Public Class methods

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.
