Module: Tenacity::OrmExt::DataMapper

Defined in:
lib/tenacity/orm_ext/datamapper.rb

Overview

Tenacity relationships on DataMapper objects require that certain columns exist on the associated table. Take the following class for example:

class Car
  include DataMapper::Resource
  include Tenacity

  property :id, Serial
  property :driver_id, String

  t_has_many    :wheels
  t_has_one     :dashboard
  t_belongs_to  :driver
end

t_belongs_to

The t_belongs_to association requires that a property exist in the table to hold the id of the assoicated object.

t_has_one

The t_has_one association requires no special column in the table, since the associated object holds the foreign key.

t_has_many

The t_has_many association requires nothing special, as the associates are looked up using the associate class.
