|

== 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. At the command prompt, create a new Rails application:
|
||||
<tt>rails new myapp</tt> (where <tt>myapp</tt> is the application name)
|
||||
|
||||
2. Change directory to <tt>myapp</tt> and start the web server:
|
||||
<tt>cd myapp; rails server</tt> (run with --help for options)
|
||||
|
||||
3. Go to http://localhost:3000/ and you'll see:
|
||||
"Welcome aboard: You're riding Ruby on Rails!"
|
||||
|
||||
4. Follow the guidelines to start developing your application. You can find
|
||||
the following resources handy:
|
||||
|
||||
* The Getting Started Guide: http://guides.rubyonrails.org/getting_started.html
|
||||
* Ruby on Rails Tutorial Book: http://www.railstutorial.org/
|
||||
|
||||
|
||||
== Debugging Rails
|
||||
|
||||
Sometimes your application goes wrong. Fortunately there are a lot of tools that
|
||||
will help you debug it and get it back on the rails.
|
||||
|
||||
First area to check is the application log files. Have "tail -f" commands
|
||||
running on the server.log and development.log. Rails will automatically display
|
||||
debugging and runtime information to these files. Debugging info will also be
|
||||
shown in the browser on requests from 127.0.0.1.
|
||||
|
||||
You can also log your own messages directly into the log file from your code
|
||||
using the Ruby logger class from inside your controllers. Example:
|
||||
|
||||
class WeblogController < ActionController::Base
|
||||
def destroy
|
||||
@weblog = Weblog.find(params[:id])
|
||||
@weblog.destroy
|
||||
logger.info("#{Time.now} Destroyed Weblog ID ##{@weblog.id}!")
|
||||
end
|
||||
end
|
||||
|
||||
The result will be a message in your log file along the lines of:
|
||||
|
||||
Mon Oct 08 14:22:29 +1000 2007 Destroyed Weblog ID #1!
|
||||
|
||||
More information on how to use the logger is at http://www.ruby-doc.org/core/
|
||||
|
||||
Also, Ruby documentation can be found at http://www.ruby-lang.org/. There are
|
||||
several books available online as well:
|
||||
|
||||
* Programming Ruby: http://www.ruby-doc.org/docs/ProgrammingRuby/ (Pickaxe)
|
||||
* Learn to Program: http://pine.fm/LearnToProgram/ (a beginners guide)
|
||||
|
||||
These two books will bring you up to speed on the Ruby language and also on
|
||||
programming in general.
|
||||
|
||||
|
||||
== Debugger
|
||||
|
||||
Debugger support is available through the debugger command when you start your
|
||||
Mongrel or WEBrick server with --debugger. This means that you can break out of
|
||||
execution at any point in the code, investigate and change the model, and then,
|
||||
resume execution! You need to install ruby-debug to run the server in debugging
|
||||
mode. With gems, use <tt>sudo gem install ruby-debug</tt>. Example:
|
||||
|
||||
class WeblogController < ActionController::Base
|
||||
def index
|
||||
@posts = Post.find(:all)
|
||||
debugger
|
||||
end
|
||||
end
|
||||
|
||||
So the controller will accept the action, run the first line, then present you
|
||||
with a IRB prompt in the server window. Here you can do things like:
|
||||
|
||||
>> @posts.inspect
|
||||
=> "[#<Post:0x14a6be8
|
||||
@attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>,
|
||||
#<Post:0x14a6620
|
||||
@attributes={"title"=>"Rails", "body"=>"Only ten..", "id"=>"2"}>]"
|
||||
>> @posts.first.title = "hello from a debugger"
|
||||
=> "hello from a debugger"
|
||||
|
||||
...and even better, you can examine how your runtime objects actually work:
|
||||
|
||||
>> f = @posts.first
|
||||
=> #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>
|
||||
>> f.
|
||||
Display all 152 possibilities? (y or n)
|
||||
|
||||
Finally, when you're ready to resume execution, you can enter "cont".
|
||||
|
||||
|
||||
== Console
|
||||
|
||||
The console is a Ruby shell, which allows you to interact with your
|
||||
application's domain model. Here you'll have all parts of the application
|
||||
configured, just like it is when the application is running. You can inspect
|
||||
domain models, change values, and save to the database. Starting the script
|
||||
without arguments will launch it in the development environment.
|
||||
|
||||
To start the console, run <tt>rails console</tt> from the application
|
||||
directory.
|
||||
|
||||
Options:
|
||||
|
||||
* Passing the <tt>-s, --sandbox</tt> argument will rollback any modifications
|
||||
made to the database.
|
||||
* Passing an environment name as an argument will load the corresponding
|
||||
environment. Example: <tt>rails console production</tt>.
|
||||
|
||||
To reload your controllers and models after launching the console run
|
||||
<tt>reload!</tt>
|
||||
|
||||
More information about irb can be found at:
|
||||
link:http://www.rubycentral.com/pickaxe/irb.html
|
||||
|
||||
|
||||
== dbconsole
|
||||
|
||||
You can go to the command line of your database directly through <tt>rails
|
||||
dbconsole</tt>. You would be connected to the database with the credentials
|
||||
defined in database.yml. Starting the script without arguments will connect you
|
||||
to the development database. Passing an argument will connect you to a different
|
||||
database, like <tt>rails dbconsole production</tt>. Currently works for MySQL,
|
||||
PostgreSQL and SQLite 3.

|
||||
app
|
||||
Holds all the code that's specific to this particular application.
|
||||
|
||||
app/controllers
|
||||
Holds controllers that should be named like weblogs_controller.rb for
|
||||
automated URL mapping. All controllers should descend from
|
||||
ApplicationController which itself descends from ActionController::Base.
|
||||
|
||||
app/models
|
||||
Holds models that should be named like post.rb. Models descend from
|
||||
ActiveRecord::Base by default.
|
||||
|
||||
app/views
|
||||
Holds the template files for the view that should be named like
|
||||
weblogs/index.html.erb for the WeblogsController#index action. All views use
|
||||
eRuby syntax by default.
|
||||
|
||||
app/views/layouts
|
||||
Holds the template files for layouts to be used with views. This models the
|
||||
common header/footer method of wrapping views. In your views, define a layout
|
||||
using the <tt>layout :default</tt> and create a file named default.html.erb.
|
||||
Inside default.html.erb, call <% yield %> to render the view using this
|
||||
layout.
|
||||
|
||||
app/helpers
|
||||
Holds view helpers that should be named like weblogs_helper.rb. These are
|
||||
generated for you automatically when using generators for controllers.
|
||||
Helpers can be used to wrap functionality for your views into methods.
|
||||
|
||||
config
|
||||
Configuration files for the Rails environment, the routing map, the database,
|
||||
and other dependencies.
|
||||
|
||||
db
|
||||
Contains the database schema in schema.rb. db/migrate contains all the
|
||||
sequence of Migrations for your schema.
|
||||
|
||||
doc
|
||||
This directory is where your application documentation will be stored when
|
||||
generated using <tt>rake doc:app</tt>
|
||||
|
||||
lib
|
||||
Application specific libraries. Basically, any kind of custom code that
|
||||
doesn't belong under controllers, models, or helpers. This directory is in
|
||||
the load path.
|
||||
|
||||
public
|
||||
The directory available for the web server. Contains subdirectories for
|
||||
images, stylesheets, and javascripts. Also contains the dispatchers and the
|
||||
default HTML files. This should be set as the DOCUMENT_ROOT of your web
|
||||
server.
|
||||
|
||||
script
|
||||
Helper scripts for automation and generation.
|
||||
|
||||
test
|
||||
Unit and functional tests along with fixtures. When using the rails generate
|
||||
command, template test files will be generated for you and placed in this
|
||||
directory.
|
||||
|
||||
vendor
|
||||
External libraries that the application depends on. Also includes the plugins
|
||||
subdirectory. If the app has frozen rails, those gems also go here, under
|
||||
vendor/rails/. This directory is in the load path.
