gem 'unidom-standard'

Run the Database Migration

rake db:migrate

The migration versions start with 200006.

Call the Model

gbk = Unidom::Standard::Standard.number_is('GBK').first
gbk.source_standards.merge(Unidom::Standard::StandardAssociating.association_coded_as('REVS').valid_at.alive).valid_at.alive
# The standards revises GBK.
gbk.target_standards.merge(Unidom::Standard::StandardAssociating.association_coded_as('REVS').valid_at.alive).valid_at.alive
# The standards revised by GBK, such as GB2312.

# GBK revise GB2312
Unidom::Standard::StandardAssociating.associate! gbk, with: gb2312, due_to: 'REVS'

Inlcude the Concerns

include Unidom::Standard::Concerns::AsSourceStandard
include Unidom::Standard::Concerns::AsTargetStandard

As Source Standard concern

The As Source Standard concern do the following tasks for the includer automatically:

1. Define the has_many :target_associatings macro as: has_many :target_associatings, class_name: 'Unidom::Standard::StandardAssociating', foreign_key: :source_id
2. Define the has_many :target_standards macro as: has_many :target_standards, through: :target_associatings, source: :target
3. Define the #associate! method as: associate!(target, due_to: 'REVS', at: Time.now)
4. Define the #associate? method as: associate?(target, due_to: 'REVS', at: Time.now)

As Target Standard concern

The As Target Standard concern do the following tasks for the includer automatically:

1. Define the has_many :source_associatings macro as: has_many :source_associatings, class_name: 'Unidom::Standard::StandardAssociating', foreign_key: :target_id
2. Define the has_many :source_standards macro as: has_many :source_standards, through: :source_associatings, source: :source
3. Define the #is_associated! method as: is_associated!(source, due_to: 'REVS', at: Time.now)
4. Define the #is_associated? method as: is_associated?(source, due_to: 'REVS', at: Time.now)

Disable the Model & Migration

If you only need the app components other than models, the migrations should be neglected, and the models should not be loaded.

# config/initializers/unidom.rb
Unidom::Common.configure do |options|

  options[:neglected_namespaces] = %w{
    Unidom::Standard
  }

end
