rool/rails/hub/trunk/README:

prev.	current
1		== Welcome to Rails
	1	== Welcome to Hub
3		Rails is a web-application and persistence framework that includes everything
4		needed to create database-backed web-applications according to the
5		Model-View-Control pattern of separation. This pattern splits the view (also
6		called the presentation) into "dumb" templates that are primarily responsible
7		for inserting pre-built data in between HTML tags. The model contains the
8		"smart" domain objects (such as Account, Product, Person, Post) that holds all
9		the business logic and knows how to persist themselves to a database. The
10		controller handles the incoming requests (such as Save New Account, Update
11		Product, Show Post) by manipulating the model and directing data to the view.
13		In Rails, the model is handled by what's called an object-relational mapping
14		layer entitled Active Record. This layer allows you to present the data from
15		database rows as objects and embellish these data objects with business logic
16		methods. You can read more about Active Record in
17		link:files/vendor/rails/activerecord/README.html.
	4	Hub is a single sign-on solution for multiple Ruby On Rails applications which
	5	are running under the same domain but different paths within that domain. When
	6	a user signs into Hub, they don't have to individually sign in to other
	7	applications on the domain provided that those applications are integrated
	8	with the Hub mechanism. This requires software development effort on behalf of
	9	the application installer or application developer.
19		The controller and view are handled by the Action Pack, which handles both
20		layers by its two parts: Action View and Action Controller. These two layers
21		are bundled in a single package due to their heavy interdependence. This is
22		unlike the relationship between the Active Record and Action Pack that is much
23		more separate. Each of these packages can be used independently outside of
24		Rails. You can read more about Action Pack in
25		link:files/vendor/rails/actionpack/README.html.
	11	Hub provides a solution to a different problem from that addressed by cross
	12	domain single sign-on solutions such as OpenID, wherein a user will typically
	13	have to sign in to domain individually, but is at least able to do so using a
	14	single set of identifying credentials.
28		== Getting started
	17	=== Further reading
30		1. Start the web server: <tt>ruby script/server</tt> (run with --help for options)
31		2. Go to http://localhost:3000/ and get "Welcome aboard: You’re riding the Rails!"
32		3. Follow the guidelines to start developing your application
	19	For more information about Hub, please see:
	21	* http://hub.pond.org.uk/
35		== Web servers
	23	For more information about Ruby On Rails, please see:
37		Rails uses the built-in web server in Ruby called WEBrick by default, so you don't
38		have to install or configure anything to play around.
	25	* http://www.rubyonrails.org/
40		If you have lighttpd installed, though, it'll be used instead when running script/server.
41		It's considerably faster than WEBrick and suited for production use, but requires additional
42		installation and currently only works well on OS X/Unix (Windows users are encouraged
43		to start with WEBrick). We recommend version 1.4.11 and higher. You can download it from
44		http://www.lighttpd.net.
	27	For more software from Hipposoft, please visit:
46		If you want something that's halfway between WEBrick and lighttpd, we heartily recommend
47		Mongrel. It's a Ruby-based web server with a C-component (so it requires compilation) that
48		also works very well with Windows. See more at http://mongrel.rubyforge.org/.
49
50		But of course its also possible to run Rails with the premiere open source web server Apache.
51		To get decent performance, though, you'll need to install FastCGI. For Apache 1.3, you want
52		to use mod_fastcgi. For Apache 2.0+, you want to use mod_fcgid.
53
54		See http://wiki.rubyonrails.com/rails/pages/FastCGI for more information on FastCGI.
55
56		== Example for Apache conf
57
58		<VirtualHost *:80>
59		ServerName rails
60		DocumentRoot /path/application/public/
61		ErrorLog /path/application/log/server.log
62
63		<Directory /path/application/public/>
64		Options ExecCGI FollowSymLinks
65		AllowOverride all
66		Allow from all
67		Order allow,deny
68		</Directory>
69		</VirtualHost>
70
71		NOTE: Be sure that CGIs can be executed in that directory as well. So ExecCGI
72		should be on and ".cgi" should respond. All requests from 127.0.0.1 go
73		through CGI, so no Apache restart is necessary for changes. All other requests
74		go through FCGI (or mod_ruby), which requires a restart to show changes.
75
76
77		== Debugging Rails
78
79		Have "tail -f" commands running on both the server.log, production.log, and
80		test.log files. Rails will automatically display debugging and runtime
81		information to these files. Debugging info will also be shown in the browser
82		on requests from 127.0.0.1.
83
84
85		== Breakpoints
86
87		Breakpoint support is available through the script/breakpointer client. This
88		means that you can break out of execution at any point in the code, investigate
89		and change the model, AND then resume execution! Example:
90
91		class WeblogController < ActionController::Base
92		def index
93		@posts = Post.find_all
94		breakpoint "Breaking out from the list"
95		end
96		end
97
98		So the controller will accept the action, run the first line, then present you
99		with a IRB prompt in the breakpointer window. Here you can do things like:
100
101		Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint'
102
103		>> @posts.inspect
104		=> "[#<Post:0x14a6be8 @attributes={\"title\"=>nil, \"body\"=>nil, \"id\"=>\"1\"}>,
105		#<Post:0x14a6620 @attributes={\"title\"=>\"Rails you know!\", \"body\"=>\"Only ten..\", \"id\"=>\"2\"}>]"
106		>> @posts.first.title = "hello from a breakpoint"
107		=> "hello from a breakpoint"
108
109		...and even better is that you can examine how your runtime objects actually work:
110
111		>> f = @posts.first
112		=> #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>
113		>> f.
114		Display all 152 possibilities? (y or n)
115
116		Finally, when you're ready to resume execution, you press CTRL-D
117
118
119		== Console
120
121		You can interact with the domain model by starting the console through script/console.
122		Here you'll have all parts of the application configured, just like it is when the
123		application is running. You can inspect domain models, change values, and save to the
124		database. Starting the script without arguments will launch it in the development environment.
125		Passing an argument will specify a different environment, like <tt>script/console production</tt>.
126
127		To reload your controllers and models after launching the console run <tt>reload!</tt>
128
129
130
131		== Description of contents
132
133		app
134		Holds all the code that's specific to this particular application.
135
136		app/controllers

138		automated URL mapping. All controllers should descend from
139		ActionController::Base.
140
141		app/models
142		Holds models that should be named like post.rb.
143		Most models will descend from ActiveRecord::Base.
144
145		app/views
146		Holds the template files for the view that should be named like
147		weblog/index.rhtml for the WeblogController#index action. All views use eRuby
148		syntax. This directory can also be used to keep stylesheets, images, and so on
149		that can be symlinked to public.
150
151		app/helpers
152		Holds view helpers that should be named like weblog_helper.rb.
153
154		app/apis
155		Holds API classes for web services.

157		config
158		Configuration files for the Rails environment, the routing map, the database, and other dependencies.
159
160		components
161		Self-contained mini-applications that can bundle together controllers, models, and views.
162
163		db
164		Contains the database schema in schema.rb. db/migrate contains all
165		the sequence of Migrations for your schema.
166
167		lib
168		Application specific libraries. Basically, any kind of custom code that doesn't
169		belong under controllers, models, or helpers. This directory is in the load path.
170
171		public
172		The directory available for the web server. Contains subdirectories for images, stylesheets,
173		and javascripts. Also contains the dispatchers and the default HTML files.
174
175		script
176		Helper scripts for automation and generation.
177
178		test
179		Unit and functional tests along with fixtures.
180

	2	Hub consists of this Ruby On Rails application for managing user accounts
	3	including the sign-up and sign-in process, a DRb server which remembers which
	4	users are logged in at run-time and provides this information over a Unix
	5	domain socket to other Hub-integrated applications, and a gem which provides
	6	library facilities which make it easy to talk to the DRb server.
