+= 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) 
+   
+  {Learn more}[link:classes/ActiveRecord/Base.html]
+
+
+* 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]
+
+
+* Transaction support on both a database and object level. The latter is implemented 
+  by using Transaction::Simple[http://railsmanual.com/module/Transaction::Simple]
+
+    # Just database transaction
+    Account.transaction do
+      david.withdrawal(100)
+      mary.deposit(100)
+    end
+
+    # Database and object transaction
+    Account.transaction(david, mary) 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")
+
+
+== 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
+
+
+== Examples
+
+Active Record ships with a couple of examples that should give you a good feel for
+operating usage. Be sure to edit the <tt>examples/shared_setup.rb</tt> file for your
+own database before running the examples. Possibly also the table definition SQL in 
+the examples themselves.
+
+It's also highly recommended to have a look at the unit tests. Read more in link:files/RUNNING_UNIT_TESTS.html
+
+
+== 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
+
+
+== Download
+
+The latest version of Active Record can be found at

+
+Documentation can be found at 
+
+* http://ar.rubyonrails.com
+
+
+== Installation
+
+The prefered method of installing Active Record is through its GEM file. You'll need to have
+RubyGems[http://rubygems.rubyforge.org/wiki/wiki.pl] installed for that, though. If you have,
+then use:
+
+  % [sudo] gem install activerecord-1.10.0.gem
+
+You can also install Active Record the old-fashion way with the following command:
+
+  % [sudo] ruby install.rb
+
+from its distribution directory.
+
+
+== License
+
+Active Record is released under the MIT license.
+
+
+== Support
+
+The Active Record homepage is http://www.rubyonrails.com. You can find the Active Record
+RubyForge page at http://rubyforge.org/projects/activerecord. And as Jim from Rake says:
+
+   Feel free to submit commits or feature requests.  If you send a patch,
+   remember to update the corresponding unit tests.  If fact, I prefer
+   new feature to be submitted in the form of new unit tests.
+
+For other information, feel free to ask on the ruby-talk mailing list
+(which is mirrored to comp.lang.ruby) or contact mailto:david@loudthinking.com.

+== Creating the test database
+
+The default names for the test databases are "activerecord_unittest" and 
+"activerecord_unittest2". If you want to use another database name then be sure 
+to update the connection adapter setups you want to test with in 
+test/connections/<your database>/connection.rb. 
+When you have the database online, you can import the fixture tables with 
+the test/fixtures/db_definitions/*.sql files.
+
+Make sure that you create database objects with the same user that you specified in 
+connection.rb otherwise (on Postgres, at least) tests for default values will fail.
+
+== Running with Rake
+
+The easiest way to run the unit tests is through Rake. The default task runs
+the entire test suite for all the adapters. You can also run the suite on just
+one adapter by using the tasks test_mysql, test_sqlite, test_postgresql or any
+of the other test_ tasks. For more information, checkout the full array of rake
+tasks with "rake -T"
+
+Rake can be found at http://rake.rubyforge.org
+
+== Running by hand
+
+Unit tests are located in test directory. If you only want to run a single test suite, 
+you can do so with:
+
+   rake test_mysql TEST=base_test.rb
+   
+That'll run the base suite using the MySQL-Ruby adapter.

+    # Active Record implements aggregation through a macro-like class method called +composed_of+ for representing attributes 
+    # as value objects. It expresses relationships like "Account [is] composed of Money [among other things]" or "Person [is]
+    # composed of [an] address". Each call to the macro adds a description of how the value objects are created from the 
+    # attributes of the entity object (when the entity is initialized either as a new object or from finding an existing object) 
+    # and how it can be turned back into attributes (when the entity is saved to the database). Example:
+    #
+    #   class Customer < 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
+    #
+    # The customer class now has the following methods to manipulate the value objects:
+    # * <tt>Customer#balance, Customer#balance=(money)</tt>
+    # * <tt>Customer#address, Customer#address=(address)</tt>
+    #
+    # These methods will operate with value objects like the ones described below:
+    #
+    #  class Money
+    #    include Comparable
+    #    attr_reader :amount, :currency
+    #    EXCHANGE_RATES = { "USD_TO_DKK" => 6 }  
+    # 
+    #    def initialize(amount, currency = "USD") 
+    #      @amount, @currency = amount, currency 
+    #    end
+    #
+    #    def exchange_to(other_currency)
+    #      exchanged_amount = (amount * EXCHANGE_RATES["#{currency}_TO_#{other_currency}"]).floor
+    #      Money.new(exchanged_amount, other_currency)
+    #    end
+    #
+    #    def ==(other_money)
+    #      amount == other_money.amount && currency == other_money.currency
+    #    end
+    #
+    #    def <=>(other_money)
+    #      if currency == other_money.currency
+    #        amount <=> amount
+    #      else
+    #        amount <=> other_money.exchange_to(currency).amount
+    #      end
+    #    end
+    #  end
+    #
+    #  class Address
+    #    attr_reader :street, :city
+    #    def initialize(street, city) 
+    #      @street, @city = street, city 
+    #    end
+    #
+    #    def close_to?(other_address) 
+    #      city == other_address.city 
+    #    end
+    #
+    #    def ==(other_address)
+    #      city == other_address.city && street == other_address.street
+    #    end
+    #  end
+    #  
+    # Now it's possible to access attributes from the database through the value objects instead. If you choose to name the
+    # composition the same as the attribute's name, it will be the only way to access that attribute. That's the case with our
+    # +balance+ attribute. You interact with the value objects just like you would any other attribute, though:
+    #
+    #   customer.balance = Money.new(20)     # sets the Money value object and the attribute
+    #   customer.balance                     # => Money value object
+    #   customer.balance.exchanged_to("DKK") # => Money.new(120, "DKK")
+    #   customer.balance > Money.new(10)     # => true
+    #   customer.balance == Money.new(20)    # => true
+    #   customer.balance < Money.new(5)      # => false
+    #
+    # Value objects can also be composed of multiple attributes, such as the case of Address. The order of the mappings will
+    # determine the order of the parameters. Example:
+    #
+    #   customer.address_street = "Hyancintvej"
+    #   customer.address_city   = "Copenhagen"
+    #   customer.address        # => Address.new("Hyancintvej", "Copenhagen")
+    #   customer.address = Address.new("May Street", "Chicago")
+    #   customer.address_street # => "May Street" 
+    #   customer.address_city   # => "Chicago" 
+    #
+    # == Writing value objects
+    #
+    # Value objects are immutable and interchangeable objects that represent a given value, such as a +Money+ object representing
+    # $5. Two +Money+ objects both representing $5 should be equal (through methods such as == and <=> from +Comparable+ if ranking
+    # makes sense). This is unlike entity objects where equality is determined by identity. An entity class such as +Customer+ can
+    # easily have two different objects that both have an address on Hyancintvej. Entity identity is determined by object or
+    # relational unique identifiers (such as primary keys). Normal <tt>ActiveRecord::Base</tt> classes are entity objects.
+    #
+    # It's also important to treat the value objects as immutable. Don't allow the +Money+ object to have its amount changed after
+    # creation. Create a new +Money+ object with the new value instead. This is exemplified by the <tt>Money#exchanged_to</tt> method that
+    # returns a new value object instead of changing its own values. Active Record won't persist value objects that have been
+    # changed through means other than the writer method.
+    #
+    # The immutable requirement is enforced by Active Record by freezing any object assigned as a value object. Attempting to 
+    # change it afterwards will result in a <tt>TypeError</tt>.
+    # 
+    # Read more about value objects on http://c2.com/cgi/wiki?ValueObject and on the dangers of not keeping value objects
+    # immutable on http://c2.com/cgi/wiki?ValueObjectsShouldBeImmutable
+    module ClassMethods
+      # Adds reader and writer methods for manipulating a value object:
+      # <tt>composed_of :address</tt> adds <tt>address</tt> and <tt>address=(new_address)</tt> methods.
+      #
+      # Options are:
+      # * <tt>:class_name</tt>  - specify the class name of the association. Use it only if that name can't be inferred
+      #   from the part id. So <tt>composed_of :address</tt> will by default be linked to the +Address+ class, but
+      #   if the real class name is +CompanyAddress+, you'll have to specify it with this option.
+      # * <tt>:mapping</tt> - specifies a number of mapping arrays (attribute, parameter) that bind an attribute name
+      #   to a constructor parameter on the value class.
+      # * <tt>:allow_nil</tt> - specifies that the aggregate object will not be instantiated when all mapped
+      #   attributes are +nil+.  Setting the aggregate class to +nil+ has the effect of writing +nil+ to all mapped attributes.
+      #   This defaults to +false+.
+      #
+      # An optional block can be passed to convert the argument that is passed to the writer method into an instance of
+      # <tt>:class_name</tt>. The block will only be called if the argument is not already an instance of <tt>:class_name</tt>.
+      #
+      # Option examples:
+      #   composed_of :temperature, :mapping => %w(reading celsius)
+      #   composed_of(:balance, :class_name => "Money", :mapping => %w(balance amount)) {|balance| balance.to_money }

+      #   to already defined associations. When using named associations, count returns the number of DISTINCT items for the model you're counting.
+      #   See eager loading under Associations.
+      # * <tt>:order</tt>: An SQL fragment like "created_at DESC, name" (really only used with GROUP BY calculations).
+      # * <tt>:group</tt>: An attribute name by which the result should be grouped. Uses the GROUP BY SQL-clause.

+      # * <tt>:joins</tt> - An SQL fragment for additional joins like "LEFT JOIN comments ON comments.post_id = id". (Rarely needed).
+      #   The records will be returned read-only since they will have attributes that do not correspond to the table's columns.
+      # * <tt>:order</tt> - An SQL fragment like "created_at DESC, name" (really only used with GROUP BY calculations).
+      # * <tt>:group</tt> - An attribute name by which the result should be grouped. Uses the GROUP BY SQL-clause.

+module ActiveRecord
+  # Callbacks are hooks into the lifecycle of an Active Record object that allow you to trigger logic
+  # before or after an alteration of the object state. This can be used to make sure that associated and
+  # dependent objects are deleted when destroy is called (by overwriting +before_destroy+) or to massage attributes
+  # before they're validated (by overwriting +before_validation+). As an example of the callbacks initiated, consider
+  # the <tt>Base#save</tt> call:
+  #
+  # * (-) <tt>save</tt>
+  # * (-) <tt>valid</tt>
+  # * (1) <tt>before_validation</tt>
+  # * (2) <tt>before_validation_on_create</tt>
+  # * (-) <tt>validate</tt>
+  # * (-) <tt>validate_on_create</tt>
+  # * (3) <tt>after_validation</tt>
+  # * (4) <tt>after_validation_on_create</tt>
+  # * (5) <tt>before_save</tt>
+  # * (6) <tt>before_create</tt>
+  # * (-) <tt>create</tt>
+  # * (7) <tt>after_create</tt>
+  # * (8) <tt>after_save</tt>
+  #
+  # That's a total of eight callbacks, which gives you immense power to react and prepare for each state in the
+  # Active Record lifecycle.
+  #
+  # Examples:
+  #   class CreditCard < ActiveRecord::Base
+  #     # Strip everything but digits, so the user can specify "555 234 34" or
+  #     # "5552-3434" or both will mean "55523434"
+  #     def before_validation_on_create
+  #       self.number = number.gsub(/[^0-9]/, "") if attribute_present?("number")
+  #     end
+  #   end
+  #
+  #   class Subscription < ActiveRecord::Base
+  #     before_create :record_signup
+  #
+  #     private
+  #       def record_signup
+  #         self.signed_up_on = Date.today
+  #       end
+  #   end
+  #
+  #   class Firm < ActiveRecord::Base
+  #     # Destroys the associated clients and people when the firm is destroyed
+  #     before_destroy { |record| Person.destroy_all "firm_id = #{record.id}"   }
+  #     before_destroy { |record| Client.destroy_all "client_of = #{record.id}" }
+  #   end
+  #
+  # == Inheritable callback queues
+  #
+  # Besides the overwriteable callback methods, it's also possible to register callbacks through the use of the callback macros.
+  # Their main advantage is that the macros add behavior into a callback queue that is kept intact down through an inheritance
+  # hierarchy. Example:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     before_destroy :destroy_author
+  #   end
+  #
+  #   class Reply < Topic
+  #     before_destroy :destroy_readers
+  #   end
+  #
+  # Now, when <tt>Topic#destroy</tt> is run only +destroy_author+ is called. When <tt>Reply#destroy</tt> is run, both +destroy_author+ and
+  # +destroy_readers+ are called. Contrast this to the situation where we've implemented the save behavior through overwriteable
+  # methods:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     def before_destroy() destroy_author end
+  #   end
+  #
+  #   class Reply < Topic
+  #     def before_destroy() destroy_readers end
+  #   end
+  #
+  # In that case, <tt>Reply#destroy</tt> would only run +destroy_readers+ and _not_ +destroy_author+. So, use the callback macros when
+  # you want to ensure that a certain callback is called for the entire hierarchy, and use the regular overwriteable methods
+  # when you want to leave it up to each descendent to decide whether they want to call +super+ and trigger the inherited callbacks.
+  #
+  # *IMPORTANT:* In order for inheritance to work for the callback queues, you must specify the callbacks before specifying the
+  # associations. Otherwise, you might trigger the loading of a child before the parent has registered the callbacks and they won't
+  # be inherited.
+  #
+  # == Types of callbacks
+  #
+  # There are four types of callbacks accepted by the callback macros: Method references (symbol), callback objects,
+  # inline methods (using a proc), and inline eval methods (using a string). Method references and callback objects are the
+  # recommended approaches, inline methods using a proc are sometimes appropriate (such as for creating mix-ins), and inline
+  # eval methods are deprecated.
+  #
+  # The method reference callbacks work by specifying a protected or private method available in the object, like this:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     before_destroy :delete_parents
+  #
+  #     private
+  #       def delete_parents
+  #         self.class.delete_all "parent_id = #{id}"
+  #       end
+  #   end
+  #
+  # The callback objects have methods named after the callback called with the record as the only parameter, such as:
+  #
+  #   class BankAccount < ActiveRecord::Base
+  #     before_save      EncryptionWrapper.new("credit_card_number")
+  #     after_save       EncryptionWrapper.new("credit_card_number")
+  #     after_initialize EncryptionWrapper.new("credit_card_number")
+  #   end
+  #
+  #   class EncryptionWrapper
+  #     def initialize(attribute)
+  #       @attribute = attribute
+  #     end
+  #
+  #     def before_save(record)
+  #       record.credit_card_number = encrypt(record.credit_card_number)
+  #     end
+  #
+  #     def after_save(record)
+  #       record.credit_card_number = decrypt(record.credit_card_number)
+  #     end
+  #
+  #     alias_method :after_find, :after_save
+  #
+  #     private
+  #       def encrypt(value)
+  #         # Secrecy is committed
+  #       end
+  #
+  #       def decrypt(value)
+  #         # Secrecy is unveiled
+  #       end
+  #   end
+  #
+  # So you specify the object you want messaged on a given callback. When that callback is triggered, the object has
+  # a method by the name of the callback messaged.
+  #
+  # The callback macros usually accept a symbol for the method they're supposed to run, but you can also pass a "method string",
+  # which will then be evaluated within the binding of the callback. Example:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     before_destroy 'self.class.delete_all "parent_id = #{id}"'
+  #   end
+  #
+  # Notice that single quotes (') are used so the <tt>#{id}</tt> part isn't evaluated until the callback is triggered. Also note that these
+  # inline callbacks can be stacked just like the regular ones:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     before_destroy 'self.class.delete_all "parent_id = #{id}"',
+  #                    'puts "Evaluated after parents are destroyed"'
+  #   end
+  #
+  # == The +after_find+ and +after_initialize+ exceptions
+  #
+  # Because +after_find+ and +after_initialize+ are called for each object found and instantiated by a finder, such as <tt>Base.find(:all)</tt>, we've had
+  # to implement a simple performance constraint (50% more speed on a simple test case). Unlike all the other callbacks, +after_find+ and
+  # +after_initialize+ will only be run if an explicit implementation is defined (<tt>def after_find</tt>). In that case, all of the
+  # callback types will be called.
+  #
+  # == <tt>before_validation*</tt> returning statements
+  #
+  # If the returning value of a +before_validation+ callback can be evaluated to +false+, the process will be aborted and <tt>Base#save</tt> will return +false+.
+  # If <tt>Base#save!</tt> is called it will raise a +RecordNotSaved+ exception.
+  # Nothing will be appended to the errors object.
+  #
+  # == Canceling callbacks
+  #
+  # If a <tt>before_*</tt> callback returns +false+, all the later callbacks and the associated action are cancelled. If an <tt>after_*</tt> callback returns
+  # +false+, all the later callbacks are cancelled. Callbacks are generally run in the order they are defined, with the exception of callbacks
+  # defined as methods on the model, which are called last.

+      # * <tt>:scale</tt> -
+      #   Specifies the scale for a <tt>:decimal</tt> column. 
+      #
+      # Please be aware of different RDBMS implementations behavior with

+      # * MySQL: <tt>:precision</tt> [1..63], <tt>:scale</tt> [0..30].

+      #
+      #  td.column(:sales_stage, :string, :limit => 20, :default => 'new', :null => false)
+      #    #=> sales_stage VARCHAR(20) DEFAULT 'new' NOT NULL
+      #
+      #  def.column(:bill_gates_money, :decimal, :precision => 15, :scale => 2)
+      #    #=> bill_gates_money DECIMAL(15,2)
+      #
+      #  def.column(:sensor_reading, :decimal, :precision => 30, :scale => 20)
+      #    #=> sensor_reading DECIMAL(30,20)
+      #
+      #  # While <tt>:scale</tt> defaults to zero on most databases, it
+      #  # probably wouldn't hurt to include it.
+      #  def.column(:huge_integer, :decimal, :precision => 30)
+      #    #=> huge_integer DECIMAL(30)
+      #
+      # == Short-hand examples
+      #
+      # Instead of calling column directly, you can also work with the short-hand definitions for the default types.
+      # They use the type as the method name instead of as a parameter and allow for multiple columns to be defined
+      # in a single statement.
+      #
+      # What can be written like this with the regular calls to column:
+      #
+      #   create_table "products", :force => true do |t|
+      #     t.column "shop_id",    :integer
+      #     t.column "creator_id", :integer
+      #     t.column "name",       :string,   :default => "Untitled"
+      #     t.column "value",      :string,   :default => "Untitled"
+      #     t.column "created_at", :datetime
+      #     t.column "updated_at", :datetime
+      #   end
+      #
+      # Can also be written as follows using the short-hand:
+      #
+      #   create_table :products do |t|
+      #     t.integer :shop_id, :creator_id
+      #     t.string  :name, :value, :default => "Untitled"
+      #     t.timestamps
+      #   end
+      #
+      # There's a short-hand method for each of the type values declared at the top. And then there's 
+      # TableDefinition#timestamps that'll add created_at and updated_at as datetimes.
+      #
+      # TableDefinition#references will add an appropriately-named _id column, plus a corresponding _type
+      # column if the :polymorphic option is supplied. If :polymorphic is a hash of options, these will be
+      # used when creating the _type column. So what can be written like this:
+      #
+      #   create_table :taggings do |t|
+      #     t.integer :tag_id, :tagger_id, :taggable_id
+      #     t.string  :tagger_type
+      #     t.string  :taggable_type, :default => 'Photo'
+      #   end
+      #
+      # Can also be written as follows using references:
+      #
+      #   create_table :taggings do |t|
+      #     t.references :tag
+      #     t.references :tagger, :polymorphic => true

+      # [+:first+, +:last+], the DBMS creates an index for both columns as well as an
+      # index for the first column +:first+. Using just the first name for this index
+      # makes sense, because you will never have to create a singular index with this
+      # name.

+    # == What is Optimistic Locking
+    #
+    # Optimistic locking allows multiple users to access the same record for edits, and assumes a minimum of
+    # conflicts with the data.  It does this by checking whether another process has made changes to a record since
+    # it was opened, an ActiveRecord::StaleObjectError is thrown if that has occurred and the update is ignored.
+    #
+    # Check out ActiveRecord::Locking::Pessimistic for an alternative.
+    #
+    # == Usage
+    #
+    # Active Records support optimistic locking if the field <tt>lock_version</tt> is present.  Each update to the
+    # record increments the lock_version column and the locking facilities ensure that records instantiated twice
+    # will let the last one saved raise a StaleObjectError if the first was also updated. Example:
+    #
+    #   p1 = Person.find(1)
+    #   p2 = Person.find(1)
+    #
+    #   p1.first_name = "Michael"
+    #   p1.save
+    #
+    #   p2.first_name = "should fail"
+    #   p2.save # Raises a ActiveRecord::StaleObjectError
+    #
+    # You're then responsible for dealing with the conflict by rescuing the exception and either rolling back, merging,
+    # or otherwise apply the business logic needed to resolve the conflict.
+    #
+    # You must ensure that your database schema defaults the lock_version column to 0.
+    #
+    # This behavior can be turned off by setting <tt>ActiveRecord::Base.lock_optimistically = false</tt>.
+    # To override the name of the lock_version column, invoke the <tt>set_locking_column</tt> method.
+    # This method uses the same syntax as <tt>set_table_name</tt>

+  # Example of a more complex migration that also needs to initialize data:
+  #
+  #   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
+  #
+  # This migration first adds the system_settings table, then creates the very first row in it using the Active Record model
+  # that relies on the table. It also uses the more advanced create_table syntax where you can specify a complete table schema
+  # in one block call.
+  #
+  # == Available transformations
+  #
+  # * <tt>create_table(name, options)</tt> Creates a table called +name+ and makes the table object available to a block
+  #   that can then add columns to it, following the same format as add_column. See example above. The options hash is for
+  #   fragments like "DEFAULT CHARSET=UTF-8" that are appended to the create table definition.
+  # * <tt>drop_table(name)</tt>: Drops the table called +name+.
+  # * <tt>rename_table(old_name, new_name)</tt>: Renames the table called +old_name+ to +new_name+.
+  # * <tt>add_column(table_name, column_name, type, options)</tt>: Adds a new column to the table called +table_name+
+  #   named +column_name+ specified to be one of the following types:
+  #   :string, :text, :integer, :float, :decimal, :datetime, :timestamp, :time,
+  #   :date, :binary, :boolean. A default value can be specified by passing an
+  #   +options+ hash like { :default => 11 }. Other options include :limit and :null (e.g. { :limit => 50, :null => false })
+  #   -- see ActiveRecord::ConnectionAdapters::TableDefinition#column for details.
+  # * <tt>rename_column(table_name, column_name, new_column_name)</tt>: Renames a column but keeps the type and content.
+  # * <tt>change_column(table_name, column_name, type, options)</tt>:  Changes the column to a different type using the same
+  #   parameters as add_column.
+  # * <tt>remove_column(table_name, column_name)</tt>: Removes the column named +column_name+ from the table called +table_name+.
+  # * <tt>add_index(table_name, column_names, options)</tt>: Adds a new index with the name of the column. Other options include
+  #   :name and :unique (e.g. { :name => "users_name_index", :unique => true }).
+  # * <tt>remove_index(table_name, index_name)</tt>: Removes the index specified by +index_name+.
+  #
+  # == Irreversible transformations
+  #
+  # Some transformations are destructive in a manner that cannot be reversed. Migrations of that kind should raise
+  # an <tt>ActiveRecord::IrreversibleMigration</tt> exception in their +down+ method.
+  #
+  # == Running migrations from within Rails
+  #
+  # The Rails package has several tools to help create and apply migrations.
+  #
+  # To generate a new migration, use <tt>script/generate migration MyNewMigration</tt>
+  # where MyNewMigration is the name of your migration. The generator will
+  # create a file <tt>nnn_my_new_migration.rb</tt> in the <tt>db/migrate/</tt>
+  # directory where <tt>nnn</tt> is the next largest migration number.
+  # You may then edit the <tt>self.up</tt> and <tt>self.down</tt> methods of
+  # MyNewMigration.
+  #
+  # To run migrations against the currently configured database, use
+  # <tt>rake db:migrate</tt>. This will update the database by running all of the
+  # pending migrations, creating the <tt>schema_info</tt> table if missing.
+  #
+  # To roll the database back to a previous migration version, use
+  # <tt>rake db:migrate VERSION=X</tt> where <tt>X</tt> is the version to which
+  # you wish to downgrade. If any of the migrations throw an
+  # <tt>ActiveRecord::IrreversibleMigration</tt> exception, that step will fail and you'll
+  # have some manual work to do.
+  #
+  # == Database support
+  #
+  # Migrations are currently supported in MySQL, PostgreSQL, SQLite,
+  # SQL Server, Sybase, and Oracle (all supported databases except DB2).
+  #
+  # == More examples
+  #
+  # Not all migrations change the schema. Some just fix the data:
+  #
+  #   class RemoveEmptyTags < ActiveRecord::Migration
+  #     def self.up
+  #       Tag.find(:all).each { |tag| tag.destroy if tag.pages.empty? }
+  #     end
+  #
+  #     def self.down
+  #       # not much we can do to restore deleted data
+  #       raise ActiveRecord::IrreversibleMigration, "Can't recover the deleted tags"
+  #     end
+  #   end
+  #
+  # Others remove columns when they migrate up instead of down:
+  #
+  #   class RemoveUnnecessaryItemAttributes < ActiveRecord::Migration
+  #     def self.up
+  #       remove_column :items, :incomplete_items_count
+  #       remove_column :items, :completed_items_count
+  #     end
+  #
+  #     def self.down
+  #       add_column :items, :incomplete_items_count
+  #       add_column :items, :completed_items_count
+  #     end
+  #   end
+  #
+  # And sometimes you need to do something in SQL not abstracted directly by migrations:
+  #
+  #   class MakeJoinUnique < ActiveRecord::Migration
+  #     def self.up
+  #       execute "ALTER TABLE `pages_linked_pages` ADD UNIQUE `page_id_linked_page_id` (`page_id`,`linked_page_id`)"
+  #     end
+  #
+  #     def self.down
+  #       execute "ALTER TABLE `pages_linked_pages` DROP INDEX `page_id_linked_page_id`"
+  #     end
+  #   end
+  #
+  # == Using a model after changing its table
+  #
+  # Sometimes you'll want to add a column in a migration and populate it immediately after. In that case, you'll need
+  # to make a call to Base#reset_column_information in order to ensure that the model has the latest column data from
+  # after the new column was added. Example:
+  #
+  #   class AddPeopleSalary < ActiveRecord::Migration
+  #     def self.up
+  #       add_column :people, :salary, :integer
+  #       Person.reset_column_information
+  #       Person.find(:all).each do |p|
+  #         p.update_attribute :salary, SalaryCalculator.compute(p)
+  #       end
+  #     end
+  #   end
+  #
+  # == Controlling verbosity
+  #
+  # By default, migrations will describe the actions they are taking, writing
+  # them to the console as they happen, along with benchmarks describing how
+  # long each step took.
+  #
+  # You can quiet them down by setting ActiveRecord::Migration.verbose = false.
+  #
+  # You can also insert your own messages and benchmarks by using the #say_with_time
+  # method:
+  #
+  #   def self.up
+  #     ...
+  #     say_with_time "Updating salaries..." do
+  #       Person.find(:all).each do |p|
+  #         p.update_attribute :salary, SalaryCalculator.compute(p)
+  #       end
+  #     end
+  #     ...
+  #   end
+  #
+  # The phrase "Updating salaries..." would then be printed, along with the
+  # benchmark for the block when the block completes.

+  # class. Example:
+  #
+  #   class CommentObserver < ActiveRecord::Observer
+  #     def after_save(comment)
+  #       Notifications.deliver_comment("admin@do.com", "New comment was posted", comment)

+  #     end
+  #   end
+  #
+  # This Observer uses logger to log when specific callbacks are triggered.
+  #
+  # == Observing a class that can't be inferred
+  #
+  # Observers will by default be mapped to the class with which they share a name. So CommentObserver will
+  # be tied to observing Comment, ProductManagerObserver to ProductManager, and so on. If you want to name your observer
+  # differently than the class you're interested in observing, you can use the Observer.observe class method which takes
+  # either the concrete class (Product) or a symbol for that class (:product):
+  #
+  #   class AuditObserver < ActiveRecord::Observer
+  #     observe :account
+  #
+  #     def after_update(account)
+  #       AuditTrail.new(account, "UPDATED")
+  #     end
+  #   end
+  #
+  # If the audit observer needs to watch more than one kind of object, this can be specified with multiple arguments:
+  #
+  #   class AuditObserver < ActiveRecord::Observer
+  #     observe :account, :balance
+  #
+  #     def after_update(record)
+  #       AuditTrail.new(record, "UPDATED")
+  #     end
+  #   end
+  #
+  # The AuditObserver will now act on both updates to Account and Balance by treating them both as records.
+  #
+  # == Available callback methods
+  #
+  # The observer can implement callback methods for each of the methods described in the Callbacks module.
+  #
+  # == Storing Observers in Rails
+  #
+  # If you're using Active Record within Rails, observer classes are usually stored in app/models with the
+  # naming convention of app/models/audit_observer.rb.
+  #
+  # == Configuration
+  #
+  # In order to activate an observer, list it in the <tt>config.active_record.observers</tt> configuration setting in your

+    # Transactions are protective blocks where SQL statements are only permanent if they can all succeed as one atomic action. 
+    # The classic example is a transfer between two accounts where you can only have a deposit if the withdrawal succeeded and
+    # vice versa. Transactions enforce the integrity of the database and guard the data against program errors or database break-downs.
+    # So basically you should use transaction blocks whenever you have a number of statements that must be executed together or
+    # not at all. Example:
+    #
+    #   transaction do
+    #     david.withdrawal(100)
+    #     mary.deposit(100)
+    #   end
+    #
+    # This example will only take money from David and give to Mary if neither +withdrawal+ nor +deposit+ raises an exception.
+    # Exceptions will force a ROLLBACK that returns the database to the state before the transaction was begun. Be aware, though,
+    # that the objects by default will _not_ have their instance data returned to their pre-transactional state.
+    #
+    # == Different ActiveRecord classes in a single transaction
+    #
+    # Though the transaction class method is called on some ActiveRecord class,
+    # the objects within the transaction block need not all be instances of
+    # that class.
+    # In this example a <tt>Balance</tt> record is transactionally saved even
+    # though <tt>transaction</tt> is called on the <tt>Account</tt> class:
+    #
+    #   Account.transaction do
+    #     balance.save!
+    #     account.save!
+    #   end
+    #
+    # == Transactions are not distributed across database connections
+    #
+    # A transaction acts on a single database connection.  If you have
+    # multiple class-specific databases, the transaction will not protect
+    # interaction among them.  One workaround is to begin a transaction
+    # on each class whose models you alter:
+    #
+    #   Student.transaction do
+    #     Course.transaction do
+    #       course.enroll(student)
+    #       student.units += course.units
+    #     end
+    #   end
+    #
+    # This is a poor solution, but full distributed transactions are beyond
+    # the scope of Active Record.
+    #
+    # == Save and destroy are automatically wrapped in a transaction
+    #
+    # Both Base#save and Base#destroy come wrapped in a transaction that ensures that whatever you do in validations or callbacks
+    # will happen under the protected cover of a transaction. So you can use validations to check for values that the transaction
+    # depends on or you can raise exceptions in the callbacks to rollback.
+    #
+    # == Exception handling
+    #
+    # Also have in mind that exceptions thrown within a transaction block will be propagated (after triggering the ROLLBACK), so you
+    # should be ready to catch those in your application code. One exception is the ActiveRecord::Rollback exception, which will
+    # trigger a ROLLBACK when raised, but not be re-raised by the transaction block.
