RDoc autolinks the word "Rails" to the doc page for the Rails module. But README.rdoc is displayed in the home page at GitHub and the slashes are visible there, which is weird. We leave by now the slashes off in the file, and generate a second file for the API with them.

== Welcome to Rails
|
|
|
|
Rails is a web-application framework that includes everything needed to create
|
|
database-backed web applications according to the Model-View-Control pattern.
|
|
|
|
This pattern splits the view (also called the presentation) into "dumb"
|
|
templates that are primarily responsible for inserting pre-built data in between
|
|
HTML tags. The model contains the "smart" domain objects (such as Account,
|
|
Product, Person, Post) that holds all the business logic and knows how to
|
|
persist themselves to a database. The controller handles the incoming requests
|
|
(such as Save New Account, Update Product, Show Post) by manipulating the model
|
|
and directing data to the view.
|
|
|
|
In Rails, the model is handled by what's called an object-relational mapping
|
|
layer entitled Active Record. This layer allows you to present the data from
|
|
database rows as objects and embellish these data objects with business logic
|
|
methods. You can read more about Active Record in its
|
|
{README}[link:files/activerecord/README_rdoc.html].
|
|
|
|
The controller and view are handled by the Action Pack, which handles both
|
|
layers by its two parts: Action View and Action Controller. These two layers
|
|
are bundled in a single package due to their heavy interdependence. This is
|
|
unlike the relationship between the Active Record and Action Pack that is much
|
|
more separate. Each of these packages can be used independently outside of
|
|
Rails. You can read more about Action Pack in its
|
|
{README}[link:files/actionpack/README_rdoc.html].

== Getting Started
|
|
|
|
1. Install Rails at the command prompt if you haven't yet:
|
|
|
|
gem install rails
|
|
|
|
2. At the command prompt, create a new Rails application:
|
|
|
|
rails new myapp
|
|
|
|
where "myapp" is the application name.
|
|
|
|
3. Change directory to +myapp+ and start the web server:
|
|
|
|
cd myapp; rails server
|
|
|
|
Run with <tt>--help</tt> for options.
|
|
|
|
4. Go to http://localhost:3000/ and you'll see:
|
|
|
|
"Welcome aboard: You're riding Ruby on Rails!"
|
|
|
|
5. Follow the guidelines to start developing your application. You may find the following resources handy:
|
|
|
|
* The README file created within your application.
|
|
* The {Getting Started with Rails}[http://guides.rubyonrails.org/getting_started.html].
|
|
* The {Ruby on Rails Tutorial}[http://railstutorial.org/book].
|
|
* The {Ruby on Rails Guides}[http://guides.rubyonrails.org].
|
|
* The {API Documentation}[http://api.rubyonrails.org].
