# == Single table inheritance
#
- # Active Record allows inheritance by storing the name of the class in a column that by
- # default is named "type" (can be changed by overwriting <tt>Base.inheritance_column</tt>).
- # This means that an inheritance looking like this:
- #
- # class Company < ActiveRecord::Base; end
- # class Firm < Company; end
- # class Client < Company; end
- # class PriorityClient < Client; end
- #
- # When you do <tt>Firm.create(name: "37signals")</tt>, this record will be saved in
- # the companies table with type = "Firm". You can then fetch this row again using
- # <tt>Company.where(name: '37signals').first</tt> and it will return a Firm object.
- #
- # If you don't have a type column defined in your table, single-table inheritance won't
- # be triggered. In that case, it'll work just like normal subclasses with no special magic
- # for differentiating between them or reloading the right type with find.
- #
- # Note, all the attributes for all the cases are kept in the same table. Read more:
