== Description
A database client independent way of managing relationships between models backed by different databases.
It is sometimes necessary, or advantageous, to use more than one database in a given application (polyglot persistence). However, most database clients do not support inter-database relationships. So, writing code that manages relationships between objects backed by different databases hasn’t been nearly as easy as writing code to manage relationships between objects in the same database.
Tenacity aims to address this by providing a database client independent way of managing relationships between models backed by different databases.
Tenacity is heavily based on ActiveRecord's associations, and aims to behave in much the same way, supporting many of the same options.
== Example
class Car include MongoMapper::Document include Tenacity
t_has_many :wheels
t_has_one :dashboard
end
class Wheel < ActiveRecord::Base include Tenacity
t_belongs_to :car
end
class Dashboard < CouchRest::Model::Base include Tenacity use_database MY_COUCHDB_DATABASE
t_belongs_to :car
end
car = Car.create
dashboard = Dashboard.create({}) car.dashboard = dashboard car.save
car.dashboard
car.dashboard.car_id
wheel_1 = Wheel.create wheel_2 = Wheel.create wheel_3 = Wheel.create wheels = [wheel_1, wheel_2, wheel_3] car.wheels = wheels car.save
wheel_1.car_id # car.id
car.wheels # [wheel_1, wheel_2, wheel_3]
car.wheel_ids # [wheel_1.id, wheel_2.id, wheel_3.id]
new_wheel = Wheel.create car.wheels << new_wheel car.save car.wheels # [wheel_1, wheel_2, wheel_3, new_wheel]
