== Welcome to Rails
2+
3+
Rails is a web-application framework that includes everything needed to create
4+
database-backed web applications according to the Model-View-Control pattern.
5+
6+
This pattern splits the view (also called the presentation) into "dumb"
7+
templates that are primarily responsible for inserting pre-built data in between
8+
HTML tags. The model contains the "smart" domain objects (such as Account,
9+
Product, Person, Post) that holds all the business logic and knows how to
10+
persist themselves to a database. The controller handles the incoming requests
11+
(such as Save New Account, Update Product, Show Post) by manipulating the model
12+
and directing data to the view.
13+
14+
In Rails, the model is handled by what's called an object-relational mapping
15+
layer entitled Active Record. This layer allows you to present the data from
16+
database rows as objects and embellish these data objects with business logic
17+
methods. You can read more about Active Record in
18+
link:files/vendor/rails/activerecord/README.html.
19+
20+
The controller and view are handled by the Action Pack, which handles both
21+
layers by its two parts: Action View and Action Controller. These two layers
22+
are bundled in a single package due to their heavy interdependence. This is
23+
unlike the relationship between the Active Record and Action Pack that is much
24+
more separate. Each of these packages can be used independently outside of
25+
Rails. You can read more about Action Pack in
26+
link:files/vendor/rails/actionpack/README.html.
27+
28+
29+
== Getting Started
30+
31+
1. At the command prompt, create a new Rails application:
32+
<tt>rails new myapp</tt> (where <tt>myapp</tt> is the application name)
33+
34+
2. Change directory to <tt>myapp</tt> and start the web server:
35+
<tt>cd myapp; rails server</tt> (run with --help for options)
36+
37+
3. Go to http://localhost:3000/ and you'll see:
38+
"Welcome aboard: You're riding Ruby on Rails!"
39+
40+
4. Follow the guidelines to start developing your application. You can find
41+
the following resources handy:
42+
43+
* The Getting Started Guide: http://guides.rubyonrails.org/getting_started.html
44+
* Ruby on Rails Tutorial Book: http://www.railstutorial.org/
45+
46+
47+
== Debugging Rails
48+
49+
Sometimes your application goes wrong. Fortunately there are a lot of tools that
50+
will help you debug it and get it back on the rails.
51+
52+
First area to check is the application log files. Have "tail -f" commands
53+
running on the server.log and development.log. Rails will automatically display
54+
debugging and runtime information to these files. Debugging info will also be
55+
shown in the browser on requests from 127.0.0.1.
56+
57+
You can also log your own messages directly into the log file from your code
58+
using the Ruby logger class from inside your controllers. Example:
59+
60+
class WeblogController < ActionController::Base
61+
def destroy
62+
@weblog = Weblog.find(params[:id])
63+
@weblog.destroy
64+
logger.info("#{Time.now} Destroyed Weblog ID ##{@weblog.id}!")
65+
end
66+
end
67+
68+
The result will be a message in your log file along the lines of:
69+
70+
Mon Oct 08 14:22:29 +1000 2007 Destroyed Weblog ID #1!
71+
72+
More information on how to use the logger is at http://www.ruby-doc.org/core/
73+
74+
Also, Ruby documentation can be found at http://www.ruby-lang.org/. There are
75+
several books available online as well:
76+
77+
* Programming Ruby: http://www.ruby-doc.org/docs/ProgrammingRuby/ (Pickaxe)
78+
* Learn to Program: http://pine.fm/LearnToProgram/ (a beginners guide)
79+
80+
These two books will bring you up to speed on the Ruby language and also on
81+
programming in general.
82+
83+
84+
== Debugger
85+
86+
Debugger support is available through the debugger command when you start your
87+
Mongrel or WEBrick server with --debugger. This means that you can break out of
88+
execution at any point in the code, investigate and change the model, and then,
89+
resume execution! You need to install ruby-debug to run the server in debugging
90+
mode. With gems, use <tt>sudo gem install ruby-debug</tt>. Example:
91+
92+
class WeblogController < ActionController::Base
93+
def index
94+
@posts = Post.all
95+
debugger
96+
end
97+
end
98+
99+
So the controller will accept the action, run the first line, then present you
100+
with a IRB prompt in the server window. Here you can do things like:
101+
102+
>> @posts.inspect
103+
=> "[#<Post:0x14a6be8
104+
@attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>,
105+
#<Post:0x14a6620
106+
@attributes={"title"=>"Rails", "body"=>"Only ten..", "id"=>"2"}>]"
107+
>> @posts.first.title = "hello from a debugger"
108+
=> "hello from a debugger"
109+
110+
...and even better, you can examine how your runtime objects actually work:
111+
112+
>> f = @posts.first
113+
=> #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>
114+
>> f.
115+
Display all 152 possibilities? (y or n)
116+
117+
Finally, when you're ready to resume execution, you can enter "cont".
118+
119+
120+
== Console
121+
122+
The console is a Ruby shell, which allows you to interact with your
123+
application's domain model. Here you'll have all parts of the application
124+
configured, just like it is when the application is running. You can inspect
125+
domain models, change values, and save to the database. Starting the script
126+
without arguments will launch it in the development environment.
127+
128+
To start the console, run <tt>rails console</tt> from the application
129+
directory.
130+
131+
Options:
132+
133+
* Passing the <tt>-s, --sandbox</tt> argument will rollback any modifications
134+
made to the database.
135+
* Passing an environment name as an argument will load the corresponding
136+
environment. Example: <tt>rails console production</tt>.
137+
138+
To reload your controllers and models after launching the console run
139+
<tt>reload!</tt>
140+
141+
More information about irb can be found at:
142+
link:http://www.rubycentral.org/pickaxe/irb.html
143+
144+
145+
== dbconsole
146+
147+
You can go to the command line of your database directly through <tt>rails
148+
dbconsole</tt>. You would be connected to the database with the credentials
149+
defined in database.yml. Starting the script without arguments will connect you
150+
to the development database. Passing an argument will connect you to a different
151+
database, like <tt>rails dbconsole production</tt>. Currently works for MySQL,
152+
PostgreSQL and SQLite 3.

196+
app
197+
Holds all the code that's specific to this particular application.
198+
199+
app/assets
200+
Contains subdirectories for images, stylesheets, and JavaScript files.
201+
202+
app/controllers
203+
Holds controllers that should be named like weblogs_controller.rb for
204+
automated URL mapping. All controllers should descend from
205+
ApplicationController which itself descends from ActionController::Base.
206+
207+
app/models
208+
Holds models that should be named like post.rb. Models descend from
209+
ActiveRecord::Base by default.
210+
211+
app/views
212+
Holds the template files for the view that should be named like
213+
weblogs/index.html.erb for the WeblogsController#index action. All views use
214+
eRuby syntax by default.
215+
216+
app/views/layouts
217+
Holds the template files for layouts to be used with views. This models the
218+
common header/footer method of wrapping views. In your views, define a layout
219+
using the <tt>layout :default</tt> and create a file named default.html.erb.
220+
Inside default.html.erb, call <% yield %> to render the view using this
221+
layout.
222+
223+
app/helpers
224+
Holds view helpers that should be named like weblogs_helper.rb. These are
225+
generated for you automatically when using generators for controllers.
226+
Helpers can be used to wrap functionality for your views into methods.
227+
228+
config
229+
Configuration files for the Rails environment, the routing map, the database,
230+
and other dependencies.
231+
232+
db
233+
Contains the database schema in schema.rb. db/migrate contains all the
234+
sequence of Migrations for your schema.
235+
236+
doc
237+
This directory is where your application documentation will be stored when
238+
generated using <tt>rake doc:app</tt>
239+
240+
lib
241+
Application specific libraries. Basically, any kind of custom code that
242+
doesn't belong under controllers, models, or helpers. This directory is in
243+
the load path.
244+
245+
public
246+
The directory available for the web server. Also contains the dispatchers and the
247+
default HTML files. This should be set as the DOCUMENT_ROOT of your web
248+
server.
249+
250+
script
251+
Helper scripts for automation and generation.
252+
253+
test
254+
Unit and functional tests along with fixtures. When using the rails generate
255+
command, template test files will be generated for you and placed in this
256+
directory.
257+
258+
vendor
259+
External libraries that the application depends on. Also includes the plugins
260+
subdirectory. If the app has frozen rails, those gems also go here, under
261+
vendor/rails/. This directory is in the load path.
