Storext Override

This has a specific use case: you want to have another model, most likely a Setting model, that may override the parent model.

class Computer < ActiveRecord::Base
  # If `data` is a PostgreSQL htsore or json store, you don't need to define `store` below.
  store :data, coder: JSON
  include Storext.model

  store_attributes :data do
    manufacturer String, default: "IBM"
  end
end

class Phone < ActiveRecord::Base
  # If `data` is a PostgreSQL htsore or json store, you don't need to define `store` below.
  store :data, coder: JSON

  belongs_to :computer
  include Storext::Override

  storext_override(:computer, :data)
end

class SimCard < ActiveRecord::Base
  store :data, coder: JSON

  belongs_to :phone
  include Storext::Override

  # If you want to override :computer, but it's a not directly associated
  delegate :computer, to: :phone
  storext_override(:computer, :data, class: Komputer)
end

This looks at Computer's data column and copies all accessors into its own, withe override ability.

See spec/storext/override_spec.rb for examples.
