included(base)

All subclasses of ActiveRecord::Base have one named scope:

  • scoped- which allows for the creation of anonymous scopes, on the fly: Shirt.scoped(:conditions => {:color => 'red'}).scoped(:include => :washing_instructions)

These anonymous scopes tend to be useful when procedurally generating complex queries, where passing intermediate values (scopes) around as first-class objects is convenient.

You can define a scope that applies to all finders using ActiveRecord::Base.default_scope.

def self.included(base)
  base.extend ClassMethods
