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, start a new rails application using the rails command + and your application name. Ex: rails myapp + (If you've downloaded rails in a complete tgz or zip, this step is already done) +2. Change directory into myapp and start the web server: script/server (run with --help for options) +3. Go to http://localhost:3000/ and get "Welcome aboard: You’re riding the Rails!" +4. Follow the guidelines to start developing your application + + +== Web Servers + +By default, Rails will try to use Mongrel and lighttpd if they are installed, otherwise +Rails will use the WEBrick, the webserver that ships with Ruby. When you run script/server, +Rails will check if Mongrel exists, then lighttpd and finally fall back to WEBrick. This ensures +that you can always get up and running quickly. + +Mongrel is a Ruby-based webserver with a C-component (which requires compilation) that is +suitable for development and deployment of Rails applications. If you have Ruby Gems installed, +getting up and running with mongrel is as easy as: gem install mongrel. +More info at: http://mongrel.rubyforge.org + +If Mongrel is not installed, Rails will look for lighttpd. It's considerably faster than +Mongrel and WEBrick and also suited for production use, but requires additional +installation and currently only works well on OS X/Unix (Windows users are encouraged +to start with Mongrel). We recommend version 1.4.11 and higher. You can download it from +http://www.lighttpd.net. + +And finally, if neither Mongrel or lighttpd are installed, Rails will use the built-in Ruby +web server, WEBrick. WEBrick is a small Ruby web server suitable for development, but not +for production. + +But of course its also possible to run Rails on any platform that supports FCGI. +Apache, LiteSpeed, IIS are just a few. For more information on FCGI, +please visit: http://wiki.rubyonrails.com/rails/pages/FastCGI + + +== 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/ including: + +* The Learning Ruby (Pickaxe) Book: http://www.ruby-doc.org/docs/ProgrammingRuby/ +* Learn to Program: http://pine.fm/LearnToProgram/ (a beginners guide) + +These two online (and free) books will bring you up to speed on the Ruby language +and also on programming in general. + + +== Breakpoints + +Breakpoint support is available through the script/breakpointer client. This +means that you can break out of execution at any point in the code, investigate +and change the model, AND then resume execution! Example: + + class WeblogController < ActionController::Base + def index + @posts = Post.find(:all) + breakpoint "Breaking out from the list" + end + end + +So the controller will accept the action, run the first line, then present you +with a IRB prompt in the breakpointer window. Here you can do things like: + +Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint' + + >> @posts.inspect + => "[#nil, \"body\"=>nil, \"id\"=>\"1\"}>, + #\"Rails you know!\", \"body\"=>\"Only ten..\", \"id\"=>\"2\"}>]" + >> @posts.first.title = "hello from a breakpoint" + => "hello from a breakpoint" + +...and even better is that you can examine how your runtime objects actually work: + + >> f = @posts.first + => #nil, "body"=>nil, "id"=>"1"}> + >> f. + Display all 152 possibilities? (y or n) + +Finally, when you're ready to resume execution, you press CTRL-D + + +== Console + +You can interact with the domain model by starting the console through script/console. +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. +Passing an argument will specify a different environment, like script/console production. + +To reload your controllers and models after launching the console run reload! + +To reload your controllers and models after launching the console run reload! + + + +== Description of contents + +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.

In your views, define a layout using the + layout :default and create a file named default.rhtml. Inside default.rhtml, + 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 script/generate 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. + +components + Self-contained mini-applications that can bundle together controllers, models, and views. + +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 rake doc:app + +lib + Application specific libraries.

Getting started

+

Here’s how to get rolling:

+ +
    +
  1. +

    Create your databases and edit config/database.yml

    +

    Rails needs to know your login and password.

    +
    2. + +
  2. +

    Use script/generate to create your models and controllers

    +

    To see all available options, run it without parameters.

    +
    3. + +
  3. +

    Set up a default route and remove or rename this file

    +

    Routes are setup in config/routes.rb.

    +
