== 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
|
||
|
|
link:files/vendor/rails/activerecord/README.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
|
||
|
|
link:files/vendor/rails/actionpack/README.html.

== Getting Started
|
||
|
|
|
||
|
|
1. Install Rails at the command prompt if you haven't yet:
|
||
|
|
<tt>gem install rails</tt>
|
||
|
|
|
||
|
|
2. At the command prompt, create a new Rails application:
|
||
|
|
<tt>rails new myapp</tt> (where <tt>myapp</tt> is the application name)
|
||
|
|
|
||
|
|
3. Change directory to <tt>myapp</tt> and start the web server:
|
||
|
|
<tt>cd myapp; rails server</tt> (run with --help 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 can find
|
||
|
|
the following resources handy:
