module Tenacity::OrmExt::DataMapper
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.
