README ¶ +6 -178

@@ -1,182 +1,10
1	- == Welcome to Rails	1	+ == cafe grader
2	-
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.
12	-
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.
18	-
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.
26	-
27	-
28	- == Getting started
29	-
30	- 1. At the command prompt, start a new rails application using the rails command
31	- and your application name. Ex: rails myapp
32	- (If you've downloaded rails in a complete tgz or zip, this step is already done)
33	- 2. Change directory into myapp and start the web server: <tt>script/server</tt> (run with --help for options)
34	- 3. Go to http://localhost:3000/ and get "Welcome aboard: You’re riding the Rails!"
35	- 4. Follow the guidelines to start developing your application
36	-
37	-
38	- == Web Servers
39	-
40	- By default, Rails will try to use Mongrel and lighttpd if they are installed, otherwise
41	- Rails will use the WEBrick, the webserver that ships with Ruby. When you run script/server,
42	- Rails will check if Mongrel exists, then lighttpd and finally fall back to WEBrick. This ensures
43	- that you can always get up and running quickly.
44		2
45	- Mongrel is a Ruby-based webserver with a C-component (which requires compilation) that is	3	+ cafe grader is a programming contest platform used in Thailand IOI training.
46	- suitable for development and deployment of Rails applications. If you have Ruby Gems installed,	4	+ The package includes 2 repositories, jittat/cafe-grader-web and jittat/cafe-grader-judge-scripts.
47	- getting up and running with mongrel is as easy as: <tt>gem install mongrel</tt>.
48	- More info at: http://mongrel.rubyforge.org
49	-
50	- If Mongrel is not installed, Rails will look for lighttpd. It's considerably faster than
51	- Mongrel and WEBrick and also suited for production use, but requires additional
52	- installation and currently only works well on OS X/Unix (Windows users are encouraged
53	- to start with Mongrel). We recommend version 1.4.11 and higher. You can download it from
54	- http://www.lighttpd.net.
55	-
56	- And finally, if neither Mongrel or lighttpd are installed, Rails will use the built-in Ruby
57	- web server, WEBrick. WEBrick is a small Ruby web server suitable for development, but not
58	- for production.
59	-
60	- But of course its also possible to run Rails on any platform that supports FCGI.
61	- Apache, LiteSpeed, IIS are just a few. For more information on FCGI,
62	- please visit: http://wiki.rubyonrails.com/rails/pages/FastCGI
63	-
64	-
65	- == Debugging Rails
66	-
67	- Have "tail -f" commands running on the server.log and development.log. Rails will
68	- automatically display debugging and runtime information to these files. Debugging
69	- info will also be shown in the browser on requests from 127.0.0.1.
70	-
71	-
72	- == Breakpoints
73	-
74	- Breakpoint support is available through the script/breakpointer client. This
75	- means that you can break out of execution at any point in the code, investigate
76	- and change the model, AND then resume execution! Example:
77	-
78	- class WeblogController < ActionController::Base
79	- def index
80	- @posts = Post.find(:all)
81	- breakpoint "Breaking out from the list"
82	- end
83	- end
84	-
85	- So the controller will accept the action, run the first line, then present you
86	- with a IRB prompt in the breakpointer window. Here you can do things like:
87	-
88	- Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint'
89		5
90	- >> @posts.inspect	6	+ === Installation
91	- => "[#<Post:0x14a6be8 @attributes={\"title\"=>nil, \"body\"=>nil, \"id\"=>\"1\"}>,
92	- #<Post:0x14a6620 @attributes={\"title\"=>\"Rails you know!\", \"body\"=>\"Only ten..\", \"id\"=>\"2\"}>]"
93	- >> @posts.first.title = "hello from a breakpoint"
94	- => "hello from a breakpoint"
95	-
96	- ...and even better is that you can examine how your runtime objects actually work:
97	-
98	- >> f = @posts.first
99	- => #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>
100	- >> f.
101	- Display all 152 possibilities? (y or n)
102	-
103	- Finally, when you're ready to resume execution, you press CTRL-D
104	-
105	-
106	- == Console
107	-
108	- You can interact with the domain model by starting the console through <tt>script/console</tt>.
109	- Here you'll have all parts of the application configured, just like it is when the
110	- application is running. You can inspect domain models, change values, and save to the
111	- database. Starting the script without arguments will launch it in the development environment.
112	- Passing an argument will specify a different environment, like <tt>script/console production</tt>.
113	-
114	- To reload your controllers and models after launching the console run <tt>reload!</tt>
115	-
116	- To reload your controllers and models after launching the console run <tt>reload!</tt>

135	- Holds the template files for the view that should be named like	9	+ cafe-grader-judge-scripts/installer/install.sh . See http://theory.cpe.ku.ac.th/wiki/index.php/%E0%B8%81%E0%B8%B2%E0%B8%A3%E0%B8%95%E0%B8%B4%E0%B8%94%E0%B8%95%E0%B8%B1%E0%B9%89%E0%B8%87_Cafe_grader for the detail.
136	- weblogs/index.rhtml for the WeblogsController#index action. All views use eRuby
137	- syntax.
138	-
139	- app/views/layouts
140	- Holds the template files for layouts to be used with views. This models the common
141	- header/footer method of wrapping views. In your views, define a layout using the
142	- <tt>layout :default</tt> and create a file named default.rhtml. Inside default.rhtml,
143	- call <% yield %> to render the view using this layout.
144	-
145	- app/helpers
146	- Holds view helpers that should be named like weblogs_helper.rb. These are generated
147	- for you automatically when using script/generate for controllers. Helpers can be used to
148	- wrap functionality for your views into methods.
149	-
150	- config
151	- Configuration files for the Rails environment, the routing map, the database, and other dependencies.
152	-
153	- components
154	- Self-contained mini-applications that can bundle together controllers, models, and views.
155		10
156	- db
157	- Contains the database schema in schema.rb. db/migrate contains all
158	- the sequence of Migrations for your schema.
159	-
160	- doc
161	- This directory is where your application documentation will be stored when generated
162	- using <tt>rake doc:app</tt>
163	-
164	- lib
165	- Application specific libraries. Basically, any kind of custom code that doesn't
166	- belong under controllers, models, or helpers. This directory is in the load path.
167	-
168	- public
169	- The directory available for the web server. Contains subdirectories for images, stylesheets,
170	- and javascripts. Also contains the dispatchers and the default HTML files. This should be
171	- set as the DOCUMENT_ROOT of your web server.
172	-
173	- script
174	- Helper scripts for automation and generation.
175	-
176	- test
177	- Unit and functional tests along with fixtures. When using the script/generate scripts, template
178	- test files will be generated for you and placed in this directory.
179	-
180	- vendor
181	- External libraries that the application depends on. Also includes the plugins subdirectory.
182	- This directory is in the load path.
