-= Active Record -- Object-relation mapping put on rails
-
-Active Record connects business objects and database tables to create a persistable
-domain model where logic and data are presented in one wrapping. It's an implementation 
-of the object-relational mapping (ORM) pattern[http://www.martinfowler.com/eaaCatalog/activeRecord.html] 
-by the same name as described by Martin Fowler:
-
-  "An object that wraps a row in a database table or view, encapsulates 
-       the database access, and adds domain logic on that data."
-
-Active Record's main contribution to the pattern is to relieve the original of two stunting problems:
-lack of associations and inheritance. By adding a simple domain language-like set of macros to describe
-the former and integrating the Single Table Inheritance pattern for the latter, Active Record narrows the
-gap of functionality between the data mapper and active record approach.
-
-A short rundown of the major features:
-
-* Automated mapping between classes and tables, attributes and columns.
-
-   class Product < ActiveRecord::Base; end
-   
-   ...is automatically mapped to the table named "products", such as:
-   
-   CREATE TABLE products (
-     id int(11) NOT NULL auto_increment,
-     name varchar(255),
-     PRIMARY KEY  (id)
-   );
-
-   ...which again gives Product#name and Product#name=(new_name) 
-

-
-
-* Associations between objects controlled by simple meta-programming macros. 
-
-   class Firm < ActiveRecord::Base
-     has_many   :clients
-     has_one    :account
-     belongs_to :conglomorate
-   end
-
-  {Learn more}[link:classes/ActiveRecord/Associations/ClassMethods.html]
-
-
-* Aggregations of value objects controlled by simple meta-programming macros. 
-
-   class Account < ActiveRecord::Base
-     composed_of :balance, :class_name => "Money",
-                 :mapping => %w(balance amount)
-     composed_of :address, 
-                 :mapping => [%w(address_street street), %w(address_city city)]
-   end
-
-  {Learn more}[link:classes/ActiveRecord/Aggregations/ClassMethods.html]
-
-
-* Validation rules that can differ for new or existing objects.
-
-    class Account < ActiveRecord::Base
-      validates_presence_of     :subdomain, :name, :email_address, :password
-      validates_uniqueness_of   :subdomain
-      validates_acceptance_of   :terms_of_service, :on => :create
-      validates_confirmation_of :password, :email_address, :on => :create
-    end
-
-  {Learn more}[link:classes/ActiveRecord/Validations.html]
- 
-* Callbacks as methods or queues on the entire lifecycle (instantiation, saving, destroying, validating, etc).
-
-   class Person < ActiveRecord::Base
-     def before_destroy # is called just before Person#destroy
-       CreditCard.find(credit_card_id).destroy
-     end
-   end
-
-   class Account < ActiveRecord::Base
-     after_find :eager_load, 'self.class.announce(#{id})'
-   end
-
-  {Learn more}[link:classes/ActiveRecord/Callbacks.html]
-
-
-* Observers for the entire lifecycle
-
-   class CommentObserver < ActiveRecord::Observer
-     def after_create(comment) # is called just after Comment#save
-       Notifications.deliver_new_comment("david@loudthinking.com", comment)
-     end
-   end
-
-  {Learn more}[link:classes/ActiveRecord/Observer.html]
-
-
-* Inheritance hierarchies 
-
-   class Company < ActiveRecord::Base; end
-   class Firm < Company; end
-   class Client < Company; end
-   class PriorityClient < Client; end
-
-  {Learn more}[link:classes/ActiveRecord/Base.html]
-
-
-* Transactions
-
-    # Database transaction
-    Account.transaction do
-      david.withdrawal(100)
-      mary.deposit(100)
-    end
-
-  {Learn more}[link:classes/ActiveRecord/Transactions/ClassMethods.html]
-
-
-* Reflections on columns, associations, and aggregations
-
-    reflection = Firm.reflect_on_association(:clients)
-    reflection.klass # => Client (class)
-    Firm.columns # Returns an array of column descriptors for the firms table
-
-  {Learn more}[link:classes/ActiveRecord/Reflection/ClassMethods.html]
-
-
-* Direct manipulation (instead of service invocation)
-
-  So instead of (Hibernate[http://www.hibernate.org/] example):
-
-     long pkId = 1234;
-     DomesticCat pk = (DomesticCat) sess.load( Cat.class, new Long(pkId) );
-     // something interesting involving a cat...
-     sess.save(cat);
-     sess.flush(); // force the SQL INSERT
-
-  Active Record lets you:
-
-     pkId = 1234
-     cat = Cat.find(pkId)
-     # something even more interesting involving the same cat...
-     cat.save
-
-  {Learn more}[link:classes/ActiveRecord/Base.html]
-
-
-* Database abstraction through simple adapters (~100 lines) with a shared connector
-
-   ActiveRecord::Base.establish_connection(:adapter => "sqlite", :database => "dbfile")
-
-   ActiveRecord::Base.establish_connection(
-     :adapter  => "mysql", 
-     :host     => "localhost", 
-     :username => "me", 
-     :password => "secret", 
-     :database => "activerecord"
-   )
-
-  {Learn more}[link:classes/ActiveRecord/Base.html#M000081] and read about the built-in support for
-  MySQL[link:classes/ActiveRecord/ConnectionAdapters/MysqlAdapter.html], PostgreSQL[link:classes/ActiveRecord/ConnectionAdapters/PostgreSQLAdapter.html], SQLite[link:classes/ActiveRecord/ConnectionAdapters/SQLiteAdapter.html], Oracle[link:classes/ActiveRecord/ConnectionAdapters/OracleAdapter.html], SQLServer[link:classes/ActiveRecord/ConnectionAdapters/SQLServerAdapter.html], and DB2[link:classes/ActiveRecord/ConnectionAdapters/DB2Adapter.html].
-
-
-* Logging support for Log4r[http://log4r.sourceforge.net] and Logger[http://www.ruby-doc.org/stdlib/libdoc/logger/rdoc]
-
-    ActiveRecord::Base.logger = Logger.new(STDOUT)
-    ActiveRecord::Base.logger = Log4r::Logger.new("Application Log")
-
-
-* Database agnostic schema management with Migrations
-
-    class AddSystemSettings < ActiveRecord::Migration
-      def self.up
-        create_table :system_settings do |t|
-          t.string :name
-          t.string :label
-          t.text :value
-          t.string :type
-          t.integer  :position
-        end
-
-        SystemSetting.create :name => "notice", :label => "Use notice?", :value => 1
-      end
-
-      def self.down
-        drop_table :system_settings
-      end
-    end

-== Simple example (1/2): Defining tables and classes (using MySQL)
-
-Data definitions are specified only in the database. Active Record queries the database for 
-the column names (that then serves to determine which attributes are valid) on regular
-object instantiation through the new constructor and relies on the column names in the rows
-with the finders.
- 
-   # CREATE TABLE companies (
-   #   id int(11) unsigned NOT NULL auto_increment,
-   #   client_of int(11),
-   #   name varchar(255),
-   #   type varchar(100),
-   #   PRIMARY KEY  (id)
-   # )
-
-Active Record automatically links the "Company" object to the "companies" table
-
-   class Company < ActiveRecord::Base
-     has_many :people, :class_name => "Person"
-   end
-
-   class Firm < Company
-     has_many :clients
-  
-     def people_with_all_clients
-      clients.inject([]) { |people, client| people + client.people }
-     end
-   end
-
-The foreign_key is only necessary because we didn't use "firm_id" in the data definition
- 
-   class Client < Company
-     belongs_to :firm, :foreign_key => "client_of"
-   end
-
-   # CREATE TABLE people (
-   #   id int(11) unsigned NOT NULL auto_increment,
-   #   name text,
-   #   company_id text,
-   #   PRIMARY KEY  (id)
-   # )
-
-Active Record will also automatically link the "Person" object to the "people" table
-
-   class Person < ActiveRecord::Base
-     belongs_to :company
-   end
-
-== Simple example (2/2): Using the domain
-
-Picking a database connection for all the Active Records
-
-   ActiveRecord::Base.establish_connection(
-     :adapter  => "mysql", 
-     :host     => "localhost", 
-     :username => "me", 
-     :password => "secret", 
-     :database => "activerecord"
-   )
-
-Create some fixtures
-
-   firm = Firm.new("name" => "Next Angle")
-   # SQL: INSERT INTO companies (name, type) VALUES("Next Angle", "Firm")
-   firm.save
-
-   client = Client.new("name" => "37signals", "client_of" => firm.id)
-   # SQL: INSERT INTO companies (name, client_of, type) VALUES("37signals", 1, "Firm")
-   client.save
-
-Lots of different finders
-
-   # SQL: SELECT * FROM companies WHERE id = 1
-   next_angle = Company.find(1)
-
-   # SQL: SELECT * FROM companies WHERE id = 1 AND type = 'Firm'
-   next_angle = Firm.find(1)    
-
-   # SQL: SELECT * FROM companies WHERE id = 1 AND name = 'Next Angle'
-   next_angle = Company.find(:first, :conditions => "name = 'Next Angle'")
-
-   next_angle = Firm.find_by_sql("SELECT * FROM companies WHERE id = 1").first
-
-The supertype, Company, will return subtype instances
-
-   Firm === next_angle
-
-All the dynamic methods added by the has_many macro
-
-  next_angle.clients.empty?  # true
-  next_angle.clients.size    # total number of clients
-  all_clients = next_angle.clients
-
-Constrained finds makes access security easier when ID comes from a web-app
-
-   # SQL: SELECT * FROM companies WHERE client_of = 1 AND type = 'Client' AND id = 2
-   thirty_seven_signals = next_angle.clients.find(2)
-
-Bi-directional associations thanks to the "belongs_to" macro
-
-   thirty_seven_signals.firm.nil? # true
-
-
-== Philosophy 
-
-Active Record attempts to provide a coherent wrapper as a solution for the inconvenience that is 
-object-relational mapping. The prime directive for this mapping has been to minimize
-the amount of code needed to build a real-world domain model. This is made possible
-by relying on a number of conventions that make it easy for Active Record to infer
-complex relations and structures from a minimal amount of explicit direction.
-
-Convention over Configuration:
-* No XML-files!
-* Lots of reflection and run-time extension
-* Magic is not inherently a bad word 
-
-Admit the Database:
-* Lets you drop down to SQL for odd cases and performance
-* Doesn't attempt to duplicate or replace data definitions
-
