could be a lot better.
I currently have:
vim-ruby
buffer explorer
xml-edit (though I don't have it currently working with erb files)
I know that barely scratches the surface of what some more experienced vim/ruby devs have (including the one offs in the vim.rc file).
Is there a list somewhere (or could we create one) of a bunch of the standard vim configurations needed to make programming ruby (and rails) more fun? Is there a zip/tarball somewhere with a good base setup?
take a look at tim pope's repos on git hub. Many, many awesome vim plugins and extensions for working with ruby and rails
http://github.com/tpope
snipMate (GitHub repo) is highly recommended. It enables you to use TextMate-style snippets in Vim.
snipMate is not Ruby-specific: by default, it comes with one file containing Ruby-specific snippets. If you are going to work a lot on Ruby-based code (Rails, RSpec, Shoulda, and the like), it's probably better to use one of the available snippets' collections and customize it as you see fit rather than writing your own snippets from scratch.
There is a pretty nice setup for your VIM environment.
http://github.com/akitaonrails/vimfiles
Just follow the instructions and in a minute or two you will have everything ready for Ruby(on Rails) development.
As Jed has mentioned above - tpope plugin is a "must have" and it is part of the akita vimfiles.
I have this in my ~/.vimrc to quickly see the output of a file I'm working on:
map <Leader>r :w! <bar> !ruby %<CR>
For rails, two essential plugins are rails.vim and the NERD tree, for navigating the directory of the rails project you're working on.
