0
+== Welcome to Rails
0
+
0
+Rails is a web-application and persistence framework that includes everything
0
+needed to create database-backed web-applications according to the
0
+Model-View-Control pattern of separation. This pattern splits the view (also
0
+called the presentation) into "dumb" templates that are primarily responsible
0
+for inserting pre-built data in between HTML tags. The model contains the
0
+"smart" domain objects (such as Account, Product, Person, Post) that holds all
0
+the business logic and knows how to persist themselves to a database. The
0
+controller handles the incoming requests (such as Save New Account, Update
0
+Product, Show Post) by manipulating the model and directing data to the view.
0
+
0
+In Rails, the model is handled by what's called an object-relational mapping
0
+layer entitled Active Record. This layer allows you to present the data from
0
+database rows as objects and embellish these data objects with business logic
0
+methods. You can read more about Active Record in
0
+link:files/vendor/rails/activerecord/README.html.
0
+
0
+The controller and view are handled by the Action Pack, which handles both
0
+layers by its two parts: Action View and Action Controller. These two layers
0
+are bundled in a single package due to their heavy interdependence. This is
0
+unlike the relationship between the Active Record and Action Pack that is much
0
+more separate. Each of these packages can be used independently outside of
0
+Rails. You can read more about Action Pack in
0
+link:files/vendor/rails/actionpack/README.html.
0
+
0
+
0
+== Getting started
0
+
0
+1. Start the web server: <tt>ruby script/server</tt> (run with --help for options)
0
+2. Go to http://localhost:3000/ and get "Welcome aboard: You’re riding the Rails!"
0
+3. Follow the guidelines to start developing your application
0
+
0
+
0
+== Web servers
0
+
0
+Rails uses the built-in web server in Ruby called WEBrick by default, so you don't
0
+have to install or configure anything to play around.
0
+
0
+If you have lighttpd installed, though, it'll be used instead when running script/server.
0
+It's considerably faster than WEBrick and suited for production use, but requires additional
0
+installation and currently only works well on OS X/Unix (Windows users are encouraged
0
+to start with WEBrick). We recommend version 1.4.11 and higher. You can download it from
0
+http://www.lighttpd.net.
0
+
0
+If you want something that's halfway between WEBrick and lighttpd, we heartily recommend
0
+Mongrel. It's a Ruby-based web server with a C-component (so it requires compilation) that
0
+also works very well with Windows. See more at http://mongrel.rubyforge.org/.
0
+
0
+But of course its also possible to run Rails with the premiere open source web server Apache.
0
+To get decent performance, though, you'll need to install FastCGI. For Apache 1.3, you want
0
+to use mod_fastcgi. For Apache 2.0+, you want to use mod_fcgid.
0
+
0
+See http://wiki.rubyonrails.com/rails/pages/FastCGI for more information on FastCGI.
0
+
0
+== Example for Apache conf
0
+
0
+ <VirtualHost *:80>
0
+ ServerName rails
0
+ DocumentRoot /path/application/public/
0
+ ErrorLog /path/application/log/server.log
0
+
0
+ <Directory /path/application/public/>
0
+ Options ExecCGI FollowSymLinks
0
+ AllowOverride all
0
+ Allow from all
0
+ Order allow,deny
0
+ </Directory>
0
+ </VirtualHost>
0
+
0
+NOTE: Be sure that CGIs can be executed in that directory as well. So ExecCGI
0
+should be on and ".cgi" should respond. All requests from 127.0.0.1 go
0
+through CGI, so no Apache restart is necessary for changes. All other requests
0
+go through FCGI (or mod_ruby), which requires a restart to show changes.
0
+
0
+
0
+== Debugging Rails
0
+
0
+Have "tail -f" commands running on both the server.log, production.log, and
0
+test.log files. Rails will automatically display debugging and runtime
0
+information to these files. Debugging info will also be shown in the browser
0
+on requests from 127.0.0.1.
0
+
0
+
0
+== Breakpoints
0
+
0
+Breakpoint support is available through the script/breakpointer client. This
0
+means that you can break out of execution at any point in the code, investigate
0
+and change the model, AND then resume execution! Example:
0
+
0
+ class WeblogController < ActionController::Base
0
+ def index
0
+ @posts = Post.find_all
0
+ breakpoint "Breaking out from the list"
0
+ end
0
+ end
0
+
0
+So the controller will accept the action, run the first line, then present you
0
+with a IRB prompt in the breakpointer window. Here you can do things like:
0
+
0
+Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint'
0
+
0
+ >> @posts.inspect
0
+ => "[#<Post:0x14a6be8 @attributes={\"title\"=>nil, \"body\"=>nil, \"id\"=>\"1\"}>,
0
+ #<Post:0x14a6620 @attributes={\"title\"=>\"Rails you know!\", \"body\"=>\"Only ten..\", \"id\"=>\"2\"}>]"
0
+ >> @posts.first.title = "hello from a breakpoint"
0
+ => "hello from a breakpoint"
0
+
0
+...and even better is that you can examine how your runtime objects actually work:
0
+
0
+ >> f = @posts.first
0
+ => #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>
0
+ >> f.
0
+ Display all 152 possibilities? (y or n)
0
+
0
+Finally, when you're ready to resume execution, you press CTRL-D
0
+
0
+
0
+== Console
0
+
0
+You can interact with the domain model by starting the console through script/console.
0
+Here you'll have all parts of the application configured, just like it is when the
0
+application is running. You can inspect domain models, change values, and save to the
0
+database. Starting the script without arguments will launch it in the development environment.
0
+Passing an argument will specify a different environment, like <tt>script/console production</tt>.
0
+
0
+To reload your controllers and models after launching the console run <tt>reload!</tt>
0
+
0
+
0
+
