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"
|
To use:
|
||||||
templates that are primarily responsible for inserting pre-built data in between
|
* Load into a Rails 3 environment
|
||||||
HTML tags. The model contains the "smart" domain objects (such as Account,
|
* Rename config/config.yml.example to config/config.yml and edit appropriately
|
||||||
Product, Person, Post) that holds all the business logic and knows how to
|
* Use the Rails console to create a new User and set user.admin = true
|
||||||
persist themselves to a database. The controller handles the incoming requests
|
* Run bundle install, rake db:migrate, etc.
|
||||||
(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.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>
|
|
||||||

||||||

|
|
||||||

|
|
||||||
|
|
||||||
|
|
||||||
== 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/assets
|
|
||||||
Contains subdirectories for images, stylesheets, and JavaScript files.
|
|
||||||
|
|
||||||
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. 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.
