Usage in Gemfile:

gem 'unidom-geo'

Run the Database Migration:

rake db:migrate

The migration versions start with 200104.

Call the Model:

Unidom::Geo::Location.valid_at.alive.first.region

active_locatings = location.locatings.valid_at.alive

# Locate: associate a shop, an estate, or a facility with a location
location.locate! shop, by: person
# or
Unidom::Geo::Locating.locate! location: location, located: shop

# Determine whether a shop was located to a given location at a given time.
location.locate? shop, at: Time.now

Include the Concerns:

include Unidom::Geo::Concerns::AsLocated
include Unidom::Geo::Concerns::AsLocator
include Unidom::Geo::Concerns::AsRegion

As Located concern

The As Located concern do the following tasks for the includer automatically:

1. Define the has_many :locatings macro as: has_many :locatings, class_name: 'Unidom::Geo::Locating', as: :located
2. Define the has_many :locations macro as: has_many :locations, through: :locatings, source: :location
3. Define the #is_located! method as: is_located!(to: nil, by: nil, at: Time.now)
4. Define the #is_located? method as: is_located?(to: nil, at: Time.now)

As Locator concern

The As Locator concern do the following tasks for the includer automatically:

1. Define the has_many :locatings macro as: has_many :locatings, class_name: 'Unidom::Geo::Locating', as: :locator
2. Define the has_many :locations macro as: has_many :locations, through: :locatings, source: :location
3. Define the #locate! method as: locate!(it, to: nil, at: Time.now)

As Region concern

The As Region concern do the following tasks for the includer automatically:

1. Define the has_many :locations macro as: has_many :locations, class_name: 'Unidom::Geo::Location'
2. Define the has_many :locatings macro as: has_many :locatings, through: :locations, source: :locatings

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::Geo
  }

end
